Fracture position indicating device of GIS isolation switch

Technical Field

The utility model belongs to the technical field of GIS switch fracture position judgement, concretely relates to fracture position indicating device of GIS isolation switch.

Background

During the operation of the power system, switching operation is often performed due to the change of the operation mode, and in the switching operation of the high-voltage equipment, as shown in fig. 1 and fig. 2, an important part is to check and confirm the opening and closing conditions of the isolation (grounding) disconnecting link, so that serious misoperation accidents that the grounding disconnecting link is not opened and should be closed can be avoided, such as the grounding disconnecting link, and the like. The particularity of the GIS isolating (grounding) disconnecting link structure, whether horizontally arranged or vertically installed, the GIS isolating (grounding) disconnecting link installed at a high position cannot visually judge the fracture position, and the GIS isolating (grounding) disconnecting link structure is based on the state indicating plate of the operating mechanism box in a turning and separating and combining way and assisted by an electric indicating lamp in a convergence control cabinet and a remote DCS or NCS system state indicating lamp. The operating mechanism box state indication is that the indicating board of the 'separating' and 'closing' state is turned over by the rotation of the connecting rod which drives the disconnecting link to separate and close in the operating mechanism box; if the driving connecting rod is deformed and the indicating plate falls off, the indication is wrong. The most reliable method is based on observing the fracture of the moving contact and the static contact of the disconnecting link, but under the influence of a GIS structure and a field installation environment, the installation positions of some isolating (grounding) disconnecting links are too high, the mechanical fracture position peeping ports of some isolating (grounding) disconnecting links exceed 2 meters or even 3 meters above the ground, the fracture state can be observed only by climbing GIS equipment, and great operation injury risks exist to both human bodies and the equipment; moreover, as the GIS equipment is compactly installed, a special ladder stand or a high stool is inconvenient to install so that an operator can check the fracture position state; therefore, the GIS isolation (grounding) disconnecting link cannot directly check the mechanical fracture position, and the opening and closing position can only be judged by the operating mechanism box state indicating plate, so that great risk exists in switching operation.
