[0023] In summary, the switch device fault detection device with built-in multi-channel sensor has the following advantages: Firstly, the universal wheel 2 improves the convenience of the device when moving, and facilitates the movement of the support 6 to the outside of the corresponding switch cabinet. Meanwhile, the limiting plate 4 can quickly correct the position between the base 1 and the cabinet body, which is beneficial to improve the efficiency of detection and avoid the deviation between the detection assembly 8 and the switch cabinet during detection, thereby affecting the detection accuracy. Then, by stepping on the pedal 502, the two synchronous plates 506 can be driven to move synchronously through the rack 503, the transmission gear 504 and the screw rod 505, and the driving plate 507 will push the slide column 508 through the inclined slot inside the driving plate 507, thereby driving the lifting plate 509 to move downward, so that the anti-skid plate 510 is pressed tightly to the ground. Since the bottom of the anti-skid plate 510 is made of rubber material, and the base 1 is relatively heavy, the stability of the base 1 is improved, thereby providing effective protection for subsequent detection work. Secondly, the controller starts the servo motor 701 to drive the rotating plate 702 to rotate, and the driving seat 703 moves along the rectangular trajectory under the limiting of the guide wheel 704 and the guide strip 705, so as to change the position of the detection assembly 8 outside the switch cabinet. In this process, the slide sleeve 710 and the slide rail 711 can improve the stability of the rotating plate 702 under load, and the speed reducer 706 can also drive the lead screw 707 to rotate, so that the lifting seat 708 slides along the outside of the light rod 709, thereby adjusting the height of the detection assembly 8, so that the detection assembly 8 covers the outside of the switch cabinet comprehensively. Then, when the driving electric push rod 801 drives the moving seat 802 to move, the guide rod 803 can improve the stability of the moving seat 802 during movement. At the same time, the distance between the moving seat 802 and the lifting seat 708 increases, the tooth block 902 on the support plate 901 is separated from the adjusting gear 905, the torsional spring shaft 903 is rotated to the open state under the elastic force of the torsional spring and the limiting of the upper cover 808, so that the ultrasonic sensor 809 and the infrared temperature sensor 810 inside the upper cover 808 can detect the switch cabinet. Subsequently, when the electric push rod 801 continues to elongate, the bristles 1007 will be attached to the outer wall of the switch cabinet, the buffer pad 1004 will buffer the activity cover 1003 and the switch cabinet, and the compression spring 1002 will be squeezed and contracted. Then, the activity cover 1003 will slide in the lower cover 804, so that the distance between the cover plate 1006 and the lower cover 804 is reduced, the guide column 1009 will slide along the guide plate 1008, thereby pushing the guide plate 1008, so that the cover plate 1006 moves downward under the limiting of the limiting strip 1005. In this way, the cover plate 1006 is automatically opened, and the bristles 1007 can also clean the detection position of the cabinet wall, thereby avoiding the interference of dust and impurities attached to the detection position of the cabinet wall on the contacts of the transient ground test instrument 807, and the pressure sensor 806 is used to monitor the pressure received by the transient ground test instrument 807, so as to adjust the feeding of the electric push rod 801, and avoid damaging the transient ground test instrument 807 due to excessive pressure: Subsequently, in the detection process, when partial discharge occurs inside the switch cabinet, the particles around the discharge point will appear oscillatory mechanical movement, generating ultrasonic partial discharge signals and spreading around, which can be detected by the ultrasonic sensor 809, while the infrared temperature sensor 810 can detect the local temperature of the cabinet body, and when partial discharge occurs inside the switch cabinet, electromagnetic waves will be generated, which will be transmitted from the cabinet through the openings, joints, door panels and other gaps of the metal cabinet body, along the outer surface of the metal shell to the ground, and at the same time, the transient ground voltage will be excited on the outer surface of the metal cabinet body, so the transient ground tester 807 can be used to detect the transient ground voltage, thereby improving the detection accuracy through multiple channels of sensors; Then, after detection, when the electric push rod 801 retracts, the compression spring 1002 can push the movable cover 1003 to reset it, and the cover plate 1006 can automatically move back to restore the closed state of the side of the movable cover 1003, while the upper cover 808 moves back, the adjusting gear 905 will contact the tooth block 902, driving the torsional spring shaft 903 to drive the protective cover 904 to shield the side of the upper cover 808, thereby providing protection for all sensors after detection. This automatic opening and closing protection design not only effectively avoids the exposure of sensors in non-working state to the field, physically isolates external factors that may cause measurement errors or equipment damage, but also automatically cleans the detection point before each detection, fundamentally ensuring the accuracy and consistency of data acquisition. This double protection mechanism greatly reduces the frequency and difficulty of manual maintenance, and plays a crucial role in improving the reliability, stability and overall service life of the equipment in long-term and repeated use. Finally, after detection, when the base 1 needs to be moved, only need to step on another pedal 502 to make the screw rod 505 reverse, and then through the transmission mechanism to make the anti-skid plate 510 separate from the ground, thereby improving the efficiency and convenience of operation, greatly reducing the labor intensity of the operator, saving the time of transferring and fixing between different stations.
