Summary:The utility model relates to a resonance-proof arc-suppression coil, which is composed of an inductor Lp and resonance-proof impedance Zf which are connected in series, and the Zf is composed of a nonlinear inductor Lf, a resistor Rf, and a capacitor Cf which are connected in parallel. The utility model can be used individually and can be also connected with a 6KV, a 10KV, and a 35KV electric networks with arc extinguishing coils in parallel, and normal value of a compensating current is 5 amperes or 6 amperes. The utility model can be used with a large and a medium size extinction coils side by side, and the grounding electric networks of the extinction coils can operate in any one compensating area of an over compensating area, a full compensating area, and an under compensating area. The resonance-proof arc-suppression coil has the advantages of flexible and simple adjustment, and in a full compensating range, the resonance-proof arc-suppression coil avoids occurrence of an over-voltage phenomenon of neutral point displacement caused by a disconnection fault of trolley wires.
