the method comprises the following steps: placing a loop wire frame on the outer side of a main loop cable to enable the main loop cable to be attached to a sensor fixing band, enabling a loop clamping jaw to slide on the inner side of the loop wire frame through an insulating handle until the loop clamping jaw drives a convex ball head to slide into the inner side of a rubber ball socket, and avoiding the loop clamping jaw from sliding randomly through static friction force of the rubber ball socket on the convex ball head;
step two: the main loop cable enters the inner side of a loop wire frame and loop clamping jaw assembly after the loop clamping jaw moves, the loop clamping jaw drives the top end of the sensor fixing band to move, so that the sensor fixing band does circular telemechanical motion, and the main loop cable is located on the inner side of a circular motion track at the moment, so that the sensor fixing band surrounds the outer side of the main loop cable after moving, and the adjusting slide block slides in the opposite direction of the signal transmission block all the time under the tension of the tension spring, so that the shape of the sensor fixing band on the outer side of the main loop cable is changed, the sensor fixing band can be tightly attached to the outer surface of the main loop cable and is arranged in a winding shape, and the automatic setting of the temperature sensor is realized;
step three: the voltage transformer isolation module is connected with a main loop cable, the power industry transformer isolation module generates current through coil mutual inductance, and a current measuring circuit, a leakage measuring circuit and a temperature measuring circuit are arranged on the inner side of the measuring module through a voltage reduction output module to supply power;
step four: the current transformer clamping jaw and the leakage transformer coil mutually induct current in the main loop cable, so that the current measuring circuit measures current parameters, the leakage measuring circuit measures leakage parameters, the temperature sensor is attached to the main loop cable, the temperature measuring circuit measures the temperature parameters of the main loop cable, the switching power supply is turned on, the main loop cable supplies power for the MCU main module, the MCU main module is isolated from the voltage transformer module, the current measuring circuit, the leakage measuring circuit and the temperature measuring circuit, the MCU main module processes and analyzes received data through the human-computer interaction module, and parameter measurement of the main loop cable is achieved.
