Abstract

The invention relates to a high voltage relief switch, which is characterized by comprising a fixing board, a support is arranged at the lower end of the fixing board, an electromagnet coil is arranged on the support, a first high voltage contact and a second high voltage contact are arranged at the top end of the fixing board, and a traction component is arranged below the first high voltage contact and the second high voltage contact; the traction component comprises a blocking board, an electromagnet column is arranged on the lower end face of the blocking board, a connecting rod is arranged on the upper end face of the blocking board, an upper end of the connecting rod is connected with a short circuit board which is arranged below the first high voltage contact and the second high voltage contact; a spring is sleeved on the electromagnet column, an upper end of the spring is fixedly connected with a fixing ring, a lower end of the spring is fixedly connected with a gasket, and the gasket is fixed at the upper end of the support; and a power module is arranged on the fixing board on the other side of the electromagnet coil. The high voltage relief switch can relieve surplus high voltage more effectively and rapidly in condition that high voltage power-supply devices power off suddenly, so that safety of circuits and personnel is guaranteed.

Description

technical field [0001] The invention relates to a high-pressure relief switch, in particular to a relief switch for releasing residual high pressure. Background technique [0002] The high-voltage release switch is a device used to release the remaining high voltage in the case of a sudden power failure of the high-voltage power supply equipment, which can ensure the safety of the line and personnel. Most of the existing high-voltage power supply discharge devices are large in size, and their stability and sensitivity are not very high. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a high-pressure relief switch with small volume, stable performance and high sensitivity. [0004] According to the technical solution provided by the present invention, the high-voltage relief switch is characterized in that it includes a fixed plate, a bracket is installed on the lower end of the fixed pla...
