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
The present invention relates to anti-thunder technical field, particularly a kind of shielding case body carrying out arrester checks.
Background technology
The shelter power supply wall box of current use, the shelter of unshielded requirement is generally direct perforate on wallboard, and be arranged on panel by lightning arrester (overvoltage protection device), lightning arrester has display window, directly can see the indicating status of lightning arrester, understand lightning arrester at any time and whether lost efficacy; There is the shelter of shielding requirements to be generally that switching shielded box is installed on wallboard, lightning arrester is arranged in case, whether cannot loses efficacy by direct viewing lightning arrester, and lightning arrester can not be changed in time, and affected shelter lightning protection effect.
Summary of the invention
Technical matters to be solved by this invention be for existing shielding shelter cannot the indicating status of direct viewing lightning arrester time Problems existing and a kind of shielding case body carrying out arrester checks is provided.
Technical matters to be solved by this invention is achieved through the following technical solutions:
Carry out a shielding case body for arrester checks, it is characterized in that: it comprises shielding case body, lightning arrester, metallic shield socket; Shielding case body is arranged on car exterior panel, be bolted to connection with cabin body, lightning arrester is arranged in shielding case body, and the Long-distance Control measurement terminal of lightning arrester is drawn out to outside shielding case body, and is connected to by cable in the metallic shield socket be arranged on outside shielding case body.
Described shielding case body becomes a rectangular parallelepiped by Plate Welding, installs combine wire mesh pad at shielding case body and car wall binding site.
Described lightning arrester is made by zinc oxide material; that protection electrical equipment endangers from high transient overvoltage and limits a kind of electrical equipment that time of afterflow also often limits afterflow assignment; lightning arrester is connected between electrical network wire and ground wire usually, is sometimes also connected between electrical equipment winding side or wire.
Described metallic shield socket is the Socket device for electrical equipment with shielding action be made by metal shell.
The present invention compared with prior art has following features:
A kind of shielding case body carrying out arrester checks provided by the invention, installs simple, not only can meet shelter 60dB electromagnetic shielding requirements, immediately can understand again the duty of lightning arrester, prevents lightning voltage from introducing in cabin, damage equipment.
Be further described below in conjunction with the detailed construction of the drawings and specific embodiments to invention.

Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth embodiments of the present invention further.
Carry out a shielding case body for arrester checks, it is characterized in that: it comprises shielding case body 1, lightning arrester 2, metallic shield socket 3; Shielding case body 1 is arranged on car exterior panel, be bolted to connection with cabin body, lightning arrester 2 to be arranged in shielding case body 1, and the Long-distance Control measurement terminal of lightning arrester 2 is drawn out to outside shielding case body 1, and is connected to by cable in the metallic shield socket 3 be arranged on outside shielding case body 1.
Described shielding case body 1 becomes a rectangular parallelepiped by Plate Welding, installs combine wire mesh pad at shielding case body and car wall binding site.
Described lightning arrester 2 is made by zinc oxide material; that protection electrical equipment endangers from high transient overvoltage and limits a kind of electrical equipment that time of afterflow also often limits afterflow assignment; lightning arrester is connected between electrical network wire and ground wire usually, is sometimes also connected between electrical equipment winding side or wire.
Described metallic shield socket 3 is the Socket device for electrical equipment with shielding action be made by metal shell.
principle of work of the present invention and using method are:during use, first shielding case body 1 is arranged on car exterior panel, be fixedly connected with cabin body, lightning arrester 2 is arranged in shielding case body 1, the Long-distance Control measurement terminal of lightning arrester 2 is drawn, and be connected to the shielding socket 3 be arranged on outside shielding case body 1 by cable, use pre-test socket pins 1,2, if be in conducting state to represent that lightning arrester lost efficacy, should change immediately.Zinc oxide surge arresters according to the method described above, both can meet shelter 60dB electromagnetic shielding requirements, immediately can understand again the duty of lightning arrester, prevented lightning voltage from introducing in cabin, damage equipment.
More than show and describe ultimate principle of the present invention, principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not only restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof
