description The invention discloses an arc and resonance elimination comprehensive device for a power grid, which solves the problems that the conventional arc elimination cabinet cannot determine a circuit in which arc light is generated and an arc suppression coil cannot limit intermittent arc overvoltage and cannot eliminate high-frequency intermittent arc grounding. The device comprises a high energy voltage limiter, a vacuum contactor, a current limiting fuse, a controller and a voltage transformer; and an operation module of the controller performs operation processing on information sent by a main measurement module, a main control module and a line selection module, and the controller sends an instruction to control the vacuum contactor to correctly act so as to eliminate the arc and the resonance and select a line. The arc and resonance elimination comprehensive device can completely eliminate arc grounding and the resonance of a power grid system, and reliably realizes segment protection for the power grid syst
