Abstract
The utility model belongs to high voltage electric equipment field, relates to a kind of high-tension electricity magnetic padlock with voice alarm function.It comprises the master switch of power supply, electromagnet and control magnet switching, it also comprises the phonetic alarm device in parallel with electromagnet and the constant open contact of closure in the time sensing high-tension apparatus voltage signal, described constant open contact is connected with phonetic alarm device, controls the break-make of phonetic alarm device.Charged at high-tension apparatus, can not open high-tension apparatus door in the situation that, when electromagnetic lock is operated, can sound and report to the police, can effectively protect operating personnel's inherently safe, avoid the generation of equipment and security incident.
Description
Technical field
The utility model belongs to high voltage electric equipment field, relates to a kind of high-tension electricity magnetic padlock with voice alarm function.
Background technology
The electromagnetic lock that is applied in high voltage electric equipment field is arranged on the door of high-tension apparatus.When high-tension apparatus does not have electric time, just can open high-tension apparatus door; In the situation that high-tension apparatus is charged, can not open high-tension apparatus door.Staff easily, when high-tension apparatus is charged, carries out maloperation to electromagnetic lock, opens high-tension apparatus door, the as easy as rolling off a log generation that causes equipment and security incident.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of in the situation that high-tension apparatus is charged, the high-tension electricity magnetic padlock of energy audio alert.
High-tension electricity magnetic padlock with voice alarm function of the present utility model, comprises the master switch of power supply, electromagnet and control magnet switching, and described master switch is arranged on main circuit; It also comprises and the phonetic alarm device of electromagnet parallel connection and constant open contact that connect with phonetic alarm device, can be closed in the time sensing high-tension apparatus voltage signal.
It also comprises and the relay indicating light of electromagnet parallel connection and the constant close contact of connecting with relay indicating light, can disconnect in the time sensing high-tension apparatus voltage signal.
The utility model has the advantage of: charged at high-tension apparatus, can not open high-tension apparatus door in the situation that, when electromagnetic lock is operated, can sound and report to the police, can effectively protect operating personnel's inherently safe, avoid the generation of equipment and security incident.
Brief description of the drawings
Fig. 1 is the circuit theory diagrams of the utility model embodiment.
Detailed description of the invention
As shown in the figure, a kind of high-tension electricity magnetic padlock with voice alarm function, comprises power supply, controls the electromagnet 2 of electromagnetic lock blocking mechanism and the master switch 1 of control electromagnet 2 break-makes, and described master switch 1 is arranged on main circuit; It also comprise the phonetic alarm device in parallel with electromagnet 23 and in the time sensing high-tension apparatus voltage signal the constant open contact 4 of closure, described constant open contact 4 is connected with phonetic alarm device 3, controls the break-make of phonetic alarm device 3.
The constant close contact 6 that it also comprises the relay indicating light in parallel with electromagnet 25 and disconnects in the time sensing high-tension apparatus voltage signal, described constant close contact 6 is connected with relay indicating light 5, controls the break-make of relay indicating light 5.
After closed master switch 1, if high-tension apparatus is charged: constant open contact 4 can be closed, phonetic alarm device 3 warning of can sounding.Constant close contact 6 disconnects, and relay indicating light 5 does not work.
After closed master switch 1, if high-tension apparatus is not charged: constant open contact 4 is not closed, phonetic alarm device 3 warning of not sounding.Relay indicating light 5 is bright, and demonstration can continue operation.
