The arc extinguishing chamber is installed in the shell and the moving contact of the arc extinguishing chamber is plugged into the supporting structure inside the shell. With the increase of voltage level, the volume and weight of the arc extinguishing chamber are also increasing, which makes the installation of the arc extinguishing chamber more difficult and reduces the installation efficiency. Due to the limitation of installation space, the assembler may cause a rigid collision between the arc extinguishing chamber and the shell due to careless operation during installation, which may cause surface bumps and scratches on the arc extinguishing chamber or the shell, affecting the performance of the GIS equipment. In particular, when the moving contact of the arc extinguishing chamber is inserted into the supporting structure in the shell, it is difficult to judge whether the arc extinguishing chamber is inserted in place, which may easily lead to unstable installation between the moving contact and the supporting structure or rigid bumps due to over-installation, which seriously affects the performance of the GIS equipment. To this end, the prior art usually installs position sensors and speed sensors inside the shell to ensure that the arc extinguishing chamber can be inserted into the supporting structure in place and reduce the rigid collision between the two.

[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 fixed to the telescopic assembly or the arc extinguishing chamber 500, and the second magnetic device includes a first magnetic assembly and a plurality of second magnetic assemblies. The first electromagnetic assembly 300 and the plurality of second electromagnetic assemblies 310 are installed in the housing 400 along the axial interval of the housing 400, and all the second electromagnetic assemblies 310 are arranged at intervals on the side of the first electromagnetic assembly 300 away from the mounting hole 420 of the housing 400. When the first electromagnetic assembly 300 is energized, a repulsive force mutually repelling the first magnetic device 260 can be generated, and when the second electromagnetic assembly 310 is energized, a repulsive force mutually repelling the first magnetic device 260 can be generated. The attraction of mutual attraction, therefore, when the vehicle body 210 stops at the second position, the telescopic assembly can be extended relative to the vehicle body 210 in the direction close to the support structure 410 under the action of inertia. At this time, the first operation is performed on the second magnetic device, and the first electromagnetic assembly 300 or the second electromagnetic assembly 310 is energized for N seconds and then de-energized in sequence along the moving direction of the arc extinguishing chamber 500. The repulsive force generated when the first electromagnetic assembly 300 is energized can reduce the moving speed of the arc extinguishing chamber 500, thereby preventing the arc extinguishing chamber 500 from moving forward at a faster speed under the action of inertia and colliding with the support structure 410. When the first electromagnetic assembly 300 is powered off, the arc extinguishing chamber 500 is located at the third position, and the second electromagnetic assemblies 310 are powered on and then powered off in sequence along the moving direction of the arc extinguishing chamber 500. The attraction generated when the second electromagnetic assembly 310 is powered on can pull the arc extinguishing chamber 500 to move along the axial direction of the shell 400 close to the corresponding second electromagnetic assembly 310, that is, when the first second electromagnetic assembly 310 close to the first electromagnetic assembly 300 is powered on, the arc extinguishing chamber 500 can be pulled forward from the third position to the fourth position corresponding to the first second electromagnetic assembly 310. After the first second electromagnetic assembly 310 is powered off, when the second second electromagnetic assembly 310 close to the first electromagnetic assembly 300 is powered on again, the arc extinguishing chamber 500 can be pulled forward from the fourth position to the fifth position corresponding to the second second electromagnetic assembly 310. Similarly, the operation of first powering on for N seconds and then powering off is performed on other second electromagnetic assemblies 310 required later, so that the arc extinguishing chamber 500 can be pulled forward to the positions corresponding to each second electromagnetic assembly 310 in sequence until it reaches the preset position. Therefore, 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 guide the arc extinguishing chamber 500 to move in sections, so that the arc extinguishing chamber 500 can be guided to move forward step by step and accurately reach the preset position without setting up a sensor, which not only allows the arc extinguishing chamber 500 and the supporting structure 410 to be inserted into place, but also greatly reduces the risk of bumps and scratches on the surfaces of the arc extinguishing chamber 500 and the supporting structure 410.

[0040] It can be understood that in order to guide the arc extinguishing chamber 500 to gradually move to the 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 de-energize the first electromagnetic component 300 or the second electromagnetic component 310 in sequence along the moving direction of the arc extinguishing chamber 500. Thus, when the vehicle body 210 stops at the second position, the telescopic assembly can be extended relative to the vehicle body 210 in a 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, the first electromagnetic assembly 300 and the second electromagnetic assembly 310 in the second magnetic device are energized, and the movement of the arc extinguishing chamber 500 is slowed down by the repulsive force generated by the first electromagnetic assembly 300, and then the first electromagnetic assembly 300 is powered off. At this time, the arc extinguishing chamber 500 is located in the third position, and the attraction generated by each second electromagnetic assembly 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 assembly 310 close to the first electromagnetic assembly 300 , the first second electromagnetic component 310 close to the first electromagnetic component 300 is powered off, and the attraction generated by the other second electromagnetic components 310 can pull the arc extinguishing chamber 500 to continue to move forward from the fourth position. 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 powered off, and the attraction generated by the other second electromagnetic components 310 can pull the arc extinguishing chamber 500 to continue to move forward. Similarly, the subsequent second electromagnetic components 310 are powered off in turn, so that the arc chamber can be pulled forward step by step to the positions corresponding to the respective second electromagnetic components 310 until the preset position is reached. In this way, the process of moving the arc extinguishing chamber 500 from the second position to the preset position can be divided into multiple sub-processes and carried out step by step, guiding the arc extinguishing chamber 500 to move in sections, so that the arc extinguishing chamber 500 can be guided to move forward step by step and accurately reach the preset position without setting up sensors. Not only can the arc extinguishing chamber 500 and the supporting structure 410 be inserted into place, but the risk of bumps and scratches on the surfaces of the arc extinguishing chamber 500 and the supporting structure 410 can also be greatly reduced.

[0041] In some embodiments, two or more groups of second electromagnetic devices may 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, so that the insertion between the arc extinguishing chamber 500 and the support structure 410 is more accurate, and the risk of collision and scratch between the arc extinguishing chamber 500 and the support structure 410 is further reduced. When there are two or more groups of second electromagnetic devices, in the process of moving the arc extinguishing chamber 500 from the second position to the preset position, the first operation may be performed on each group of second electromagnetic devices in sequence along the moving direction of the arc extinguishing chamber 500, or the second operation may be performed on each group of second electromagnetic devices in sequence along the moving direction of the arc extinguishing chamber 500. In addition, when performing the power-on and power-off operation on each group of second electromagnetic devices in sequence along the moving direction of the arc extinguishing chamber 500, at least one group of second electromagnetic components 310 may perform the first operation, and at least one group of second electromagnetic components 310 may perform the second operation, and 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 arc extinguishing chamber 500 is controlled to stop moving 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 through each second electromagnetic component 310.

[0043] It is understandable that the first operation and the second operation can be regulated by controlling the power-on and power-off time of the first electromagnetic assembly 300 and the second electromagnetic assembly 310 .

[0044] It is understandable that the first magnetic device 260 may specifically be a permanent magnet, and the permanent magnet may be installed on the telescopic assembly 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 can specifically adopt a structure of an iron core plus a coil, that is, the coil is wound around the outer circumference 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 deenergizing the coil.

[0046] Reference Figures 1 to 6 In some embodiments, the arc extinguishing chamber 500 has a plug connector 511, and the supporting structure 410 has a plug portion 411 that cooperates with the plug connector 511. When the arc extinguishing chamber 500 is located in the second position, the plug connector 511 is adjacent to the plug portion 411, and the first electromagnetic assembly 300 and all the second electromagnetic assemblies 310 are installed on the outer wall of the plug portion 411 along the axial direction of the shell 400, and the first magnetic device 260 is installed on the plug connector 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 plug-in portion 411 of the support structure 410. This makes it possible to more accurately guide the plug connector 511 to be accurately plugged into the plug-in hole of the support structure 410 through the first magnetic device 260 and the second magnetic device.

[0048] It is understandable that the first magnetic device 260 and the second magnetic device can be removed after the arc extinguishing chamber 500 is installed. Since the second magnetic device is installed on the outer wall of the plug-in portion 411, the second magnetic device can be conveniently removed from the supporting structure 410 after the arc extinguishing chamber 500 is installed to avoid the second magnetic device affecting 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 shell 400 along the axial direction of the shell 400 and are located at the second position away from the side of the mounting hole 420. The first magnetic device 260 is installed on the telescopic assembly and can move with the telescopic assembly relative to the vehicle body 210.

[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. Moreover, since the first magnetic device 260 is installed on the telescopic assembly, the first telescopic assembly connected to the first magnetic device 260 can be conveniently moved out of the shell 400 after the arc extinguishing chamber 500 is installed.

[0051] Reference Figures 1 to 6 In some embodiments, a brake device is provided between the vehicle body 210 and the shell 400, and the brake 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 shell 400 and in contact with the inner wall of the shell 400, and 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, and 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 axial direction of the shell 400 under the action of inertia.

[0052] By adopting the above structure, the setting of the brake device can conveniently prevent the vehicle body 210 from moving forward after the crane device stops working, so that the vehicle body 210 can stop moving at the second position, and then the arc extinguishing chamber 500 and the telescopic assembly can 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 with the arc extinguishing chamber 500 relative to the fixed bracket 220.

[0053] It is understandable that in order to make the movement of the vehicle body 210 more stable, in addition to the first roller assembly, a second roller assembly may be provided, the second roller assembly including two second rollers 250 spaced apart along the radial direction of the shell 400 and in contact with the inner wall of the shell 400 .

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

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

[0056] By adopting the above structure, the provision of the maintenance opening 430 can not only facilitate the inspection and maintenance of the structure inside the housing 400, but also facilitate the removal of the auxiliary installation structures such as the cart 200, the first electromagnetic device, the second electromagnetic device, etc. 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 cart 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] Reference Figures 1 to 6In some embodiments, the brake device includes a magnetic member 320 corresponding to the two first rollers 240. The magnetic member 320 is arranged on the outer wall of the shell 400 and is located on the rolling path of the corresponding first roller 240. On the axis of the shell 400, the magnetic member 320 is arranged corresponding to the second position or is located on the side of the second position away from the maintenance port 430; each first roller 240 has a magnetic portion, and the magnetic member 320 can attract the corresponding magnetic portion and prevent the cart 200 from moving, so that the cart 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, thereby preventing the first roller 240 from moving forward, thereby making the cart 200 stay in the second position.

[0059] It is understandable that the magnetic attraction member 320 can specifically adopt an electromagnetic structure of an iron core plus a coil, and generate a magnetic attraction force that attracts the magnetic attraction part by energizing, or the magnetic attraction member 320 can directly adopt a magnet, which is not specifically limited by the present invention.

[0060] It can be understood that the magnetic attraction portion located on the first roller 240 can specifically be a magnetic metal or a magnet installed on the first roller 240, wherein the magnetic attraction 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 that contacts the inner wall of the shell 400. In addition, the wheel body of the first roller 240 can also be directly set as the magnetic attraction portion, and the present invention does not make specific limitations on this.

[0061] Reference 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. The upper surface of the supporting portion 231 and the lower surface of the clamping portion 232 are both provided with flexible parts 233.

[0062] By adopting the above structure, the arc extinguishing chamber 500 can be clamped and fixed by the cooperation of the supporting portion 231 and the clamping portion 232, so that the movable bracket 230 can facilitate the arc extinguishing chamber 500 to move forward together. By providing a flexible member 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 to prevent the arc extinguishing chamber 500 from being damaged due to the rigid contact between the surface of the arc extinguishing chamber 500 and the surfaces of the supporting portion 231 and the clamping portion 232.

[0063] It is understandable that the flexible member 233 may be made of a rubber member or a silicone member, etc., which is not specifically limited in the present invention.

[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 a method for assembling an arc extinguishing chamber of a GIS circuit breaker, using an arc extinguishing chamber assembly tool of a GIS circuit breaker of any of the above embodiments, specifically comprising the following steps:

[0069] S1: hoist the first lifting belt 100 to one end of the arc extinguishing chamber 500 close to the housing 400, and hoist the second lifting belt 110 to one end of the arc extinguishing chamber 500 away from the housing 400, and push the arc extinguishing chamber 500 from the outside of the housing 400 to the first position by the lifting device, with the first lifting belt 100 close to the edge of the mounting hole 420 of the housing 400;

[0070] S2: Mount one end of the arc extinguishing chamber 500 located inside the housing 400 on the bearing portion, release the first lifting belt 100, and push the arc extinguishing chamber 500 and the trolley 200 to move to the second position in a direction close to the supporting structure 410 through the lifting device;

[0071] S3: The lifting device stops working, the trolley 200 stops moving, and the first operation and / or the second operation are performed on the second magnetic device. The first operation is to power on the first electromagnetic assembly 300 or the second electromagnetic assembly 310 in sequence along the moving direction of the arc extinguishing chamber 500 for N seconds and then power off. The second operation is to power on the second magnetic device first, and then power off the first electromagnetic assembly 300 or the second electromagnetic assembly 310 in sequence along the moving direction of the arc extinguishing chamber 500. The first electromagnetic assembly 300 can generate a repulsive force that repel each other with the first magnetic device 260 and reduce the moving speed of the arc extinguishing chamber 500. Each second electromagnetic assembly 310 can generate an attractive force that attracts each other with the first magnetic device 260, and pull the arc extinguishing chamber 500 to move in sequence along the axial direction of the shell 400 close to the corresponding second electromagnetic assembly 310 until the arc extinguishing chamber 500 moves to a preset position and the arc extinguishing chamber 500 and the support structure 410 are inserted into place.

[0072] In the arc extinguishing chamber assembly method of the GIS circuit breaker in the embodiment of the present invention, by adopting the arc extinguishing chamber assembly tool of the GIS circuit breaker in any of the above-mentioned embodiments, when installing the arc extinguishing chamber 500, the arc extinguishing chamber 500 can be moved to the first position by using the first sling 100 and the second sling 110 of the lifting device through step S1, so that the arc extinguishing chamber 500 is inserted into the mounting hole 420 of the shell 400, and the first sling 100 is adjacent to the edge of the mounting hole 420, and then the end of the arc extinguishing chamber 500 located in the shell 400 can be mounted on the telescopic component of the trolley 200 through step S2, 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 through the cooperation of the lifting device and the trolley 200, and this process can make the moving in 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 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, 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, thereby making the arc extinguishing chamber assembly tool of the GIS circuit breaker of the present invention not only save manpower, but also accurately insert the arc extinguishing chamber 500 into the supporting structure 410 inside the shell 400 without installing a position sensor and a speed sensor, reducing the risk of bumps and scratches on the surface of the arc extinguishing chamber 500 and the shell 400, while also reducing 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 are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
