Problems solved by technology

The attraction of the electromagnet needs to be realized through the control of the electronic product. The structure of the circuit breaker in the prior art is complicated. After being assembled with the electronic product, there are many lines, many fault points, and the volume is also large, so that it is difficult to maintain and check the fault. , it is cumbersome to replace the circuit breaker or components, and it is even more difficult to integrate and separate the vacuum tube and the main circuit

Abstract

The invention relates to the field of circuit breakers, and particularly discloses a modular permanent-magnetic circuit breaker which comprises a shell. Three containing cavities are sequentially arranged in the shell from top to bottom, a vacuum pipe and a permanent-magnetic device are arranged in each containing cavity, a moving contact and a static contact are oppositely arranged inside each vacuum pipe, a rod portion of each moving contact extends out of one outer side of the corresponding vacuum pipe and is connected with the corresponding permanent-magnetic device through a connecting mechanism, a rod portion of each static contact extends out of the other outer side of the corresponding vacuum pipe and extends to one outer side of the shell to serve as an input end of the corresponding vacuum pipe, a current transformer is arranged on the rod portion, positioned in the corresponding containing cavity, of each moving contact, an electroconductive block is connected on the rod portion, extending out of the outer side of the corresponding vacuum pipe, of each moving contact and connected with an output end of the corresponding vacuum pipe through an electromagnetic band, and the output end of each vacuum pipe extends to the outer side of the shell on the same side with the input end of the corresponding vacuum pipe. The circuit breaker is modular and has the advantages of small size, simple structure, convenience in maintaining and replacing and easiness in trouble spot checking.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a modular permanent magnet circuit breaker. Background technique [0002] A circuit breaker refers to a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time, and protect power lines and motors. , When they have severe overload or short circuit and undervoltage faults, they can automatically cut off the circuit. Its function is equivalent to the combination of fuse switch and overheating relay. Moreover, there is generally no need to change parts after breaking the fault current. At present, it has been widely used. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The division of high and low voltage boundaries is relatively vague. Generally, those above 3kV a...
