The error compensation unit uses a compensation algorithm to correct the detection result. When the alarm module detects a leakage phenomenon, it promptly sends an alarm signal through the alarm circuit. The alarm circuit includes an audible and visual alarm.

[0025] Further, firstly, the detection box 1 is arranged at a suitable position by bolts. In the subsequent use process, the appearance of the building electrical equipment and the line is first detected by the monitoring equipment, and the detection results are uploaded to the data acquisition device, which includes a data acquisition device 1 2 and a data acquisition device 2 28. Then, the leakage protector, infrared thermal imager ultrasonic technology and millimeter wave radar technology are used to determine whether there is leakage in the equipment or line, that is, leakage detection is performed by one or more of the appearance detection method, the leakage protector detection method and the millimeter wave radar detection method, the infrared thermal imager detection method and the ultrasonic detection method. During the detection process, the use environment of the equipment is monitored, and then the collected data information and environmental information are uploaded to the acquisition device, so that the signal amplifier 6 can amplify the collected data signal and transmit it to the comparator 7 to compare the amplified signal with the preset leakage action current value. If the amplified residual current signal is greater than or equal to the preset value, it is determined that leakage occurs; The appearance inspection method monitors the appearance of equipment or lines through the deployment of monitoring equipment to check whether there is insulation damage, aging or poor contact.

[0031] Furthermore, during the use of the detection box 1, the electrical components inside the detection box 1 are self-detected. When a fault or leakage current is found in the electrical components inside the detection box 1, the power is automatically cut off and the device is switched to the backup detection device. At the same time, the micro-mechanical gripper 17 is started, and the sleeve 10 is clamped by the micro-mechanical gripper 17. At this time, the limit block 18 on the micro-mechanical gripper 17 can be engaged with the limit hole 15 on the sleeve 10, and then the micro-mechanical gripper 17 is driven to move by the cylinder in the storage box 16, so that the sleeve 10 is unplugged from the connector 3. As the sleeve 10 moves, the connecting line 4 can be pushed out of the input port of the data collector 2 under the action of the baffle 13, thereby disconnecting the connecting line 4 from the data collector 2.

[0034] Working principle: First, the detection box 1 is arranged at a suitable position by bolts. In the subsequent use process, one or more more accurate leakage detection methods such as infrared thermal imager detection method, ultrasonic detection method and millimeter wave radar detection method are used on the basis of the appearance detection method superimposed on the leakage protector detection method, so as to accurately identify the leakage signal in the equipment and line, and find out the cause of the leakage current.

When it is found that there is a fault or leakage current in the electrical components inside the detection box 1, the power is automatically cut off and jumps to the backup detection equipment. At the same time, the micro-mechanical clamp 17 is started, and the sleeve 10 is clamped by the micro-mechanical clamp 17. At this time, the limit block 18 on the micro-mechanical clamp 17 can be engaged with the limit hole 15 on the sleeve 10, and then the micro-mechanical clamp 17 is driven by the cylinder in the storage box 16 to move, so that the sleeve 10 is unplugged from the connector 3. As the sleeve 10 moves, the connecting line 4 can be pushed out of the input port of the data collector 2 under the action of the baffle 13, thereby disconnecting the connection between the connecting line 4 and the data collector 2, which can improve the safety of the detection box 1 when in use to a certain extent.
