Abstract
Disclosed is a no-freewheeling arc lightning protection gap protecting device, comprising a grounding-side arc extinguishing device, and a grounding-side fitting and a conducting wire-side fitting installed at two ends of a circuit insulator string via fixing devices. The grounding-side arc extinguishing device comprises a thunder and lightning pulse acquisition device, an insulating sealing shell, a gas generating device and an arc extinguishing chamber. The other end of the grounding-side fitting is equipped with a connecting fine pipe. The grounding-side arc extinguishing device also comprises a tubular earth electrode made of a nonmetal conductive material and an L-shaped earth electrode. One end of the L-shaped earth electrode is inlaid in and connected with the connecting fine pipe on the grounding-side fitting via a Z-shaped connecting fitting, and the other end of the L-shaped earth electrode penetrates the thunder and lightning pulse acquisition device and is connected with the tubular earth electrode. One end of the nonmetal conductive material tubular earth electrode is internally inlaid in the arc extinguishing chamber, and the other end is connected with the insulating sealing shell. The device improves the electric power system stability and prolongs the service life of the electric power equipment such as transformer and breaker, and has low production and maintenance cost.
