Embodiment
In conjunction with Fig. 1, power supply has two fuses in the loop between the lamp load, and we are these two fuse called after JZ220 fuses, JF220 fuse, and the some lamp load all will cut off the power supply behind any one fuse failure wherein.
In conjunction with Fig. 2, fuse redundant apparatus circuit of the present utility model does not affect the normal operation of circuit when main fuse is normal, machinery homing relay coil gets electric picking up when main fuse fuses, and secondary fuse is connected in the action of contact group, light simultaneously alarm lamp, and the output alarm condition.Get the electric time that picks up through test mechanical homing relay coil, both can tide over the moment overload of inductive load, the situation of fusing of again transshipping when avoiding secondary fuse to connect occurs, and is again can the time not oversize, and causes the semaphore outage to close.The time range of mechanical reset relay energized is 70 ~ 150ms.
In actual use after mechanical reset relay energized alarm lamp is lighted, need to change first the main fuse of fusing, after replacing is finished, manually press carriage return button, remove and report to the police, make the mechanical reset relay reset continue the state of real-time oversight main fuse.
Fuse redundant apparatus workflow of the present utility model is:
1) state of mechanical reset relay real-time oversight main fuse at first;
2) machinery homing relay coil gets electric picking up when main fuse fuses, and secondary fuse is connected in the action of contact group, lights simultaneously alarm lamp, and the output alarm condition;
3) change the main fuse that fuses;
4) manually press carriage return button, remove and report to the police, make the mechanical reset relay reset continue the state of real-time oversight main fuse.
As from the foregoing, the utility model is the state by mechanical reset relay real-time oversight main fuse, and machinery homing relay coil gets electric picking up when main fuse fuses, the action of contact group, connect secondary fuse, light simultaneously alarm lamp, and the output alarm condition.
Light when discovery main fuse alarm lamp, must at first change the main fuse that has fused, then just can manually press carriage return button, remove and report to the police, restore mechanical homing relay.
When finding that major-minor fuse alarm indicator light is all lighted, must at first change two fuses of major-minor that fused, then just can manually press carriage return button, remove and report to the police, restore mechanical homing relay.
In conjunction with Fig. 3, because power supply has two fuses in the loop between the lamp load, the some lamp load all will cut off the power supply behind any one fuse failure wherein.In order to prevent two any one fuse failures of fuse in the loop, cause the situation of load outage to occur, supervise respectively two fuses in the loop with two mechanical reset relays, and spare fuse is set separately works alone, it is perfectly safe to accomplish like this.
The identical fully independently two covers power fuse redundant apparatus of lighting a lamp is supported for the loop that lights a lamp provides redundant.
