Abstract

The invention relates to a manufacturing method of a series gap lightning arrester, which comprises the steps of manufacturing an insulator for accommodating a series gap point discharge assembly, and arranging a plurality of conductor accommodating groove groups at intervals in the main shaft direction of the insulator, wherein the two adjacent conductor accommodating groove groups arranged in the main axis direction of the insulator in a spaced mode are the first conductor accommodating groove group and the second conductor accommodating groove group respectively, the first conductor accommodating groove group comprises A first conductor accommodating grooves, the second conductor accommodating groove group comprises B second conductor accommodating grooves, the sum of A and B is greater than or equal to 3, when the distance between any first conductor accommodating groove and any second conductor accommodating groove is equal to the set length of the gas discharge channel, the gas discharge channel is formed between the first conductor accommodating groove and the second conductor accommodating groove of the insulator, and the insulator is also provided with an arc extinguishing blind hole communicated with the gas discharge channel. The lightning arrester with the lightning protection effect, the high arc extinguishing effect and the low leakage current can be manufactured by adopting the manufacturing method.

Description

technical field [0001] The invention relates to the field of lightning arresters, in particular to a method for manufacturing a series gap lightning arrester. Background technique [0002] A surge arrester is an electrical appliance used to protect electrical equipment from high transient overvoltage hazards and limit the freewheeling time and often limit the freewheeling amplitude. The existing surge arresters for transmission lines include zinc oxide arresters, series gap arresters and other types. [0003] Patent document CN110829183A describes a lightning protection device for power transmission lines, including lightning electrodes for electrically connecting transmission lines, grounding electrodes for electrically connecting ground wires, and lightning rods for maintaining the distance between lightning electrodes and grounding electrodes. Support the insulator and the lightning arrester arranged between the grounding electrode and the lightning-inducing electrode. T...
