Abstract

The utility model relates to a rainproof cover for a knife gate mechanism, which relates to a rainproof cover for an outdoor isolating switch. The connection between the traditional isolation switch rotating link and the mechanism box is not tightly sealed, resulting in the infiltration of raindrops and the DC grounding of the system. The rain cover of the knife gate mechanism is in the shape of a trumpet with an upper opening and a lower opening, the upper opening is hooped on the cylindrical surface of the rotating link of the isolation switch and forms a seal at the connection, and the lower opening is located in the box body of the knife gate mechanism. superior. According to the invention, a rainproof cover with a downward trumpet-shaped opening is installed at the connection between the rotating connecting rod of the isolation switch and the box body of the knife gate mechanism, so as to avoid the DC grounding of the system. The invention is used for the rainproof protection of the outdoor isolation switch in the electric power industry.

Description

technical field [0001] The invention relates to an isolating switch rainproof cover, in particular to a power system isolating switch rainproof cover. Background technique [0002] The connecting part of the connecting rod of the traditional isolating switch and the box of the isolating switch mechanism is a straight-through connection. Although this design ensures safety, in rainy and snowy weather, due to the sealing of the connecting rod of the isolating switch and the box of the mechanism If it is not strict, it will cause raindrops to infiltrate and cause the DC grounding of the system. In the case of two-point grounding, it will cause the relay protection device to refuse to operate or malfunction, seriously affecting the stable operation of the power system and affecting the comprehensive automation assessment indicators. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the system is easily grounded in rainy and sn...
