Multi-channel current measuring device with leakage current measuring function

Abstract

The invention relates to the technical field of current measuring devices, in particular to a multi-channel current measuring device with a leakage current measuring function, which comprises a machine body and a measuring head, one side of the machine body is connected with a jacking seat through a pushing mechanism, the measuring head is mounted on one side, far away from the machine body, of the jacking seat, and pressing blocks are arranged on the upper side and the lower side of the measuring head. And the pressing blocks are connected with the outer wall of the machine body through extrusion mechanisms, first sliding rails are arranged on the two sides of the front face of the machine body, first sliding blocks are slidably connected into the first sliding rails, and one sides of the first sliding blocks are installed on the outer walls of the pressing blocks. According to the invention, the pressing blocks can clamp the wires, so that an operator can be connected with the measuring head without winding the wires one by one, the operator can detect the current conveniently, and the problem that when multiple sets of wires need to be measured at the same time, the wires need to be wound and taken down one by one, and the detection efficiency is reduced is effectively solved.

Description

technical field [0001] The invention relates to the technical field of current measurement devices, in particular to a multi-channel current measurement device with leakage current measurement function. Background technique [0002] In order to ensure the safety of the circuit, when the circuit is used for a long time, most of them need to use current measuring equipment to measure the circuit, detect whether there is leakage in the current, and prevent the early explosion of the electric detonator and other explosion accidents caused by stray current discharge. Current measurement equipment is a device with high sensitivity and multi-range protection circuit, and the current current measurement equipment basically has the function of detecting leakage current, so it can be seen that the existing multi-channel current measurement device with leakage current measurement function Basically meet the needs of people, but there are still some problems. [0003] Most of the exist...

Problems solved by technology

[0003] Most of the existing multi-channel current measurement is designed in one-piece structure. When using it, the operator needs to wind the copper wire on the wire on the measuring head to measure the current. When it is necessary to measure multiple groups of wires at the same time, it is necessary The wires are wound one by one, and when the measurement is completed, the wires need to be removed one by one, which greatly reduces the detection efficiency and affects the ease of use and applicability. Therefore, there is an urgent need for a new type of leakage current The multi-channel current measurement device with measurement function solves the above problems
