Detailed Description

The present invention will be more clearly and completely described below by way of examples and with reference to the accompanying drawings, but the present invention is not limited thereto.

As shown in fig. 1 and fig. 2, the present embodiment provides a cable abandoned line processing method, where a cable abandoned line 20 is inserted into a cable slot on a cable tray, two ends of the cable abandoned line 20 are exposed at two ends of the cable slot, and the cable abandoned line processing method includes the following steps:

s1, performing insulation sealing treatment on one end of the cable abandoned line 20;

and S2, grounding the wire core 201 at the other end of the cable abandoned wire 20.

One end of the cable abandoned line 20 is subjected to insulation sealing treatment, and the other end of the cable abandoned line is subjected to grounding treatment, so that abnormal sound caused by the influence of an external magnetic field on the abandoned cable can be effectively improved; on the other hand, potential safety hazards caused by the abandoned cable during the subsequent cabling and the operation of the ship can be effectively eliminated.

As will be understood with reference to fig. 2, in step S1, the cable discard 20 is subjected to insulation sealing processing using the heat-shrinkable tube 10. In step S1, the core 201 of the cable abandon line 20 is insulated, and then the heat shrink sleeve 10 is sleeved outside the cable abandon line 20 to perform a secondary insulation process. Wherein, adopt heat shrinkage bush to abandon line 20 to carry out insulating seal to the cable and handle, have convenient construction, insulating effectual advantage sealed. The insulation processing is carried out on the wire core 201 of the cable abandoning wire 20 firstly, and then the secondary insulation processing is carried out on the outside of the cable abandoning wire 20, so that the insulation processing of the cable abandoning wire 20 is more reliable by adopting the method, and the insulation effect cannot be influenced even if the heat-shrinkable sleeve 10 on the outside is damaged.

In this embodiment, when the cable waste wire 20 is subjected to insulation sealing treatment, an appropriate heat-shrinkable tube 10 is selected, and the inner diameter of the heat-shrinkable tube 10 is slightly larger than the outer diameter of the cable waste wire 20, that is, the heat-shrinkable tube 10 can be smoothly sleeved into the cable waste wire 20 from the end of the cable waste wire 20. Then cutting the length of the heat-shrinkable sleeve 10 according to the requirement, sleeving the heat-shrinkable sleeve 10 on the cable abandon line 20, uniformly heating the heat-shrinkable sleeve 10 by using heating tools such as a hot air gun and the like, and heating and shrinking the heat-shrinkable sleeve 10 and fixing the heat-shrinkable sleeve with the cable abandon line 20. The insulation treatment of the wire core 201 can be an electrical tape, and the heat-shrinkable sleeve 10 can also be adopted.

As will be understood with continued reference to fig. 2, a shielding layer 30 is provided on the outside of the core 201 of the cable drop 20. The core 201 at the end of the cable waste wire 20 is fixed with the shielding layer 30 by soldering. The shielding layer 30 is disposed outside the wire core 201, so as to prevent the waste cable from interfering with other devices due to the influence of the surrounding environment, and to provide a ground protection function. The wire core 201 and the shielding layer 30 are fixed by brazing, so that the shielding layer is tightly connected with the end part of the wire core 201, and a good shielding effect is realized.

In step S2, one end of the cable stub 20 where the distribution room is located is grounded. After one end of the cable waste wire 20 is grounded, the end of the cable waste wire 20 is insulated and sealed. Wherein, because the electricity distribution room is equipped with the PE row that is used for ground connection, conveniently ground connection can improve the work efficiency of ground connection. The end part of the cable abandoning wire 20 is insulated and sealed after being grounded, so that the insulation effect of the cable abandoning wire 20 is improved, and the safety and reliability of the abandoned cable are further improved.

In this embodiment, the grounded end of the cable abandonment line 20 is connected to the grounded PE row of the distribution room, or the grounded end of the cable abandonment line 20 is pulled back to the cable tray and the end is connected to the ground rod 40. Before grounding, the heat-shrinkable tube 10 is sleeved in the cable abandoned line 20, and after grounding, one grounding end is subjected to sealing insulation treatment by the heat-shrinkable tube 10.
