Problems solved by technology

If the production of the control cable head is not standardized, the wiring process is not beautiful, the cable plate is not clearly marked, and the fixation is not neat, it will not only affect the aesthetics of the process, but also affect the construction quality of the substation. Various construction difficulties in the secondary wiring process, it is very important to improve the quality and technological level of the secondary wiring of the substation

Embodiment

[0045] Example: A layered stripping arrangement method for secondary wiring of a cable, the specific steps are as follows:

[0046] A. Construction preparation:

[0047] 1) Prepare consumable materials and construction tools required for the construction of secondary wiring;

[0048] 2) Check the construction drawings and cable inventory, check the specifications and models, and check the appearance of no damage;

[0049] B. Operation steps:

[0050] 1) Laying cables:

[0051] a. Divide the cables on the left and right wiring sides, and pass the cables through the cabinet one by one; strip off the outer skin and steel armor of the cable near the plane of the cable hole in the screen cabinet;

[0052] b. Weld the steel armored ground wire, and wrap the welding place neatly with insulating self-adhesive tape;

[0053] c. Fix the cables on the horizontal support of the screen cabinet and arrange them, and record the arrangement order;

[0054] 2) Cable head production:

[0055] a. Strip the cab...

Abstract

The invention discloses a cable secondary wiring layered peeling arrangement method. The method comprises the steps of construction preparation, cable laying, cable head manufacturing, cable signboardfixing, core wire arrangement and cable checking and wiring. According to the invention, more cables can be arranged in a narrow space, screen front wiring in a traditional mode is changed into screen back wiring, and the speed, the quality and the process of secondary wiring are improved; the back surface of a screen is attractive in routing process, reasonable in routing and elegant; by means of the method, the construction period is shortened, cost is reduced, and the method has good social and economic benefits and is easy to popularize.

Description

1. Technical Field: [0001] The invention relates to a secondary wiring link in the construction process of a generator set and a substation, in particular to a layered stripping arrangement method for the secondary wiring of a cable. 2. Background technology: [0002] Secondary wiring is an important link in the construction of substations, and it is also a highlight of the substation process. High-efficiency secondary wiring can effectively improve the construction progress in the middle and late stages of the project. At this stage, the voltage level and automation degree of the power system are getting higher and higher, especially the wide application of microcomputer protection and comprehensive automation systems, which makes the number of substation cables more and more. The control cables are as many as tens of thousands of meters, ranging from hundreds of cables. , As many as thousands, and there are tens of thousands of cores. If the control cable head is not made stan...
