Problems solved by technology

[0004] Most of the existing electromagnetic repulsion mechanisms are coil-disk structures, and the driving efficiency is low; at the same time, frequent high-speed movements have high requirements for the strength of all aspects of the repulsion mechanism, so the life of the repulsion coil is generally limited

Abstract

The invention discloses a non-symmetric repulsion mechanism. The non-symmetric repulsion mechanism comprises a transmission rod, a main quick repulsion unit, an auxiliary quick repulsion unit and a buffer unit. The main quick repulsion unit is composed of a movable repulsion coil and a first fixed repulsion coil. The auxiliary quick repulsion unit is composed of a movable repulsion aluminum plate and a second fixed repulsion coil. The movable repulsion coil and the movable repulsion aluminum plate are fixed to the transmission rod, and the first fixed repulsion coil and the second fixed repulsion coil are fixed to a repulsion mechanism coil mounting plate. The non-symmetric repulsion mechanism makes full use of the characteristic of high efficiency under heavy load of a coil-coil type repulsion structure to improve the driving efficiency of the repulsion mechanism and reduces the collision between the repulsion plate and the repulsion coil as well as between the repulsion coils to prolong the service life of the repulsion mechanism. A user can flexibly choose an opening unit and a closing unit as application occasion required. The non-symmetric repulsion mechanism is simple in structure, quick in movement, high in drive efficiency, long in service life and flexible in operation.

Description

technical field [0001] The invention belongs to the field of repulsion mechanisms, and more specifically relates to an asymmetric repulsion mechanism. Background technique [0002] The circuit breaker is an important switching device in the power system. Because of its irreplaceable control and protection functions in the power system, the reliable operation of the circuit breaker is increasingly important. In view of this situation, the International Conference on Large Power Grids (CIGRE) has conducted several surveys around the world. The survey shows that most of the faults of circuit breakers are mechanical in nature, mainly including their operating mechanisms, monitoring devices, and auxiliary devices. As the voltage level increases, the number of components in the circuit breaker operating mechanism will increase, so the probability of failure will be higher. [0003] Due to the large number of action links and the large cumulative motion tolerance, the traditional ...
