Problems solved by technology

However, these are in the form of mechanical tripping mechanisms and mechanical operating mechanisms, and neither can achieve control
In the era of intelligent research on electrical appliances, these cannot meet the requirements of production development, or their performance indicators cannot achieve a leap
These solutions can only be applied to ordinary circuit breakers, not to intelligent circuit breakers, let alone intelligent integrated appliances

Abstract

The invention relates to an electrical appliance rapid breaking action mechanism which is based on current excitation of a main circuit, the electrical appliance rapid breaking action mechanism comprises a moving contact bridge, a moving contact, a static contact, a static contact bridge, a moving iron core, a current excitation static iron core, a current excitation coil of the main circuit, a current transformer, a current excitation control circuit, a computer control system and a support; when the rapid breaking action of an electrical appliance is required, the computer control system is used for control, the current of the main circuit is introduced into the current excitation coil of the main circuit via the current transformer and the current excitation control circuit, and the moving iron core drives the moving contact to rapid open and break the circuit under the action of the electromagnetic attraction, thereby ensuring the high breaking capacity of the electrical appliance, high electrical service life and reliable operation.

Description

technical field [0001] The invention relates to the technical field of low-voltage electrical appliances, in particular to an electrical quick breaking action mechanism based on main circuit current excitation. Background technique [0002] The utility model patent "Fault Current Quick Release Mechanism of Circuit Breaker" (CN2785124Y) filed by Xu Bo et al. introduces a fault current quick release mechanism of circuit breaker, including jumpers, locks, and drawbars, and also includes: A static iron core is installed below the drawbar; a moving iron core is fixedly connected to the lower end of the drawbar and opposite to the static iron core; a conductive plate is located near the static iron core. When a large fault current passes through the conductive plate, the nearby static iron core generates magnetic force, attracting the moving iron core to move downward, and the draw bar connected with the moving iron core makes the operating mechanism release quickly to achieve the...
