The utlity model has following beneficial effect: the utility model is simple and practical, by mechanical interlocking and electromagnetic lock duplicate protection, prevents charged misoperation, guarantees equipment safety operation and staff's personal safety.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, 1, door lock, 2, chain pressing plate, 3, observation window, 4, indicator light, 5, the control power line, 6, the earth connection of moving into one's husband's household upon marriage, 7, isolating switch, 8, deciliter indication, 9, charged locking is chain, and 10, close the door locking in flakes, 11, close badge rail pressure plate, 12, operating grip, 13, charged locking electromagnetic lock, 14, binding post, 15, spiral Wire crimping cap, 16, chamber door, 17, casing.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated
As shown in Figure 1, the isolated operation case, comprise casing 17, chamber door 16, mechanism's interlocking part, indicator light 4, operating grip 12, described chamber door 16 is provided with observation window 3, observation window 3 belows are provided with indicator light 4, chamber door 16 edges are provided with door lock 1 and chain pressing plate 2, casing 17 is provided with operating grip 12, be provided with isolating switch 7 in the casing 17, one end of isolating switch 7 is connected with indicator light 4 by control power line 5, the other end connects a plurality of binding posts 14 respectively, mechanism's interlocking part comprises charged locking chain 9, the locking in flakes 10 of closing the door, close badge rail pressure plate 11, be connected with charged locking electromagnetic lock 13 in the charged locking chain 9, isolating switch 7 is connected with charged locking chain 9, close badge rail pressure plate 11 and 10 be connected with charged locking chain 9 in flakes by the locking of closing the door, casing 17 bottoms are provided with spiral Wire crimping cap 15, are connected with the earth connection 6 of moving into one's husband's household upon marriage between casing 17 and the chamber door 16.
During normal the operation, the visible isolating switch of control box chamber door observation window is in " closing " position, operating grip is in " closing " position, because locking part and door interlocking, door can't be opened, and indicator light is in bright state, this moment is if there is people's misoperation, because of the electromagnet of charged locking electromagnetic lock adopt be that energising discharges, dead electricity retraction type, electromagnet armature has hindered the action of mechanism's locking part when charged, isolating switch can't separating brake; When needs overhaul, last level power supply has a power failure, the electromagnet armature retraction, no longer hinder the running of interlocking gear, when dividing operating grip, mechanism's interlocking part and gate interlock pressing plate break away from, door can be opened, handle this moment can hang 3 locks simultaneously, guarantee that all maintainers put in place simultaneously to send electricity after the release, also guarantee maintainer's safety simultaneously.
The utility model is not limited to above-mentioned execution mode, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection range of the present utility model.
The technology that the utility model is not described in detail, shape, structure partly are known technology.
