Problems solved by technology

The existing high-voltage isolating switch usually has four parts: an operating mechanism, a transmission device, an insulator and a main circuit. The output power of the operating mechanism drives the transmission device to transmit the power to the main circuit to realize the opening and closing operation. This structure has the following defects. First, The operating mechanism must be electric, pneumatic or hydraulic, and the working principle, circuit layout and structural assembly are relatively complicated; second, the transmission device has various structures and many joints, which requires high assembly, otherwise it will easily cause poor coordination and affect the transmission effect ; Third, the main circuit needs to be provided with insulators for electrical isolation, and it needs to rotate or rotate plus translation to realize the opening and closing action, making its structure complex, transmission loss large and occupying a large space

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.
