Background

The GIS equipment plays an important role in the high-voltage electric transportation process, and an isolating switch in the GIS equipment is used as an important component of the GIS equipment, and whether the opening and closing between a moving contact and a static contact of the GIS equipment are in place determines the circuit on-off of the whole GIS equipment.

When the switch-on of a moving contact and a static contact of the isolating switch is not in place, the connecting resistance between the moving contact and the static contact is increased, so that under the condition of larger load current, the two contacts generate great heat, and even the two contacts can be burnt to cause insulation degradation breakdown, thereby causing short-circuit fault; when a certain part of the GIS equipment breaks down, the isolating switch needs to be switched off, the moving contact and the static contact are disconnected, and then the whole GIS equipment circuit is disconnected. Therefore, whether the disconnecting switch is switched on or off in place needs to be clearly judged and indicated so as to protect the personal safety of related workers.

In the prior art, an opening and closing indication of an isolating switch is often displayed through an opening and closing indication device, the opening and closing indication device and a body moving contact of the isolating switch are arranged in a split mode and are in transmission connection with an operating mechanism through a transmission mechanism, the operating mechanism controls the opening and closing indication device to synchronously work in the process of controlling the opening and closing of the moving contact and a fixed contact of the isolating switch body, when the moving contact and the fixed contact complete the opening and closing, the opening and closing indication device displays the completion of the opening and closing, and when the moving contact and the fixed contact complete the opening and closing, the opening and closing indication device displays the completion of the opening and closing.
