Abstract

The invention discloses an arc extinguishing method of a recoil arc extinguishing lightning protection insulator, and belongs to the technical field of lightning protection. When a tower or a power transmission line lead is struck by lightning and insulator flashover occurs, lightning arc always selects a channel which is shortest in path and is most conductive to the ground to be discharged to the ground. A plurality of recoil pipes which are installed on the periphery of the skirt edge and swing left and right at a certain inclination angle form an arc extinguishing channel, the channel shortens the length of a lightning stroke flashover path through lightning arresting electrodes in the recoil arc extinguishing pipes to play a role in insulation matching, and the lightning stroke flashover path is overlapped with the recoil arc extinguishing channel according to the control rule of insulation matching. According to the invention, the effect of step-by-step arc extinguishing through the plurality of recoil pipes is good, the process of impacting an arc building channel and inhibiting power frequency arc building can be effectively destroyed, and compared with a traditional insulator, the insulator additionally provided with the recoil pipes can be used for backflushing and jetting a flowing arc so that the effects of protecting the insulator and preventing the insulator from bearing huge pressure are achieved.

Description

technical field [0001] The invention relates to the technical field of lightning protection, in particular to an arc extinguishing method for recoil arc extinguishing lightning protection insulators. Background technique [0002] Lightning is extremely harmful to the safe operation of transmission lines, often causing insulator flashover accidents, especially in mountainous areas and areas with inconvenient traffic, which adds a lot of difficulty to inspections and fault finding. The faults of transmission lines account for the majority of accidents in the power grid, and lightning trips account for a large proportion of transmission line faults. Especially in transmission lines in mountainous areas, line faults are basically caused by lightning trips. According to operating records, Half of the power supply failures of overhead transmission lines are caused by lightning, so preventing lightning tripping can greatly reduce the failure of transmission lines, thereby reducing ...
