High-voltage isolating switch

Abstract

The invention provides a high-voltage isolation switch. The high-voltage isolation switch is arranged between and connected with isolation intervals of at least one phase of buses and comprises a contact assembly, a moving assembly and a traction assembly, wherein the contact assembly is connected with the traction assembly, the contact assembly is in sliding fit with the buses through the moving assembly, the traction assembly comprises an unmanned aerial vehicle, and the unmanned aerial vehicle can drive the contact assembly to reciprocate between the isolation intervals in the axis direction of the buses so as to allow the isolation intervals to be connected or disconnected. According to the high-voltage isolation switch, a complex operating mechanism and a transmission mechanism are not arranged, the contact assembly linearly reciprocates under the joint cooperation of the moving assembly and the traction assembly, and opening and closing of the contact assembly are driven through the unmanned aerial vehicle, so an insulator can be further omitted, a structure and a matching mode among all the mechanisms are simple, requirements on assembling precision and matching degree are lowered, and overall occupied space is small.
