Description

Secondary cable laying device

technical field

The utility model relates to a secondary cable laying device, which belongs to the technical field of electrical installation. 1

Background technique

At present, the laying of secondary cables in substations mostly adopts the method of manual binding to bind the secondary cables on the cable support section by section. This laying method mainly has the following disadvantages: 1. Low work efficiency. For example, it takes about 15 people to lay a conventional 110kV substation, and the laying is completed in 4 working days. The cables to be laid are provided with a row of cable brackets every 60-80 cm in the cable trench, and each worker is responsible for 2-4 rows of cable brackets. Multiple secondary cables need to be laid side by side on each cable support, and each secondary cable is bound on the cable support one by one, and conventional laying is time-consuming and laborious.

2. There are high requirements for cable laying operators, otherwise the laying effect will be poor. Inexperienced operators may have problems such as loose cable bundles, sagging cables between brackets, crossed cables, and chaotic wiring when laying cables, which will cause great trouble for later troubleshooting.

3. The cable is easily damaged by external force, which affects the safe operation of the equipment. The secondary cable is directly mounted on the cable support, which is an angle steel structure. The position where the cable may be touched during dragging or daily operation will easily cause the cable insulation to wear out, reduce the service life of the cable, and easily cause safety hazards.

4. It is easy to cause waste of secondary cables. When laying, the length of the cable is not enough or the position of the on-site equipment is changed. The length of the cable originally laid is not enough, and the cable cannot be withdrawn due to the binding of the binding wire, resulting in a waste of resources.

When in use, the cable fixing block 2 is first installed on the cable bracket 1, and then a plurality of cables 10 are placed in the slots 3 of the cable fixing block 2 in sequence, and inserted The slot 3 clamps the cable 10. Since the inner surface of the slot 3 is arc-shaped, the outer wall of the cable 10 can be closely attached to the slot 3 to fix the cable 10. The above structural features and laying process can achieve the following advantages :

1. Avoid the wear of the cable sheath that exists in the iron wire binding and fixing, prolong the service life of the cable, and reduce potential safety hazards;

2. Since there are multiple slots in the length direction of the cable fixing block, multiple cables can be placed along the length direction of the cable fixing block, which can not only improve work efficiency, but also make cable laying neat;

3. The cable fixing blocks are inserted in sequence from bottom to top, and multiple layers of cables can be installed on a cable bracket, so that the cables are arranged tightly and the wiring is neat, which brings a lot of convenience for later troubleshooting.

In summary, the utility model has a reasonable structural design and has a good application prospect in the electric power field.
