Interlocking mechanism of electrical safety grounding switch

Abstract

The invention discloses an interlocking mechanism of an electrical safety grounding switch, and the interlocking mechanism comprises a shell; a setting cavity is arranged in the shell, a motor is fixedly arranged on the inner wall of the rear side of the setting cavity, the upper end surface of the motor is in driving connection with a driving shaft, the driving shaft is rotatably connected to the upper end surface of the setting cavity, and the driving shaft is fixedly connected with a first belt pulley. According to the interlocking mechanism, interlocking control over the grounding switch is achieved through the unchangeable physical properties of an object such as buoyancy and the coefficient of thermal expansion, common gear or connecting rod transmission and the like are not used, the situation that the interlocking mechanism cannot be used due to common abrasion is avoided, and the service life of the interlocking mechanism is greatly prolonged; moreover, the used hydraulic part is in a low-pressure state, so that the leakage problem is avoided, and the interlocking reaction speed is high due to the lubrication effect of the hydraulic part.

Description

technical field [0001] The invention relates to the technical field of grounding switches, in particular to an interlock mechanism of an electrical safety grounding switch. Background technique [0002] The grounding switch refers to a mechanical grounding device that releases the static electricity of the equipment and circuits under maintenance and ensures the personal safety of the maintenance personnel during power outage maintenance. Most of the grounding switches have the characteristics of both manual and electric operation. Operation, there is usually an interlock mechanism, but most of the existing interlock mechanisms are realized through mechanical transmission, the structure is relatively complicated, and there will be wear and tear when the mechanical transmission is used. When the wear exceeds a certain level, the interlock will be It will fail, causing potential safety hazards, and because the operating force is too large, it is easy to deform the interlocking...
