Description

Technical Field

[0001] The utility model relates to the field of high - voltage combined electrical apparatus power transmission, in particular to a bracket structure for facilitating disassembly and maintenance of a GIS horizontal circuit breaker. Background Art

[0002] At present, the power system plays an increasingly important role in people's daily lives. As a complete set of switchgear, GIS combines components such as circuit breakers, disconnectors, earthing switches, current transformers, voltage transformers, lightning arresters, busbars, incoming and outgoing line bushings or cable terminals, etc., and encloses them in a grounded metal casing, filled with SF6 gas at a certain pressure as the insulating medium. Its structure is simple and the reliability is high. With the long - term operation of GIS equipment, the insulating parts and internal parts may age to varying degrees. During the equipment installation or expansion docking process, there may also be defects such as air leakage and abnormal partial discharge due to improper operation or failure to install strictly in accordance with the process requirements. This requires local disassembly and maintenance of the equipment.

[0003] Since GIS equipment is heavy and not suitable for suspension, and the horizontal GIS layout is often relatively compact, the conventional bracket structure is complex and occupies a large space, making it difficult to install. Therefore, for horizontal circuit breakers, the currently common disassembly method is to disassemble them sequentially from top to bottom. This disassembly method has a large disassembly range and often involves busbar power outage, which has a greater impact on the power system. Summary of the Utility Model

[0004] The purpose of the utility model is to address the problems in the background art and propose a bracket structure for facilitating disassembly and maintenance of a GIS horizontal circuit breaker, which assists in directly lowering and disassembling the horizontal circuit breaker, reducing the possibility of busbar power outage, reducing the on - site workload, and having a simple structure, being easy to manufacture, safe and reliable.

[0005] The technical solution of the utility model is a bracket structure for facilitating disassembly and maintenance of a GIS horizontal circuit breaker, which includes support legs, crossbars, and a pad assembly; the support legs are arranged vertically; the crossbars are arranged horizontally on the tops of the support legs; the pad assembly includes a number of pads a horizontally arranged on the top of the crossbar and a number of pads b horizontally arranged on the bottoms of the support legs.

[0006] Preferably, two support legs are arranged side by side in the horizontal direction.

[0007] Preferably, the crossbar is an H - shaped steel.

[0008] Preferably, the top of the crossbar is connected to the current transformer support cylinder above through bolt a, and both ends of the crossbar are detachably connected to the two support legs through bolt b respectively.

[0009] Preferably, when there are multiple cushion plates a, the multiple cushion plates a are stacked vertically; when there are multiple cushion plates b, the multiple cushion plates b are stacked vertically.

[0010] Compared with the prior art, the utility model has the following beneficial technical effects:

[0011] The structure of the utility model is simple, easy to manufacture, safe and reliable, with good practicability and popularization prospects. The overall height of the support structure is adjusted through the cushion plate assembly, and the cross bar is connected to the current transformer support cylinder above, which can assist in directly achieving the purpose of dropping and disassembling the horizontal circuit breaker, solving the drawback that the disassembly of the current horizontal circuit breaker on site requires a large-scale disassembly from top to bottom, reducing the possibility of bus power outage and the workload on site.

[0015] As Figure 1 and Figure 2 shown, a support structure for facilitating the disassembly and maintenance of a GIS horizontal circuit breaker proposed in this embodiment includes a support leg 1, a cross bar 2, and a cushion plate assembly, and the overall height of the support structure is adjusted by using the cushion plate assembly.

[0016] The support legs 1 are arranged vertically, and two support legs 1 are arranged side by side in the horizontal direction. The two support legs 1 have a good supporting effect on the GIS horizontal circuit breaker, and more support legs 1 can also be further arranged.

[0017] The cross bar 2 is an H-shaped steel, horizontally arranged at the top of the support legs 1. The two ends of the cross bar 2 in the horizontal direction are respectively detachably connected to the two support legs 1, and both are connected by bolts b. The top end of the cross bar 2 is connected to the current transformer support cylinder 100 above through a bolt a5. The current transformer support cylinder 100 has a through hole for the bolt a5 to pass through. After the cross bar 2 and the current transformer support cylinder 100 are connected, other structures below can be disassembled.

[0018] The base plate assembly includes several base plates a3 horizontally arranged on the top of the cross bar 2, and several base plates b4 horizontally arranged at the bottom of the support leg 1. When there are multiple (≥2) base plates a3, the multiple base plates a3 are stacked vertically. When there are multiple (≥2) base plates b4, the multiple base plates b4 are stacked vertically. Both the base plates a3 and the base plates b4 have specifications with different thicknesses and different cross-sectional areas, so as to adjust the height of the bracket structure. The number of base plates can also be selected according to actual application needs.

[0019] The structure of this embodiment is simple, easy to manufacture, safe and reliable, and has good practicability and popularization prospects. The overall height of the bracket structure is adjusted through the base plate assembly, and the number and specifications of the base plates a3 and b4 in the base plate assembly can be flexibly selected. The cross bar 2 is connected to the current transformer support cylinder 100 above, which can assist in directly achieving the purpose of dropping and disassembling the horizontal circuit breaker, solve the drawback that the disassembly of the current horizontal circuit breaker on site requires a large-scale disassembly from top to bottom, reduce the possibility of bus power outage, play an important role in the maintenance and operation of the power system, and also reduce the on-site workload.

[0020] The above has described in detail the embodiments of the present invention in conjunction with the drawings. However, the present invention is not limited to this. Various changes can be made without departing from the gist of the present invention within the scope of knowledge possessed by those skilled in the art to which the present invention pertains.
