Abstract

The invention provides a cable core verifying device which belongs to the technical field of cable construction tools. The device comprises a box body, a controller and an indicator, wherein the controller and the indicator are arranged in the box body. Two ends of the box body are correspondingly provided with the same number of binding posts. The controller comprises a power supply and a controlswitch. The contacts of the control switch are connected with the binding posts through wires. The indicator is connected in series with the wires of the control switch and the power supply. The cores of two plugs of a cable to be verified are respectively connected with the binding posts on two ends of the box body. The cable cores on both ends of the box body are verified in sequence through the control switch. If the same core is used, the circuit is connected, and the indicator indicates accurate verifying of the cable cores. According to the invention, a plurality of cable cores are verified at one time; the working efficiency of cable core verifying is effectively improved; cable core verifying can be conveniently carried out in various construction places; the correctness of core verifying is improved; the construction progress is quickened; and follow-up secondary debugging can be carried out smoothly.

Description

technical field [0001] The invention belongs to the technical field of cable construction tools, and more specifically relates to a cable core calibration device. Background technique [0002] The secondary installation of the substation mainly involves the laying and installation of the secondary cables. The secondary cable laying is an important construction process of the electrical construction project of the substation, which affects the construction process of the entire electrical project and the level of secondary construction technology. The secondary cable laying process is complicated, the wiring is cumbersome, and it is easy to have wrong connections and missing connections. Therefore, before the secondary cable laying work on site, it is often necessary to carry out the core calibration work of the secondary cable. Due to the large workload of secondary cable laying, the calibration work of secondary cables is very cumbersome, and the number of secondary cable ...
