Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinet control switches, and in particular to a power distribution cabinet control switch and a power distribution cabinet. Background Art

[0002] Control switches in distribution cabinets are core components used to control, protect, isolate, and monitor electrical equipment in power distribution systems. Through manual or automatic operation, they manage the connection and disconnection of circuits, ensuring the safe, stable, and efficient operation of the power system. Control switches play a critical role in distribution cabinets, not only distributing electrical energy but also providing protection in the event of a fault, preventing equipment damage or accidents.

[0003] At present, when workers operate the control switches in existing distribution cabinets, it is easy for them to forget the steps of operating the control switches. For example, when turning off the main switch, they need to disconnect the load switch first and then disconnect the main switch. However, long hours of work may cause workers to relax their vigilance, and it is easy for them to forget to disconnect the load switch and disconnect the main switch, which poses a great safety hazard.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing distribution cabinet control switches and distribution cabinets on the market.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Example 1: Please refer to Figure 1 、 Figure 2 、 Figure 4-Figure 8 and Figure 13 The present invention provides a technical solution: a power distribution cabinet control switch and a power distribution cabinet, comprising a main control switch 1, a switch sequence limiting mechanism 2 is provided on the outside of the main control switch 1, and a short circuit measuring mechanism 3 is provided on the outside of the main control switch 1;

[0039] The switch sequence limiting mechanism 2 is used to limit the closing sequence of the main control switch 1 and the load control switch 204 .

[0040] As a further limitation of the switch sequence limiting mechanism 2 of the present invention, the switch sequence limiting mechanism 2 includes a load control switch 204 and a first rectangular frame 206. The inner walls of the load control switch 204 and the main control switch 1 are rotatably connected to a gate 207. The back of the gate 207 is fixedly connected to a moving block 217. The interior of the first rectangular frame 206 is slidably connected to a first slider 201 and a second slider 208. The left sides of the first slider 201 and the second slider 208 are fixedly connected to two rectangular plates 205. The right side of the first slider 201 is fixedly connected to a card block 219. The left side of the first slider 201 is fixedly connected to an extrusion block 218. The top of the second slider 208 is fixedly connected to a limiting axis 214. The rear of the first rectangular frame 206 is provided with A second rectangular frame 202 is provided with a first force spring 212 inside the second rectangular frame 202, and the first force spring 212 is fixedly connected to a first limiting plate 215 at one end close to the first rectangular frame 206. A first circular cylinder 203 is provided behind the first rectangular frame 206, and a second force spring 213 is provided inside the first circular cylinder 203, and the second force spring 213 is fixedly connected to a second limiting plate 209 at one end close to the first rectangular frame 206; by setting up a switch sequence limiting mechanism 2, the switch sequence limiting mechanism 2 can ensure that when the staff operates the control switch inside the distribution cabinet 3211, they will not forget to close the load switch gate 207 and operate the main control switch 1, thereby avoiding the problem of fire or even explosion.

[0041] See also Figure 4 and Figure 5The upper and bottom surfaces of the first rectangular frame 206 are both provided with T-shaped slots 210, and the interior of the T-shaped slots 210 is slidably connected to a T-shaped slider 211, wherein the left side of one T-shaped slider 211 is fixedly connected to the right side of the first slider 201, and the left side of the other T-shaped slider 211 is fixedly connected to the right side of the second slider 208, and the outer surface of the first limiting plate 215 is slidably connected to the interior of the first rectangular frame 206, and the upper surface of the first limiting plate 215 is aligned with the bottom surface of the block 219. The outer surface of the limiting shaft 214 is slidably connected to the inside of the first limiting plate 215, the inner wall of the second limiting plate 209 is in contact with the outer surface of the extrusion block 218, and the outer surface of the second limiting plate 209 is slidably connected to the inside of the first rectangular frame 206; by providing a T-shaped slide 210 and a T-shaped slider 211, the first slider 201 and the second slider 208 can be limited by utilizing the characteristic of the T-shaped slider 211 sliding inside the T-shaped slide 210, so that the two can only move in the upper and lower positions.

[0042] See also Figure 6 The inner wall of the moving block 217 is rotatably connected to two rollers 216, and the outer surface of the roller 216 contacts the side of the rectangular plate 205 close to the moving block 217; by providing the roller 216, the friction between the moving block 217 and the rectangular plate 205 can be reduced by utilizing the roller 216.

[0043] The specific implementation of this embodiment is as follows: when the staff wants to operate the control switch inside the distribution cabinet 3211, they can only push the gate 207 on the load control switch 204 to rotate first. When the gate 207 of the main control switch 1 is rotated, the moving block 217 fixed on the back of the gate 207 will be used to push the rectangular plate 205 near the gate 207 connected to the main control switch 1 to move downward, and when the rectangular plate 205 moves, it will drive the first slider 201 to move downward as well. However, at this time, the block 219 fixed on the back of the first slider 201 contacts the first limiting plate 215, so the first limiting plate 215 will limit the block 219 from moving downward. Similarly, the first limiting plate 215 will limit the first slider 201 to prevent The first slider 201 moves downward, so the staff can only push the gate 207 on the load control switch 204 first. When the gate 207 on the load control switch 204 rotates, the two rectangular plates 205 fixed on the left side of the second slider 208 will also be driven downward by the moving block 217. When the rectangular plate 205 moves downward, it will push the second slider 208 and the limiting shaft 214 fixed on the upper surface of the second slider 208 to move downward, so that the limiting shaft 214 moves downward to the bottom of the first limiting plate 215, releasing the limit on the first limiting plate 215. At this time, the first limiting plate 215 will move backward under the action of the first force spring 212, so that the upper surface of the first limiting plate 215 will not be in contact with the bottom of the block 219. Therefore, it can be understood that when the limit shaft 214 is inside the first limit plate 215, the first force spring 212 will always be in a stretched state, and after the second slider 208 moves downward, the rectangular groove opened on the left side of the second slider 208 will just correspond to the second limit plate 209, but at this time the second limit plate 209 is in contact with the surface of the extrusion block 218. Therefore, although the second limit plate 209 is pushed by the second force spring 213, under the restriction of the extrusion block 218, the second limit plate 209 still cannot move to the rectangular groove opened on the left side of the second slider 208, and then the gate 207 on the main control switch 1 can be pushed to rotate. At this time, the gate 207 on the main control switch 1 can push the first slider. When the first slider 201 moves downward, the extrusion block 218 fixed on its left side moves downward. The extrusion block 218 gradually loses contact with the second limiting plate 209 during the downward movement. Therefore, the second limiting plate 209 enters the rectangular groove on the left side of the second slider 208 under the action of the second force spring 213, thereby limiting the second slider 208. This ensures that the staff must close the load control switch 204 before closing the main control switch 1. At this point, the gates 207 of the main control switch 1 and the load control switch 204 are all closed. At this time, the load control switch 204 is in a locked state, and the main control switch 1 can be opened freely. When power is needed,The gate 207 on the main control switch 1 can be pushed upward, and the gate 207 can push the first slider 201 upward. When the first slider 201 moves upward, it will use the inclined surface of the extrusion block 218 to push the second limiting plate 209 to squeeze the second force spring 213, thereby releasing the limit of the second slider 208. Only then can the gate 207 on the load control switch 204 be pushed to rotate, further pushing the second slider 208 to move upward, and the limiting shaft 214 fixed on the upper surface of the second slider 208 will pass through the circular hole on the surface of the first limiting plate 215 again, so that the first limiting plate 215 can be pulled forward again. At this time, the first limiting plate 215 will be under the block 219 again, thereby limiting the block 219 and the first slider 201 again, thereby achieving the purpose of closing the main control switch 1 first and then closing the load control switch 204 when power is supplied.

[0044] Example 2: Please refer to Figures 1-4 and Figures 9-11 The present invention provides a technical solution: a distribution cabinet control switch and a distribution cabinet. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The short-circuit measurement mechanism 3 includes a limiting unit 31. The limiting unit 31 is arranged on the outside of the main control switch 1. The limiting unit 31 can ensure that the staff can perform short-circuit testing on the line in sequence before closing the switch.

[0045] As a further limitation of the short-circuit determination mechanism 3 of the present invention, the limiting unit 31 includes two rotating shafts 3102, the outer surfaces of the two rotating shafts 3102 are rotatably connected to the inner walls of the main control switch 1 and the load control switch 204 respectively, the outer surface of the rotating shaft 3102 is fixedly connected to a turntable 3103, one side of the turntable 3103 is rotatably connected to two transmission plates 3104 through a rotating shaft, the inner wall of the transmission plate 3104 is rotatably connected to a lifting plate 3112, and a clamping hole 3116 is provided on the front of the lifting plate 3112, and the outer surfaces of the main control switch 1 and the load control switch 204 are fixedly connected to two third rectangular frames 3101, the interior of the third rectangular frame 3101 is slidably connected to the first long plate 3106, the front of the first long plate 3106 is fixedly connected to the clamping shaft 3108, the inner wall of the first long plate 3106 is fixedly connected to the second circular cylinder 3107, the inner wall of the second circular cylinder 3107 is fixedly connected to the third force spring 3114, the third force spring The right end of 3114 is fixedly connected to the first circular block 3115, the right side of the first long plate 3106 is fixedly connected to the movable plate 3111, the back of the movable plate 3111 is fixedly connected to the fourth force spring 3113, the side of the third rectangular frame 3101 away from the gate 207 is fixedly connected to the fixed plate 3110, and the side of the third rectangular frame 3101 away from the gate 207 is fixedly connected to the second long plate 3109; by setting the limiting unit 31, the limiting unit 31 can be used to ensure that the staff must test the connection status of the line before closing the gate 207 to prevent the line from having a short circuit problem without the staff knowing, thereby effectively avoiding the safety hazard such as fire caused by the short circuit phenomenon when the staff closes the switch and supplies power, the front of the fixed plate 3110 is fixedly connected to the end of the fourth force spring 3113 away from the movable plate 3111, and the left side of the second long plate 3109 contacts the right end of the first circular block 3115.

[0046] See also Figure 9 Two positioning cylinders 3105 are fixedly connected to the front of the main control switch 1 and the load control switch 204. The outer surface of each lifting plate 3112 is slidably connected to the inside of the corresponding positioning cylinder 3105. One side of the positioning cylinder 3105 is fixedly connected to one side of the third rectangular frame 3101. The outer surfaces of the two rotating shafts 3102 are respectively rotatably connected to the inner walls of the main control switch 1 and the load control switch 204. One end of the rotating shaft 3102 is fixedly connected to the front of the gate 207, and the end of the clamping shaft 3108 close to the lifting plate 3112 is in contact with the back of the lifting plate 3112. By providing the positioning cylinder 3105, the positioning cylinder 3105 can be used to limit the moving position of the lifting plate 3112.

[0047] The specific implementation of this embodiment is as follows: when the load control switch 204 and the main control switch 1 are closed, the gate 207 will drive the rotating shaft 3102 and the turntable 3103 to rotate, thereby pulling the two transmission plates 3104 and the lifting plate 3112 toward the middle until the card hole 3116 opened on the front of the lifting plate 3112 moves to the position corresponding to the card shaft 3108. At this time, the fourth force spring 3113 will push the first long plate 3106 and the card shaft 3108 to move forward until the card shaft 3108 is locked to the lifting plate In the card hole 3116 opened on the front of 3112, when the circuit inside the distribution cabinet 3211 is sorted out, the staff wants to directly close the gate 207 of the main control switch 1 but forgets to check whether the circuit has a short circuit problem. It will be found that the gate 207 cannot be rotated. Because the gate 207 is connected to the rotating shaft 3102, and the rotating shaft 3102 has a turntable 3103 on its surface, the gate 207 must drive the turntable 3103 to rotate. However, the rotation of the turntable 3103 will pull the two transmission plates 3104 and the lifting plate 3112. The lifting plate 3112 is limited by the clamping shaft 3108 and cannot be moved. Therefore, the staff must use a multimeter to check the connection of the circuit on the main control switch 1. When checking, the staff needs to use the multimeter plug to insert it into the circular through hole opened on the left side of the third rectangular frame 3101 one by one until the plug contacts the screw screwed into the main control switch 1. When the multimeter plug is inserted into the third rectangular frame 3101, the plug will push the first long plate 3106 to move backward, and the first long plate 3106 will move backward. When 106 moves backward, the third force spring 3114 will push the first circular block 3115 to insert into the space where the second circular block 3202 is located, thereby limiting the first long plate 3106, and the movement of the first long plate 3106 backward will drive the card shaft 3108 to disengage from the interior of the lifting plate 3112. At this time, the lifting plate 3112 will not be restricted, and will not be restricted when pushing the gate 207 to close the switch. This can ensure that the staff will check the connection status of the line before closing the switch.

[0048] Example 3: Please refer to Figures 1-4 and Figures 9-12 The present invention provides a technical solution: a distribution cabinet control switch and a distribution cabinet. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The short-circuit measurement mechanism 3 also includes a reset unit 32. The reset unit 32 is arranged on the outside of the main control switch 1. The reset unit 32 cooperates with the limiting unit 31, and the reset unit 32 can reset the limiting unit 31.

By setting a switch sequence limiting mechanism 2, a limiting unit 31 and a reset unit 32, it can effectively avoid the problem that the staff forgets the switch operation sequence and checks the line connection status before closing the switch due to negligence.

The inner wall of each movable door 3212 is fixedly connected to a transparent glass 3210, and the outer surface of each movable door 3212 is fixedly connected to a handle 3209. By providing the movable doors 3212 and the transparent glass 3210, the transparent glass 3210 can be used to conveniently observe the circuit conditions inside the distribution cabinet 3211.

[0051] See also Figure 2 Two filter plates 3214 are clamped inside the distribution cabinet 3211, and four short shafts 3215 are rotatably connected to the inner wall of the distribution cabinet 3211. The top of the short shaft 3215 is fixedly connected to a baffle 3213, and the bottom surface of the baffle 3213 is in contact with the upper surface of the filter plate 3214; by providing the filter plate 3214, the filter plate 3214 can prevent dust from entering the interior of the distribution cabinet 3211 along with the air, and the baffle 3213 can be rotated to the top of the filter plate 3214 under the action of the short shaft 3215 to limit the filter plate 3214.

[0052] See also Figure 2The inner wall of the distribution cabinet 3211 is fixedly connected with a connecting plate 3207, and the front of the connecting plate 3207 is rotatably hinged with a warning plate 3216. By providing the warning plate 3216 and utilizing the hinged relationship between the warning plate 3216 and the connecting plate 3207, the warning plate 3216 can be rotated ninety degrees. Combined with the warning text written on the front of the warning plate 3216, the problem of other people accidentally closing the switch to supply power when the staff is working on a power outage can be avoided.

[0053] The specific implementation of this embodiment is as follows: when the line connection status of the main control switch 1 and the load control switch 204 is detected, it means that the power is off at this time, and the lifting plate 3112 has also moved to the position of the turntable 3103. At this time, the card hole 3116 opened on the side of the lifting plate 3112 has also been in a card connection relationship with the card shaft 3108. At this time, the push plate 3205 is also under the extrusion plate 3204. Then, it is necessary to use the multimeter plug to insert it into the circular through hole opened on the left side of the third rectangular frame 3101 one by one. When the multimeter plug is inserted into the inside of the third rectangular frame 3101, the plug will push the first long plate 3106 to move backward, and the first When the long plate 3106 moves backward, the third force spring 3114 will push the first circular block 3115 to insert into the space where the second circular block 3202 is located, and the first circular block 3115 will push the second circular block 3202 to move to the right, and the second circular block 3202 will push the bull's eye bearing 3206 to squeeze the flip plate 3201 when moving to the right. It should be understood here that the power for the rotation of the flip plate 3201 all comes from the power generated when the bull's eye bearing 3206 moves. Therefore, when the bull's eye bearing 3206 does not move, the flip plate 3201 will not rotate either, and there will be no problem of the bull's eye bearing 3206 and the flip plate 3201 being out of contact. The problem is that the flip plate 3201 rotates around the center of the rotation axis 3203 until the extrusion plate 3204 fixed on the inner wall of the flip plate 3201 moves to the top of the push plate 3205. When the line inspection is completed, the staff will push the gate 207 to rotate upward, thereby pushing the lifting plate 3112 and the push plate 3205 to the position of the extrusion plate 3204 until the push plate 3205 contacts the slide 3208. When the push plate 3205 contacts the slide 3208, the slide 3208 and the extrusion plate 3204 are pushed to the right by utilizing the low friction coefficient of the slide 3208 surface. This can then drive the flip plate 3201 to also rotate around the rotation axis 32 03 rotates, pushing the bull's eye bearing 3206 and the second circular block 3202 to squeeze the first circular block 3115, so that the first circular block 3115 can re-enter the second circular cylinder 3107. At this time, the first long plate 3106 will move forward again under the action of the fourth force spring 3113, and the card shaft 3108 fixed on the front of the first long plate 3106 will contact the back of the lifting plate 3112, thereby completing the reset of the limiting unit 31. When the worker disconnects the gate 207 next time, the card shaft 3108 will once again be stuck in the circular hole opened on the front of the lifting plate 3112, preventing the worker who forgets to inspect the line connection from closing the gate 207.
