Background technology
Damage to crops caused by thunder can affect greatly transmission line of electricity operation, heavy then cause device damage, and circuit has a power failure for a long time on a large scale and causes heavy economic losses, gently then causes line tripping.Transmission line of electricity is run to the impact caused to tackle damage to crops caused by thunder, just need immediately to check that transmission facility suffers thunderbolt position whether to cause device damage, the transmission line of electricity reaching hundreds of kilometer is often searched the thing wasted time and energy in thunderbolt position very much, in lightning strike accident, because thunderbolt causes OPGW optical situations such as stock of breaking to happen occasionally, usually this situation injures the operation of electrical network, therefore be necessary to be struck by lightning real-time position monitor to OPGW, for on-the-spot OPGW running status inspection location provides foundation.
At present, thunderbolt Position monitoring devices mainly contains two kinds of modes, and one is mounted in for wire thunderbolt location on transmission line wire, and on the tower bar of the another kind of circuit serious at damage to crops caused by thunder, whether installation thunderbolt monitoring device is struck by lightning for monitoring this tower bar.The first can only be used for wire thunderbolt location, OPGW thunderbolt location can not be used for, the second needs on each tower bar of circuit, install thunderbolt monitoring device, this mode equipment cost is higher, equipment in the wild in rugged surroundings the poor signal of communication of operation stability bad, safeguard inconvenience, often less use.
Summary of the invention
There is above-mentioned problem and deficiency to overcome prior art in object of the present invention, provide a kind of reliably, monitor transmission line of electricity OPGW that is wide, high position precision and to be struck by lightning Position monitoring devices, for monitoring thunderbolt position in location when OPGW is struck by lightning.
Technical scheme of the present invention is:
A kind of for transmission line of electricity OPGW thunderbolt Position monitoring devices, comprise OPGW optical cable, LASER Light Source, light signal conditioner, electric signal conditioner, wave filter, capture card, power panel and industrial computer, it is characterized in that: described OPGW optical cable is communicated with A, B two transformer substation communication machine rooms, LASER Light Source connects light signal conditioner, and light signal conditioner is connected with the optical fiber of FC single-mode fiber jumper with OPGW optical cable A transformer substation end by metallic sheath fiber connector; Optical fiber corresponding to OPGW optical cable B transformer substation end is connected with another optical fiber in same core, and another optical fiber corresponding to OPGW optical cable A transformer station connects wave filter; Described wave filter connects electric signal conditioner, and electric signal conditioner exports electric signal and connects capture card; Described capture card is contained on the bus slot of industrial computer; Described power panel is that all active devices are powered.
In described OPGW optical cable, an optical fiber is as distributed fiberoptic sensor.
The present invention also comprises industry control cabinet, and described LASER Light Source, light signal conditioner, electric signal conditioner, wave filter, power panel and industrial computer are installed in industry control cabinet.
Described industrial computer controls the lightning wave data that capture card gathers transmission line of electricity OPGW.
The present invention can monitor the position that OPGW is struck by lightning by lightning wave waveform when being struck by lightning and location transmission line of electricity OPGW.
Structure of the present invention is simple, and transmission line of electricity OPGW thunderbolt Position monitoring devices is arranged on transformer substation communication machine room, industrial computer Real-time Collection thunderbolt lightning wave data, when there being thunderbolt, and industrial computer meeting real time record lightning waveform and thunderbolt position, and alarm.The present invention thoroughly can solve the narrow and stability problem of communication that traditional monitoring device exists under adverse weather condition, monitoring surface, opens the new direction of electric power monitoring technology.
