[0036] Working principle: When using the coupler, connect the coupler body 1 to the circuit. The main functions of the high-frequency partial discharge signal coupler include signal capture, power monitoring and regulation, system protection, and impedance matching. In addition, the high-frequency partial discharge signal coupler also has the advantages of high sensitivity, wide frequency band, and strong anti-interference ability, and can accurately capture the high-frequency current pulses generated by partial discharge. When using the fixing device 4, pull the fixing strip 417 in the direction close to the coupler body 1 through the third spring 420, so that the fixing strip 417 is arranged on the side of the rotating frame 402 away from the coupler body 1, and the rubber block 418 is squeezed on one side of the rotating frame 402, which can make the rotating frame 402 away from the first connection port 2, thus facilitating the insertion of the connector 412 into the first connection port 2. Then manually insert the connector 412 into the first connection port 2, and drive the rotating frame 402 to rotate on one side of the rectangular strip 401 through the torque force generated by the first spring 407. Then one end of the rotating frame 402 is squeezed on the surface of the connecting sleeve 408. Then manually control the cylinder 403 to rotate on the surface of the rotating frame 402, so that the arc plate 404 is sleeved on the surface of the rubber cylinder 409, and the protrusion 415 is squeezed on the surface of the rubber cylinder 409, which can avoid the arc plate 404 sliding on the surface of the connecting sleeve 408 to a certain extent. Squeeze the sliding cylinder 411 in the direction away from the connector 412 through the second spring 414, and then sleeve the sliding cylinder 411 on the surface of the arc plate 404, which can well limit the arc plate 404 on the surface of the connecting sleeve 408, and thus limit the connector 412 in the first connection port 2 to a certain extent. When using the connecting device 5, squeeze the connecting frame 501 in the direction away from the coupler body 1 through the fourth spring 503, which is convenient to move the parts arranged inside the connecting frame 501 away from the inside of the coupler body 1. After the connecting frame 501 is extruded from the inside of the coupler body 1, the fifth spring 511 squeezes the support block 512 away from the receiving groove 509, which can support the connecting frame 501 through the support block 512, thus facilitating the repair of the parts inside the coupler body 1. After the repair is completed, slide the connecting frame 501 into the inside of the coupler body 1. Pull the L-shaped plate 508 in the direction close to the fixing plate 504 through the sixth spring 507, and then sleeve the L-shaped plate 508 on the top of the coupler body 1. Squeeze the positioning strip 514 in the direction away from the positioning frame 513 through the seventh spring 518, and then squeeze the L-shaped plate 508 into the groove 515, and squeeze the rubber strip 516 to the side of the L-shaped plate 508 away from the coupler body 1, which can limit the L-shaped plate 508 in the groove 515, and then squeeze the rubber rod 519 into the inside of one side of the L-shaped plate 508, which is convenient to limit the fixing plate 504 on one side of the coupler body 1, and squeeze the rubber plate 505 into the inside of the coupler body 1, which can store the parts.

[0037] It should be noted that all the damping rods in this case are telescopic dampers, which can absorb energy during the telescopic process.
