Description

Technical Field

[0001] The utility model belongs to the technical field of cables, and in particular relates to a wind turbine generator cable with a protective structure. Background Art

[0002] Cables are typically made up of several or several groups of conductors (at least two in each group) twisted together into a rope-like structure. Each group of conductors is insulated from each other and often twisted around a central core. The entire structure is covered with a highly insulating sheath. Cables are characterized by internal conduction and external insulation, making them widely used in power transmission for wind turbines.

[0003] Existing cables mainly rely on their own materials to achieve protective effects, and add steel belt armor inside to improve strength to protect the internal battery cells. However, the outermost insulation layer still has the risk of breakage and damage, especially in the bending parts, joints and parts in contact with other structures. Therefore, there are great limitations in actual use and there is room for improvement. Utility Model Content

[0004] The purpose of the present utility model is to provide a wind turbine cable with a protective structure to solve the problem that the protective effect of the existing cables mentioned in the above background technology is insufficient.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a wind turbine generator cable with a protective structure, comprising an outer jacket; an insulating sleeve, which is covered by the outer jacket, and a conductive structure is arranged inside the insulating sleeve; a protective component, which is composed of an inner reinforcement and an outer protective part, wherein the inner reinforcement is arranged between the insulating sleeve and the outer jacket, and is wrapped around the surface of the insulating sleeve, thereby increasing the strength of the insulating sleeve, and the outer jacket can hide the inner reinforcement to avoid direct exposure to the outside and affecting the service life of the reinforcing steel wire; the outer protective part is covered on the outside of the outer jacket, and the two ends of the outer protective part are locked on the outer jacket to achieve position limitation. During use, the outer protective part can be moved to the designated area to be protected to protect part of the cable area.

[0006] Preferably, the surface of the insulating sleeve is provided with a plurality of non-intersecting grooves, which are spirally distributed on the insulating sleeve. The inner reinforcement is a reinforcing steel wire embedded in the groove. The outer sleeve is hot-melt attached to the outside of the insulating sleeve and the reinforcing steel wire, thereby forming a whole with the insulating sleeve. During use, the strength of the insulating sleeve can be increased by the reinforcing steel wire.

[0007] Preferably, the two ends of the reinforcing steel wire and the two ends of the insulating sleeve are in the same plane, thereby achieving comprehensive protection of the insulating sleeve, and the inner diameter of the outer sleeve is equal to the outer diameter of the insulating sleeve, thereby achieving comprehensive sleeve installation.

[0008] Preferably, the outer protective part includes a protective sleeve mounted on the outer jacket, and an open groove is provided at a radial position on the surface of the protective sleeve, which can be conveniently mounted on or removed from the outer jacket through the open groove. The open groove is corrugated, so that its own length can be adjusted according to protection requirements.

[0009] Preferably, both ends of the protective sleeve are in contact with the surface of the outer jacket, and locking hoops are provided at both ends of the protective sleeve. The two ends of the locking hoops are fixed by twisting, so as to lock the protective sleeve on the outer jacket and prevent the protective sleeve from detaching from the designated protection area.

[0010] Preferably, the conductive structure includes a plurality of battery cells and a filling layer for filling the space between the battery cells and the filling layer.

[0011] Preferably, a honeycomb hole is opened at the center of the end of the filling layer, and the honeycomb hole does not contact the battery core. The honeycomb hole can reduce the weight of the filling layer, thereby offsetting the weight of the entire cable caused by the arrangement of the reinforcing steel wire.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] Through the designed protective component, the strength of the outermost insulating sheath of the cable can be improved, greatly reducing the risk of breakage. At the same time, protection can be provided on the areas on the outside of the cable that are prone to wear, thereby improving the protective effect of the cable. The protective component has a simple structure and high flexibility, which improves the problem of insufficient protective effect of existing cables. BRIEF DESCRIPTION OF THE DRAWINGS
