AI Technical Summary

Problems solved by technology

Fault phenomena such as false opening, false closing, refusal to open, refusal to close, inadequate opening and closing, and automatic tripping that are prone to occur in circuit breakers are all caused by mechanical failures in the operating mechanism of the circuit breaker.
To sum up, there are still many imperfections in the opening and closing control mechanisms of circuit breakers used by various switchgears, which lead to potential safety hazards in the operation of power grids and power transmission and distribution equipment.

Abstract

The invention discloses a breaker switching-on-off operating device and belongs to the technical field of breakers. A powered motor (22) drives a bevel gear pair (36) through an output shaft of the gear box (21). The bevel gear pair drives a ball screw to rotate and drives a ball nut component (7) to move downwards and linearly. Rotary motion in the prior art is changed into linear motion. The ball nut component drives a slider combination (39) to accumulate energy. The commonly used crankshaft connecting rod drive mechanism is replaced by a switching-on-off mechanism. Part number is lowered to a quarter of that of the breaker with the crankshaft connecting rod mechanism, and fault probability of the operating mechanism is lowered effectively. Faults such as false switching-off, false switching-on, switching-off refusing, switching-on refusing, not-in-place switching-on-off and automatic disconnection of the breaker are prevented, and switching-on-off performance of the breaker are increased.

Description

technical field [0001] The invention relates to a circuit breaker, in particular to a circuit breaker opening and closing control device, which belongs to the technical field of circuit breakers. Background technique [0002] The circuit breaker opening and closing operating mechanism is a key component of all kinds of power switching equipment. The action process of the circuit breaker operating mechanism includes energy storage, closing and opening. The circuit breaker can only perform closing operation after energy storage. Therefore , The energy storage and opening and closing operating mechanism in the circuit breaker play a very important role in the power switchgear. If the energy storage operating mechanism fails, it will seriously affect the opening and closing performance of the circuit breaker. [0003] At present, the spring crankshaft connecting rod operating mechanism commonly used in various circuit breakers uses the crankshaft connecting rod operating mechani...
