| description | The invention discloses a partial discharge routing inspection device applicable to multiple detection methods. The device comprises an ultrahigh-frequency sensor with the frequency band ranging from 500 MHz to 1.5 GHz, a high-frequency current sensor with the frequency band ranging from 0.5 MHz to 50 MHz, a ground electric wave sensor, a contact ultrasonic sensor and a non-contact ultrasonic sensor. The ground electric wave sensor and the non-contact ultrasonic sensor are arranged inside a host, the ultrahigh-frequency sensor and the high-frequency current sensor transmit data to the host in a wireless mode through a wireless collection module, the host is mainly composed of a signal collection unit, a data processing module and a human-computer interaction interface, and the host analyzes collected partial discharge data, judges whether partial discharge exists or not, analyzes the partial discharge type and evaluates working conditions of high voltage electric power equipment.
