The magnetic conductive plate and the lower flash barrier are arranged below the right of the base, and the static contact component is arranged on the right side of the base; the electromagnetic system is arranged on the base, the wiring board of the electromagnetic system and the static contact are arranged at the left middle part of the base, a coil and a bracket are arranged in the middle of the base, the moving contact is arranged on the right upper side of the base, a casing is mounted on the electromagnetic system, and the wiring board of the electromagnetic system, the static contact, the coil, a bracket component and the moving contact are arranged inside the casing; the lock catch is arranged on the left upper side of the base, and the jumping latch is arranged at the middle upper part of the base; the arc extinguish chamber is arranged at the middle lower part of the base, and the rear flash barrier is arranged on the left side of the arc extinguish chamber; and the magnetic conductive sheet is arranged on the left side of an iron core of the electromagnetic system. The moving contact can be rapidly closed. The high-breaking small-sized circuit breaker has high breaking capacity, and can ensure the safe operation of a system.
Description
Technical field:
The utility model relates to a kind of low-voltage circuit breaker, is specifically related to a kind of high breaking miniature circuit breaker.
Background technology:
Low-voltage circuit breaker is a kind of important protection electrical equipment, and when faults such as the serious overload of circuit generation, short circuit, the disengagement failure circuit is effectively protected the electric equipment that is connected on its back automatically.The electromagnetic system that low-voltage circuit breaker generally has moving contact and the arc quenching system of carrying out on-off circuit, experience the circuit abnormal state has reached the trip free of intermediate transfer effect and operating mechanism etc.Existing miniature circuit breaker is when hand-reset, and the moving contact closing speed depends on hand propelled handle velocity of rotation, and moving contact pressure is to start from scratch slowly to increase, and this can cause and draw electric arc, thereby influence the useful life of contact; In addition, the electromagnetic system poor sealing of existing most of miniature circuit breakers is not sealed in the housing fully, causes safety failure easily.
The utility model content:
Technical deficiency at existing the said goods, the purpose of this utility model is to provide a kind of high breaking miniature circuit breaker, and it is made up of back flash barrier, arc control device, pedestal, magnetic conduction sheet, electromagnetic system, terminal block, moving contact, snap close, tripping, following flash barrier, fixed contact assembly, magnetic conductive board etc.
The technical scheme that its technical problem that solves the utility model adopts is: the pedestal lower right is provided with magnetic conductive board and following flash barrier, and the fixed contact component placement is on the pedestal right side; Electromagnetic system is placed on the pedestal, the terminal block of electromagnetic system and fixed contact are placed in the middle part, a left side of pedestal, coil, support are placed in the pedestal middle part, moving contact is placed in the pedestal upper right side, housing is installed on the electromagnetic system, and the terminal block of electromagnetic system, fixed contact, coil and bracket component, moving contact are placed in enclosure interior; Snap close is placed in the upper left side of pedestal, and tripping is placed in the middle and upper part of pedestal; The middle and lower part of pedestal is provided with arc control device, and back flash barrier is placed in the left side of arc control device; Magnetic conduction sheet is placed in the left side of electromagnetic system iron core.
The beneficial effects of the utility model are: the quick-make of moving contact energy, be not subjected to the influence of manual speed speed, and have high breaking capacity; Conductive component all is sealed in the housing, the safe operation of safeguards system.
