Core wire checking apparatus and method

Abstract

The invention provides a core wire checking apparatus and method. The apparatus is composed of an apparatus host and an apparatus auxiliary unit. The apparatus host consists of a host module and a plurality of first current detection modules connecting a plurality of cable core wires. The apparatus auxiliary unit includes an auxiliary unit module and a plurality of second current detection modules connecting a plurality of cable core wires. The auxiliary unit module controls the plurality of first current detection modules, the plurality of second current detection modules, and the cable wire cores to form a current loop, thereby obtaining detection results of current flowing directions of the plurality of first current detection modules and the plurality of second current detection modules; and the host module analyzes and determines state checking results of the plurality of cable core wires according to the detection results of current flowing directions of the plurality of first current detection modules and the plurality of second current detection modules. Therefore, the checking process of the cable core wires is simplified, so that the time is saved substantially and the work efficiency is improved to a certain extent; and the cable core wire checking becomes accurate.

Description

technical field [0001] The invention relates to the field of instruments and meters, in particular to a core wire checking device and method. Background technique [0002] With the development of science and technology, a large number of multi-core secondary cables are used in conventional substations in my country as signal transmission media between equipment control systems such as protection devices and measurement and control devices. During the actual construction and wiring, electric workers need to test the insulation and continuity of each core wire in the multi-core secondary cable, especially to confirm whether the cable wire number corresponding to each core wire corresponds to the two ends, so as to ensure that the secondary The correctness of secondary equipment signal and control circuit wiring. The correctness of secondary cable wiring plays a vital role in ensuring the reliable operation of the entire electrical system. [0003] The verification workload o...
