Electricity testing equipment for rapidly detecting live-line and power-off states of power transmission cable

The utility model relates to an electricity testing device for quickly detecting live-line and power-off states of a power transmission cable, which comprises a control host and a cable magnetic field data acquisition terminal. The cable magnetic field data acquisition terminal is provided with a first central processing module, a first wireless transceiver module, a power supply management module and a magnetic field sensor and is used for processing and converting an acquired cable magnetic field into data, and the control host is provided with a second wireless receiving module, a second central processing module and a touch screen. The second wireless receiving module is used for receiving data transmitted by the cable magnetic field data acquisition terminal; and after the data is processed by the second central processing module, a logic judgment result and detection data are displayed on the touch screen. According to the utility model, rapid detection and electricity verification can be carried out on
