Abstract

The invention provides a small high-voltage cabinet grounding chain mechanism, which comprises an upper side bracket, a lower side bracket, a left side bracket, an upper side connecting crank arm, a locking crank arm, a left side connecting crank arm, a vertical guiding slide plate and a horizontal guiding slide plate. When the horizontal guide slide slides to the left, the free end of the lockingcrank arm rotates upward and protrudes above the circuit breaker handcart track; when the horizontal guide slide slides to the right, the free end of the locking crank arm rotates downward and retracts below the circuit breaker handcart track. The small-sized high-voltage cabinet grounding chain mechanism provided by the invention can realize locking and unlocking of the circuit breaker handcartaccording to the opening and closing state of the grounding knife, thereby preventing an overhaul personnel from accidentally operating and causing an electric shock accident.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a grounding interlocking mechanism for a small high-voltage cabinet. Background technique [0002] With the continuous development of my country's electric power industry, the demand for power transmission equipment continues to increase. High-voltage switchgear is a commonly used power transmission and distribution equipment. There is a circuit breaker handcart inside the high-voltage switchgear, and the circuit breaker handcart moves in the high-voltage switchgear and performs various operations. The high-voltage cabinet is equipped with a grounding knife. When the grounding knife is opened, the high-voltage cabinet is disconnected from the earth. And when the grounding knife is closed, the high-voltage cabinet is short-circuited with the ground. [0003] The purpose of the present invention is to provide a small-sized high-voltage cabinet grounding interlock mechanism, whic...
