Abstract

The invention relates to a circuit breaker with a mechanical resettable flux converter, which is characterized by comprising a lever belonging to a circuit breaker mechanism part, a base of the flux converter on a circuit breaker base, a magnet yoke fixedly connected on the base and a slider capable of sliding in the magnet yoke. A vertical shaft on one side of the lever in the mechanism pushes the slider to move forward to compress a compression spring on the slider until a tripping buckle on the magnet yoke can hook the slider to complete resetting. In the resetting process, the invention reduces resetting power consumption, simplifies intermediate links, enables resetting action to be more stable and reliable and greatly increase the reliability of the product; and moreover, the resetting mechanism occupies smaller space to further reduce the size of the molded case circuit breaker.

Description

technical field [0001] The invention belongs to a circuit breaker, in particular to a circuit breaker with a mechanically resettable magnetic flux converter which can be mechanically reset when the circuit breaker is closed by a handle. Background technique [0002] With the rapid and extensive application of electronic technology in the field of low-voltage electrical appliances, the intelligent circuit breaker is a new type of circuit breaker born in response to market demand. Its intelligent protection function, miniaturization, modular structure and accessories are inevitable development trends. At present, the resetting method of the magnetic flux converter of the known plastic case circuit breaker is to hit the rotary plate in the large bracket by the handle during the re-clamping process, and the rotary plate drives the supporting plate to rotate. The supporting plate collides with the moving iron core of the magnetic flux converter again to make it attract and reset....
