technical field

The utility model relates to the technical field of transmission line detection systems, in particular to an insulator flashover rapid detection system.

Background technique

Flashover refers to the discharge along the surface of the solid insulator when the gas or liquid dielectric around the solid insulator is broken down. The voltage at which it discharges is called the flashover voltage. After a flashover occurs, the voltage between the electrodes drops rapidly to zero or close to zero. Sparks or arcs in the flashover channel cause local overheating of the insulating surface and cause carbonization, which damages the surface insulation. With the acceleration of my country's industrialization process, power grid planning and construction have achieved rapid development. However, due to the impact of high industrialization in some areas, a large amount of smoke and waste gas are produced, and a large number of transmission line insulators are covered with insoluble water. The phenomenon of flashover occurs frequently, but most of the existing flashover detection systems can only detect the occurrence of flashover, and cannot record the number of flashovers well, and cannot send information to users well, and cannot detect flashovers at the same time. Aiming at the above problems, a fast detection system for insulator flashover is proposed.
