[0037] Embodiment 2

[0038] like Figure 7-Figure 8 As shown, a surge protector proposed by the present invention, compared with the first embodiment, this embodiment introduces the structure of the alarm mechanism in detail;

[0039] Specifically, the alarm mechanism includes an alarm 603, a fault alarm component is arranged at the bottom of the alarm 603, and the fault alarm component is used to keep the entire circuit in a pass state and alarm after the tripping mechanism fails. A linkage alarm component is arranged on the side of the alarm 603, and the linkage alarm component is used to alarm after the tripping mechanism works. The fault alarm component includes a sensor line 602 arranged at the bottom of the alarm 603, and a controller 601 is arranged at one end of the sensor line 602 away from the alarm 603. The controller 601 detects the current in the circuit and then makes a judgment. If the current in the circuit is greater than the rated value, the circuit in the circuit is abnormal and not disconnected, it means that the tripping mechanism fails, and the controller 601 sends a signal, which is transmitted to the alarm 603 through the sensor line 602, so as to alarm. The alarm 603 is internally provided with a Bluetooth device, which can be connected to a mobile phone. The alarm 603 sends an alarm bell and an alarm signal at the same time. The alarm bell can remind people around the surge device that the surge device has a fault. If there is no one around, the alarm signal can also send information to the bound mobile phone to remind people to repair it. The linkage alarm component includes a slide rail 2 604 arranged on the inner side of the surge device housing 1, a slide rod 609 is slidably arranged on the inner side of the slide rail 2 604, a touch panel 605 is arranged on the side of the slide rod 609, a spring 3 606 is arranged on the side of the slide rod 609 away from the touch panel 605, a fixed block 2 607 is arranged on the end of the spring 3 606 away from the slide rod 609, a touch switch 608 is arranged on the side of the touch panel 605 away from the slide rod 609, and the touch switch 608 is arranged on the side of the alarm 603. When the touch panel 605 contacts the touch switch 608, the alarm 603 can also be activated, thereby driving the alarm to work and send out an alarm signal.

[0040] In summary, when the present invention is in use, when a circuit fails, the current in the circuit increases, and the increase in current increases the magnetic force of the electromagnet 506, so that the iron plate 515 moves, and drives the iron plate 515 and the electromagnetic plate 514 to be adsorbed together. At this time, the spring 2 505 is in a stretched state, and at the same time, the rotating rod 509 is driven to rotate around the connecting block 1 512 during the movement of the iron plate 515. When rotating, the rotating switch 510 will poke the fixed rod 508, and the protruding end of the fixed rod 508 will abut against the bottom of the rotating switch 510, so that it is separated from the guide block 1 511 and the guide block 2 513, so as to realize the power off of the circuit. At the same time, when the iron plate 515 moves, it drives the power block 516 to move, and the power block 516 will push the sliding rod 609 to move. The movement of the sliding rod 609 drives the touch panel 605 to move. When the touch panel 605 contacts the touch switch 608, the touch switch 608 will turn on the alarm 6 03, thereby driving the alarm to work and send out an alarm signal. The controller 601 detects the current in the circuit and then makes a judgment. If the current in the circuit is greater than the rated value, the circuit in the circuit is abnormal and has not been disconnected, it means that the tripping mechanism has failed. The controller 601 sends a signal, and the signal is transmitted to the alarm 603 through the sensor line 602, thereby giving an alarm. The alarm 603 is internally provided with a Bluetooth device, which can be connected to a mobile phone. The alarm 603 sends out an alarm and an alarm signal at the same time. The alarm can remind people around the surge device that the surge device has a fault. If there is no one around, the alarm signal can also be used to send information to the bound mobile phone to remind people to perform maintenance. After the maintenance personnel arrive, they pull the sliding switch 401. The sliding switch 401 drives the rotating rod 509 to rotate through the connecting shaft 402, thereby driving the rotating switch 510 and the fixed rod 508 to disconnect the circuit, thereby further protecting the circuit.
