An electrical switch insulation device

Abstract

The invention discloses a novel electrical switch insulation device, comprising an insulating cover and an active contact base, wherein the insulating cover is fixedly arranged on the outer surface of the active contact base, a wiring trough is fixedly arranged inside the active contact base, a flexible connecting wire is arranged inside the wiring trough, an active contact is bridged at the upper end of the wiring trough through an insulator, a contact pressure spring is fixedly arranged inside the active contact, a moving arc contact is arranged in a shaft of the contact pressure spring, a static contact base is arranged at the right end of the active contact base in parallel, a connecting arc tube is arranged inside the static contact base, a static arc contact is fixedly arranged at the right end of the connecting arc tube, the electric charge is exported or directly grounded through the flexible connecting wire, and thus the moving arc contact is disconnected from the static arc contact to achieve the purpose of power failure, high-voltage damages of the insulating cover can be prevented, the service life of the insulation device can be prolonged, and the strong practicability can be achieved.

Description

technical field [0001] The invention relates to the technical field of electrical switches, in particular to an insulating device for electrical switches. Background technique [0002] Due to the limitations of the existing insulation design theory and the dispersion of insulating materials, whether the insulation of high-voltage electrical equipment designed and developed can meet the technical and standard requirements requires strict inspection by high-voltage insulation tests. The erosion of various unfavorable natural environments, the long-term effect of working voltage, and the short-term impact of internal and external overvoltages during the insulation operation of the equipment will cause the gradual aging and deterioration of the insulation, resulting in a reduction in the service life of the insulation device. Moreover, in the wiring layout More and more switch insulation devices are used, and they must be completely insulated during the on-off process of the lin...

Problems solved by technology

The erosion of various unfavorable natural environments, the long-term effect of working voltage, and the short-term impact of internal and external overvoltages during the insulation operation of the equipment will cause the gradual aging and deterioration of the insulation, resulting in a reduction in the service life of the insulation device. Moreover, in the wiring layout More and more switch insulation devices are used, and they must be completely insulated during the on-off process of the line to prevent leakage and other phenomena. The traditional switch insulation device has certain defects in the high-voltage resistance. If the particles adhere to the surface of the insulator, the threat to the insulation will be greater, making the safety performance of the switch insulation device lower
