Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment, and particularly relates to an arc extinguishing chamber assembly tooling and an assembly method for a GIS circuit breaker. Background Art

[0002] A GIS circuit breaker is a device used to implement the function of a GIS switch, which can play roles such as protecting and controlling a circuit. The GIS circuit breaker mainly includes a housing and an arc extinguishing chamber. The arc extinguishing chamber is installed inside the housing, and the moving contact of the arc extinguishing chamber is inserted into the support structure inside the housing. As the voltage level increases, the volume and weight of the arc extinguishing chamber also continuously increase, resulting in a further increase in the installation difficulty of the arc extinguishing chamber, a further reduction in the installation efficiency, and due to the limitation of the installation space, during installation, assembly personnel are prone to cause a rigid collision between the arc extinguishing chamber and the housing due to careless operation, and then it is easy to cause surface bumps and scratches on the arc extinguishing chamber or the housing, which affects the performance of the GIS equipment. Especially when inserting the moving contact of the arc extinguishing chamber into the support structure inside the housing, it is difficult to determine whether the arc extinguishing chamber is inserted in place, so it is easy to cause unstable installation or rigid collision due to over - insertion between the moving contact and the support structure, seriously affecting the performance of the GIS equipment. For this reason, the prior art usually installs a position sensor and a speed sensor inside the housing to ensure that the arc extinguishing chamber can be inserted into the support structure in place and reduce the rigid collision between the two. However, the setting of precise instruments such as position sensors and speed sensors will increase the cost. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this purpose, the present invention provides an arc extinguishing chamber assembly tooling for a GIS circuit breaker, which can accurately install the arc extinguishing chamber inside the housing without adding sensors, save manpower, and reduce the risk of bumps and scratches on the surfaces of the arc extinguishing chamber and the support structure.

[0037] Refer to Figures 1 to 6, an embodiment of the present invention provides an arc extinguishing chamber assembly tool for a GIS circuit breaker, including a hoisting device (not shown in the figure), a trolley 200, a first magnetic device 260, and a second magnetic device. The hoisting device is arranged outside the housing 400 of the GIS circuit breaker. The hoisting device has a first sling 100 and a second sling 110. The first sling 100 is used to hoist one end of the arc extinguishing chamber 500 close to the housing 400, and the second sling 110 is used to hoist the end of the arc extinguishing chamber 500 far from the housing 400; the trolley 200 is movably arranged inside the housing 400. The trolley 200 is provided with a vehicle body 210 and a telescopic component for carrying the arc extinguishing chamber 500. The telescopic component is in rolling or sliding cooperation with the vehicle body 210; the first magnetic device 260 is fixedly arranged on the telescopic component or the arc extinguishing chamber 500, and the first magnetic device 260 can move along with the arc extinguishing chamber 500; the second magnetic device includes a first electromagnetic component 300 and a plurality of second electromagnetic components 310. The first electromagnetic component 300 and the plurality of second electromagnetic components 310 are installed in the housing 400 at intervals along the axial direction of the housing 400. All the second electromagnetic components 310 are arranged at intervals on one side of the first electromagnetic component 300 facing away from the mounting hole 420 of the housing 400. When the first electromagnetic component 300 is energized, it can generate a repulsive force that repels the first magnetic device 260, and when the second electromagnetic component 310 is energized, it can generate an attractive force that attracts the first magnetic device 260; when the arc extinguishing chamber 500 is outside the housing 400, the first sling 100 and the second sling 110 can cooperate to hoist the arc extinguishing chamber 500, and the hoisting device can push the arc extinguishing chamber 500 in the direction close to the housing 400 to a first position; when the arc extinguishing chamber 500 is at the first position, the first sling 100 is close to the edge of the mounting hole 420, the arc extinguishing chamber 500 passes through the mounting hole 420, and one end of the arc extinguishing chamber 500 located inside the housing 400 can be carried on the telescopic component on the vehicle body 210. The first sling 100 releases the arc extinguishing chamber 500, and the trolley 200 can cooperate with the second sling 110 to support the arc extinguishing chamber 500; the hoisting device can push the arc extinguishing chamber 500 and the trolley 200 in the direction close to the support structure 410 inside the housing 400 to a second position; when the arc extinguishing chamber 500 is at the second position, there is a distance between the arc extinguishing chamber 500 and the support structure 410. The hoisting device stops working, the vehicle body 210 stops moving, and the telescopic component can extend relative to the vehicle body 210 in the direction close to the support structure 410 under the action of inertia, and perform a first operation on the second magnetic device. The first operation is to energize the first electromagnetic component 300 or the second electromagnetic component 310 for N seconds and then de-energize them in sequence along the moving direction of the arc extinguishing chamber 500, where N>0; the repulsive force generated by the first electromagnetic component 300 can reduce the moving speed of the arc extinguishing chamber 500, and the attractive forces generated by the respective second electromagnetic components 310 can pull the arc extinguishing chamber 500 to move closer to the corresponding second electromagnetic components 310 in sequence along the axial direction of the housing 400 until the arc extinguishing chamber 500 moves to a preset position and the arc extinguishing chamber 500 is inserted in place with the support structure 410.

[0038] In the arc extinguishing chamber assembly tool of the GIS circuit breaker of the embodiment of the present invention, the arc extinguishing chamber 500 is first moved to the first position by using the first sling 100 and the second sling 110 of the lifting device, so that the arc extinguishing chamber 500 is inserted into the mounting hole 420 of the housing 400, and the first sling 100 is close to the edge of the mounting hole 420. At this time, the end of the arc extinguishing chamber 500 located in the housing 400 can be mounted on the cart 200, and the first sling 100 is loosened, so that the arc extinguishing chamber 500 can be moved from the first position to the second position by the lifting device and the cart 200. This process can make the arc extinguishing chamber 500 more convenient to move in. By arranging a telescopic component for carrying the arc extinguishing chamber 500 on the vehicle body 210, the telescopic component can be extended relative to the vehicle body 210 when the vehicle body 210 stops moving, so that the arc extinguishing chamber 500 can continue to move forward. In this process, by setting the first magnetic device 260 and the second magnetic device, the first magnetic device 260 and the second magnetic device can cooperate to guide the arc extinguishing chamber 500 to gradually move forward from the second position to the preset position, thereby making the GIS circuit breaker arc extinguishing chamber assembly tooling of the present invention not only save manpower, but also can accurately insert the arc extinguishing chamber 500 into the supporting structure 410 inside the shell 400 without adding position sensors and speed sensors, thereby reducing the risk of bumps and scratches on the surface of the arc extinguishing chamber 500 and the shell 400 while also reducing costs.

[0039] Specifically, the first magnetic device 260 is fixedly installed on the telescopic assembly or the arc extinguishing chamber 500. The second magnetic device includes a first magnetic component and a plurality of second magnetic components. The first electromagnetic component 300 and the plurality of second electromagnetic components 310 are installed in the housing 400 at intervals along the axial direction of the housing 400. All the second electromagnetic components 310 are arranged at intervals on one side of the first electromagnetic component 300 facing away from the mounting hole 420 of the housing 400. When the first electromagnetic component 300 is energized, it can generate a repulsive force that repels the first magnetic device 260. When the second electromagnetic component 310 is energized, it can generate an attractive force that attracts the first magnetic device 260. Thus, when the vehicle body 210 stops at the second position, the telescopic assembly can extend relative to the vehicle body 210 in the direction close to the support structure 410 under the action of inertia. At this time, a first operation is performed on the second magnetic device. The first electromagnetic component 300 or the second electromagnetic component 310 is energized for N seconds and then powered off in sequence along the moving direction of the arc extinguishing chamber 500. The repulsive force generated when the first electromagnetic component 300 is energized can reduce the moving speed of the arc extinguishing chamber 500, thereby avoiding the arc extinguishing chamber 500 moving forward at a relatively high speed under the action of inertia and colliding with the support structure 410. When the first electromagnetic component 300 is powered off, the arc extinguishing chamber 500 is located at the third position. An operation of energizing and then powering off the second electromagnetic component 310 in sequence along the moving direction of the arc extinguishing chamber 500 is performed. The attractive force generated when the second electromagnetic component 310 is energized can pull the arc extinguishing chamber 500 to move axially along the housing 400 and approach the corresponding second electromagnetic component 310. That is, when the first second electromagnetic component 310 close to the first electromagnetic component 300 is energized, the arc extinguishing chamber 500 can be pulled from the third position forward to the fourth position corresponding to the first second electromagnetic component 310. After the first second electromagnetic component 310 is powered off, when the second second electromagnetic component 310 close to the first electromagnetic component 300 is energized, the arc extinguishing chamber 500 can be pulled from the fourth position forward to the fifth position corresponding to the second second electromagnetic component 310. And so on, the operation of energizing the subsequent other second electromagnetic components 310 for N seconds and then powering off is performed in sequence, and then the arc extinguishing chamber 500 can be pulled to move forward to the positions corresponding to the respective second electromagnetic components 310 in sequence until reaching the preset position. Thus, the setting of the first magnetic device 260 and the second magnetic device can divide the process of moving the arc extinguishing chamber 500 from the second position to the preset position into multiple sub-processes and proceed step by step, guiding the arc extinguishing chamber 500 to move in segments, so that it is possible to guide the arc extinguishing chamber 500 to move forward step by step and accurately reach the preset position without setting a sensor. Not only can the arc extinguishing chamber 500 be inserted into place with the support structure 410, but also the risk of bumps and scratches on the surfaces of the arc extinguishing chamber 500 and the support structure 410 can be greatly reduced.

[0040] It can be understood that in order to guide the arc extinguishing chamber 500 to gradually move to a preset position when the vehicle body 210 stops at the second position, in addition to performing the first operation on the second magnetic device, the second operation can also be performed on the second magnetic device. The second operation is specifically to first energize the second magnetic device, and then sequentially de-energize the first electromagnetic component 300 or the second electromagnetic component 310 along the moving direction of the arc extinguishing chamber 500. Thus, when the vehicle body 210 stops at the second position, the telescopic component can extend relative to the vehicle body 210 in the direction close to the support structure 410 under the action of inertia. At this time, the second operation is performed on the second magnetic device. First, both the first electromagnetic component 300 and the second electromagnetic component 310 in the second magnetic device are energized, and the repulsive force generated by the first electromagnetic component 300 is used to decelerate the movement of the arc extinguishing chamber 500. Then, the first electromagnetic component 300 is first de-energized. At this time, the arc extinguishing chamber 500 is located at the third position, and the attractive force generated by each second electromagnetic component 310 can pull the arc extinguishing chamber 500 to move forward from the third position. When the arc extinguishing chamber 500 moves to the fourth position corresponding to the first second electromagnetic component 310 close to the first electromagnetic component 300, the first second electromagnetic component 310 close to the first electromagnetic component 300 is de-energized. At this time, the attractive force generated by the other second electromagnetic components 310 can pull the arc extinguishing chamber 500 to continue to move forward. When the arc extinguishing chamber 500 moves from the fourth position to the fifth position of the second second electromagnetic component 310 close to the first electromagnetic component 300, the second second electromagnetic component 310 close to the first electromagnetic component 300 is de-energized. At this time, the attractive force generated by the other second electromagnetic components 310 can pull the arc extinguishing chamber 500 to continue to move forward. And so on, the subsequent other second electromagnetic components 310 are sequentially de-energized, and thus the arc chamber can be pulled to gradually move forward to the positions corresponding to the respective second electromagnetic components 310 until reaching the preset position. Therefore, the process of moving the arc extinguishing chamber 500 from the second position to the preset position can also be divided into multiple sub-processes to be carried out step by step, guiding the segmented movement of the arc extinguishing chamber 500, so that the arc extinguishing chamber 500 can be guided to gradually move forward and accurately reach the preset position without setting sensors. It can not only insert the arc extinguishing chamber 500 and the support structure 410 in place, but also greatly reduce the risk of collision and scratch on the surfaces of the arc extinguishing chamber 500 and the support structure 410.

[0041] In some embodiments, two or more sets of second electromagnetic devices may also be provided, so as to divide the process of moving the arc extinguishing chamber 500 from the second position to the preset position into more sub-processes, making the insertion between the arc extinguishing chamber 500 and the support structure 410 more precise, and further reducing the risk of collision and scratching between the arc extinguishing chamber 500 and the support structure 410. When there are two or more sets of second electromagnetic devices, during the process of moving the arc extinguishing chamber 500 from the second position to the preset position, a first operation may be sequentially performed on each set of second electromagnetic devices along the moving direction of the arc extinguishing chamber 500, or a second operation may be sequentially performed on each set of second electromagnetic devices along the moving direction of the arc extinguishing chamber 500. In addition, when performing on-off operations on each set of second electromagnetic devices in sequence along the moving direction of the arc extinguishing chamber 500, at least one set of second electromagnetic components 310 may perform the first operation, and at least one set of second electromagnetic components 310 may perform the second operation. The present invention does not make specific limitations on this.

[0042] It can be understood that in the first operation and the second operation, the repulsive force generated by the first electromagnetic component 300 can be controlled to reduce the moving speed of the arc extinguishing chamber 500 to zero, that is, the movement of the arc extinguishing chamber 500 is controlled to stop by the repulsive force generated by the first electromagnetic component 300, and then the arc extinguishing chamber 500 is gradually pulled to the preset position by each second electromagnetic component 310.

[0043] It can be understood that for the first operation and the second operation, the on-off time of the first electromagnetic component 300 and the second electromagnetic component 310 can be specifically controlled for regulation.

[0044] It can be understood that the first magnetic device 260 may specifically adopt a permanent magnet, and the permanent magnet can be installed on the telescopic component or the arc extinguishing chamber 500 through a bracket.

[0045] It can be understood that the first electromagnetic component 300 and the second electromagnetic component 310 in the second magnetic device may specifically adopt a structure of an iron core plus a coil, that is, the coil is wound around the outer periphery of the iron core, and the repulsive force of the first electromagnetic component 300 and the attractive force of the second electromagnetic component 310 are controlled by energizing or de-energizing the coil.

[0046] Referring to Figures 1 to 6 , in some embodiments, the arc extinguishing chamber 500 has a plug joint 511, and the support structure 410 has a plug-in portion 411 that cooperates with the plug joint 511 for plugging. When the arc extinguishing chamber 500 is in the second position, the plug joint 511 is adjacent to the plug-in portion 411. The first electromagnetic component 300 and all the second electromagnetic components 310 are installed on the outer wall of the plug-in portion 411 along the axial direction of the housing 400, and the first magnetic device 260 is installed on the plug joint 511.

[0047] By adopting the above structure, the first magnetic device 260 is directly installed on the plug connector 511 of the arc extinguishing chamber 500, and the second magnetic device is directly installed on the outer wall of the insertion part 411 of the support structure 410, so that it is convenient to more accurately guide the plug connector 511 to accurately insert into the insertion hole of the support structure 410 through the first magnetic device 260 and the second magnetic device.

[0048] It can be understood that the first magnetic device 260 and the second magnetic device can be removed after the installation of the arc extinguishing chamber 500 is completed. Since the second magnetic device is installed on the outer wall of the insertion part 411, it is convenient to remove the second magnetic device from the support structure 410 after the installation of the arc extinguishing chamber 500 is completed, so as to avoid the influence of the second magnetic device on the subsequent use of the GIS circuit breaker.

[0049] In some embodiments, the first electromagnetic assembly 300 and all the second electromagnetic assemblies 310 are installed on the inner wall of the housing 400 along the axial direction of the housing 400 and are located on the side of the second position away from the mounting hole 420, and the first magnetic device 260 is installed on the telescopic assembly and can move relative to the vehicle body 210 following the telescopic assembly.

[0050] By adopting the above structure, the first magnetic device 260 is installed on the telescopic assembly. Since the arc extinguishing chamber 500 is carried on the telescopic assembly, the telescopic assembly can be guided to move forward step by step, thereby driving the arc extinguishing chamber 500 to move forward step by step to a preset position. And since the first magnetic device 260 is installed on the telescopic assembly, it is convenient to move the first telescopic assembly and the first magnetic device 260 out of the housing 400 together after the installation of the arc extinguishing chamber 500 is completed.

[0051] Refer to Figures 1 to 6 , in some embodiments, a braking device is provided between the vehicle body 210 and the housing 400, and the braking device can control the vehicle body 210 to stop moving at the second position; a first roller assembly is installed at the lower end of the vehicle body 210, and the first roller assembly includes two first rollers 240 arranged at intervals along the radial direction of the housing 400 and in contact with the inner wall of the housing 400. The telescopic assembly includes a fixed bracket 220 and a movable bracket 230. The fixed bracket 220 is installed at the upper end of the vehicle body 210, and the movable bracket 230 is slidably installed on the fixed bracket 220. The movable bracket 230 is used to support the arc extinguishing chamber 500; when the vehicle body 210 stops moving, the movable bracket 230 can drive the arc extinguishing chamber 500 to move relative to the fixed bracket 220 along the axis direction of the housing 400 under the action of inertia.

[0052] By adopting the above structure, the braking device can be conveniently set to prevent the vehicle body 210 from continuing to move forward after the crane device stops working, so that the vehicle body 210 can stop moving at the second position, and further enable the arc extinguishing chamber 500 and the telescopic assembly to gradually move forward under the action of the second magnetic device. The telescopic assembly includes a fixed bracket 220 and a movable bracket 230. The movable bracket 230 can support the arc extinguishing chamber 500, and the fixed bracket 220 can stably support the movable bracket 230, so that the movable bracket 230 can stably move forward relative to the fixed bracket 220 together with the arc extinguishing chamber 500.

[0053] It can be understood that in order to make the movement of the vehicle body 210 smoother, in addition to the first roller assembly, a second roller assembly can also be added. The second roller assembly includes two second rollers 250 arranged at intervals along the radial direction of the housing 400 and in contact with the inner wall of the housing 400.

[0054] It can be understood that in order to enable the vehicle body 210 to adapt to the arc-shaped inner wall of the housing 400, the two first rollers 240 in the first roller assembly can be inclinedly installed on the vehicle body 210 so that an included angle is formed between the two first rollers 240. Similarly, the two second rollers 250 in the second roller assembly can also be inclinedly installed on the vehicle body 210 so that an included angle is formed between the two second rollers 250.

[0055] Refer to Figures 1 to 6 , in some embodiments, a maintenance opening 430 is provided in the side wall of the housing 400 and arranged in the up-down direction. The maintenance opening 430 is located at the bottom of the housing 400 and on one side of the support structure 410, and the second position is located on the side of the maintenance opening 430 away from the support structure 410.

[0056] By adopting the above structure, the setting of the maintenance opening 430 can not only facilitate the inspection and maintenance of the internal structure of the housing 400, but also facilitate the removal of auxiliary installation structures such as the trolley 200, the first electromagnetic device, and the second electromagnetic device inside the housing 400 from the maintenance opening 430 after the arc extinguishing chamber 500 is installed. In addition, by setting the second position on the side of the maintenance opening 430 away from the support structure 410, the risk of the trolley 200 falling into the maintenance opening 430 during the movement can be reduced, making the installation process of the arc extinguishing chamber 500 more stable.

[0057] Refer to Figures 1 to 6, in some embodiments, the braking device includes magnetic members 320 corresponding to the two first rollers 240 one by one. The magnetic members 320 are disposed on the outer sidewall of the housing 400 and are located on the rolling paths of the corresponding first rollers 240. On the axis of the housing 400, the magnetic members 320 are arranged corresponding to the second position or are located on the side of the second position away from the maintenance opening 430; each first roller 240 has a magnetic attracting portion, and the magnetic member 320 can attract the corresponding magnetic attracting portion and prevent the trolley 200 from moving, so that the trolley 200 stays at the second position.

[0058] By adopting the above structure, the first roller 240 is magnetically attracted by the magnetic member 320 and the first roller 240 is magnetically attracted to the second position, preventing the first roller 240 from continuing to move forward, thereby making the trolley 200 stay at the second position.

[0059] It can be understood that the magnetic member 320 can specifically adopt an electromagnetic structure of an iron core plus a coil to generate a magnetic attraction force that attracts the magnetic attracting portion through energization. Alternatively, the magnetic member 320 can also directly adopt a magnet, and the present invention does not make specific limitations in this regard.

[0060] It can be understood that the magnetic attracting portion located on the first roller 240 can specifically be a magnetic metal or a magnet installed on the first roller 240. The magnetic attracting portion can be installed on the hub of the first roller 240, or can also be installed on the surface of the wheel body of the first roller 240 in contact with the inner wall of the housing 400. In addition, the wheel body of the first roller 240 can also be directly set as the magnetic attracting portion, and the present invention does not make specific limitations in this regard.

[0061] Refer to Figures 1 to 6 , in some embodiments, the movable bracket 230 includes a supporting portion 231 and a clamping portion 232 that are detachably connected. The supporting portion 231 is slidably installed on the fixed bracket 220. The clamping portion 232 is located above the supporting portion 231 and can cooperate with the supporting portion 231 to clamp the arc extinguishing chamber 500. Flexible members 233 are provided on the upper surface of the supporting portion 231 and the lower surface of the clamping portion 232.

[0062] By adopting the above structure, the arc extinguishing chamber 500 can be clamped and fixed through the cooperation of the supporting portion 231 and the clamping portion 232, so that the movable bracket 230 can conveniently drive the arc extinguishing chamber 500 to move forward together. By providing the flexible members 233 on the upper surface of the supporting portion 231 and the lower surface of the clamping portion 232, the arc extinguishing chamber 500 can be protected, and the surface of the arc extinguishing chamber 500 can be prevented from being damaged due to rigid contact with the surfaces of the supporting portion 231 and the clamping portion 232.

[0063] It can be understood that the flexible member 233 can specifically adopt a rubber member or a silicone member, etc., and the present invention does not make specific limitations in this regard.

[0064] Reference Figures 1 to 6 In some embodiments, the arc extinguishing chamber 500 includes an arc extinguishing chamber body 510, a supporting conductor 520 and a pot-type insulator 530. The arc extinguishing chamber body 510 has a static end 512 and a moving end 513. The static end 512 is installed on the supporting conductor 520. The plug connector 511 is arranged on the moving end 513. The moving end 513 is also provided with a sealing tube 514 sleeved on the outer periphery of the plug connector 511. The sealing tube 514 can be clamped between the supporting portion 231 and the clamping portion 232. The pot-type insulator 530 is installed on one end of the supporting conductor 520 away from the arc extinguishing chamber body 510. The arc extinguishing chamber body 510 is provided with a first hanging point 515 for hanging in cooperation with the first hanging belt 100. The first hanging point 515 is arranged close to the moving end 513. The pot-type insulator 530 is provided with a second hanging point 531 for hanging in cooperation with the second hanging belt 110.

[0065] By adopting the above structure, the arc extinguishing chamber body 510, the supporting conductor 520 and the pot-type insulator 530 can be installed as a whole outside the housing 400, so that the arc extinguishing chamber body 510, the supporting conductor 520 and the pot-type insulator 530 are not easily restricted by the installation space, and then the whole is installed together into the housing 400 through the lifting device and the trolley 200 and other structures, thereby making the installation of the arc extinguishing chamber body 510, the supporting conductor 520 and the pot-type insulator 530 simpler and more convenient. By setting the first lifting point 515 on the arc extinguishing chamber body 510 and the second lifting point 531 on the pot-type insulator 530, the lifting device can be lifted from both ends of the overall structure of the arc extinguishing chamber 500 through the first lifting belt 100 and the second lifting belt 110, so that the overall lifting of the arc extinguishing chamber 500 is more stable.

[0066] Reference Figures 1 to 4 In some embodiments, the shell 400 has two mounting holes 420, and the two mounting holes 420 are correspondingly opened at opposite ends of the shell 400. The opposite ends of the support structure 410 are provided with plug-in parts 411 that can be plugged in with the arc extinguishing chamber 500. The number of arc extinguishing chambers 500 is two, and the two arc extinguishing chambers 500 are respectively installed in the shell 400 through the two mounting holes 420 and plugged in with the corresponding plug-in parts 411.

[0067] In the above structure, the arc extinguishing chamber 500 is installed in a horizontal double-break series manner. The two arc extinguishing chambers 500 can be installed on the supporting structure 410 inside the shell 400 through two mounting holes 420 respectively through the lifting device, the trolley 200, the first magnetic device 260 and the second magnetic device. There is no need to move the arc extinguishing chamber 500 from one end of the shell 400 into the shell 400 and install it to the other end of the shell 400, which shortens the installation of the arc extinguishing chamber 500 and makes the installation of the arc extinguishing chamber 500 more convenient.

[0068] An embodiment of the present invention further provides an arc extinguishing chamber assembly method for a GIS circuit breaker, which uses the arc extinguishing chamber assembly tooling of the GIS circuit breaker in any of the above embodiments, and specifically includes the following steps:

[0069] S1: Hoist one end of the arc extinguishing chamber 500 close to the housing 400 with the first sling 100, hoist the other end of the arc extinguishing chamber 500 away from the housing 400 with the second sling 110, and push the arc extinguishing chamber 500 from outside the housing 400 to the first position through a hoisting device, and the first sling 100 is close to the edge of the mounting hole 420 of the housing 400;

[0070] S2: Place one end of the arc extinguishing chamber 500 inside the housing 400 on the bearing part, release the first sling 100, and push the arc extinguishing chamber 500 and the trolley 200 to move in the direction close to the support structure 410 to the second position through a hoisting device;

[0071] S3: The hoisting device stops working, the trolley 200 stops moving, and a first operation and / or a second operation is performed on the second magnetic device. The first operation is to sequentially energize the first electromagnetic component 300 or the second electromagnetic component 310 for N seconds and then power off in the moving direction of the arc extinguishing chamber 500; the second operation is to first energize the second magnetic device, and then sequentially power off the first electromagnetic component 300 or the second electromagnetic component 310 in the moving direction of the arc extinguishing chamber 500. The first electromagnetic component 300 can generate a repulsive force that repels the first magnetic device 260 and reduce the moving speed of the arc extinguishing chamber 500. Each second electromagnetic component 310 can generate an attractive force that attracts the first magnetic device 260, and pull the arc extinguishing chamber 500 to move axially along the housing 400 to approach the corresponding second electromagnetic component 310 in sequence until the arc extinguishing chamber 500 moves to a preset position and the arc extinguishing chamber 500 is inserted in place with the support structure 410.

[0072] In the arc extinguishing chamber assembly method of the GIS circuit breaker according to the embodiments of the present invention, by adopting the arc extinguishing chamber assembly tooling of the GIS circuit breaker in any of the above embodiments, when installing the arc extinguishing chamber 500, the arc extinguishing chamber 500 can be first moved to the first position by using the first sling 100 and the second sling 110 of the hoisting device in step S1, so that the arc extinguishing chamber 500 passes through the mounting hole 420 of the housing 400, and the first sling 100 is adjacent to the edge of the mounting hole 420. Then, in step S2, one end of the arc extinguishing chamber 500 located inside the housing 400 can be placed on the telescopic assembly of the trolley 200, and the first sling 100 is loosened. Thus, the arc extinguishing chamber 500 can be moved from the first position to the second position by the cooperation of the hoisting device and the trolley 200, and this process can make the installation of the arc extinguishing chamber 500 more convenient. Then, in step S3, the hoisting device is controlled to stop working, and the trolley 200 is controlled to stop moving. At this time, the telescopic assembly can extend relative to the vehicle body 210 when the vehicle body 210 stops moving, so that the arc extinguishing chamber 500 can continue to move forward. During this process, due to the setting of the first magnetic device 260 and the second magnetic device, by performing the first operation and / or the second operation on the second magnetic device, the first magnetic device 260 and the second magnetic device can cooperate to guide the arc extinguishing chamber 500 to move forward step by step from the second position to the preset position. Therefore, the arc extinguishing chamber assembly tooling of the GIS circuit breaker of the present invention can not only save manpower, but also accurately insert the arc extinguishing chamber 500 into the support structure 410 inside the housing 400 without installing position sensors and speed sensors, reduce the risk of bumps and scratches on the surfaces of the arc extinguishing chamber 500 and the housing 400, and also reduce costs, which is beneficial to improving the performance of the GIS circuit breaker and further beneficial to improving the performance of the GIS equipment.

[0073] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the spirit of the present invention.
