Abstract

The invention provides a cable secondary line checking instrument, which belongs to the technical field of power cable checking and comprises a host and a slave which are respectively connected with two ends of a to-be-checked cable. Each of the host and the slave comprises a machine body, a wire core wiring module and a wire core display module; the wire core display module comprises a liquid crystal screen arranged on the machine body; the machine body comprises a first machine body on the host and a second machine body on the slave; the wire core wiring module comprises a first wiring port arranged on the first machine body and a second wiring port arranged on the second machine body; one end of a to-be-checked cable is connected to the first wiring port, the other end of the to-be-verified cable is connected to the second wiring port, information of the to-be-checked cable is edited through the host and sent to the slave, and the slave receives the information of the to-be-checked cable and verifies the to-be-checked cable. Whether the to-be-checked cable is electrified or not and whether the cable secondary wire can be calibrated or not can be visually determined, and the wire core of the cable secondary wire can be rapidly and automatically determined in a large scale.

Description

technical field [0001] The invention relates to the technical field of power cable calibration, in particular to a cable secondary line calibration instrument. Background technique [0002] In the power system site, the current method commonly used for calibration work is to use a multimeter (or light) to measure the on-off and walkie-talkie to assist in calibration. At present, similar products on the market use the method of measuring high and low levels to distinguish different lines. They can only detect whether they are unobstructed, but they cannot know the name of the line, and cannot effectively identify live cables, which will bring certain hidden troubles. Through consultation and investigation of domestic units in the same industry, it is found that most units use the on-off gear of the multimeter to ground or the on-off of the spare core to determine the correctness of the core. There is no effective means for simply, quickly and accurately determining the corre...
