[0043] The working principle of the utility model is as follows:

[0044] When the cable needs to be tapped, the cable is inserted into the tapping slot of the protective shell 1, and the cable is ensured to be located between the two clamping rings 4. The joint of the cable pushes the cleaning plate 10 to drive the connecting plate 12 to move towards the rear wall of the tapping slot, and extrudes the second spring 14. In the process, the cleaning plate 10 moves along the surface of the connecting column 11, thereby removing the dust on the surface of the connecting column 11, keeping the interface area clean. At the same time, the connecting plate 12 drives the clamping column 13 to move synchronously, so that the clamping column 13 is separated from the surface of the contact plate 13. The clamping column 13 no longer limits the contact plate 13. The elastic restoring force of the first spring 5 pushes the two contact plates 3 to move towards each other, and drives the clamping ring 4 to clamp the cable, preventing the cable from loosening. When the cable needs to be removed, the knob 6 is screwed, the knob 6 drives the arc plate 7 to rotate, until the pulley 8 contacts the contact plate 3. The pulley 8 rolls along the surface of the contact plate 3 and pushes the contact plate 3 to the two sides. The first spring 5 is compressed, the contact plate 3 drives the two clamping rings 4 to move away from each other, thereby releasing the clamping of the cable, facilitating the removal of the cable. In the state of not tapping the cable, the cleaning plate 10 is no longer extruded by the cable. Under the action of the elastic restoring force of the second spring 14, the cleaning plate 10 returns to the initial position to cover the opening of the docking ring 9. The relative closed space is formed by the docking ring 9, the cleaning plate 10 and the rear wall of the tapping slot, which can effectively prevent dust from entering the docking area. At the same time, the clamping column 13 abuts against the surface of the contact plate 13 to fix the contact plate 13, facilitating the subsequent tapping operation.

[0045] When the cable tapping work is completed, the power system is started, the PLC module first checks the working state of the lightning protection module, overload protection module, short circuit protection module and voltage regulation module, confirms whether each module is in normal operation state, in the system operation process, the lightning protection module is at the forefront of the entire protection chain, preferentially detects any transient high voltage or lightning from the power line, when lightning or voltage transient rise occurs, the lightning protection module immediately works, guides the excessive voltage to the ground wire to prevent it from entering the device interior, at the same time, the lightning protection module sends the working state information to the PLC module through the signal line, the PLC timely records and responds to the information uploaded by the lightning protection module; when the lightning protection module works normally, other modules continue to be in standby state, among them: the overload protection module monitors the load current in the circuit in real time, when the load current exceeds the safety value set by the system, the overload protection module immediately takes action, informs the PLC module to start the overload protection process through the signal line, after the PLC module receives the signal of the overload protection module, it quickly issues an instruction to cut off the power supply, protects the electrical equipment from overload, at this time, the working priority of the overload protection module is only next to the lightning protection module, and the protection strategy is automatically adjusted according to the load condition; the short circuit protection module is used to detect the short circuit in the system, once the short circuit occurs, the short circuit protection module will respond quickly, send a signal to the PLC module to require emergency power cut-off, after receiving the short circuit signal, the PLC module will preferentially execute the short circuit protection operation, cut off the power supply quickly to prevent the accident from further expanding or damaging the equipment; the voltage regulation module is responsible for continuously adjusting the power output to ensure that the equipment works in the appropriate voltage range, according to the voltage demand parameters preset by the PLC module, the output voltage is monitored in real time, when the unstable voltage or deviation from the standard is detected, the voltage regulation module automatically adjusts the output voltage, so that the electrical equipment can operate normally, the PLC module receives the state feedback of the voltage regulation module through the signal line, and adjusts the voltage regulation strategy according to the current power situation.
