[0003] However, the internal drainage wires in existing distribution cabinets increase with the grounding devices required inside the cabinet. Generally, the grounding fault detection process of distribution cabinets can only perform range detection, resulting in difficulty in checking each line of each device and equipment and quickly positioning them. It requires subsequent maintenance personnel to check within the range, making the entire grounding fault detection process inefficient and time-consuming. Therefore, it does not meet the existing requirements. For this reason, we propose a distribution cabinet with a grounding fault detection function and its usage method. Summary of the Invention

A heat dissipation port is provided above the external connection box. A base is provided below the power distribution cabinet body.

[0014] Preferably, the usage method of the power distribution cabinet with the function of detecting ground faults includes the following steps:

[0015] Step 1: Connect one end of the copper core wire to the cabinet grounding bolt, insert the other end into the insertion port at the inner detector, use the wire management bottom row to manage the wires, clamp and fix the docking clamp with the installation device, and the connected drainage wire is positioned by the horizontal positioner and the vertical positioner. One end of the drainage wire is inserted into the insertion port at the inner detector.

[0016] Step 2: The wires inserted into the interior from the insertion port converge in the wire bundler. The wire bundler uses multiple detection channels to distinguish the wires, and a Hall current sensor on one side is used to detect the wire current. By detecting whether the wire current is normal, the effect of fault detection and troubleshooting can be achieved. The data during the detection process is fed back to the processor, and the processor then processes and feeds back the data to the display screen for the user to know the detection situation in each detection channel.

[0017] Step 3: The wires pass through the middle of the inner detector and then extend to the external external box. The wire bundling block changes the horizontal placement of the wires to a vertical placement, so that the wires enter the detection box from the wire bundling positioning box. In the detection box, the positioning detection mechanism is moved downward to above the wires by adjusting the lifting rod, so that each wire is separated in different separation holes. The resistance detector and the touch induction block at each separation hole are relied on to detect and sense the resistance value below. By sensing and detecting the resistance value, ground fault detection is carried out on different wires. The data obtained from the detection is fed back to the display through the external processing box for the user to observe and know, and the grounding wire port at the bottom is used for connecting the underground wires.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The present invention uses the inner detector and the positioning detection mechanism in the detection box to detect different positions of the line part in the ground fault in different ways. During the detection process, the corresponding wire bundling and separation components are used to separate the lines, so that the different lines do not interfere with each other, and the accuracy during the detection can be improved. It can accurately position a single set of wires, and at the same time meet the wire management effect in the case of a large number of grounding lines in the cabinet, saving the user the time-consuming of fault detection and troubleshooting and improving the efficiency of fault detection and troubleshooting.

[0020] 2. The wire passes through the middle of the internal detection component and extends to the external external connection box. The wire is changed from a horizontal placement to a vertical placement through a wire bundling block, so that the wire enters the detection box from the wire bundling and positioning box. Inside the detection box, the positioning detection mechanism is moved downward to above the wire by adjusting the lifting rod, so that each wire is separated in different separation holes. The resistance detector and the touch induction block at each separation hole are relied on to detect and sense the resistance value below. The grounding fault detection is carried out on different wires by sensing the resistance value. The detected data is fed back to the display through the external processing box for the user to observe and know. The above structure can improve the detection accuracy and can perform positioning detection on a single wire. BRIEF DESCRIPTION OF THE DRAWINGS
