[0060] When the high-voltage motor vibrates in the longitudinal direction, the housing 113 drives the longitudinal sliding block 22 to move in the longitudinal sliding rail 21, and the longitudinal sliding block 22 extrudes the first contraction spring 23, the extruded first contraction spring 23 supports the longitudinal sliding block 22, so that the conductive plate 15 can maintain contact with the rib at all times when the high-voltage motor vibrates in the longitudinal direction;

[0061] When the high-voltage motor vibrates in the horizontal direction, the movable connecting piece 3 drives the transverse sliding block 24 to move in the transverse sliding rail 25, and the transverse sliding block 24 extrudes the second contraction spring 26, the extruded second contraction spring 26 supports the transverse sliding block 24, so that the conductive plate 15 can maintain contact with the rib at all times when the high-voltage motor vibrates in the horizontal direction;

[0062] The movable connecting piece 3 cooperates with the longitudinal moving mechanism and the transverse moving mechanism to maintain the contact between the conductive plate 15 and the rib when the high-voltage motor vibrates in the non-single longitudinal and horizontal directions, the support 31 is connected with the longitudinal sliding rail 21, the hinge shaft 32 is arranged in the support 31, the hinge plate 33 is movably arranged outside the hinge shaft 32 and cooperates with the longitudinal sliding rail 21 to move in the longitudinal direction, the hinge plate 33 is connected with the connecting plate 34, the rotating shaft 35 is arranged between the connecting plate 34 and the transverse sliding block 24, and the rotating shaft 35 can provide rotation for the entire movable connecting piece 3 and the longitudinal moving mechanism;

[0064] To prevent the clamping plate 11 and the conductive plate 15 from being affected by the thermal expansion and contraction of the ribs during the operation and non-operation of the high-voltage motor, a first fixing spring 17 is provided between the conductive plate 15 and the clamping plate 11. When the clamping plate 11 clamps the ribs, the first fixing spring 17 is compressed.

[0067] like Figure 5 As shown, a protective plate 16 is provided on the outside of the conductive plate 15.

[0068] like Figure 3 As shown, the monitoring component includes a first wire 5, a digital current sensor 6, a second wire 7, and a monitoring instrument 8. The first wire 5 is connected to the conductive plate 15 and passes through the protective plate 16 and the adjustment groove 10.

[0073] When the leakage phenomenon occurs in the ribs, it means that the insulation of the whole high-voltage motor is problematic, when the high-voltage motor shell 113 is electrified, the current flows to the ground through the conductive plate 15 and the first lead wire 5 connected with the conductive plate 15, the digital current sensor 6 detects the current and outputs a corresponding voltage signal, and the voltage signal is fed back to the monitor 8 through the second lead wire 7, the signal processing module, the data analysis module and the alarm and display module are arranged in the monitor 8, the signal fed back by the digital current sensor 6 is transmitted to the PLC after being amplified and filtered by the circuit of the signal processing module, the PLC analyzes the signal and judges whether the leakage current exceeds the set threshold value, if the threshold value is exceeded, the PLC controls the alarm to issue an alarm and remotely displays the size of the leakage current through the display screen, so as to realize that the operator can monitor the insulation condition of the high-voltage motor in real time, and the working principle of the built-in element of the monitor 8 is the prior art, which will not be described in detail here.
