Abstract
In a strong electromagnetic induction environment, the outage line in the double-circuit line on the same tower will produce induced voltage and induced current. The arc generated when the ground wire is manually installed will seriously affect the safe operation of the equipment. Therefore, this paper proposes a grounding device with induced arc suppression function, which improves the ordinary grounding device by utilizing a series resonant circuit. Firstly, the calculation formula of induced electricity of the double-circuit line on the same tower is deduced theoretically. The working principle of the series resonant grounding device with arc suppression function is analyzed, and the action sequence of the device is introduced. Then, according to the topology, the function of each component and the parameter design method are analyzed. Finally, a simulation model of 220 kV double-circuit line on the same tower is built in ATP-EMTP, which verifies the effectiveness of the proposed series resonant grounding device in induced arc suppression.
