Known, with the expansion of urban and rural power grids and increasing for cable outlet, system capacitive earth current sharply increases, single
Flow through that fault current is larger, and electric arc is not easy to extinguish after being mutually grounded, easily produce intermittence arc grounding over-voltage, cause accident to be jumped
Lock rate substantially rises.
In order to solve the above problems, nationwide integrated power grid generally employs resonance neutral grounding, i.e., installs arc blowout wire in neutral point
Circle.When single-phase earthing occurs, because inductance current caused by arc suppression coil compensate for the capacitance current of trouble point, thus make event
The residual flow of barrier point diminishes, and so as to reach nature blow-out, prevents fault spread or even eliminates the purpose of accident.
By taking Henan Province as an example, only 1 year 2016 the whole province increases arc suppression coil 201 newly.At present, electric company of Henan Province ties up
The arc blowout wire number of turns up to 1274 is protected, quantity will be on the increase from now on.Inventor is further to electric company of Luoyang City
Arc suppression coil defect is counted within 2016, it is found that tracing compensation defect not in place occurs more than 10 and risen altogether.This defective effect
Greatly, once occurring, it will increase electric network fault risk.
Because maintainer lacks means of testing to arc suppression coil tracing compensation ability.At present, our common experiment sides
Method is that electric current and voltage are added at new arc suppression coil control system terminal block, carries out simulation test, is only capable of observing arc suppression coil certainly
Dynamic compensation device voltage, whether electric current shows and run indication signal normal, it is impossible to reflect the tracing compensation ability of arc suppression coil,
To its running status can not complete control, also hidden some dangers for for tracing compensation defect not in place.
Found by investigation, in the market does not have satisfactory instrument available for purchase.Meanwhile during producer's field adjustable, only
It is connected on arc suppression coil and is tested using several capacitors, commissioning device is simple and crude, and result of the test is unreliable, and costly
Deng, therefore develop a kind of arc suppression coil debugging and be just particularly important with capacitance current generator, and debug and use in arc suppression coil
Guidance panel is one of very crucial part in capacitance current generator, then how to provide a kind of arc suppression coil debugging electric capacity
Current feedback circuit control module is equally also critically important.
