Description

A capacitive current generator wiring device for arc suppressing coil debugging

【Technical field】

The invention relates to the field of arc-suppression coil test auxiliary equipment, in particular to a capacitive current generator wiring device for arc-suppression coil debugging.

【Background technique】

It is known that with the expansion of urban and rural power grids and the increase of cable outlets, the capacitive current of the system to the ground increases sharply, and the fault current flowing through the single-phase grounding is relatively large, the arc is not easy to extinguish, and it is easy to generate intermittent arc grounding overvoltage, resulting in accidents The trip rate increased significantly.

In order to solve the above problems, the national power grid generally adopts the resonant grounding method, that is, the arc suppression coil is installed at the neutral point. When single-phase grounding occurs, the inductive current generated by the arc suppressing coil compensates the capacitive current at the fault point, thereby reducing the residual current at the fault point, thereby achieving natural arc extinguishing, preventing the accident from expanding or even eliminating the accident.

Taking Henan Province as an example, in 2016 alone, 201 new arc suppression coils were added in the province. At present, Henan Provincial Power Supply Company has maintained as many as 1,274 arc suppression coils, and the number will continue to increase in the future. The inventor further made statistics on the defects of arc suppression coils in Luoyang Power Supply Company in 2016, and found that there were more than 10 defects of insufficient tracking compensation. This kind of defect has a great impact, and once it occurs, it will increase the risk of grid failure.

Due to the lack of testing means for the maintenance personnel to track and compensate the arc suppression coil. At present, our usual test method is to add current and voltage to the terminal block of the arc suppression coil controller, and conduct a simulation test. It can only be observed whether the voltage and current display and the operation indication signal of the arc suppression coil automatic compensation device are normal, and it cannot reflect whether the arc suppression coil automatic compensation device is normal or not. The tracking compensation ability of the arc coil cannot fully control its operating state, and it also lays hidden dangers for the occurrence of defects in tracking compensation.

After investigation, it was found that there were no instruments meeting the requirements available for purchase in the market. At the same time, when the manufacturer debugs on site, only a few capacitors are connected in series on the arc suppressing coil for testing. The debugging equipment is simple, the test results are unreliable, and the cost is high. Therefore, it is particularly important to develop a capacitive current generator for arc suppressing coil debugging. Important, and the wiring device is one of the key components in the capacitive current generator for arc suppression coil debugging, so how to provide a wiring device for the capacitive current generator for arc suppression coil debugging.
