Abstract
The invention relates to a lightning stroke maintenance-free circuit, which comprises a lightning protection device with a lightning protection function, and an automatic coincidence device, wherein the automatic coincidence device is connected with the lightning protection device in parallel for implementing detection and can automatically coincide in the first time after tripping. A tripped electric transmission line can be switched on, so that severe influence caused by outage is avoided, and line transportation can be automatically restored in a short time.
Description
Technical field
The present invention relates to electronic technology field, refer in particular to the non-maintaining circuit of a kind of thunderbolt.
Background technology
Along with the development of electric power transmission network, communications network etc., the scale of electrical network also increases day by day, is distributed widely in various places, town and country industry-by-industry, develops into even some remote mountain areas or knob.Transmission line is the element of electrical network, according to summary in the past, once transmission line breaks down, will directly affect the safe and reliable operation of circuit, when serious, can cause large area blackout, even damages rear end electric equipment or operation system.Be exactly lightning stroke trip and cause a key factor of transmission line malfunction, particularly along with the development of technology, the accident that the reduction of Past Voltage within Power System causes reduces, the line tripping accident that thunderbolt is caused occupies day by day main status, thereby safety, the stable operation of lightning stroke trip to electrical network forms significant threat.
In order to reduce lightning stroke trip accident; the method of existing improvement has a variety of; as install line thunder protection device additional; within the shortest time, the instantaneous overvoltage of scurrying into power line, signal transmssion line is limited in the voltage range that equipment or system can bear; the a large amount of pulse energy short circuits that produce because of lightning induction on the release circuit the earth of releasing; potential difference between the each interface of reduction equipment, thus the equipment in protective circuit or system are not hit and damage.But do not mate when lightning protection device grade, when maximum shock-resistant electric current is less than the impulse current of thunder and lightning of actual entry-line, gently lightning protection device itself will be damaged, heavy still can cause trip accident, even cause the damage of equipment or system.Also having one is to adopt multistage lightning protection device, continuous reduction by multistage lightning protection device to instantaneous overvoltage, the continuous decay on circuit, makes the voltage producing after afterbody lightning protection be less than the voltage of rear end electricity consumption, ensure safety utilization of electric power, thunder and lightning is progressively weakened to harmless level.This mode is the same, in the time of first order lightning protection, if can not be effectively can tolerance range by lower voltage to load, also can cause trip accident.Widely distributed due to these transmission lines, staff can not be in time circuit is overhauled, and caused trip accident likely can continue to continue, and production operation is caused to significant impact.
Therefore, be necessary to provide the non-maintaining circuit of a kind of new thunderbolt to overcome the problems referred to above.
Summary of the invention
Based on this, be necessary to provide a kind of non-maintaining circuit of thunderbolt that can automatically recover at short notice circuit transport.
The present invention is achieved by the following technical solutions: the non-maintaining circuit of a kind of thunderbolt, comprise the lightning protection device with lightning protection function, and be connected in parallel with examinations can be finding after tripping operation the automatic reclosing device of automatic reclosing in the very first time with described lightning protection device.
The non-maintaining circuit of described thunderbolt also comprises the first control centre that is connected to realize automatic reclosing device described in Long-distance Control with described automatic reclosing device.
The non-maintaining circuit of described thunderbolt also comprises the second control centre that is connected to realize lightning protection device described in Long-distance Control with described lightning protection device.
The non-maintaining circuit of described thunderbolt further comprises power supply and load, and one end of described lightning protection device is connected and other end ground connection with described power supply, and one end of described automatic reclosing device is connected with described power supply and the other end is connected with described load.
Beneficial effect of the present invention is as follows: the non-maintaining circuit that is struck by lightning comprises lightning protection device and is connected in parallel with lightning protection device also can be at the automatic reclosing device of finding automatic reclosing in the rear very first time of tripping operation with examinations, transmission line after tripping operation can be connected, that has avoided that power-off causes has a strong impact on, and realizes and in the short time, automatically recovers circuit transport.
Brief description of the drawings
Fig. 1 is the be struck by lightning schematic diagram of non-maintaining circuit of the present invention.
Embodiment
Please refer to the drawing 1, the present invention discloses the non-maintaining circuit 100 of a kind of thunderbolt, comprise the lightning protection device 110 with lightning protection function, and be connected in parallel with examinations can be finding after tripping operation the automatic reclosing device 120 of automatic reclosing in the very first time with lightning protection device 110, transmission line after tripping operation can be connected, that has avoided that power-off causes has a strong impact on, and realizes and in the short time, automatically recovers circuit transport.
The non-maintaining circuit 100 that is struck by lightning also comprises the first control centre 130 that is connected to realize Long-distance Control automatic reclosing device 120 with automatic reclosing device 120, and is connected the second control centre 140 that realizes remote control lightning protection device 110 with lightning protection device 110.
Concrete, the non-maintaining circuit 100 that is struck by lightning further comprises power supply 150 and load 160.One end of lightning protection device 110 is connected and other end ground connection with power supply 150.One end of automatic reclosing device 120 is connected with power supply 150 and the other end is connected with load 160.
Preferably, the first control centre 130 and the second control centre 140 can be a control centre.
The non-maintaining circuit 100 of the thunderbolt of the present invention automatic reclosing device 120 that is connected in parallel in lightning protection device 110 rear ends, by the examinations of automatic reclosing device 120, automatic reclosing in the very first time after discovery tripping operation, transmission line is connected, that has avoided that power-off causes has a strong impact on, and reduce staff's maintenance test too frequently, reduced line upkeep cost and human cost.Meanwhile, automatic reclosing device 120 and the first control centre 130 realize Long-distance Control, up-to-date running status is fed back to the first 130, the first control centres 130 of control centre in time and also new data more can be sent to automatic reclosing device 120.When automatic reclosing device 120 has fault, the first control centre 130 also can be sent to automatic reclosing device 120 by new data more.When automatic reclosing device 120 has fault, the first control centre 130 can detect reparation online, and the fault of checking on the spot again that can not repair shows, thereby repairs this device.Lightning protection device 110 can reach data the second control centre 140 after losing efficacy because tripping operation is temporary transient, carries out online detection repair by the second control centre 140.After lightning protection device 110 damages really, detect again replacing on the spot.
Above-mentioned listed specific implementation is nonrestrictive, and for a person skilled in the art, not departing from the scope of the invention, the various modifications and variations of carrying out, all belong to protection scope of the present invention.
