Description

Technical Field

[0001] The present application relates to an isolating switch, which is applied in a power supply system. Background Art

[0002] Magnetic trip units are often used within control switches in circuit breakers, disconnectors, and other circuit breakers to trip these switches. The specific tripping process involves the magnetic trip unit communicating with a controller (either internal to the control switch or from a host computer). The controller sends a trip signal to the magnetic trip unit, triggering the magnetic trip unit to trip the control switch's operating mechanism.

[0003] This type of magnetic release cannot reset itself after being actuated and must be reset by external force. For example, a common method in the field is to use an operating mechanism to push the actuated magnetic release to reset during the re-engagement operation.

[0004] However, this reset method cannot meet some specific requirements. For example, in some cases, after tripping, the magnetic release can be reset without relying on the operating mechanism.

[0005] Therefore, how to improve the reset structure of the magnetic release has become a question worth considering. Summary of the Invention

Example

[0046] like Figure 1-16 As shown, the embodiment of the present application is a magnetic release module, including: a fixing plate 100, a reset button 200 and a release 300.

[0047] The reset button 200 and the trip unit 300 are both arranged on the fixing plate 100 , forming a module as a whole. The module can be installed in other switches (such as an isolating switch) through the fixing plate 100 .

[0048] The trip unit 300 is fixed to the fixing plate 100 by screw fastening. Of course, the fastening method is not limited to screws, and other methods such as snap-fitting and plug-in can also be used.

[0049] The fixing plate 100 includes a base plate 101, a first wall plate 102, a second wall plate 103, a third wall plate 104, and a fourth wall plate 105. The first, second, third, and fourth wall plates 102, 103, 104, and 105 are arranged around the perimeter of the base plate 101. The base plate 101 has a first surface M1 and a second surface M2. The first, second, third, and fourth wall plates 102, 103, 104, and 105 surround the first surface M1 to form an installation space. The first and second wall plates 102, 103 are spaced apart, with the third and fourth wall plates 104, 105 located between the first and second wall plates 102, 103. The trip unit 300 is fastened to the fourth wall plate 105 with screws, and is located near the second wall plate 103.

[0050] The trip unit 300 receives the trip signal via an interface 301. The opening of the interface 301 is located on the first wall panel 102. Specifically, the first wall panel 102 is connected to the third wall panel 104, and both of them define a mounting slot 106. The interface 301 is disposed within the mounting slot 106. The interface 301 can be secured in various ways, such as by directly screwing it to the fixing plate 100; by using a hook to secure the interface 301; or, after being installed in the mounting slot 106, by using a cover 110 to limit the position of the interface 301.

[0051] In this embodiment, a cover plate 110 is used to position the interface 301. In this manner, the cover plate 110 is fixed above the third wall plate 104, thereby securing the interface 301 within the mounting slot 106. Here, the cover plate 110 is secured to the fixing plate 100 using screws. In addition to screws, other methods such as snap-fitting and interference fit can also be used, as long as the cover plate 110 and the fixing plate 100 can be removably secured. In addition to limiting the position of the interface 301, the cover plate 110 also serves to shield the leads.

[0052] Limiting ribs 107 are located above the third wall 104. The gap between these limiting ribs 107 and the third wall 104 forms part of the wiring channel 108. The leads between the release 300 and the interface 301 pass through the wiring channel 108 and connect to the circuit board of the interface 301. The cover 110, when secured, shields the leads in the wiring channel 108. Of course, the interface 301 here includes not only interfaces with circuit boards, but also interfaces without circuit boards, such as interfaces 301 where only a connector is connected to the release 300 via leads.

[0053] The reset button 200 is movably mounted on the fixing plate 100. The reset button 200 is associated with the actuator 302 of the trip unit 300. When a user operates the reset button 200, the actuator 302 is restored from the actuation position S1 to the reset position S2.

[0054] The reset button 200 is at least partially exposed from the second surface M2 for user operation. Alternatively, a raised portion 109 may be provided on the second surface M2, with the reset button 200 at least partially exposed from the raised portion 109. Such a raised portion 109 can provide sufficient installation space for relatively complex and larger reset buttons 200.

[0055] The surface of the reset button 200 (the surface exposed on the second surface M2 ) is also provided with anti-slip textures and a handle, which helps the user to better operate the reset button 200 .

[0056] Of course, to help users understand the function or reset direction of the reset button 200, a reset mark M3 is provided on the reset button 200. In this embodiment, the reset mark M3 is a combination of graphics and text. The graphics indicate the direction (the graphics can be arrows, triangles, hand gestures, and other icons indicating directions), and the text can be Chinese characters or letters. Of course, the reset mark M3 can also be just graphics or text.

[0057] In addition, the reset mark M3 can also be disposed on the second surface M2 of the fixing plate 100 , as long as it is disposed close to the reset button 200 .

[0058] To help users understand that the reset button 200 is for the trip unit 300, a trip unit identifier M4 is provided on the reset button 200. In this embodiment, the trip unit identifier M4 is text, which can be in Chinese or alphabetic. Alternatively, the reset identifier M3 can be a graphic.

[0059] In addition, the trip unit mark M4 can also be set on the housing 501 as long as it is set close to the reset button 200.

[0060] A preferred method for the reset indicator M3 and the trip unit indicator M4 is to move along with the actuator 302 of the trip unit 300. That is, the reset button 200 and the actuator 302 of the trip unit 300 are configured to move synchronously. In this way, after the trip unit 300 is actuated, the reset indicator M3 is exposed, while the trip unit indicator M4 is hidden within the fixing plate 100, allowing the user to know how to reset the trip unit 300. After the trip unit 300 is reset, the reset indicator M3 is hidden within the fixing plate 100, while the trip unit indicator M4 is exposed, allowing the user to know that the corresponding component within this component is the trip unit 300.

[0061] The release 300 is a magnetic flux release 300 , and its actuator 302 has an actuation position S1 and a reset position S2 . After each actuation (when the actuator 302 reaches the actuation position S1 ), an external force is required to drive the actuator 302 to reset the release 300 (when the actuator 302 returns to the reset position S2 ).

[0062] Of course, in addition to the flux release 300, the release 300 may also adopt other forms of magnetic release 300, as long as it can meet the principle of using an electromagnet, actuated after receiving a trip signal, and will not reset naturally (self-reset), and can only be reset under the action of an external force.

[0063] Here, the actuator 302 is a push rod 302', which is linked to the movable iron core 303 (hereinafter referred to as the movable iron core 303 for clarity) within the magnetic flux release 300. Specifically, when the release 300 is energized, the movable iron core 303 within the release moves, causing the push rod 302' to move, thereby causing the re-engagement 505b to move. The push rod 302' and the movable iron core 303 can move in the same manner, for example, both in a linear sliding configuration or a rotational configuration. When the movable iron core 303 moves, the push rod 302' also moves synchronously.

[0064] Of course, the movement modes of the push rod 302' and the movable iron core 303 can also be different. For example, the movable iron core 303 can be configured to slide linearly, while the push rod 302' can be configured to rotate, forming a linkage between the two (there are many linkage methods, such as abutment, hinge, etc.). During actuation, the sliding of the movable iron core 303 is converted into the rotation of the push rod 302'; during reset, the rotation of the push rod 302' is converted into the sliding of the movable iron core 303. Of course, the movement modes here can also be reversed, that is, the movable iron core 303 can be configured to rotate and the push rod 302' can be configured to slide linearly.

[0065] Of course, as an alternative, the actuator 302 is a moving iron core 303, that is, there is no additional push rod 302'. After the release 300 is energized, the movement of the moving iron core 303 directly causes the re-lock 505b to move (here, the re-lock 505b is pushed to rotate, and it can also be pulled to rotate).

[0066] The reset button 200 and the actuator 302 of the trip unit 300 can move in various ways, including sliding along a straight line or rotating.

[0067] As an implementation method, Figure 1-5 As shown, the reset button 200 and the actuator 302 of the trip unit 300 are both arranged to slide along a straight line. In this case, the reset button 200 and the actuator 302 of the trip unit 300 are arranged to move synchronously. In this embodiment, the reset button 200 and the actuator 302 of the trip unit 300 are integrally formed, so they can achieve synchronous movement. Of course, the reset button 200 and the actuator 302 of the trip unit 300 can also be two independently formed components, fixed together by screw fastening, interference fit, plug-in connection, riveting, etc. to achieve synchronous movement.

[0068] As a variation of this embodiment, the reset button 200 and the trip unit 300 can both be rotatable. The reset button 200 and the actuator 302 of the trip unit 300 can be integrally formed; alternatively, the reset button 200 and the actuator 302 of the trip unit 300 can be separate components that are secured together by screws, an interference fit, a plug-in connection, or riveting to achieve synchronized movement.

[0069] As another embodiment, Figure 6 As shown, the reset button 200 rotates, while the actuator 302 of the trip unit 300 slides along a straight line. The reset button 200 and the actuator 302 of the trip unit 300 are linked. Here, the reset button 200 and the actuator 302 of the trip unit 300 form a slider crank mechanism. When the actuator 302 of the trip unit 300 slides, it drives the reset button 200 to rotate; and when the reset button 200 rotates, it also drives the actuator 302 of the trip unit 300 to slide.

[0070] In this manner, since the reset button 200 moves in a rotational manner, it occupies relatively little space, which is a more ideal choice in situations where the structural space or operating space is limited.

[0071] As a variation of this approach, the actuator 302 of the trip unit 300 can also be configured to rotate, while the reset button 200 can be configured to slide along a straight line, creating a linkage between the two. In this arrangement, when the actuator 302 of the trip unit 300 rotates, it can cause the reset button 200 to slide; and when the reset button 200 slides, it can also cause the actuator 302 of the trip unit 300 to rotate.

[0072] As another embodiment, Figure 7-8 As shown, the reset button 200 and the actuator 302 of the trip unit 300 move in the same manner, but they do not move completely synchronously. The actuator 302 is located on one side of the reset button 200. In this configuration, a reset spring 201 is also provided. Each time the reset button 200 resets the first actuator 302 of the trip unit 300, the reset button 200 returns to its original position under the action of the reset spring 201. Specifically, the reset button 200 has a first position F1 and a second position. The reset button 200 slides along a straight line. When the reset button 200 moves from the first position F1 to the second position under the action of an external force, it moves against the actuator 302, driving the actuator 302 of the trip unit 300 (the actuator 302 of the trip unit 300 after activation) to return to the reset position S2. At the same time, the reset spring 201 is compressed. After the external force disappears, the reset spring 201 drives the reset button 200 back to the first position F1.

[0073] As a modified implementation of this method, the movement forms of the reset button 200 and the actuating member 302 of the tripper 300 may also be set to rotation.

[0074] The reset button 200 with the reset spring 201 can ensure that the reset button 200 is in the same position after each movement.

[0075] As an application in a switch, the magnetic release module is installed in an isolating switch, which includes a contact module 400 and an operating module 500 .

[0076] The contact modules 400 are stacked in 12 layers below the operating module 500. The number of layers of contact modules 400 is determined based on the number of control circuits required and is not limited to a single-layer structure. In addition to this configuration where all contact modules are stacked below the operating module 500, the contact modules 400 can also be located on both sides of the operating module 500.

[0077] The contact module 400 includes a housing, a movable contact disc 401, a movable contact 402, and a stationary contact 403. The movable contact disc 401 is rotatable, and the movable contact 402 is mounted on the movable contact disc 401. Rotation of the movable contact disc 401 connects and disconnects the movable contact 402 with the stationary contact 403.

[0078] Here, the force required for the rotation of the movable contact disk 401 comes from the operating mechanism 503. Specifically, the movable contact disks 401 of each contact module 400 are plugged in one by one, and the movable contact disk 401 closest to the operating mechanism 503 is plugged in with the output disk of the operating mechanism 503. In this way, the output force of the operating mechanism 503 can be transmitted to each movable contact disk 401, thereby causing the movable contact 402 to rotate and contact and separate with the static contact 403, that is, achieving the effect of "the movable contact 402 is in contact with and separated from the static contact 403 under the action of the operating mechanism 503".

[0079] Here, the movable contact 402 and the stationary contact 403 can form either a single-breakpoint structure or a dual-breakpoint structure. In a single-breakpoint structure, each contact module 400 has only one stationary contact 403 and one movable contact 402. In a dual-breakpoint structure, each contact module 400 has two stationary contacts 403 and one movable contact 402. During rotation, one movable contact 402 simultaneously contacts or separates from both stationary contacts 403.

[0080] Here, the movable contact 402 and the stationary contact 403 can be in various contact configurations, including a snap-fit ​​configuration and a clamping configuration. In a snap-fit ​​configuration, the movable contact 402 and the stationary contact 403 are in contact with each other. In a clamping configuration, one of the movable contact 402 and the stationary contact 403 clamps the other. There are various clamping configurations, including two springs and two contact blades, two conductive springs, or a single contact blade and a single spring.

[0081] As a clamping structure, the movable contact 402 includes a first contact blade 402a and a first spring piece 402b. The first contact blade 402a and the first spring piece 402b are riveted together, forming a clamping opening between the ends of the first contact blade 402a and the first spring piece 402b. As the movable contact 402 rotates, the stationary contact 403 extends into the clamping opening, where the first spring piece 402b deforms to provide clamping force for the stationary contact 403. The first contact blade 402a serves as the primary flow passage.

[0082] The operating module 500 includes a housing 501 , a handle 502 , an operating mechanism 503 and a magnetic release 300 module.

[0083] The operating mechanism 503 includes an input shaft 504 , a frame, an energy storage mechanism and a locking assembly 505 .

[0084] The handle 502 is located above the upper surface of the housing 501 ; the handle 502 is connected to the input shaft 504 for user manipulation.

[0085] The energy storage mechanism is a multi-link structure with a spring, including a lever, a main tension spring, a jump buckle, an upper link, a lower link and an output member.

[0086] The lever and the frame are set to swing, and the input shaft 504 is connected to the lever through a conversion structure. The conversion structure here can adopt either gear transmission or connecting rod transmission, as long as it can convert the rotation of the input shaft 504 into the swing of the lever.

[0087] The jumper is rotatably mounted relative to the frame, the upper connecting rod is rotatably mounted on the jumper, the lower connecting rod is hinged to the upper connecting rod, and the output member is rotatably mounted on the lower connecting rod, the output member being adapted to engage with the output disk. The two ends of the main tension spring are respectively connected to the hinge shafts connecting the lever and the upper and lower connecting rods.

[0088] The locking assembly 505 includes a locking buckle 505a and a locking buckle 505b.

[0089] When the disconnector is in the closed state, the main tension spring is in a deformed state, the lock buckle 505a and the re-lock buckle 505b are in a locked state, and the trip buckle is also maintained in the current position (that is, the lock buckle 505a and the trip buckle are overlapped or overlapped, and the re-lock buckle 505b and the lock buckle 505a are overlapped or abutted), so that the energy storage mechanism is in a steady state.

[0090] When the locks of the lock catch 505a and the re-lock catch 505b are released (because the trip unit 300 is actuated to rotate the re-lock catch 505b), the steady state of the energy storage mechanism is broken, and under the action of the main tension spring, the operating mechanism 503 performs a tripping operation.

[0091] The working principle of this operating mechanism 503 has been described in detail in CN219321237U previously applied for by the applicant, and will not be repeated here.

[0092] The housing 501 includes a trip chamber 501a and an operating mechanism chamber 501b. The trip chamber 501a is located on one side of the operating mechanism chamber 501b. The operating mechanism 503 is disposed in the operating mechanism chamber 501b, and the trip 300 is disposed in the trip chamber 501a.

[0093] The housing 501 includes a base 5010, a cover 5011, and a fixing plate 100. The sidewalls of the base 5010 have a notch 5012, which the fixing plate 100 fits into. The fixing plate 100 is removably secured to the base 5010. The removable fastening employed herein is specifically screw fastening, although alternatives include snap fastening, snap fastening, and screw fastening. By installing the fixing plate 100, the release 300 can be installed within the release chamber 501a.

[0094] The cover 5011 is fixed to the base 5010 to close the opening of the base 5010 (the opening is connected to the operating mechanism chamber 501b and is used to install the operating mechanism 503). The cover 5011 and the base 5010 are fixed here by screws, but riveting, snap fastening, etc. can also be used.

[0095] When used in an inverter, only the handle 502 of this disconnect switch is exposed. If the trip unit 300 receives a trip signal from the controller, it actuates, unlocking the latch assembly 505 and causing the operating mechanism 503 to trip. After the trip unit 300 is actuated, the actuator 302 of the trip unit 300 prevents the latch assembly 505 from resetting. The user can only close the disconnect switch after resetting the trip unit 300.

[0096] It can be used in situations where a serious fault occurs in the inverter (where the inverter box must be opened for inspection and reset), effectively preventing the user from mistakenly closing the isolation switch without performing an unpacking inspection.

[0097] Of course, in addition to the above-mentioned magnetic release 300 module, an additional release 300 may be provided on the fixing plate 100 , and the reset of the release 300 may be associated with the operating mechanism 503 of the switch.
