Description
Technical field
The utility model relates to a kind of Intelligent electric power carrier wave graded latch device, belongs to electric power system resist technology field.
Background technology
At present, domestic underground power supply system adopts multistage system mostly, between the superior and the subordinate without blocking function, when subordinate overhauls, mostly by phone or the power failure of sending someone, the magnetic starter of subordinate particularly, because environment for use is abominable, fault is more, often someone's youngster's maintenance of going to uncap, the hot line job phenomenon occurs often, and this operation against rules directly jeopardizes life safety.
Outage is not uncapped, and serious potential safety hazard is arranged.Only locking load-side of the locking device power supply of switch door closure at ordinary times, and the side power supply of can't cutting off the electricity supply, exactly the mains side power supply is the place that causes that least the mine electrician notes, so charged uncapping arranged during the down-hole.The faults such as the ground connection that causes because of misoperation, short circuit can be detected by a plurality of higher levels, thereby the overstep tripping phenomenon can occur, and cause large-area power-cuts, have both affected production, bring unsafe factor to mine again.Up to the present, there is not any mechanical electric interlock in the wire connection cavity loam cake, and the prompting printed words of " first outage, then uncap " are only arranged, and can not stop fully to operate against regulations or misoperation.
The down-hole electric equipment is a lot, and monitoring point, locking point are also a lot, if all adopted line traffic control, cable certainly will increase, and the cable utilance is low.If use wireless remote control, more be not suitable with subsurface environment.
The utility model content
The technical problems to be solved in the utility model provides a kind of energy automatic discrimination faulty line and non-fault line, automatically disengagement failure line power and faulty line implemented locking is stopped to cause the generation of large area blackout and because operating the Intelligent electric power carrier wave graded latch device of the hidden danger that directly jeopardizes life safety against regulations because of personnel's misoperation.
In order to solve the problems of the technologies described above, the technical solution of the utility model provides a kind of Intelligent electric power carrier wave graded latch device, it is characterized in that: comprise the power line coupler that is connected with low-voltage power line, the power line signal modulator-demodulator is connected with power line coupler with signal projector by signal receiver, and digital signal interface is connected with the power line signal modulator-demodulator by single-chip microcomputer.
Preferably, described power line coupler comprises that an end of the first capacitor C 1, the first capacitor C 1 connects live wire, and the other end of the first capacitor C 1 connects an end of the first inductance L 1, an end of a winding of other end connection transformer of the first inductance L 1; The other end of a winding of transformer connects an end of the second inductance L 2, and the other end of the second inductance L 2 connects an end of the second capacitor C 2, and the other end of the second capacitor C 2 connects ground wire; The two ends of the 3rd capacitor C 3 are the two ends of connection transformer secondary winding respectively.
The existing higher carrier signal loading efficiency of a kind of Intelligent electric power carrier wave graded latch device that the utility model provides can fully be isolated again the power frequency component of power network.Need not wiring, Intelligent electric power carrier wave graded latch device is placed in the switch explosion-proof chamber, power line coupler is received on the low-voltage power line got final product.Have following beneficial effect:
(1) stopped directly to jeopardize because of the artificial charged this operation against rules of uncapping the hidden danger of life safety;
(2) stopped to cause because of the overstep tripping that the faults such as ground connection that misoperation causes, short circuit cause the generation of large area blackout;
(3) overcome many because of underground equipment, the monitoring point is many, locking point is also many, has line traffic control will cause control cables numerous, and the low shortcoming of cable utilance;
(4) stopped to uncap the potential safety hazard that the side of can't cutting off the electricity supply power supply causes because not cutting off the power supply;
The device that the utility model provides has overcome the deficiencies in the prior art, energy automatic discrimination faulty line and non-fault line, automatically disengagement failure line power and faulty line implemented locking, stop to cause the generation of large area blackout and because operating the hidden danger that directly jeopardizes life safety against regulations because of personnel's misoperation, and need not wiring, reduced cost, the convenient use.
