Current device convenient for circuit detection

Abstract

The invention relates to the field of current devices, in particular to a current device convenient for circuit detection. The current device comprises a detection main body, a fixing mechanism, a winding mechanism, a limiting mechanism, a folding mechanism and a clamping mechanism, the fixing mechanism is arranged so that the detection main body can be conveniently carried on the body of a user and prevented from being lost, the winding mechanism is arranged so that the cable can be conveniently and regularly stored in the detection main body, the cable is prevented from being scattered outside and scratched and damaged, and therefore the attractiveness of the detection main body is improved. Through the arrangement of the limiting mechanism, winding and unwinding of the cable can be limited and fixed, the situation that the cable with the redundant length accidentally slides out of the detection body is avoided, through the arrangement of the folding mechanism, the lighting part canbe conveniently opened in a dark corner, maintenance personnel can be conveniently assisted in finding out the part needing to be inspected, and therefore the maintenance efficiency is improved; and through the arrangement of the clamping mechanism, a closed loop can be conveniently formed for a line needing to be overhauled, and the clamping and fixing part can clamp and fix different parts or cables.

Description

technical field [0001] The invention relates to the field of galvanometers, in particular to a galvanometer convenient for circuit detection. Background technique [0002] The function of the galvanometer is to provide current to the inductive current load according to the current command, which is essentially a controlled current source. The current meter is generally composed of four parts: power supply, power electronic circuit, inductive load, and controller, and adopts closed-loop control of output current. [0003] The ammeter is generally used to judge the direction and damage of a section of the line. When it is necessary to overhaul the incoming cables inside the car, because most of the traditional detection ammeters are not equipped with portable fixed parts, it is not convenient for maintenance workers. Carry it to shuttle inside the car in a small space, and most of the cables for the general detection current meter are external, making the cables easy to be sc...

[0003] The ammeter is generally used to judge the direction and damage of a section of the line. When it is necessary to overhaul the incoming cables inside the car, because most of the traditional detection ammeters are not equipped with portable fixed parts, it is not convenient for maintenance workers. Carry it to shuttle inside the car in a small space, and most of the cables for the general detection current meter are external, making the cables easy to be scratched or hung up by external sharp objects, thus hindering the maintenance process and increasing additional usage costs
