Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
Fig. 1 is the current setting of Thermomagetic circuit-breaker at varying environment temperature; Fig. 2 be variation of ambient temperature appearance coefficient falls; Explanation is under different ambient temperatures, and the operating current of Thermomagetic circuit-breaker need to be adjusted.
Referring to Fig. 3, Pyromagnetic release of the present utility model comprises housing 1, hot guard block, magnetic guard block, thermal compensation bimetal leaf 3, snap device 4 and release lever 5.
Referring to Fig. 4, hot guard block comprises thermal element 23, thrermostatic bimetal-plate 24 and thrermostatic bimetal-plate cap 25.
Magnetic guard block comprises static gag bit 22 and the moving armature assembly 21 corresponding with static gag bit.
The structure of thermal and magnetic guard block is consistent with traditional Pyromagnetic release, and thermal characteristics protection is all to promote release lever 5 by thrermostatic bimetal-plate cap 25, and the snap device 4 of Pyromagnetic release is triped, and realizes the protection of circuit breaker.
Referring to Fig. 5, thermal compensation bimetal leaf 3 one end are fixed on housing 1, and the other end and release lever 5 are that linkage structure is subject to the impact of ambient temperature and bending, when thermal compensation bimetal leaf 3 deforms bending, can promote release lever 5 horizontal slips.
Release lever 5 is arranged on housing 1 by release lever axle 6, and release lever 5 can carry out horizontal slip and rotation on release lever axle 6.
Bimetal leaf cap 25 is enclosed within above thrermostatic bimetal-plate 24, and along with thrermostatic bimetal-plate 24 is out of shape, move to certain phase and just can contact with release lever 5, more further motion, bimetal leaf cap 25 just can promote release lever 5 and rotate.
