In power system and electronic equipment applications, surge (or surge) is a phenomenon in which voltage rises sharply in a short period of time, usually due to lightning strikes, power switching, inductive load disconnection, etc. Surge may cause transient overvoltage to the connected electronic equipment and even cause equipment damage in severe cases. Thus, surge protection devices become a vital component in electronic equipment and power systems to protect the equipment from surge events.

In addition, the maintenance cost of the traditional device is high, and automatic repair cannot be realized, so that the system can quickly recover to normal operation after a surge event. There are the following problems:

Working principle:
first, a surge event occurs: when a surge event occurs in the external circuit, breakage of the fuse 28 is caused. The breaking of the fuse 28 causes the deflation of the balloon 10, achieving a rapid isolation of the circuit; the limit spring 20 and the connecting spring 21 in the starting device are activated, causing the connecting block 22 to contact the contact piece 23, triggering the starting device. Then, the starting device starts: the activation of the activation means is initiated by the contact of the connection block 22 with the contact piece 23. The electromagnet 6 is magnetically influenced by external current, and attracts the connecting rod 13, so that the connecting rod 13 slides inside the arc chute 15. The connecting rod 13 drives the internal structure to rotate: the displacement of the connecting rod 13 causes the rotation of the inner turntable 1 and simultaneously starts the movement of the connecting disc 5, and the connecting rod 13 in the arc-shaped chute 15 is driven to slide by the left-right movement of the connecting disc 5 due to the fact that the connecting disc 5 contains the first spring 12, the second spring 14 and other components. As the connecting rod 13 slides, the third spring 17, the rotating rod 18 and the fixed rod 19 in the control device 16 start to cooperate, thereby activating the alarm 32. This process ensures that the device can alert in time to alert the user to anomalies in the circuit state when a surge event occurs. The rotation of the inner dial 1 is driven by the connecting rod 13 so that the replacement 4 is gradually transferred to the position of the original connection terminal 2. The process realizes automatic replacement of damaged parts, and ensures continuous and stable operation of the whole circuit. Breaking of the fuse 28 also activates the connection of the opening device 24, so that the booster pump 25 can work, and the cooling liquid in the cooling tube 26 circulates, thereby achieving the purpose of heat dissipation. This process ensures that the device is maintained at a suitable temperature during operation to prevent overheating.
Through this series of collaborative work, this intelligent surge protection device can cut off the circuit, keep apart the surge fast in the surge incident, has realized automatic repair and maintenance through intelligent internal design simultaneously, has ensured the high stability and the reliability of whole circuit system.
