[0014] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0015] According to the surge protection device of the embodiment of the utility model, Figure 1 As shown, it includes an outer shell 10 and a lightning protection mechanism 20; a connector 11 is opened on the inner side of the outer shell 10; the lightning protection mechanism 20 is arranged in the outer shell 10 to prevent lightning current from affecting the circuit; wherein, the connector 11 detachably clamps the outer shell 10 on the guide rail, because the common lightning protection devices now require the connection end of the protection device to be connected to the guide rail in the box that matches its appearance, and the connection needs to be pushed in from one end of the guide rail, which is more complicated to operate, and it is not convenient to remove the protection device from the guide rail during daily maintenance and replacement. The connector 11 with detachable characteristics solves the problem of complex installation of surge protection devices in the box in the prior art.

[0016] When implementing it, Figure 1 As shown, the lightning protection mechanism 20 includes a discharge component 21 and a resistance component 22; one end of the discharge component 21 is connected to the power equipment, and the other end is connected to the ground wire to introduce the arc generated by the lightning current into the ground wire; the resistance component 22 is arranged on the outer shell 10 and connected to the power equipment to adjust the voltage generated by the lightning current to a preset value. The resistance component 22 used in this surge protection device is a high-sensitive resistor, which has a better effect in preventing lightning damage.

[0017] When implementing it, Figure 2As shown, the connecting member 11 includes a connecting groove 111 and a buckle 112; the connecting groove 111 is opened on the inner side of the outer shell 10 to clip the outer shell 10 on the guide rail; the buckle 112 is arranged in the connecting groove 111 to detachably fix the outer shell 10 on the guide rail. During installation, it is only necessary to press the buckle 112 and push the connecting groove 111 into the guide rail. When the connecting groove 111 is clipped into the guide rail, release the buckle 112, and the fastening part in the connecting groove 111 connected to the buckle 112 will pop out and fix the outer shell 10 on the guide rail. If the outer shell 10 needs to be removed, it can be removed by pressing the buckle 112 in the same way, which is convenient to operate.

[0018] In specific implementation, the preset value is a voltage value that is less than the maximum voltage of the power equipment. The surge protection device mainly prevents lightning from affecting the corresponding power equipment by adjusting the voltage, and this can be avoided by adjusting the high voltage value it generates to a normal value.

[0019] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
