Detailed Description

The following detailed description takes the surge protector as an example, wherein the specific structure of the release is shown at the same time, and the release structure is not described as an independent embodiment, specifically as follows:

as shown in fig. 1, a surge protector includes three lightning protection modules 10, wherein each lightning protection module 10 is connected with a release 20 corresponding to the lightning protection module.

As shown in fig. 2, the lightning protection module 10 on the left side of fig. 1 is used to show the specific structure of the trip unit 20, and the trip unit 20 includes a rotating shaft 21, a trip elastic sheet 22, a power spring 23, a connecting shaft 24, a guide rod 25, an alarm 26 and a resistance spring 27.

One end 22a of the tripping elastic sheet is hinged on the revolving shaft 21, one end 22a of the tripping elastic sheet is connected with the input electrode 11 through the flexible conductor 28, and the other end 22b of the tripping elastic sheet is welded with the lightning protection module electrode 12 through the low melting point material.

Wherein the flexible conductor 28 is a conductive braided strap.

The connecting shaft 24 is positioned below the right side of the rotating shaft 21 close to the alarm piece 26, one end of the power spring 23 is connected to the tripping elastic sheet 22, and the other end of the power spring 23 is fixed on the connecting shaft 24.
