Description

Technical Field

[0001] This invention belongs to the field of low-voltage electrical technology, specifically relating to a switch and a withdrawable switch device and a bypass switch device using the switch. Background Technology

[0002] In the field of electrical technology, switches, such as automatic transfer switches (ATSEs), are used to provide uninterrupted power to loads, switching between different power sources to ensure continuous power supply. Currently, most ATSEs on the market are fixed-type. Fixed-type ATSEs have advantages such as low cost, light weight, ease of wiring for low current, and convenient replacement. However, high-current ATSEs have disadvantages such as large size, heavy weight, and time-consuming maintenance and replacement, making them unsuitable for applications requiring very short power outage times and where the normal operation of critical loads cannot be affected.

[0003] Drawer-type switches are widely used due to their ease of inspection and maintenance. Existing drawer-type switches consist of two parts: a drawer base and a switch body. The switch body is the device that performs closing and opening actions. The drawer base is directly connected to an external power source, and the switch body is connected to the drawer base and then to the external power source. The switch body moves within the drawer base via a rocking-in or rocking-out mechanism, moving between three different positions: connected, test, and disconnected. If the switch body is rocked in or out between these positions, especially between the test and connected positions where it is close to the external power supply terminal block, a closing operation could occur, posing a significant safety risk to the user. Therefore, it is necessary to design a switch body that prevents closing during rocking-in or rocking-out operations, particularly between the test and connected positions, thereby ensuring operational safety.

[0004] Furthermore, in the aforementioned withdrawable switch, a brief power outage for maintenance is necessary when the ATSE (switch body) itself malfunctions, thus reducing the continuity of power supply. To improve power supply continuity and ensure continuous power supply even when the ATSE fails, it is desirable to use a redundant switching mechanism composed of two transfer switches. If one transfer switch fails, the system can promptly switch to the other, resulting in a bypass-type automatic transfer switch. For this switch, it is necessary to install an effective interlocking mechanism to achieve continuous power supply.

[0005] In view of the aforementioned existing technology, it is necessary to make reasonable improvements to the existing switch structure. To this end, the applicant has made beneficial designs, and the technical solution to be introduced below is a product of this background. Summary of the Invention

[0006] The primary objective of this invention is to provide a switch having a stop component that can prevent the latching action so that the contact system cannot close.

[0007] Another objective of this invention is to provide a pull-out switch device that uses such a switch, which, through a stop assembly cooperating with a drawer base, prevents the switch from closing during the rocking-in and rocking-out operation, especially when moving between the test position and the connection position, thereby ensuring safety during operation.

[0008] Another objective of this invention is to provide a bypass-type switch device that uses this type of switch, which achieves mechanical interlocking between the two switches through the cooperation between the stop components in the two switches and the cooperation between the stop components in the two switches and their respective drawer seats, thereby ensuring the accuracy and reliability of the interaction between the switches.

[0009] The primary objective of this invention is achieved as follows: a switch comprising an operating mechanism and a contact system. The operating mechanism includes a closing / opening lever and a latch. Driving the closing / opening lever to a ready position allows the operating mechanism to store energy, and then driving the latch to release energy, thereby causing the contact system to close. The switch also includes a stop assembly comprising a rocker arm assembly and a pusher arm assembly. When the closing / opening lever is in a non-ready position, the lever pushes the rocker arm assembly, placing it in an inner disengaged position outside the latch's movement trajectory, allowing the latch to move. When the closing / opening lever is in the ready position and releases the push on the rocker arm assembly, the rocker arm assembly is in an outer disengaged position outside the latch's movement trajectory. At this time, the pusher arm assembly pushes the rocker arm assembly to a stop position within the latch's movement trajectory, stopping the latch's movement and preventing the contact system from closing.

[0010] In a specific embodiment of the present invention, the switch includes a right inner side plate, the contact system, the operating mechanism and the right inner side plate are arranged in sequence, the push rod assembly is rotatably disposed on the side of the right inner side plate opposite to the operating mechanism, and the swing rod assembly is rotatably disposed on the top of the right inner side plate, one end of which cooperates with the push rod assembly located on one side of the right inner side plate, and the other end extends to the other side of the right inner side plate to cooperate with the closing / opening lever.

[0011] In another specific embodiment of the present invention, the rocker arm assembly includes a bracket, a rocker arm, a drive spring, and a rocker arm return spring. The bracket consists of a fixed surface and a mounting surface. The fixed surface is fixed to the right inner side plate. The rocker arm is rotatably mounted on the mounting surface via a pivot shaft. One end of the rocker arm extending toward the operating mechanism forms a locking end, which engages with a latch. The other end of the rocker arm extending away from the operating mechanism forms a rocker arm drive end, which engages with a push rod assembly. The drive spring is a torsion spring, with its middle portion sleeved on the pivot shaft. One end engages with the opening / closing lever, and the other end is hung on the rocker arm drive end. The rocker arm return spring is a tension spring, with one end hung on the right inner side plate and the other end... The end is hung on the swing arm drive end; a limit groove is opened at the top of the right inner side plate. When the closing / opening lever is in the non-ready position, the closing / opening lever acts on the drive spring, causing the swing arm to overcome the tension of the swing arm return spring and abut against the first limit wall of the limit groove. The swing arm assembly is in the inner disengagement position. When the closing / opening lever is in the ready position, the closing / opening lever releases the pressure on the swing arm assembly. Under the action of the swing arm return spring, the swing arm abuts against the second limit wall of the limit groove. The swing arm assembly is in the outer disengagement position. At this time, the push rod assembly pushes the swing arm to overcome the tension of the swing arm return spring and move to the stop position between the inner disengagement position and the outer disengagement position.

[0012] In another specific embodiment of the present invention, the push rod assembly includes a push rod and a push rod return spring. The push rod is rotatably mounted on the right inner side plate via a push rod assembly pivot shaft. One end of the push rod extends toward the swing rod drive end of the swing rod to form a first drive end, and the other end is provided with a push rod limiting groove. The push rod limiting groove cooperates with the push rod assembly limiting shaft on the right inner side plate. The push rod return spring is a torsion spring, with its middle part sleeved on the push rod assembly pivot shaft. One end is hung on the right inner side plate, and the other end is hung on the first drive end. The push rod return spring acts on the first drive end, causing the push rod assembly limiting shaft to abut against the first limiting wall of the push rod limiting groove. The push rod assembly does not push the swing rod assembly to the stop position within the hook-and-loop movement trajectory. When the push rod overcomes the action of the push rod return spring and causes the push rod assembly limiting shaft to abut against the second limiting wall of the push rod limiting groove, the push rod assembly pushes the swing rod assembly to the stop position within the hook-and-loop movement trajectory.

[0013] In another specific embodiment of the present invention, the operating mechanism further includes an output spindle, which drives the moving contact in the contact system to rotate, thereby realizing the closing and opening of the moving contact and the stationary contact; the switch is a dual power supply changeover switch, and its operating mechanism is symmetrically arranged with the output spindle with a first spring mechanism corresponding to the first power supply and a second spring mechanism corresponding to the second power supply, each spring mechanism including the closing / opening lever and the latch; the rocker arm assembly is a pair, symmetrically arranged on both sides of the output spindle; the push rod assembly is a pair, symmetrically arranged on both sides of the output spindle.

[0014] Another objective of the present invention is achieved by providing a pull-out switch device comprising a switch and a drawer base, the switch being movable within the drawer base and having three positions relative to the drawer base: separated, test, and connected. A pair of limiting members are fixed on a drawer base side plate on one side corresponding to the right inner side plate of the drawer base, each engaging with its corresponding push rod assembly. When the switch moves between the test and connected positions, the limiting members push the push rod assembly to rotate, thereby pushing the lever assembly to a stop position within the latch action trajectory.

[0015] In a further specific embodiment of the present invention, the switch further includes a right outer side plate and a left outer side plate, the left outer side plate, the contact system, the operating mechanism, the right inner side plate and the right outer side plate are arranged in sequence, and a plurality of guide posts are fixed on the right outer side plate and the left outer side plate; a pair of guide rails are respectively provided on a pair of drawer side plates of the drawer seat, and a sliding groove for the guide posts to slide is formed between the pair of guide rails.

[0016] In another specific embodiment of the present invention, the switch further includes a closing / opening output drive mechanism. The closing / opening output drive mechanism is located between the operating mechanism and the right inner side plate and rotates synchronously with the output main shaft of the operating mechanism. It includes a turntable, the middle of which is connected to the output main shaft. The two ends of the turntable are provided with a first drive shaft and a second drive shaft. The first drive shaft and the second drive shaft are symmetrical about the rotation center. A pair of arc grooves are symmetrically provided on the right inner side plate, which are respectively the first drive shaft movement groove and the second drive shaft movement groove. After the first drive shaft and the second drive shaft protrude from the first drive shaft movement groove and the second drive shaft movement groove, they cooperate with their respective push rod assemblies. The pair of push rods are also respectively provided with closing / opening output drive ends. The first drive shaft and the second drive shaft cooperate with the closing / opening output drive ends of their respective push rods.

[0017] Another objective of the present invention is achieved as follows: a bypass-type switching device includes two pull-out switching devices as described in the claims and a drawer frame. The two pull-out switching devices are arranged vertically relative to each other within the drawer frame along the Z-axis. Each pull-out switching device includes a switch and a drawer base. The switch located above is called the upper switch, and the switch located below is called the lower switch. On the drawer base side plate of the drawer base where the upper switch is installed, a pair of interlocking plates are rotatably provided at a position corresponding to the right inner side plate of the upper switch. Each interlocking plate corresponds to a first spring mechanism and a second spring mechanism of the upper switch, respectively. On the drawer base side plate of the drawer base where the lower switch is installed, a pair of interlocking plates are rotatably provided at a position corresponding to the right inner side plate of the lower switch. A pair of interlocking plates are rotatably mounted on the plate, each corresponding to the first spring mechanism and the second spring mechanism of the lower switch. Each pair of interlocking plates has the same structure and is symmetrically arranged. The interlocking plate of the first spring mechanism of the upper switch is connected to the interlocking plate of the first spring mechanism of the lower switch by an interlocking lever, and the interlocking plate of the second spring mechanism of the upper switch is connected to the interlocking plate of the second spring mechanism of the lower switch by another interlocking lever. The two interlocking plates of the upper pull-out switch device are linked with the push rod assembly when the upper switch reaches the connection position, and the two interlocking plates of the lower pull-out switch device are linked with the push rod assembly when the lower switch reaches the connection position.

[0018] In a further specific embodiment of the present invention, when the first power supply of the upper switch is closed and the second power supply is open, the closing / opening lever in the first spring mechanism of the upper switch is in the lower ready position and releases the pressure on the rocker arm assembly corresponding to the first spring mechanism. The rocker arm assembly is in the outer disengaged position outside the latch action trajectory in the first spring mechanism. The closing / opening lever in the second spring mechanism is in the upper non-ready position and pushes the rocker arm assembly corresponding to the second spring mechanism. The rocker arm assembly is in the inner disengaged position outside the latch action trajectory in the second spring mechanism. The first drive shaft in the closing / opening output drive mechanism that follows the output main shaft releases the pressure on the push rod assembly corresponding to the first spring mechanism. The push rod assembly does not push the rocker arm assembly to the stop position within the latch action trajectory. The second drive shaft pushes the second spring... The push rod assembly corresponding to the spring mechanism pushes the rocker arm assembly to the stop position within the latch action trajectory. Due to the transmission of the interlocking plate and interlocking lever, the two push rod assemblies of the lower switch and the two push rod assemblies of the upper switch have the same position. When the lower switch is in the double-open position with its first power open and second power open, and the closing lever in the second spring mechanism of the lower switch is in the lower ready position and releases the push on the rocker arm assembly corresponding to the second spring mechanism, the rocker arm assembly on this side is in the outer disengagement position outside the latch action trajectory in the second spring mechanism. Due to the first power close and the second power open of the upper switch, the push rod assembly corresponding to the second spring mechanism pushes the rocker arm assembly to the stop position within the latch action trajectory. The stop latch action prevents the second power of the lower switch from being closed.

[0019] The present invention, due to the adoption of the above-mentioned structure, has the following beneficial effects: First, a stop assembly is set in the switch, which includes a rocker arm assembly and a push rod assembly. When the switch moves between the test position and the connection position relative to the drawer seat, the action of the push rod assembly pushed by the limiting member on the drawer seat to the drive position pushes the rocker arm assembly to the stop position within the latching action trajectory. The stop latching action prevents the contact system from closing, thereby ensuring safety during operation. Second, in the bypass type switch device, the stop assembly cooperates with the interlocking plate on the drawer seat for transmission, and then through the transmission of the interlocking lever connected between the two pull-out switch devices, the mechanical interlock of the two switches is realized, ensuring the accuracy and reliability of the mutual action between the switches.

[0080] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the applicant's description of the embodiments is not intended to limit the technical solution. Any formal but not substantive changes made based on the concept of the present invention should be considered within the scope of protection of the present invention.

[0081] In the following description, all directional or orientational concepts involving up, down, left, right, front, and back are based on the positions shown in the corresponding figures, and therefore should not be construed as a special limitation on the technical solutions provided by this invention.

[0082] When dealing with the X, Y, and Z axes, the horizontal direction shown in Figure 1 is taken as the X-axis. Figure 3The vertical direction shown is the Z-axis, and the direction that is perpendicular to both the X-axis and the Z-axis is the Y-axis.

[0083] Please see Figures 1a to 3 This invention relates to a switch 100, which includes an operating mechanism 1 and a contact system 2. The switch 100 is a dual-power transfer switch with three positions: first power closed, second power closed, and dual open. The operating mechanism 1 includes a first spring mechanism corresponding to the first power and a second spring mechanism corresponding to the second power. The first and second spring mechanisms have the same structure and are symmetrically arranged corresponding to the output main shaft 13 of the operating mechanism 1. As is known in the art, the operating mechanism 1 includes a pair of side plates. Each spring mechanism includes a closing / opening lever 11 rotatably mounted on the pair of side plates, an upper connecting rod rotatably mounted on the pair of side plates, a lower connecting rod hinged to the upper connecting rod, a mechanism spring connected to the hinge shaft of the closing / opening lever 11 and the upper and lower connecting rods, a latch 12 rotatably mounted on the mechanism side plate, and a jumper that cooperates with the latch 12 and the upper connecting rod. The lower connecting rod of each spring mechanism is connected to the output main shaft 13.

[0084] like Figure 3 As shown, the lower closing / opening lever 11 is specifically the first closing / opening lever 110 corresponding to the first power supply, and the upper closing / opening lever 11 is specifically the second closing / opening lever 110' corresponding to the second power supply. The lower latch 12 is specifically the first latch 120 corresponding to the first power supply, and the upper latch 12 is specifically the second latch 120' corresponding to the second power supply.

[0085] like Figure 2 , Figure 3 As shown, the contact system 2 of the switch 100 includes a rotatably disposed moving contact 22 and a pair of stationary contacts disposed on both sides of the moving contact. The first stationary contact 23 is connected to the first power supply terminal, and the second stationary contact 23' is connected to the second power supply terminal. The moving contact 22 is connected to the load terminal via a flexible connecting wire. The switching process of the switch 100 is as follows: The switching process begins when the switch 100 is in the double-open position and the first spring mechanism is in the closed ready state. At this time, the opening / closing lever 11 in the first spring mechanism is in the lower ready position, and the opening / closing lever 11 in the second spring mechanism is in the upper non-ready position. The latch 12 and the trip latch in the first spring mechanism are locked. At this time, the latch 12 can be manually pressed or electrically triggered (refer to...). Figure 11As shown, the latch 12 in the first spring mechanism, i.e., the first latch 120, rotates counterclockwise to unlock the latch, thereby releasing energy from the first spring mechanism. This causes the output spindle 13 to rotate counterclockwise, and the output spindle 13 causes the moving contact 22 to close with the first stationary contact 23, thus closing the first power supply. When switching the power supply is required, the connecting rod between the closing / opening lever 11 of the first spring mechanism and the closing / opening lever 11 of the second spring mechanism is manually moved, or the closing / opening lever 11 of the second spring mechanism is moved to the lower position by the electromagnet on the side of the second spring mechanism. In the ready position, the opening / closing lever 11 of the first spring mechanism is driven to the upper non-ready position by the connecting rod. The latch 12 and trip latch in the first spring mechanism reset, while the latch 12 and trip latch in the second spring mechanism remain locked to each other. The spring mechanisms on both sides drive the output main shaft 13 to rotate clockwise to the middle position. The moving contact 22 separates from the stationary contacts on both sides, and the switch 100 is in the double-open position. The second spring mechanism has completed its energy storage and reached the ready position for closing. At this time, manually pressing or electrically triggering the corresponding latch 12 of the second spring mechanism... (Refer to...) Figure 11 As shown, the second spring mechanism's corresponding latch 12, i.e., the second latch 120', rotates clockwise to unlock, thereby releasing energy from the second spring mechanism. This causes the output spindle 13 to rotate clockwise, which in turn causes the moving contact 22 and the second stationary contact 23' to close, closing the second power supply and completing the switch from closing the first power supply to closing the second power supply. For details, please refer to CN209133376U.

[0086] like Figure 2 , Figure 32a , Figure 32b , Figure 33As shown, the contact system 2 is located on the left side of the operating mechanism 1 and adopts a single-pole modular design, including multiple contact modules. Each contact module includes a base 21, a moving contact 22, a first stationary contact 23 corresponding to the first power supply, a second stationary contact 23' corresponding to the second power supply, an arc-extinguishing chamber 24, a partition 25, and a rear lead-out connector 26. The base 21 adopts a left-right interlocking structure and is secured with screws. The internal cavity formed after the base 21 is assembled encloses the moving contact 22, the first stationary contact 23, the second stationary contact 23', and the arc-extinguishing chamber 24. The system includes chamber 24, partition 25, and rear exit terminal 26. The normally reserved stationary contact assembly inlet bar 231 and load-side outlet bar 232 are respectively located on both sides of the moving contact 22. The first stationary contact 23 and the second stationary contact 23' are arranged vertically. The first stationary contact connecting plate 233 on the lower side is shorter than the second stationary contact connecting plate 234 on the upper side. The rear exit terminal 26 is directly fixed to the normally reserved stationary contact assembly inlet bar 231 and the load-side outlet bar 232, and then protrudes from the bottom of the base 21, forming an insert-type contact module. The rear exit terminal 26 includes a first power supply rear exit terminal 263, a second power supply rear exit terminal 264, and a load rear exit terminal 265. The first power supply rear exit terminal 263 and the second power supply rear exit terminal 264 are separated by a base boss 211. Figure 35 As shown, to reduce the overall volume, the insertion end 261 of the first stationary contact 23 is rotated towards the rotation center side of the moving contact via the adapter 262, thereby moving the first power supply rear outlet pin 263 away from the second power supply rear outlet pin 264. On the base 21, an exhaust port 271 and a recessed cavity 28 are provided near the first arc nozzle 27 of the first stationary contact 23. When the contact modules are assembled, the exhaust port 271 and the recessed cavity 28 form the first exhaust channel 272 of the first stationary contact 23. The second power supply rear outlet pin 264 is housed in the second power supply rear outlet pin mounting cavity 213 inside the base 21, and is isolated from the first exhaust channel 272 by the base boss 211, so that the gas ejected from the first stationary contact 23 bypasses the second power supply rear outlet pin 264 and is ejected from the upper surface of the base 21. Figure 1b The first exhaust channel 272 is located on the upper part. The upper and lower end faces of the contact system 2 adopt an open design to facilitate the internal airflow from bottom to top, and are enclosed by a perforated arc-damping plate 25 to prevent foreign objects from entering.

[0087] like Figure 2 As shown, the switch 100 includes a left outer side plate 1004, an indicator module 1007, a left inner side plate 1003, a contact system 2, an operating mechanism 1, a closing / opening output drive mechanism 4, a right inner side plate 1001, a stop assembly 3 disposed on the right inner side plate 1001, and a right outer side plate 1002. The above components are arranged sequentially in the X-axis direction.

[0088] like Figure 2 As shown, the left inner side plate 1003 is installed on the outside of the contact system 2, and the left inner side plate 1003, the contact system 2, and the operating mechanism 1 are fixed together by screws. The indicator module 1007 is provided with an indicator device that provides feedback on the contact position status of the contact system 2, and the indicator module 1007 is fixed on the left inner side plate 1003.

[0089] like Figure 2 , Figure 20 , Figure 32b As shown, a connecting plate 1008 is provided on the back of the indicator module 1007. The connecting plate 1008 engages with the contact positioning boss 214 on the base 21 of the contact system 2 via a contact positioning groove 10081 on it, and the left inner side plate 1003 is fixed to the connecting plate 1008 via a left inner side plate mounting hole 10083. The left outer side plate 1004 is installed on the outside of the indicator module 1007. A left outer side plate positioning boss 10082 is also provided on the connecting plate 1008, which is positioned with the left outer side plate positioning groove 10041 on the left outer side plate 1004. The plate is fixed by screws passing through the fixing mounting holes on the left outer side plate 1004, the mounting holes on the indicator module 1007, and the mounting holes on the left inner side plate 1003, respectively.

[0090] like Figure 3 As shown, the upper left outer side plate 1004 and the upper right inner side plate 1001 are also provided with transport holes 1009 for transporting the switch 100. Figure 5 As shown, a clearance hole 100121 for the wiring terminals of the switch body contact group 67 is also provided on the right inner side plate 1001.

[0091] like Figure 2 , Figure 19 As shown, a manual / automatic housing assembly 18 is also installed above the operating mechanism 1. The manual / automatic housing assembly 18 has two sides for avoidance interlocking drive and contact module drive, forming a through-cavity structure 181. The manual / automatic housing assembly 18 is equipped with a manual / automatic switching knob, an isolation padlock device, and a manual operation window, which cooperate with the operating mechanism 1. A face cover 19 is also provided above the manual / automatic housing assembly 18. The face cover 19 is provided with a contact position indicator window 191 and a manual / automatic operation window 192. An insulating partition 182 is provided at the upper end of the manual / automatic housing assembly 18 near the first exhaust channel 272. Figure 1a , 1c The two sides 193 of the cover 19 protrude from the right outer side plate 1002 and the left outer side plate 1004. When the switch body is pulled out from the drawer seat, the two sides 193 can serve as handles.

[0092] like Figure 14As shown, the latch 12 is symmetrically arranged with the output spindle 13 of the operating mechanism 1 as the center. The latch 12 is provided with an electric drive end 122, a manual drive end 123, a limiting boss 121, a latch surface 124 and a rotation center hole 125. The electric drive end 122 and the manual drive end 123 are respectively located on both sides of the rotation center hole 125. The limiting boss 121 is located between the latch rotation center 125 and the manual drive end 123. The latch surface 124 is located between the rotation center 125 and the electric drive end 122.

[0093] The switch 100 of the present invention is characterized by the addition of a pair of symmetrically arranged stop components 3. The pair of stop components 3 correspond to the first power supply and the second power supply respectively. Each set of stop components 3 includes a rocker arm assembly 31 and a push rod assembly 32. Therefore, the rocker arm assemblies 31 in the two sets of stop components 3 are symmetrically arranged on both sides of the output main shaft 13 and have the same components. The push rod assemblies 32 in the two sets of stop components 3 are symmetrically arranged on both sides of the output main shaft 13 and have the same components.

[0094] like Figures 3 to 10 As shown, the rocker arm assembly 31 includes a bracket 311, a rocker arm 312, a drive spring 313, and a rocker arm return spring 314. The bracket 311 is shaped like a ┑ and consists of a fixed surface 3111 and a mounting surface 3112. The fixed surface 3111 is fixed to the right inner side plate 1001. The rocker arm 312 is rotatably mounted on the mounting surface 3112 via a pivot shaft 3121. Specifically, the first pivot shaft segment 31211 passes through the pivot hole 3125 and the bushing hole 31241 of the bushing 3124, and the second pivot shaft segment 31212 is mounted on the mounting surface 3112. The mounting hole 31122 is fixed, wherein the first bushing section 31242 is located between the rocker arm 312 and the bracket 311 and the drive spring 313 is sleeved on the outer circumference. The second bushing section 31243 is engaged with the pivot hole 3125. The end of the rocker arm 312 extending toward the operating mechanism 1 constitutes the locking end 3122. At the end of the locking end 3122, a rocker arm interlocking boss 31221 is bent to ensure that the rocker arm interlocking boss 31221 can extend to the side of the buckle 12 and below the limiting boss 121, that is, to ensure reliable engagement with the buckle 12. One end of the rocker arm 312 extending away from the operating mechanism 1 constitutes the rocker arm drive end 3123. The end of the rocker arm drive end 3123 is bent downwards, and a rocker arm drive shaft 31231 is fixed at the bend to reliably cooperate with the first drive end 3212 of the push rod assembly 32. The rocker arm drive end 3123 forms the signal switch drive end face 31232 of the closing ready signal switch 60 (see...). Figure 9The drive spring 313 is a torsion spring, with its middle part sleeved on the pivot shaft 3121. One end engages with the opening / closing lever 11, and the other end is hung on the swing arm drive end 3123. The swing arm return spring 314 is a tension spring, with one end hung on the right inner side plate 1001 and the other end hung on the swing arm drive end 3123.

[0095] like Figure 4 , Figure 7 As shown, a limiting groove 10011 is formed at the top of the right inner side plate 1001. When the closing / opening lever 11 is in the upper non-ready position, the closing / opening lever 11 acts on the drive spring 313, causing the rocker arm 312 to overcome the tension of the rocker arm return spring 314 and abut against the first limiting wall 100111 near the outer side of the limiting groove 10011. The rocker arm assembly 31 is in the inner disengaged position, as shown. Figure 28b As shown in the right-hand side of the diagram, when the closing / opening lever 11 is in the lower ready position, the closing / opening lever 11 releases its pressure on the swing arm assembly 31. Under the action of the swing arm return spring 314, the swing arm 312 abuts against the second limiting wall 100112 near the inner side of the limiting groove 10011, and the swing arm assembly 31 is in the outward disengaged position. Figure 28b As shown in the left-hand side of the center, the pusher assembly 32, moving towards the drive position, pushes the swing arm 312 against the tension of the swing arm return spring 314 to a stop position between the inner and outer disengagement positions. The drive position here refers to the position where the pusher assembly 32 pushes the swing arm assembly 31 to the stop position within the movement trajectory of the latch 12. The non-drive position, as described below, refers to the position where the pusher assembly 32 does not push the swing arm assembly 31 to the stop position within the movement trajectory of the latch 12.

[0096] like Figure 7 , Figure 8 As shown, on the bracket 311 of the rocker arm assembly 31, at the bend connection between the mounting surface 3112 and the fixing surface 3111, there is a rocker arm positioning boss 31121 extending from the mounting surface. It is accommodated in the rocker arm assembly positioning groove 100113 opened on the right inner side plate 1001 below the rocker arm assembly limiting groove 1011. This prevents the rocker arm 312 from being tilted up by force during rotation, which would prevent the rocker arm interlocking boss 31221 from moving below the limiting boss 121 of the buckle 12. In other words, it prevents the rocker arm interlocking boss 31221 from failing to enter the movement trajectory of the buckle 12, thus preventing the locking failure.

[0097] like Figure 5 , Figure 6 , Figure 10 , Figure 18As shown, the push rod assembly 32 includes a push rod 321 and a push rod return spring 322. The push rod 321 is rotatably mounted on the right inner side plate 1001 via a push rod assembly pivot shaft 10013. One end of the push rod 321 extends towards the swing rod drive end 3123 of the swing rod 312 to form a first drive end 3212, and the other end extends in the opposite direction to form a second drive end 3213. A push rod drive shaft 32131 is provided at the end of the second drive end 3213 to ensure reliable cooperation with the limiting member 2006. An arc-shaped push rod limiting groove 3211 is also provided on the second drive end 3213, which cooperates with the push rod assembly limiting shaft 10014 on the right inner side plate 1001. The push rod return spring 322 is a torsion spring, with its middle part sleeved on the push rod assembly pivot shaft 10013, one end hanging on the right inner side plate 1001, and the other end hanging on the first drive end 3212. The push rod return spring 322 acts on the first drive end 3212, causing the push rod assembly limiting shaft 10014 to abut against the first limiting wall 32111 near the inner side of the push rod limiting groove 3211. The push rod assembly 32 is in a non-driven position. When the limiting member 2006 (described below) drives the push rod 321 to overcome the action of the push rod return spring 322, causing the push rod assembly limiting shaft 10014 to abut against the second limiting wall 32112 near the outer side of the push rod limiting groove 3211, the push rod assembly 32 is in a driven position. A pair of drive shaft movement grooves 10021, symmetrically arranged with respect to the output spindle 13, are provided on the right outer plate 1002 for the push rod drive shaft 32131 to pass through the right outer plate 1002 and engage with the limiting member 2006 on the drawer seat 200 (mentioned below).

[0098] like Figure 2 , Figure 5 , Figure 6 , Figure 11 As shown, the right inner side plate 1001 and the operating mechanism 1 are fixedly connected through the cooperation of the positioning post 14 of the operating mechanism 1 and the positioning hole 10016 on the right inner side plate 1001, the positioning boss 15 on the mounting side plate 16 of the operating mechanism 1 and the positioning strip hole 10017 on the right inner side plate 1001, and the screws passing through the screw hole 162 on the side plate lower bending plate 161 of the mounting side plate 16 of the operating mechanism 1 and the screw hole on the mounting foot 100120 on the right inner side plate 1001, so that the operating mechanism 1 is located between the right inner side plate 1001 and the mounting side plate 16. An auxiliary closing mechanism 17 is also provided between the operating mechanism 1 and the mounting side plate 16 to realize the reliable closing of the switch 100. A position signal module 5 and the closing and opening output drive mechanism 4 described below are provided between the operating mechanism 1 and the right inner side plate 1001. The other end of the output spindle 13 of the operating mechanism 1 is connected to the camshaft 50 to realize the output of switch signals and interlocking action output.

[0099] like Figure 21In a withdrawable switchgear, the switch body's closing / opening operating handle 303 is fixed to one side of the drawer base 200; for example... Figure 23 In the bypass type switchgear, the switch body's closing and opening operation handle 303 is fixed to one side of the drawer 300.

[0100] The switch 100 described above, taking a dual-power transfer switch as an example, has an internal stop assembly 3. The switch 100 will be further described below through various application examples:

[0101] Application Example 1:

[0102] like Figure 21 , Figure 22 As shown, the device described in this application example is a pull-out switch device in which a switch 100 is installed. It includes a switch 100 and a drawer base 200. The drawer base 200 includes a base plate 2001, a pair of drawer base side plates 2003, a top plate and a base frame. A gear transmission assembly 2002 is provided on the base plate 2001. Through the action of the gear transmission assembly 2002, the switch 100 can be rocked in and out relative to the drawer base 200. The switch 100 has three positions relative to the drawer base 200: separated, tested, and connected.

[0103] like Figure 2 , Figure 3 , Figure 15 , Figure 16 , Figure 18 As shown, to ensure the smooth movement of the switch 100 within the drawer seat 200, multiple guide posts 1005 arranged along the Y-axis are fixed on the side of the right outer panel 1002 and the left outer panel 1004 facing the drawer seat 200, and a drive post 1006 is also fixed thereon. The drive post 1006 includes a drive post shaft 10061, a roller 10062 sleeved on the drive post shaft 10061, and a limiting piece 10063 fixed to the end of the drive post shaft 10061 to prevent the roller 10062 from disengaging. Figure 22 As shown, the drawer seat 200 has a gear transmission assembly 2002 on its base plate 2001. A pair of guide rails 2004 are respectively provided on a pair of drawer seat side plates 2003 of the drawer seat 200. A sliding groove 2005 is formed between the pair of guide rails 2004, allowing the guide posts 1005 of both the right outer side plate 1002 and the left outer side plate 1004 to slide. The guide posts 1005 can slide along the guide rails 2004 on the drawer seat 200, thereby pushing the switch 100 to easily insert or remove it from the drawer seat 200, achieving smooth movement of the switch 100 within the drawer seat 200. The drive post 1006 is driven by a gear guide plate 20021 on the drawer seat 200. Figure 16 , Figure 22A guide post stop wall 10053 is provided at the end of the guide post 1005, which cooperates with the side of the guide rail 2004 facing the drawer seat side plate 2003 to limit the guide post.

[0104] As Figure 5 ,、 Figure 15 , Figure 16 , Figure 18 , Figure 22 As shown, reinforcing plates 10051 are also provided on the left outer side plate 1004 and the right outer side plate 1002. The reinforcing plates 10051 are riveted to the right outer side plate 1002 or the left outer side plate 1004 via guide posts 1005 to prevent the guide posts 1005 from bending due to excessive force arm of the gear guide plate 20021. The reinforcing plates 10051 are also provided with a switch anti-flip limiting groove 10052, which cooperates with the limiting boss 20051 on the drawer seat 200 and works together with the guide posts 1005 to prevent the switch 100 from flipping due to excessive force during the insertion of the main circuit. A notch 10028 is provided at the upper end of the right outer side plate 1002, forming a cavity with the right inner side plate 1001 to accommodate the signal line output of the drawer seat 200. Since several microswitches are fixed on the right inner side plate 1001, such as: first closing ready signal switch 60, first closing signal switch 61, second closing signal switch 62, first auxiliary signal switch 63, and second auxiliary signal switch 64, corresponding to the position of each microswitch, microswitch mounting screw clearance holes 10029 are provided on the right outer side plate 1002.

[0105] like Figure 2 , Figure 17 On the side of the left outer side plate 1004 facing the contact system 2, there are two pairs of mounting parts 10042. Each pair of mounting parts 10042 is fitted with a screw. Specifically, the screw passes through the screw hole on the upper mounting part 100421 of the mounting part 10042, the screw hole on the upper surface 10071 of the mounting boss of the indicator module 1007, the screw hole on the lower surface 10072 of the mounting boss of the indicator module 1007, the screw hole 100311 on the flange 10031 of the left inner side plate 1003, and the left inner side plate mounting hole 10083 on the connecting plate 1008, and is then screwed into the screw hole on the lower mounting part 10042 of the mounting part 10042, thereby fixing the left outer side plate 1004, the indicator module 1007, the left inner side plate 1003, and the connecting plate 1008.

[0106] like Figure 8 , Figure 22As shown, to ensure that the switch 100 cannot be closed during its movement from the test position to the connection position (i.e., neither the first power supply nor the second power supply can be closed), a pair of limiting members 2006 are fixed on the drawer seat side plate 2003 on the side corresponding to the right inner side plate 1001 of the drawer seat 200. These limiting members 2006 cooperate with the push rod assembly 32 of their respective corresponding stop assemblies 3. When the switch 100 moves between the test position and the connection position, the limiting members 2006 push the push rod assembly 32 to rotate to the drive position, and the push rod assembly 32 pushes the swing arm assembly 31 to the stop position. This stop position is located at the latch 12 corresponding to the first spring mechanism, i.e., the first latch 120. Figure 11 On the counterclockwise rotation trajectory shown, similarly, for the second spring mechanism side, the stop position of the rocker arm assembly 31 is located at the buckle 12 corresponding to the second spring mechanism, i.e., the second buckle 120'. Figure 11 As shown in the clockwise rotation trajectory, the latch 12 cannot be driven to unlock from the jumper, and the corresponding spring mechanism cannot release energy to drive the output spindle 13 to rotate, thus making it impossible for the switch 100 to close.

[0107] like Figure 22 , Figure 25a , Figure 25bAs shown, a pair of limiting members 2006 of the drawer seat 200 are respectively disposed on the upper and lower sides of a pair of guide rails 2004. Along the Y-axis direction of the switch 100, starting from the outer side near the opening of the drawer seat 100, an inlet section 20061, a separation test section 20062, a test connection section 20063, and a connection section 20064 are sequentially provided. The test connection section 20063 protrudes relative to the separation test section 20062 and the connection section 20064. That is, the distance between the pair of limiting members 2006 at the test connection section 20063 is less than the distance between them at the separation test section 20062, and similarly less than the distance between them at the connection section 20064. A transition section one 20065 is provided between the separation test section 20062 and the test connection section 20063, and a transition section two 20066 is provided between the test connection section 20063 and the connection section 20064. The separation test section 20062 and the connecting section 20064 are on the same plane. When the switch 100 just enters the drawer seat 200, the push rod drive shaft 32131 cooperates with the guide section 20061. When the switch 100 reaches the separation position and moves from the separation position to the test position, in both of the above two stages, the push rod return spring 322 acts on the first drive end 3212, causing the push rod assembly limiting shaft 10014 to abut against the first limiting wall 32111 of the push rod limiting groove 3211, and the push rod assembly 32 is in the non-drive position. As the switch 100 further enters the drawer seat 200 and moves from the test position to the connection position, the test connection section 20063 pushes the push rod drive shaft 32131, causing the push rod 321 to overcome the action of the push rod return spring 322 and rotate towards the drive position. This causes the push rod assembly limiting shaft 10014 to abut against the second limiting wall 32112 near the outer side of the push rod limiting groove 3211, and the push rod assembly 32 is in the drive position.

[0108] In this application example, the closing / opening output drive mechanism 4 may not be provided in the main switch 100. The closing / opening output drive mechanism 4 will be described in detail in the second application example below.

[0109] Application Example 2:

[0110] like Figure 23As shown, this embodiment describes a bypass-type switch device with two switches 100 installed. It includes two switches 100, two drawer seats 200, and a drawer rack 300. The two switches 100 are respectively installed in the drawer seats 200, forming two pull-out switch devices as described in Application Example 1. The two pull-out switches are arranged vertically along the Z-axis within the drawer rack 300. In this application example, the drawer rack 300 consists of a pair of side plates, specifically a left side plate 301 and a right side plate 302. The drawer rack 300 fixes the two pull-out switch devices, and the two switches 100 bypass each other. The left and right side plates are located on both sides of the two stacked switches. Here, the switch 100 located above is referred to as the upper switch, and the switch 100 located below is referred to as the lower switch. Both switches 100 can be moved in and out of their respective drawer seats 200. The left and right side plates are fixed to the drawer seats corresponding to the upper and lower switches, respectively. Specifically, screw 71 passes through through holes 72 on the left and right side plates, and through holes 73 on the drawer side plates of the upper and lower switches, and is then tightened with nuts on the inside of the drawer side plates to fix and position the first and second switches. Both the upper and lower switches are pull-out type changeover switches, and can be designated as either the main circuit changeover switch (ATSE) or the bypass switch (RTSE) via a controller, allowing them to bypass each other. The operating principle of the bypass-type automatic changeover switch is as follows: The changeover switch requiring maintenance is designated as ATSE, and the other is designated as RTSE. Then, the corresponding side of the RTSE is closed, at which point both ATSE and RTSE are in operation. Next, the ATSE is opened and moved to a test position for operational testing. Furthermore, the ATSE can be moved to an isolated position and disconnected from the entire power supply network.

[0111] Therefore, in Application Example 1, during the movement of switch 100 from the test position to the connected position, switch 100 cannot be closed, that is, neither the first power supply nor the second power supply can be closed. Therefore, this application example also needs to set the structure described in Application Example 1. In addition to the above structure, when both switches 100 are in the connected position relative to the drawer seat 200, in order to ensure the interlocking function between them, that is, when the first power supply of one switch 100 is closed, the second power supply of the other switch 100 is not allowed to be closed, it is necessary to add some components based on the above structure, including: a closing / opening output drive mechanism 4 needs to be set in switch 100, a closing / opening output drive end 3214 cooperating with the closing / opening output drive mechanism 4 is added to the push rod assembly 32 in addition to the structure of Application Example 1, an interlocking plate 2007 is set on the drawer seat 200, and an interlocking lever 2008 is set between the interlocking plate 2007 of the corresponding upper switch and the interlocking plate 2007 of the corresponding lower switch.

[0112] like Figure 2 , Figure 7 , Figure 11 , Figure 12 As shown, the closing / opening output drive mechanism 4 is located between the operating mechanism 1 and the right inner side plate 1001 and rotates synchronously with the output main shaft 13 of the operating mechanism 1. It includes a turntable 41, the middle of which is connected to the output main shaft 13. The two ends of the turntable 41 are provided with a first drive shaft 411 and a second drive shaft 412. The first drive shaft 411 and the second drive shaft 412 are symmetrical about the rotation center. A pair of arc grooves are symmetrically provided on the right inner side plate 1001, namely the first drive shaft movement groove 10012 and the second drive shaft movement groove 10012'. After the first drive shaft 411 and the second drive shaft 412 protrude from the first drive shaft movement groove 10012 and the second drive shaft movement groove 10012' respectively, they cooperate with their respective push rod assemblies 32.

[0113] like Figure 4 , Figure 12 As shown, a connecting rod 42 is also hinged to the first drive shaft 411 of the turntable 41. The connecting rod 42 has recessed clearance notches 422 on both sides to allow the positioning post 14 to pass through during rotation. A third drive shaft 421 is located at the other end of the connecting rod 42. A third drive shaft movement groove 10015 is provided on the right inner side plate 1001 for the third drive shaft 421 to pass through. Similarly, a long straight groove 10025 is provided at a corresponding position on the right outer side plate 1002 for the third drive shaft 421 to pass through and engage with the drawer locking device on the drawer side plate 2003 of the drawer seat 200. Thus, the opening / closing output drive mechanism 4 is located between the operating mechanism 1 and the right inner side plate 1001, and it moves with the output main shaft 13. Figure 4 As shown, the first drive shaft 411 outputs the first power supply on / off signal, for example in... Figure 4In this circuit, when the first power supply is closed, the first drive shaft 411 is located at the lower end of the first drive shaft movement groove 10012, and when the second power supply is open, the second drive shaft 412 is located at the upper end of the second drive shaft movement groove 10012'. At this time, the third drive shaft 421 is located near the output main shaft 13, outputting a signal that the entire switch is in the closed state. Of course, when the second power supply is closed, the second drive shaft 412 will be located at the lower end of the second drive shaft movement groove 10012', while the first power supply is in the open state, and the first drive shaft 411 is located at the lower end of the first drive shaft movement groove 10012'. At the upper end of 0012, the third drive shaft 421 is still located near the output main shaft 13, outputting a signal indicating that the entire switch is in the closed state. When the switch is in the state where both the first and second power supplies are open (i.e., in the double-open state), the first drive shaft 411 and the second drive shaft 412 are both located in the middle of the first drive shaft movement groove 10012 and the second drive shaft movement groove 10012', and the two drive shafts are at the same horizontal position. At this time, the third drive shaft 421 will be located away from the output main shaft 13, outputting a signal indicating that the entire switch 1 is in the open state. In summary, the closing / opening output drive mechanism 4 forms a crank-rocker mechanism.

[0114] like Figure 11 As shown, the position signal module 5 includes a first signal switch 51 and a second signal switch 52, both disposed around the camshaft 50, and a third signal switch 53 and a fourth signal switch 54, both disposed on the upper side of the camshaft 50. The first signal switch 51, the second signal switch 52, the third signal switch 53, and the fourth signal switch 54 are located on the same plane perpendicular to the X-axis.

[0115] like Figure 11 , Figure 13 As shown, the cam surface 501 of the camshaft 50 is used to drive the first micro switch 51 and the second micro switch 52, thereby outputting the first and second power on / off signals respectively. The top surface of the camshaft 50 is provided with a drive boss 502 and a cam drive groove 503. The drive boss 502 is provided with a screw mounting hole 504 at its center.

[0116] like Figures 11 to 13 As shown, the connecting shaft 414 located in the middle of the turntable 41 of the closing / opening output drive mechanism 4 cooperates with the cam drive groove 503. The connecting hole 415 of the turntable 41 cooperates with the drive boss 502. The screw 413 passes through the screw mounting hole 504 and is screwed into the top of the output main shaft 13 from the top surface of the drive boss 502, realizing the linkage of the output main shaft 13, cam shaft 50 and turntable 41 of the operating mechanism 1. The connecting rod 42 can also be two, which can be hinged to the first drive shaft 411 and the second drive shaft 412 respectively to realize two sets of rocker arm slider structures, thereby meeting the needs of multiple interlocking.

[0117] like Figure 4 , Figure 5 , Figure 6 , Figure 10 As shown, the push rod assemblies 32 in the two sets of stop assemblies 3 are distributed on both sides of the output main shaft 13 and are symmetrically arranged, respectively corresponding to the first spring mechanism and the second spring mechanism. The closing and opening output drive end 3214 of the push rod 321 on the side corresponding to the first spring mechanism extends toward the first drive shaft 411 on the closing and opening output mechanism 4 and cooperates with the first drive shaft 411. The closing and opening output drive end 3214 of the push rod 321 on the side corresponding to the second spring mechanism extends toward the second drive shaft 412 on the closing and opening output mechanism 4 and cooperates with the second drive shaft 412. Thus, the closing and opening output drive ends 3214 of each pair of push rods 321 extend toward each other. In this application example, the push rod drive shaft 32131 on the push rod 321 passes through the right outer side plate 1002 via the drive shaft movement groove 10021. In addition to cooperating with the limiting member 2006 in the first application example, it will also cooperate with the interlocking plate 2007, which will be described below. The push rod return spring 322 acts on the first drive end 3212, causing the push rod assembly limiting shaft 10014 to abut against the first limiting wall 32111 of the push rod limiting groove 3211. The push rod assembly 32 is in the non-drive position. When the push rod 321 is driven by the closing and opening output drive mechanism 4 or the limiting member 2006, which will be described below, to overcome the action of the push rod return spring 322 and cause the push rod assembly limiting shaft 10014 to abut against the second limiting wall 32112 of the push rod limiting groove 3211, the push rod assembly 32 is in the drive position.

[0118] like Figure 23 As shown, on the drawer seat side plate 2003 of the drawer seat 200 with the upper switch, a pair of interlocking plates 2007 are rotatably arranged at the position corresponding to the right inner side plate 1001 of the upper switch. Each interlocking plate 2007 corresponds to the first spring mechanism and the second spring mechanism of the upper switch. The two interlocking plates 2007 have the same structure and are symmetrically arranged on both sides of a pair of guide rails 2004. Similarly, on the drawer seat side plate 2003 of the drawer seat 200 with the lower switch, a pair of interlocking plates 2007 are rotatably arranged at the position corresponding to the right inner side plate 1001 of the lower switch. Each interlocking plate 2007 corresponds to the first spring mechanism and the second spring mechanism of the lower switch. The two interlocking plates 2007 have the same structure and are symmetrically arranged on both sides of a pair of guide rails 2004. The interlocking plate 2007 of the first spring mechanism corresponding to the upper switch is connected to the interlocking plate 2007 of the first spring mechanism corresponding to the lower switch via an interlocking lever 2008. Similarly, the interlocking plate 2007 of the second spring mechanism corresponding to the upper switch is connected to the interlocking plate 2007 of the second spring mechanism corresponding to the lower switch via an interlocking lever 2008. The two interlocking levers 2008 are arranged in parallel.

[0119] like Figure 3 , Figure 10 , Figure 22 As shown, during the process of the switch 100 being rocked into the drawer seat, as the switch 100 moves from the disengaged, test, to the connected position, the push rod drive shaft 32131 on the push rod 321 engages with different end faces on the limiting member 2006. When the switch 100 reaches the connected position, the push rod drive shaft 32131 also engages with the interlocking plate 2007. Therefore, the limiting member 2006 is positioned relative to the interlocking plate 2007 on the outside of the drawer seat 200, that is, near the entrance of the switch to and from the drawer seat 200.

[0120] like Figure 24 , Figure 25a , Figure 25b As shown, the surface of the limiting member 2006 facing the guide rail 2004 is formed with an inlet section, a separation test section, a test connection section, and a connection section. A limiting member positioning boss 20067 protrudes from the surface of the drawer seat side plate 2003 facing the drawer seat 100, and an opening groove 20068 is provided on the surface facing the interlocking plate 2007. The limiting member 2006 is positioned on the limiting member positioning hole 20031 on the drawer seat side plate 2003 of the drawer seat 200 by the limiting member positioning boss 20067, and is fixed by screws passing through the mounting hole 20032 on the drawer seat side plate 2003 and screwed into the nut recessed inside the limiting member 2006. The opening groove 20068 is located in the middle of the limiting member 2006 along its thickness direction to accommodate the interlocking plate 2007.

[0121] like Figure 22 , Figure 24 , Figure 26a , Figure 26bAs shown, the interlocking plate 2007 is pivotally connected inside the drawer seat side plate 2003. It includes an interlocking plate drive end 20072 and an interlocking end 20073 respectively located at both ends of the pivoting center hole 20071. The interlocking plate drive end 20072 is disposed within the opening slot 20068 of the limiting member 2006 and includes a guide surface 200721, a closing drive surface 200722, and a opening drive surface 200723. The guide surface 200721 ​​should be able to cause the interlocking plate 2007 to rotate around the pivoting center hole 20071 when subjected to force. The interlocking end 20073 is provided with an interlocking boss 200731. The interlocking boss 200731 passes through the drawer seat side plate 2003 and faces the outside of the drawer seat 200. The drawer seat side plate 2003 is provided with a corresponding movement groove 20033 for the interlocking boss 200731 to move. The end of the interlocking boss 200731 that extends out of the drawer seat side plate 2003 is connected to the interlocking lever 2008. A return spring 20075 is also provided between the interlocking plate 2007 and the drawer seat side plate 2003 of the drawer seat 200. The middle part of the return spring 20075 is sleeved on the pivot shaft 20074 of the interlocking plate 2007, and one end abuts against the interlocking boss 200731, and the other end abuts against the limiting member 2006. Under the action of the return spring 20075, the guide surface 200721 ​​of the interlocking plate 2007 abuts against the test connection section 20063 on the limiting member 2006. Figure 23 In a bypass-type switchgear, when the upper switch (bypass switch) is closed, its closing / opening output drive mechanism 4 drives the push rod 321. Through the interlocking plate 2007 corresponding to the upper switch and the interlocking lever 2008, when the lower switch (automatic transfer switch) is pushed into its corresponding drawer seat, the opening drive surface 200723 on the interlocking plate 2007 of the lower switch is flush with the test connection section 20063 on the limiting member 2006. Figure 27d As shown in the image.

[0122] When switch 100 is cranked into drawer seat 200, the drive shaft 32131 on push rod 321 corresponding to the first spring mechanism and the second spring mechanism slides along the separation test section 20062 on the limiting member 2006 (e.g., Figure 27a When push rod 321 reaches transition section 20065, push rod 321 is lifted under the action of transition section 20065, causing push rod assembly 32 of the first spring mechanism on switch 100 to rotate counterclockwise and push rod assembly 32 of the second spring mechanism to rotate clockwise. (Reference) Figure 5The position of the spring mechanism, thereby causing the interlocking boss 31221 on the corresponding rocker arm 312 of the spring mechanism in the closed ready position to begin moving downwards towards the limiting boss 121 of the corresponding latch 12. For the spring mechanism in the non-closed ready position, since the rocker arm assembly 31 of the spring mechanism on this side is in the inner disengagement position outside the movement trajectory of the latch 12 under the action of the closing lever 11 on this side, the movement of the push rod assembly 32 on this side does not interfere with the rocker arm assembly 31 on this side. When the push rod drive shaft 32131 moves above the test section 20063 (e.g. Figure 27b The interlocking bosses 31221 on the two levers 312 of switch 100 are directly below the limiting bosses 121 of latches 12, and both latches 12 on operating mechanism 1 are locked, so switch 100 cannot be closed. When switch 100 continues to move, push rod drive shaft 32131 begins to contact the guide surface 200721 ​​on interlock plate 2007 (e.g., Figure 27c This causes the interlocking plate 2007 to rotate under the force of its own reset spring until the push rod drive shaft 32131 moves onto the tripping drive surface 200723 (as shown). Figure 27d When switch 100 continues to move to transition section 20066, a pair of push rod assemblies 32 and a pair of rocker arm assemblies 31 on switch 100 reset under the action of their respective spring forces, driving the push rod drive shaft 32131 to move to connecting section 20064 (e.g., Figure 27e At this time, the latch 12 on switch 100 is unlocked, and the closing and opening operations can be performed.

[0123] like Figure 10 , Figure 26a , Figure 26b As shown, when the switch 100 is closed or opened, the push rod drive shaft 32131 on the push rod 321 corresponding to the first spring mechanism and the push rod drive shaft 32131 on the push rod 321 corresponding to the second spring mechanism cooperate with the drive groove 200724 on the interlocking plate 2007 between the closing drive surface 200722 and the opening drive surface 200723, thereby driving the interlocking plate 2007 to move accordingly, and outputting an interlocking signal through the interlocking boss 200731 on the interlocking plate 2007.

[0124] like Figure 22 , Figure 24 As shown, the guide rail 2004, the limiting member 2006, the interlocking plate 2007 and the gear guide plate 20021 of the gear transmission assembly 2002 are interlocked with each other, and from the inside to the outside they are the gear guide plate 20021, the interlocking plate 2007, the limiting member 2006 and the guide rail 2004.

[0125] like Figure 28a , Figure 28bAs shown, when the first power supply of the upper switch is closed and the second power supply is open, the closing / opening lever 11 in the first spring mechanism of the upper switch is in the lower ready position, releasing the push of the drive spring 313 of the corresponding rocker arm assembly 31 of the first spring mechanism. The rocker arm assembly 31 is in the outward disengagement position outside the action trajectory of the latch 12 in the first spring mechanism, as shown. Figure 28b The left-side rocker arm assembly 31 is shown in the position. The closing / opening lever 11 in the second spring mechanism is in the upper, non-ready position, pushing the drive spring 313 of the corresponding rocker arm assembly 31 of the second spring mechanism. This side rocker arm assembly 31 is in the inner disengaged position outside the movement trajectory of the latch 12 in the second spring mechanism, as shown. Figure 28b At the position shown by the right-side lever assembly 31, the first drive shaft 411 of the opening and closing output drive mechanism 4, which moves with the output main shaft 13, releases pressure on the push rod assembly 32 corresponding to the first spring mechanism. This push rod assembly 32 is in the non-drive position. The second drive shaft 412 pushes the push rod assembly 32 corresponding to the second spring mechanism, and this push rod assembly 32 is in the drive position. At this time, when the lower switch is in the first power open position and the second power open position (i.e., double open position) and the second spring mechanism is in the closing ready state, in this state, touching the latch 12 of the second spring mechanism will cause the second spring mechanism to release energy, drive the output main shaft 13 of the operating mechanism 1 to rotate, and cause the moving contact to close with the second stationary contact to realize the second power close. The opening and closing lever 11 in the first spring mechanism is in the upper non-ready position, that is, the first spring mechanism is not ready. Therefore, even if the latch 12 of the first spring mechanism is triggered, the first spring mechanism cannot be activated. In this state, when the closing / opening lever 11 in the second spring mechanism of the lower switch is in the lower ready position and releases the push on the corresponding rocker arm assembly 31 of the second spring mechanism, the rocker arm assembly 31 is in the outward disengagement position outside the action trajectory of the latch 12 in the second spring mechanism. Since the lower switch is in the double open position, the first drive shaft 411 and the second drive shaft 412 of its closing / opening output drive mechanism 4 have no pushing effect on the pair of push rod assemblies 32, and the push rod assemblies 32 are both in the non-drive position. Figure 29a As shown; however, since the push rod assembly 32 corresponding to the second spring mechanism of the upper switch is in the driving position, the push rod drive shaft 32131 on its push rod 321 will push the corresponding interlocking plate 2007 to move to Figure 27f At the position shown, due to the transmission of the upper interlocking plate 2007 and the interlocking lever 2008, the two sets of push rod assemblies 32 of the lower switch will move to the same position as the two push rod assemblies 32 of the upper switch. At this time, the push rod 321 corresponding to the first spring mechanism of the lower switch will not move, while the push rod 321 corresponding to the second spring mechanism of the lower switch will move to the driving position, thereby pushing the side rocker arm assembly 31 to the stop position within the movement trajectory of the latch 12 by the push rod assembly 32 on this side. Figure 30At the position shown in the right-side lever assembly 31, the stop latch 12 is activated to prevent the second power supply of the lower switch from closing.

[0126] like Figure 29b As shown, when the lower switch is in the double-open position (first power supply open and second power supply open) and the second spring mechanism is in the closing ready state, if at this time, the upper switch completes closing and reaches the second power supply closed position, as follows: Figure 31a , Figure 31b As shown, in this state, since the first drive shaft 411 in the closing and opening output drive mechanism 4 is located at the upper end of the first drive shaft movement groove 10012 of the right inner side plate 1001, the first drive shaft 411 pushes the closing and opening output drive end 3214 of the push rod 321, causing the push rod 321 on the first spring mechanism side to be in the drive position. However, since the closing and opening lever 11 in the first spring mechanism is in the upper non-ready position, it pushes the drive end 3131 on the drive spring 313 on the swing rod assembly 31, causing the swing rod 312 to be in the inner disengagement position. At this time, the push rod 321 is in the drive position or the non-drive position and does not interfere with the swing rod 312. The second drive shaft 412 in the closing / opening output drive mechanism 4 is located at the lower end of the second drive shaft movement groove 10012' of the right inner side plate 1001. The second drive shaft 412 does not push the push rod 321, causing the push rod 321 on the second spring mechanism side to be in a non-drive position. Since the closing / opening lever 11 in the second spring mechanism is in the lower ready position, it does not push the drive end 3131 on the drive spring 313 of the rocker arm assembly 31, causing the rocker arm 312 on this side to be in the outward disengagement position under the action of the reset spring. Figure 31b The position of the rocker arm assembly 31 on the right side is shown. The action of the pair of push rods 321 of the upper switch 100 is transmitted to the pair of push rods 321 of the lower switch 100 through the interlocking plate 2007 and the interlocking lever 2008, so that the pair of push rods 321 of the lower switch 100 have the same position: the push rod 321 on the first spring mechanism side is in the driving position, and the push rod 321 on the second spring mechanism side is in the non-driving position. Since the upper switch is in the double-open and the second spring mechanism is in the closed ready position at this time, in this position, the opening / closing lever 11 in the first spring mechanism is in the upper non-ready position. When the push rod 321 on that side is in the inner disengaged position, even if the push rod 321 on that side is forced to rotate counterclockwise to the drive position due to the interlock, it will not push the push rod 312 on that side. This keeps the push rods 312 on both sides in their original disengaged positions, allowing the latch 12 in the second spring mechanism to be triggered, causing the second spring mechanism to move and drive the switch to the second power supply closing position. Thus, the function of allowing the power supply on the same side of the two switches 100 to close simultaneously, but prohibiting the power supply on the opposite side from closing simultaneously, is realized in the bypass type switch.

[0127] like Figure 4 , Figure 5 , Figure 18 As shown, the right outer side plate 1002 and the right inner side plate 1001 are fixedly connected by the cooperation between the right outer side plate mounting positioning boss 10018 on the right inner side plate 1001 and the right outer side plate positioning hole 10026 on the right outer side plate 1002, and the right outer side plate positioning groove 10027 on the right outer side plate 1002 and the right outer side plate positioning boss 10019 on the right inner side plate 1001. A stop assembly 3 and an electrical interlocking signal switch module 6 are provided between the right outer side plate 1002 and the right inner side plate 1001.

[0128] like Figures 4 to 6 As shown, the electrical interlocking signal switch module 6 includes a first closing ready signal switch 60, a second closing ready signal switch (optional), a first closing signal switch 61, a second closing signal switch 62, a first auxiliary signal switch 63, and a second auxiliary signal switch 64, symmetrically arranged on both sides of the rotation center of the turntable 41, and directly driven by the outer surfaces of the first drive shaft 411 and the second drive shaft 412 of the turntable 41. The first closing signal switch 61 and the first auxiliary signal switch 63 are stacked together, and the second closing signal switch 62 and the second auxiliary signal switch 64 are stacked together. Each closing signal switch and each auxiliary signal switch is mounted on a signal mounting plate 69. Figure 5 From a visual perspective, the first closing signal switch 61 and the second closing signal switch 62 are respectively located on both sides below the rotation center of the turntable 41. The first closing signal switch 61 and the first auxiliary signal switch 63 are driven by the first drive shaft 411, and the second closing signal switch 62 and the second auxiliary signal switch 64 are driven by the second drive shaft 412. The signal lines 65 on the first closing ready signal switch 60, the second closing ready signal switch, the first closing signal switch 61, the second closing signal switch 62, the first auxiliary signal switch 63, and the second auxiliary signal switch 64 are connected to the contact group 67 on the back of the operating mechanism 1 through the outlet hole 66 on the right inner side plate 1001. Figure 1c The contact group 67 is fixed to the right inner side plate 1001 by the contact group fixing post 68 on the right inner side plate 1001, as shown below. Figure 7 As shown.

[0129] like Figure 1c , Figure 2 As shown, a contact group 67 is also provided on the back of the switch 100. The contact group 67 is installed on the back of the right inner side plate 1001 and is floated with the inner and outer side plates 1001.

[0130] The switch of the present invention is not limited to the above-mentioned applications, but can also be applied to a bypass type switch device in which the upper switch is fixed and the lower switch is withdrawable. When the upper switch is fixed, the upper switch does not need to be provided with a drawer seat and can be directly fixed on the left side plate 301 and the right side plate 302. When the lower switch is withdrawable, the lower switch can be rocked in and out of the drawer seat, and the drawer seat is fixed on the left and right side plates.
