A household intelligent circuit breaker

Abstract

The invention discloses a household intelligent circuit breaker. The household intelligent circuit breaker includes an operating system, an electromagnetic system, and a tripping system. The operating system includes a push rod, one end of the push rod is connected with a handle, and the other end of the push rod is hinged to one end of a lock catch connecting rod of the tripping system; the push rod is in contact with the top of a tripping rod of the tripping system, and the tripping rod is vertically connected with a fixed shaft of the tripping rod. The electromagnetic system includes an iron core, a magnet yoke and a coil, the coil is placed in a U-shaped cavity of the magnet yoke and wound on the iron core and an armature, the armature is fixed to an inner wall of one side of the U-shaped cavity, a static contact is fixed under the one side of the U-shaped cavity, and the other side of the U-shaped cavity is fixedly connected with a wiring board; the iron core is fixed in a U-shaped cavity of the armature in a relative position, one end of a spring stretches into an inner cavity of the iron core and is fixedly connected with an inner wall of one end of the iron core, and the other end of the spring stretches into an inner cavity of the armature and is fixedly connected with an inner wall of one end of the armature; and an ejector rod stretches into the inner cavity of the armature and the inner cavity of the iron core. The household intelligent circuit breaker in the invention has two-stage short circuit and overload protection functions, and has high on-off capability.

Description

technical field [0001] The invention relates to a circuit breaker, in particular to a household intelligent circuit breaker. Background technique [0002] At present, small circuit breakers are ubiquitous and have low on-off capacity. At the same time, it is difficult to ensure that in the use of capacitive loads in mass production, contact adhesion occurs from time to time; the tripping force varies from time to time, resulting in unstable product performance. The copper used Large material, high cost and other defects. [0003] The protection method adopted in the so-called "intelligent circuit breaker" that appears on the market at present is: when the electronic circuit detects the passage of the limit impact current, then use the automatic control method to cut off the power supply, but when the electronic circuit or the automatic control system fails, the short circuit protection will be lost. effect. Such "smart circuit breakers" simply cannot meet international cir...
