A high-voltage circuit breaker with self-locking function

Abstract

The invention discloses a high-voltage circuit breaker with a self-locking function and relates to the technical field of circuit breakers. When the voltage output by a transformer is too large, the magnetism of an iron core is enhanced, the iron core adsorbs a sliding block to move upwards, the sliding block drives a second push head to move upwards to drive a rotating rod to rotate anticlockwise, and the rotating rod clamps a first push head through a first push groove to drive a sliding plate to move downwards so as to separate a first contact and a second contact, so circuit breaking is achieved. The sliding plate drives a fixing plate to move downwards, and when the fixing hole moves to be flush with an inserting rod, the inserting rod is inserted into the fixing hole to fix the fixing plate, so the self-locking function is achieved. During unlocking, a pull rod is pushed upwards to drive a turntable to rotate, and the turntable drives a connecting rod and the inserting rod to move leftwards, so the inserting rod and the fixing hole are separated and return to a normal state. Manual unlocking is needed during unlocking, so the transformer is prevented from being still in an overlarge output voltage state after automatic unlocking and the practical safety is ensured. The action response is quick, the reliability is high, the structure is simple, the manufacturing cost is low, the use is convenient, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a high-voltage circuit breaker with a self-locking function. Background technique [0002] High voltage circuit breaker plays a control role in high voltage circuit and is one of the important electrical components in high voltage circuit. High-voltage circuit breakers are special electrical appliances that switch on or off high-voltage circuits under normal or fault conditions. [0003] However, the existing high-voltage circuit breaker has poor stability during use, cannot make the circuit more stable, and is prone to the situation of circuit breaker switching, thus reducing the safety of the use of the circuit breaker. Therefore, we propose an automatic circuit breaker. High voltage circuit breaker with lock function. Contents of the invention [0004] The purpose of the present invention is to provide a high-voltage circuit breaker with self-locking function, so ...
