Abstract

The invention relates to a discharge phenomenon detection circuit based on a night vision technology. A program control unit U7 of the circuit is connected with a serial port debugging interface, a first equipment power supply control circuit, a second equipment power supply control circuit, a temperature measurement interface, a first 485 communication chip U1, a second 485 communication chip U8and a power supply anti-reverse and clamping protection circuit. The circuit solves the problem that an existing circuit for detecting the discharge phenomenon of the insulator cannot clearly detect the discharge arc climbing phenomenon of the insulator at night.

Description

technical field [0001] The invention relates to the technical field of insulator discharge detection, in particular to a discharge phenomenon detection circuit based on night vision technology. Background technique [0002] The insulator is a special insulation control, which can play the dual role of supporting the wire and preventing the grounding of the current in the overhead transmission line. Insulators are used in the connection between the pole tower and the wire, and the connection between the frame of the substation and the line. Insulators are used to increase creepage distances and are usually made of glass or ceramic. Insulators should not fail due to various electromechanical stresses caused by changes in the environment and electrical load conditions, otherwise the insulator will not play a significant role and will impair the service and operating life of the entire line. [0003] The discharge fault of the insulator mainly includes flashover and breakdown....
