Problems solved by technology

These patents have achieved a good solution to the above problems, but the number of arc extinguishing devices in these protection devices is limited. Frequent replacement will greatly increase the maintenance cost, and if the working frequency of the arc extinguishing device is increased, the structural design of the arc extinguishing chamber will inevitably increase the weight of the arc extinguishing device, which is not conducive to long-term use

Abstract

The invention discloses a countable double-cutoff lightning arrester which comprises a lightning arrester body, arc extinguishing air pellets and a counter. A pellet storage bin and a multiport arc extinguishing tube are arranged inside the lightning arrester body, a rail for horizontally discharging the arc extinguishing air pellets is arranged in the pellet storage bin, a reserve rail is arranged at the bottom of the rail, an air pellet trigger is arranged at the tail end of the reserve rail, trigger electrodes connected with an induction coil are arranged on two sides of the air pellet trigger respectively and used for acquiring lightning pulse electric signals, the multiport arc extinguishing tube is provided with a plurality of outlets, air guiding balls are arranged inside the multiport arc extinguishing tube, one end of the multiport arc extinguishing tube is externally connected with an arc striking electrode, and the other end of the multiport arc extinguishing tube points to a counting press point. The countable double-cutoff lightning arrester is simple in structure, large in air pellet storage quantity, reliable in action, stable in operation and fine in arc extinguishing effect, and the air pellets can automatically glide and advance and can be smoothly triggered under the action of gravity.

Description

technical field [0001] The invention relates to a lightning protection and arc extinguishing protection device, in particular to a countable double-cut lightning protection device. Background technique [0002] Lightning protection of transmission lines has always been an important part of the lightning protection work of the power sector, and lightning faults are still one of the important factors affecting the safety of the power grid. The impact flashover caused by lightning strike on the transmission line will cause the line insulator to flash over, and then generate a large power frequency continuous current, damage the insulator string and fittings, and cause a line accident. The traditional "blocking" lightning protection method cannot fundamentally solve the lightning strike problem due to its limitations. Therefore, the power sector generally adopts the installation of parallel protection gaps or line arresters on the transmission line to realize the protection lin...
