The rear side of the outer wall of the functional tube 1 is connected to an electric control box 4 by bolts, and a nozzle pipe 5 is connected and fixed to one side of the rotating servo 302. A vacuum spray bottle 6 is provided inside the functional tube 1, and a coupling agent outlet 7 is opened on the right side of the outer wall of the functional tube 1. A coupling agent tube 8 is fixed inside the coupling agent outlet 7, and one end of the coupling agent tube 8 is fixedly connected to the rotating servo 302. An extrusion motor 9 is provided inside the functional tube 1.

[0023] During use, the staff starts the rotary servo 302 through the remote control, so that the mouth of the nozzle tube 5 is aligned with the probe position of the probe holder 303, and then the extrusion motor 9 is activated to squeeze the vacuum spray bottle 6, and the coupling agent is squeezed out along with the mouth of the nozzle tube 5 and flows on the probe (the probe is not shown in the figure); then the extrusion motor 9 retracts, the vacuum spray bottle 6 is reset, the rotary servo 302 is reset, and the buzzer sounds "squeak, squeak" twice; this is called a "spraying cycle", at this time, the staff can press the test claw 3 to the local discharge position to be tested, after the measurement is completed, find the next position to be tested, adjust the angle of the test claw 3 and the length of the telescopic rod 2, start the next "spraying cycle", and then measure the local discharge again. If the interval between two "spraying cycles" exceeds 15 minutes, in accordance with the principle of saving electricity, the power supply will be automatically disconnected; at this time, the staff needs to turn on the power again.

[0024] The functional tube 1, telescopic rod 2, test claw 3, electric control box 4 and extrusion motor 9 are used to facilitate testing at higher positions, and a single person can complete the partial discharge test at a high position, which not only improves work efficiency but also reduces the risk of high-altitude operations, and can realize the situation where one person can test partial discharge at a high position.
