Abstract

The invention provides an intelligent circuit breaker, which comprises a housing, a first wiring end, a second wiring end, a handle, a tripping linkage mechanism, an electromagnetic tripper, a movingcontact, a static contact, a bimetal sheet, a current transformer, a drive mechanism, a first driving member, a second driving member, a first connecting member, a second connecting member and a circuit board. The moving contact is corresponding to the static contact. The intelligent circuit breaker can solve the problem that a traditional circuit breaker is poor in protection precision and incomplete in protection, realizes a distribution protection function and meanwhile, realizes intelligent control of the intelligent circuit breaker, can carry out on/off control according to power demand,and can also realize local or remote centralized monitoring management, thereby improving power distribution safety and intelligence degree.

Description

technical field [0001] The invention belongs to the technical field of electric power equipment, and in particular relates to an intelligent circuit breaker. Background technique [0002] Circuit breakers are switching devices used in power distribution systems to cut off circuits when overload or short-circuit faults occur. They are widely used in power distribution places such as industry, commerce and residential buildings. Circuit breakers can no longer meet the current needs, including the need for manual control, which is not convenient for on-off control, and is not suitable for intelligent control of power distribution on-off; and traditional circuit breakers have physical characteristics due to their own electromagnetic trippers and bimetallic strips. There are also problems such as high discreteness, poor protection accuracy and incomplete power distribution protection functions, which make the power distribution system still have potential safety hazards. In view...
