Abstract

The invention discloses a shielded box capable of carrying out lightning arrester detection. The shielded box comprises three parts, i.e., a shielded box body, a lightning arrester and a metallic shield socket, wherein the shielded box body is mounted on the outer wallboard of a car, and is fixedly connected to a cabin through bolts; the lightning arrester is mounted in the shielded box body; a remote control measurement terminal of the lightning arrester is introduced outside the shielded box body, and is connected in the metallic shield socket mounted outside the shielded box body by virtue of a cable. The shielded box disclosed by the invention meets requirement of a square cabin 60dB on electromagnetic shielding and also prevents induction lightning voltage in the cabin.

Description

technical field [0001] The invention relates to the technical field of lightning protection, in particular to a shielding box capable of detecting lightning arresters. Background technique [0002] Currently used shelter power supply wall boxes, shelters without shielding requirements generally open holes directly on the wall plate, install the arrester (overvoltage protector) on the panel, and the arrester has a display window, you can directly see the indication of the arrester state, to know whether the arrester is invalid at any time; shelters with shielding requirements are generally installed with a transfer shielding box on the wall, and the arrester is installed in the box. It is impossible to directly see whether the arrester is invalid, and the arrester cannot be replaced in time, which affects the lightning protection of the shelter. Effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a shielding ...
