Problems solved by technology

When installing, first place the release body on the transformer seat, then cover the circuit breaker shell, and fix it with screws. This operation has a big disadvantage, that is, the release and the mutual inductor The seat is not fixed, it is easy to cause looseness and cause the dislocation of the release. If it is found in time, then the release needs to be reinstalled. If it is not found in time, the release will not be reset during use, which will affect the overall circuit. usage of

Embodiment 1

[0025] A circuit breaker, the structure of which is as follows figure 1 As shown, the circuit breaker includes a base 1, a transformer 2 fixedly installed on the base 1, three releases 3 fixedly installed on the base 1 and the transformer 2, and a circuit board (the circuit board is not shown in the figure reflected in).

[0026] Among them, the release structure is as follows figure 2 As shown, the release 3 includes a base plate 31 and a release body 34 fixed on the base plate 31 . Two buckles are provided on the side of the base plate 31 and are connected to the transformer 2 and the base 1 through the buckles.

[0027] The buckle includes a T-shaped buckle 32 and an L-shaped buckle 33. The top of the vertical side of the T-shaped buckle 32 is connected to one side of the bottom plate 31, and the vertical side of the L-shaped buckle 33 is connected to one side of the bottom plate 31. .

[0028] The two planes of the T-shaped buckle 32 are respectively flush with the two...

Abstract

The invention relates to a circuit breaker. The circuit breaker comprises a base, a mutual inductor, a plurality of trippers and a circuit board, wherein the mutual inductor is fixedly arranged on the base, the plurality of trippers are fixedly arranged on the base and the mutual inductor, each tripper comprises a bottom plate and a tripper body, the tripper body is fixed on the bottom plate, a plurality of buckles are arranged at a side edge of the bottom plate, and the bottom plate is connected with the mutual inductor and the base by the buckles. Compared with the prior art, T-shaped buckles and L-shaped buckles are arranged, the trippers can be effectively fixed on the base, and a risk brought by incorrect installation of the trippers is avoided.

Description

technical field [0001] The invention relates to the field of power distribution, in particular to a circuit breaker. Background technique [0002] The circuit breaker is generally equipped with a release device, which is used to release the holding mechanism and automatically disconnect the circuit breaker. The current release generally adopts a plastic shell, which is fixed on the transformer seat by a screw. When installing, first place the release body on the transformer seat, then cover the circuit breaker shell and fix it with screws. This operation has a big disadvantage, that is, the release and the mutual inductor If the device seat is not fixed, it is easy to cause looseness and cause the release to be misplaced. If it is found in time, then the release device needs to be reinstalled. If it is not found in time, the release device will not be able to reset during use, which will affect the overall circuit. usage of. Contents of the invention [0003] The object...
