Problems solved by technology
[0003] The alarm mode of the lightning protection module is a dry contact alarm mode and an active alarm mode, and most of the lightning protection modules adopt a dry contact alarm mode, and a small part of them adopt an active alarm mode. Cost, regardless of the above-mentioned alarm methods, most of them will only use one of them, so when the circuit is changed, only different types of lightning protection modules can be replaced, which is not flexible enough in use; another, the existing technology The overall structure of the lightning protection module is relatively complex, and the overall volume is large, which seriously affects the installation and maintenance of the lightning protection module

The invention discloses a lightning protection module with a plurality of alarming modes, which comprises a shell and a frame arranged inside the shell. One side of the frame is provided with a varistor and the other side of the frame is provided with a sliding block arranged on the frame in a sliding manner. A spring is arranged between the sliding block and the frame, and the two ends of the frame are provided with an input pin and an output pin respectively wherein the input pin is electrically connected with the input electrode of the varistor through a conductive sheet. The conductive sheet is arranged on the sliding block. The output pin is electrically connected with the output electrode of the varistor. The varistor is provided with an active alarming terminal. A first dry contact alarm pin, a second dry contact alarm pin and a third dry contact alarm pin are arranged at the lower end of the frame in the length direction of the frame. The sliding block is provided with a top block. The module of the invention is convenient for installation and maintenance, and adopts the effective combination of active alarming and dry contact alarming, making it suitable for use by various users in their flexible applications.
Description
technical field [0001] The invention relates to the technical field of lightning protection modules, in particular to a lightning protection module with multiple alarm modes. Background technique [0002] Surge protector is an indispensable kind of lightning protection for electronic equipment. Its main function is to protect equipment from being damaged by strong lightning current. Among them, the lightning protection module plays a central role in the surge protector. It is very important to ensure that the lightning protection module itself is intact and works normally, so most of the various lightning protection modules on the market are equipped with alarm functions. [0003] The alarm mode of the lightning protection module is a dry contact alarm mode and an active alarm mode, and most of the lightning protection modules adopt a dry contact alarm mode, and a small part of them adopt an active alarm mode. Cost, regardless of the above-mentioned alarm methods, most of ...
