Technical field: a kind of power-off, open circuit treatment facility, be applicable to various high-low pressure, AC and DC transmission line, and the various field such as commercial unit, wiring board.
Background technology: at supply station power output end, "on" position, cannot know circuit whether to break, under normal circumstances, remote power feeding circuit, no matter high pressure, low pressure, exchange, direct current, to know circuit whether open circuit or power-off at power end (power output end), when power supply administration closes a switch, whether client has electricity, or just in electricity consumption, light sees that reometer cannot judge, one, because storm, weather scrape power-off line, or after other reason electric wire broken, fall on the ground, electric leakage also can generation current, and reometer also can turn; Two, power lead has broken, but export one end and there is no ground connection, leakproof, electricity consumption situation is not had to be the same with client, reometer can not turn, and above-mentioned two situations power supply station staff cannot judge that whether supply line is unimpeded dynamically, initiatively, simply, directly, in real time, effectively, even if use instrument also may not measure, even if instrument can be measured also pretty troublesome, normally passive wait customer phone feedback information.
Daily come electroluminescence instruction, power-off lamp goes out, meet convention, but the present invention, at supply station, detect remote power feeding, reversely realizing power-off, open circuit luminescence instruction or sounding alarm or fault handling, for detecting whether open circuit or the power-off of long-distance transmission circuit, automatically detecting and disengagement failure loop, start stand-by circuit to restore electricity, reach real time high-speed and automatically solve fault object.And the operator on duty of power supply station, need not go out, also call without the need to user or field man, just can grasp transmission line of electricity "on" position in real time: broken string, which electric pole or steel tower broken string situation, timely arrangement personnel process open circuit problem, circuit outside patrolling without the need to personnel.
The present invention is applicable between remote power feeding, Long-distance Control, large mini-plant, equipment therein line supervision.Be convenient for reference.A kind of power-off, open circuit treatment facility technology, foolproof luminescence or sounding alarm prompting, for mutually powering between remote power feeding, equipment, in order to confirm that whether circuit is unimpeded, or broken string state, be also convenient for maintaining, looking up the fault simultaneously, reduce maintenance difficulty, reduce maintenance cost.
Summary of the invention: a kind of power-off, open circuit treatment facility, is made up of transmission line, signal controller, demultiplexer, power supply signal compositor, signal generator; Described transmission line connection signal separation vessel and power supply signal compositor, described transmission line conveying direct current or AC power and signal, described signal power source compositor is coming from the signal syntheses of signal generator on power supply, described signal through transmission line to demultiplexer, Signal separator out, the signal after described separation flows to signal controller to described demultiplexer; When circuit breaking, signal controller can not receive the signal of signal generator, and signal controller controls: luminous indicating lamp warning, control audible alarm, control disengagement failure loop and start back-up circuit, in one or both or three kinds.
Described demultiplexer, power supply signal compositor are electrostatic coupling circuit, or transformer coupled loop, or optocoupler coupling circuit, or transducer signal loop inductance.
Described power end is powered to equipment end, signal by equipment end by transmission line to power end.Described signal generator working power comes from transmission line.
Described power supply signal compositor is one or more power supply signal compositor, and described demultiplexer is one or more demultiplexer.
Described power supply signal compositor is one or more power supply signal compositor, and each compositor is arranged on assigned address on each branch road of transmission line or transmission line respectively; Described demultiplexer is one or more demultiplexer, is arranged on supply station power output end, or assigned address on transmission line, each branch road or transmission line.
