Embodiment

The charged locking device of the utility model multifunctional high pressure is achieved in that to do below in conjunction with accompanying drawing and specifies.

See that Fig. 1 is the charged locking device structured flowchart of multifunctional high pressure, among the figure the charged locking device of multifunctional high pressure by: central controller SAG, transducer CG11, electric door lock DSN, cigarette sense module GST, alarm BJ, power module XRA form, and have adopted external and built-in alarm BJ and DC (AC)/dc power module; High-voltage signal inserts transducer CG11 through high-voltage switch gear K, through interface A connection central controller SAG, central controller SAG C interface connects electric door lock DSN, central controller SAG B interface connects cigarette sense module GST, central controller SAG D interface connects alarm BJ, central controller SAG F, G interface joining power module XRA.

See that Fig. 2 is central controller SAG and power module XRA winding diagram, figure mesohigh signal inserts manual relay K 1 through interface A, connect light-emitting diode Da, Db, Dc again, succeed electrical equipment K3 through module relay K 2, relay K 3 connects light-emitting diode D2, power module XRA connects central controller SAG through F, G interface, and connects light-emitting diode D1.

See that Fig. 3 is a cigarette sense module GST winding diagram, power supply inserts B interface among the figure, connects light-emitting diode D3, and cigarette sense module GST succeeds electrical equipment K4, and connects alarm BJ through the K4e interface.

See that Fig. 4 is an electric door lock DSN winding diagram, power supply AC interface connects light-emitting diode D4 among the figure, and push-button switch is succeeded electrical equipment K3c, relay K 3d.

See that Fig. 5 is an alarm BJ winding diagram, alarm BJ connects relay K 3d interface among the figure, connects relay K 4e.

The charged locking device of the utility model multifunctional high pressure is simple in structure, when high-voltage switch gear K closes a floodgate, signal imports central controller SAG into by transducer CG11 to be handled, send instruction and close electric door lock DSN and inaccurate charged broaching tool lock, attempt to open the door or during drag switch as the people, alarm BJ gives the alarm and stops, and avoids misoperation fault.When high-voltage switch gear disconnects, there has not been high voltage in the high-voltage board, transducer CG11 does not have high-voltage signal, and central controller SAG sends instruction electric door lock DSN and allows to open, and allows to draw back the bottom disconnecting link, and this moment, the staff can enter work in the high-voltage board safely.In the high-voltage board operate as normal, during equipment generation high temperature fire fault, cigarette sense module GST starts, and sends signal and gives alarm BJ in the cabinet, and alarm BJ gives the alarm and notifies the operator on duty in time to handle.The utility model adopts the ac-dc dual power supply module, makes it more general and stable, and has improved anti-interference.
