The partial discharge and condensation in distribution switchgear seriously affect the insulation state, which can cause insulation failure and lead to the shutdown of electrical equipment. This paper designs and develops a set of insulation online monitoring and anti-condensation control system for distribution switchgear. By comprehensive use of transient earth voltage (TEV) technology and ultrasonic technology for partial discharge detection, temperature and humidity detection, control technology and wireless communication technology, the system realizes the online monitoring of insulation, temperature and humidity in switchgear. In addition, the system can automatically control the heater, fan or other environmental adjustment equipment and reduce the occurrence of condensation in switchgear.
