Description
Technical field
The utility model is related to distribution network line singlephase earth fault positioning fields, are connect more particularly, to one kind is single-phase
Earth fault positioning auxiliary device.
Background technology
Singlephase earth fault is the most common failure of distribution system, mostly occurs in moist, rainy weather, due to screen of trees, matches
In electric line caused by the factors such as the single-phase breakdown of insulator, single-phase wire break and toy harm.Single-phase earthing not only shadow
Rung the normal power supply of user, and there may be overvoltage, burn out equipment, if or even occur singlephase earth fault when power grid it is long
Phase runs, and because two phase-to-ground voltages of non-faulting increase, the weak link of insulation may be caused breakdown, developed into alternate short
Road makes fault spread.Distribution line distribution at present is wide, branch is more, and line single phase grounding failure is that service personnel is most difficult to search most
The failure of hardly possible positioning, especially under the inclement weather conditions such as strong wind, heavy rain, singlephase earth fault frequently occurs, and seriously affects
Power distribution network safe and reliable operation.It is learnt according to data consultation, at present for the method for distribution network line singlephase earth fault positioning
Including three kinds of S injection methods, traveling wave positioning mode and fault detector explicit representation etc., but correlation technique still can not thoroughly meet distribution
The solution of line single phase grounding failure orientation problem.
Invention content
The purpose of this utility model is to solve said one or multiple defects, designs a kind of singlephase earth fault positioning auxiliary
Device.
To realize the above goal of the invention, the technical solution adopted is that：
A kind of singlephase earth fault positioning auxiliary device, including it is babinet, terminals, solar panels, voltage transformer, single-phase
Capacitance, vacuum switch, internal controller and back panel wiring end；Wherein terminals and solar panels are arranged in babinet upper surface,
He is each provided at box house by component；The input terminal of wherein voltage transformer is connect with terminals, output end and internal controller
Input terminal connection；The output end of internal controller is connect by back panel wiring end with vacuum switch and single-phase capacitance；Solar energy
Plate is for being powered internal controller.
Preferably, the babinet is cube structure babinet.
Preferably, the babinet is the babinet of isolation material.
Preferably, the single-phase capacitance, vacuum switch, internal controller and back panel wiring end are each provided at the interior bottom of babinet
Portion.
Preferably, the single-phase capacitance quantity is two, is each provided at bottom in babinet.
Preferably, the vacuum switch quantity is two, is each provided at bottom in babinet.
Preferably, the voltage transformer is located at babinet inner top.
Compared with prior art, the beneficial effects of the invention are as follows：
1) by the device between non-faulting phase and the earth the single-phase electricity container of one certain capacity of switching in short-term, artificially
It is alternate " short circuit " that singlephase earth fault is become the instantaneity repeatedly through capacitor and the earth, that is, repeatedly utilizes capacitor switching
Shove will dozens or even hundreds of times of Current amplifier over the ground, when power distribution network high resistance grounding failure to improve multipoint line
The accuracy of positioning；
2) single-phase earth fault positioning device for electrical power distribution network minimizes, and is easily installed.
