Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
As Fig. 4, it is the schematic diagram that new electromagnetic lock in the present invention connects high pressure and detect circuit, a kind of high electricity-saving magnetic padlock of high voltage power distributing cabinet, comprise: band Electrical key 1, unlock circuit 2, high pressure detect circuit 3 and high pressure sensor 4, the output terminal of described high pressure sensor 4 is connected to described high pressure and detects the input end of circuit 3, and described high pressure identification loop 5 is connected in described high pressure and detects between the output terminal of circuit 3 and the output terminal of described unlock circuit 2;
The input end of described unlock circuit 2 is made up of the keyhole 21 of mutually connecting, lockset coil 22 and lockset 23, describedly inserts in the keyhole 21 of described unlock circuit 2 input ends with Electrical key 1;
Described high pressure identification loop 5 comprises: controllable silicon 51, relay 52 and triode 53;
The anode of described controllable silicon 51 is connected with the collector of described triode 53, the negative electrode of described controllable silicon 51 is connected with the lockset 23 of described unlock circuit 2, the control utmost point of described controllable silicon 51 is connected to described high pressure and detects the output terminal of circuit 3, the negative pole of described relay 52 is connected with the base stage of described triode 53, its positive pole is connected with described keyhole 21, and the emitter of described triode 53 is connected with the lockset of described unlock circuit 2;
