Quick wiring construction method for multi-core control cable

Abstract

Disclosed is a quick wiring construction method for the multi-core control cable that comprises the following steps: matching equipment needing to be connected with the control cable; performing corresponding matching on the wiring terminal function and the terminal number of the matched equipment to form a wiring scheme of a control cable core; determining the number of wire cores of the control cable needing to be connected according to a matching result; and setting each wire core of the control cable connected to the equipment room to be a unique color, so that the terminal number, the terminal function and the wire core color of the equipment are matched and corresponding after the control cable is connected. According to the quick wiring construction method for the multi-core control cable, the control cable with the unique color core is adopted, the wiring scheme is deepened before construction, the unified matching principle of the terminal, the terminal definition and the core color is determined, and then the number of the cores of the control cable and the core color matching requirement are determined; an operator only needs to perform matching wiring on the colored wire core and the terminal without wire checking, so that the wiring efficiency and accuracy can be greatly improved.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a construction method for quick connection of multi-core control cables. Background technique [0002] Multi-core control cable wiring construction operations widely exist in various construction engineering fields, especially for projects with a relatively large proportion of equipment, the amount of secondary wiring work is very large, this work is time-consuming, highly professional, The characteristics of high professional quality of workers and high requirements for wiring accuracy have a great impact on project progress, commissioning efficiency, safety during commissioning, and even system operation stability in the later stage. [0003] The control cable wiring work exists between two devices (including boxes, cabinets, and panels). The construction steps are roughly divided into setting cable plates at both ends-calibration line-sleeve number pipe-wiring at both e...

Problems solved by technology

[0008] The function changes in the commissioning stage, maintenance and replacement after project operation, etc., may remove or adjust the control line. If the line number tube falls off in this link, it is very easy to cause confusion in the control line and re-calibrate the line.

[0009] The wire core adopts the wiring method of the control cable with digital marks. Although this method does not need time-consuming calibration, but in the construction stage, especially under the general lighting conditions of underground projects, the digital marks on the 1.0-1.5 cores are very small. It is very difficult to identify; the mark spacing of 500-1000mm can be laid in a larger power distribution cabinet, but it can be laid in a smaller control box, and there may be no digital marks in the peeling range of the control cable sheath; control cables After the wire cores are coiled, bound, and bundled in the cabinet, the numerical marks will basically be blocked, and it is difficult for engineers and technicians to check the correctness of the wiring

[0010] Color marking rule identification method, this method is theoretically feasible, but in the actual operation process, after the outer sheath of the control cable is stripped, after simple arrangement, the inner cores have already begun to diverge, and there is no guarantee that the sheath is stripped. At this time, there is a certain risk of error in inserting the wire number according to the established rules; with the increasing development of the manufacturing industry, the internal wire core arrangement of the control cables produced by various manufacturers is also different at present, and it is not completely "" Bullet shape”, therefore, the law of hierarchical recognition also has a certain risk of error
