Abstract

The invention belongs to the technical field of circuit breakers, in particular to a gravity electromagnetic breaker. In order to solve the problem that a permanent magnet of a magnetic circuit breaker is easy to lose magnetism and cause failure, the circuit breaker comprises a box body, a baffle plate is adhered to the middle part of the box body; a first through hole is formed in the middle of the baffle, the baffle is rotationally connected with an insulator through a rotating shaft at the first through hole, iron blocks are bonded to the two sides of one end of the insulator, an iron coreis bonded to the bottom end of the box body, the iron core is sleeved with a coil, a heat conduction column is arranged at the other end of the insulator, and balancing weights are arranged on the twosides of one end of the heat conduction column. When the coil is powered on, the iron block is attracted, the iron block drives the insulator to rotate, the two elastic pieces are connected, the device is closed, and when the coil is powered off, due to the gravity effect, the two elastic pieces are disconnected, the device is disconnected, the gravity effect is utilized, a permanent magnet is replaced, and device faults caused by instability of the permanent magnet are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a gravity electromagnetic circuit breaker. Background technique [0002] A circuit breaker is a common basic electrical component. Existing electromagnetic circuit breakers are closed by permanent magnets. However, permanent magnets tend to lose their magnetism in high-temperature environments or under collision conditions, resulting in failure of the circuit breaker. [0003] After searching, the Chinese patent application number is 201910359057.3, which discloses a circuit breaker, including a housing and a rotating roller that rotates on the housing and is arranged through the housing; one end of the rotating shaft is fixed with a The triangular block abutted by the magnet is provided with two electromagnet assemblies at the upper and lower ends of the magnet respectively, and the upper electromagnet assembly is used to repel the magnet downward. A circuit breaker in...
