Abstract

The invention discloses a switching device for a high voltage loop. The switching device for the high voltage loop comprises a low voltage end, a high voltage end and a connection unit, wherein the low voltage end is connected to a low voltage loop and is used for receiving a control signal from the low voltage loop; the high voltage loop is switched off or conducted under the control of the control signal; the high voltage end comprises a high voltage end cavity; a gap in the high voltage end cavity is totally filled with a solid insulated filler; the connection unit comprises a first end and a second end; the first end is connected to the low voltage end; the second end is connected to the high voltage end. By the switching device, partial discharge cannot be generated when a switch controls a high voltage power transmission system to carry out safe conduction and switching-off operations.

Description

technical field [0001] The present invention relates to the field of switches, in particular, to a switch device for a high-voltage circuit. Background technique [0002] With the increasing demand for electric power in society, the electric power industry has developed rapidly. The development speed of the electric power industry is restricted by the safety of the transmission system. Therefore, the safe operation of the transmission system has become a major concern of the electric power industry. In order to ensure the safe operation of the power transmission system, the power industry generally conducts regular inspections on power facilities such as the power transmission system. During the detection process, it is often necessary to perform disconnection and turn-on operations on the power transmission system. Since the power transmission system is generally a high-voltage circuit, its on and off operations pose a huge threat to the safety of people and equipment. ...
