Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention relates to a modularized circuit breaker, including a circuit breaking module, the circuit breaking module includes a casing 1, the inside of the casing 1 is provided with a structure the same as the inside of the existing circuit breaker, but the inside of the circuit breaking module is only a circuit breaking structure of one phase circuit, the specific structure is not repeated, but the voltage that the internal structure can bear needs to be 380V or more, the middle part of the front end of the casing 1 is provided with a shifting block 2, the shifting block 2 is shifted upwards, the circuit is switched on, the shifting block 2 is shifted downwards, the circuit is switched off, the inside of the shifting block 2 is provided with a through hole 6, the middle part of the through hole 6 is provided with a stop 7, a connecting strip 8 is installed between every two shifting blocks 2 and respectively extends into the through hole 6, the shifting blocks 2 of two circuit breaking modules can be connected through the connecting strip 8, make the module that opens circuit open simultaneously or close, every connecting strip 8's inside all is provided with reinforcing strip 9, every reinforcing strip 9 is the metal material, can increase connecting strip 8's rigidity, both ends all are provided with wiring mouth 3 at the bottom of the top of casing 1, be used for the electric wire that connects, only connect a looks electric wire on every module that opens circuit, be provided with several installation piece 4 and several mounting groove 5 on casing 1,

installation piece

4 and 5 phase-matchs of mounting groove, several installation piece 4 sets up respectively in casing 1's left end four corners department and casing 1's front end four corners department, mounting groove 5 sets up respectively in casing 1's right-hand member four corners department and casing 1's rear end four corners department, the module that opens circuit is the several, and be connected the installation through several installation piece 4 and mounting groove 5, the equipment of module that opens circuit through the several, thereby form this circuit breaker.
