Abstract

A high voltage isolating switch comprises a control module and a switch executing module, wherein the control module is used for having control over the switch executing module, and the switch executing module is used for executing actual on-off operation on a high voltage circuit; the switch executing module comprises an upper supporting frame (12), a lower supporting frame (13), a moving contact (1), a struck contact (2), a first telescopic limiting pin (6), a second telescopic limiting pin (7) and a third telescopic limiting pin (8), the moving contact and the struck contact are connected with two terminals of the high-voltage circuit respectively, and the moving contact (1) and the struck contact (2) are borne by the upper supporting frame (12); the first telescopic limiting pin (6), the second telescopic limiting pin (7) and the third telescopic limiting pin (8) are sequentially arranged in the upper supporting frame from right to left; the upper supporting frame is borne by the lower supporting frame (13) through a supporting porcelain bottle (16).

Description

technical field [0001] The application relates to the field of high-voltage switches, in particular to a high-voltage isolation switch. Background technique [0002] A high-voltage switch is a commonly used switch in the field, and its high-voltage-resistant material and layout design have mature solutions in the field. In order to realize the remote operation of the high voltage switch, a high voltage isolating switch is now available. [0003] Since sparks and arcs are prone to occur in high-voltage lines, the opening and closing actions of high-voltage switches often require a relatively fast speed. However, while the speed is fast, it is often prone to large shock vibrations, which will affect the reliability and safety of electrical equipment. Contents of the invention [0004] The invention provides a control method of a high-voltage isolating switch, which can realize remote high-voltage switch action, and meanwhile has less impact, and is safe and reliable.
