Surge protector action signal detection method and device and surge protector

Abstract

The invention relates to the field of surge protector equipment, in particular to a surge protector action signal detection method and device and a surge protector. The invention provides a surge protector action signal detection method. The method comprises the following steps: acquiring loss information of an optical fiber where a surge protector is located in real time; and according to the loss change condition of the optical fiber, action information that the optical fiber deforms under the action of the thermal tripping assembly and the backup protection assembly of the surge protector is obtained. On the premise that the surge protector does not need to be powered by an external circuit or a built-in power supply, the transmission of the action signal of the surge protector can be realized.
