Abstract
The utility model discloses a novel thermo-magnetic system device of a miniature circuit breaker, comprising a duplex metal tripping mechanism (1) and an electromagnetic tripping mechanism (2), wherein the duplex metal tripping mechanism (1) is separately fixed on a circuit breaker supporting part (4); the electromagnetic tripping mechanism (2) is separately fixed on a magnet yoke (3) of an electromagnetic tripping device; and the magnet yoke (3) of the electromagnetic tripping device takes on a U shape, and a semi-closed state is formed for an electromagnetic coil. The novel thermo-magnetic system device has the advantages that in the working process of an electromagnetic mechanism, the air gap between the magnet yoke and a mixing and a fixed iron cores can be reduced, a magnetic force line can be ensured to be better aggregated, flux leakage hardly occurs, better efficiency and reliability can be obtained when in work.
Description
Technical field
The utility model relates to a kind of pyromagnetic system of miniature circuit breaker, the pyromagnetic system of particularly a kind of DZ47 series and similar miniature circuit breaker.
Background technology
The hot tripping system of existing DZ47 series miniature circuit breaker and electromagnetic trip system are common to use one to support A, promptly as the supporter of hot tripping system, use as a part of yoke of electromagnetic trip system again, and other a part of yoke only is a small iron plate that is not connected therewith, thereby causes magnetictrip because of the not high shortcoming of the reason operating efficiency of leakage field and air reluctance.
Summary of the invention
At the shortcoming of existing miniature circuit breaker, the utility model provides a kind of pyromagnetic system of novel miniature circuit breaker.
To achieve these goals, the measure taked of the utility model:
A kind of pyromagnetic system of novel miniature circuit breaker comprises thermo bimetal's tripping mechanism, electromagnetic trip mechanism, and described bimetallic tripping mechanism is fixed in separately on the circuit breaker supporter; Electromagnetic trip mechanism is fixed in separately on the yoke of magnetictrip;
The yoke of described magnetictrip is the U font, and solenoid is formed a semi-closed state.
The beneficial effects of the utility model: in the process of electromagnetic mechanism work, reduce the air gap between yoke and the sound iron core, the magnetic line of force is more assembled, leakage field still less just has better efficient and reliability in the time of work.
Description of drawings
Fig. 1, structural representation of the present utility model.
Fig. 2, the magnetic line of force path schematic diagram during work of the utility model electromagnetic mechanism.
Embodiment
A kind of pyromagnetic system of novel miniature circuit breaker as shown in Figure 1, comprises thermo bimetal's tripping mechanism 1, electromagnetic trip mechanism 2, and described bimetallic tripping mechanism 1 is fixed in separately on the circuit breaker supporter 4; Electromagnetic trip mechanism 2 is fixed in separately on the yoke 3 of magnetictrip; In the pyromagnetic system acting process of circuit breaker, bimetal leaf lower end on thermo bimetal's tripping mechanism 1 is fixed on the supporter 4, the upper end will be out of shape according to the size and the length of time of electric current, and when being deformed to a certain degree, the locking mechanism that promotes thermo bimetal's tripping mechanism 1 is threaded off; When electric current passes through coil, as shown in Figure 2, the acting magnetic line of force 5 that coil produces forms the loop by moving iron core → yoke → static iron core → sound iron core air gap, to attract to the static iron core direction less than fixing moving iron core, when electric current reaches the value that presets, the counter-force that attraction will overcome spring will be moved iron core and be attracted to moving iron core direction, also push rod be promoted simultaneously, and the locking mechanism of electromagnetic trip mechanism 2 is threaded off.
Those skilled in the art's simple change and replacement all are within the protection range of the present utility model in this area.
Claims (2)
