[0017] Compared with the prior art, the present invention has the following beneficial effects: 1.

The conductive plate on the detection platform can detect whether the bottom of the incoming cabinet is leaking after power is turned on, and the penetration effect of the current on the bottom of the incoming cabinet. The size of the magnetic field depends on the size of the current. The larger the current in the incoming cabinet, the stronger the magnetic field generated.

[0018] 2. The mobile detection mechanism is lightweight, easy to carry and install. It is driven by remote control to run on the cable. The cables are tested in sequence along the extension direction of the cables. The cleaning pad at the front uses felt to wipe the surface of the cables to reduce the impact of dust on the test data. Electromagnetic sensors are installed in the test board and the clamping ring. When the current passes through the cable, it will move rapidly along the wire. This movement causes a magnetic field around the cable. The current in the cable is determined by detecting the strength of the magnetic field around the cable. It helps testers determine the optimal configuration of a certain unit length of cable and the number of electrical components in the incoming cabinet in order to achieve the best use effect.

[0019] 3. An air inlet and fins are provided at the bottom of the mounting shell to reduce the impact of air resistance on the mobile detection mechanism.

[0045] When in use, the incoming line cabinet 30 is placed on the rotating disk 103 of the testing table 10. The direction of the incoming line cabinet 30 can be adjusted by controlling the rotating motor 101, so that the bottom of the incoming line cabinet 30 contacts the conductive plate 104. The clamping head 203 can be abutted against the side wall of the incoming line cabinet 30 by controlling the extension and contraction of the cylinder 202 to clamp the wire cabinet 30. The lower clamping head 203 is fixedly arranged and its length cannot be adjusted. It is used to control the distance between the incoming line cabinet 30 and the upper clamping head 203 when the incoming line cabinet 3 is initially placed. The length of the lower clamping head 203 is about 5-10 cm longer than that of the upper clamping head 203.

[0046] Furthermore, the incoming line cabinet 30 can be placed between multiple groups of test tables 10, and the cables 301 can be used to electrically connect them. After power is turned on, the charging performance of the incoming line cabinet 30 can be tested. Through the conductive plate 104 and the electromagnetic sensor inside it, it can be detected whether the bottom of the incoming line cabinet 30 is leaking after power is turned on, and the penetration effect of the current on the bottom of the incoming line cabinet 30. The detection principle is: using the magnetic field induction principle of the electromagnetic sensor for detection. Under normal circumstances, the current is caused by the movement of charged particles in the wire. When the current passes through the wire, it will move rapidly along the wire. This movement causes a magnetic field to exist around the incoming line cabinet 30. Electrons carry negative charges, and the movement of electrons can be regarded as a current loop. The magnetic field generated by this loop is actually the magnetic field generated when the current passes through the wire. The size of the magnetic field depends on the size of the current. The larger the current in the incoming line cabinet 30, the stronger the magnetic field generated.

[0047] Furthermore, a display is provided on the control box, which is electrically connected to the electromagnetic inductor on the conductive plate 104 and displays the detection data to help the test personnel understand the impact on the incoming line cabinet 30 when it is powered on.

[0048] At the same time, a mobile detection mechanism 40 is configured on the cable 301 to detect the impact on the cable when different numbers of electrical components are configured in the incoming cabinet 30. Generally, the more electrical components there are, the more dispersed their positions are, and the longer the wiring length is, the greater the resistance and inductance generated by the cable, which will cause the voltage of the incoming cabinet 30 to drop and the work efficiency to decrease. Therefore, it is necessary to test and debug the optimal configuration of a certain unit length of cable 301 and the number of electrical components in the incoming cabinet 30 in order to achieve the best use effect.

[0049] Furthermore, the detection principle of the mobile detection mechanism 40 is also the magnetic field induction principle, which detects the current change by sensing the magnetic field change around the cable 301. At the same time, the mobile detection mechanism 40 has a large modification space and can also be mounted on the transmission line to detect the transmission line and troubleshoot the fault point.

[0050] Specifically, the cable 301 is inserted into the clamping ring 402, which is composed of two half clamps connected in rotation. After clamping the cable 301, the two half clamps are threaded and fixed with long bolts. The aperture of the clamping ring 402 is larger than that of the cable 301, so that the cable 301 can slide in the clamping ring 402. The rest of the cable 301 extends forward through the top surface of the electrical test board 404.

[0051] Furthermore, the mobile detection mechanism 40 is driven by a remote control motor 403, and a dual drive motor is used, the right remote control motor 403 corresponds to the two drive wheels 406 at the rear side, and the left remote control motor 403 corresponds to the two drive wheels 406 at the front side, and the two remote control motors 403 rotate synchronously. The drive wheel 406 abuts against the side wall of the cable 301, and the mobile detection mechanism 40 runs on the cable 301 through the rotation of the drive wheel 406, and performs detection in sequence along the extension direction of the cable 301.

[0052] The working principle of the detection mechanism 40 in this solution is that the mobile detection mechanism 40 passes through the cable 301 in sequence. First, the cleaning pad 407 at the front end uses felt to wipe the surface of the cable 301 passing through to reduce the impact of dust on the detection data. Then, electromagnetic sensors are set in the test board 404 and the clamping ring 402. The detection principle is also magnetic field induction. When the current passes through the wire, it will move rapidly along the wire. This movement causes a magnetic field to exist around the cable 301. Electrons carry negative charges. The movement of electrons can be regarded as a current loop. The magnetic field generated by this loop is actually the magnetic field generated when the current passes through the wire. The size of the magnetic field depends on the size of the current. The larger the current in the wire, the stronger the magnetic field generated. The current situation is judged by detecting the magnetic field strength around the cable 301.

[0053] Furthermore, an indicator light 411 and a buzzer are provided at the front end, and a trigger threshold is set in the electromagnetic sensor in the mobile detection mechanism 40. When the detected magnetic field strength is lower than or higher than the trigger threshold, the indicator light 411 lights up and the buzzer sounds an alarm, indicating that there is a problem with the cable 301 at that location, or that the power transmission line at that location is faulty as a whole. The detection is very convenient and easy to carry and install.

[0054] Furthermore, an antenna 408 is provided at the front end of the mounting shell 401 to receive signals from a remote controller to control the stop and rotation of the driving motor 403. Wireless transmission and positioning functions can also be added according to existing principles by adding a wireless transmission module and a positioning chip, which has a high prospect for modification and is widely used.

[0055] Furthermore, an air inlet 410 and fins 412 are provided at the bottom of the mounting shell 401, which can reduce the effect of air resistance on the mobile detection mechanism 40. The air inlet 410 squeezes the passing air and transmits it backwards, forming a driving force at the rear, thereby reducing the overall air resistance.

[0056] The above description is only a specific implementation mode of the present invention, and various examples do not constitute a limitation on the essential content of the present invention.
