[0002] Energy storage cables are used to connect battery clusters, or the DC side cables between battery clusters and converters. They are primarily used in power storage systems and play a vital role in modern energy systems. With the widespread application of renewable energy sources such as wind and solar energy, energy storage technology has become a key technology for balancing supply and demand and improving energy efficiency. As an indispensable component of energy storage systems, the performance of energy storage cables directly affects the stability and safety of the entire system. In general, as one of the key components in energy storage systems, the quality and performance of energy storage cables are crucial to the reliability and safety of the entire system. When selecting and using energy storage cables, factors such as their electrical performance, mechanical properties, and environmental adaptability should be fully considered.

[0003] At present, the insulation and protection performance of energy storage cables is relatively low, especially in cold areas with complex construction site environments. The protective sheath on the outside of the cable is not enough to protect the cable core inside the cable body, causing damage to the cable core and thus affecting its service life.

[0004] In view of this, this application is hereby filed. Utility Model Content

[0005] The purpose of the present utility model is to provide an energy storage cable with a thermal insulation structure to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the utility model provides an energy storage cable with a thermal insulation structure, which includes a protective cover and a wire core.

[0007] The protective cover is a cylindrical structure as a whole, with a placement groove on its outer surface. A wire core is installed inside the placement groove, and the wire core is wrapped with an insulating cover on the outside. An insulation cover is installed on the outside of the protective cover, and the inner interlayer of the insulation cover is filled with rock wool insulation material.

[0008] In one embodiment, the placement grooves are arranged in at least six groups in a circular array and are spaced apart from each other. The placement grooves are generally U-shaped, and the arcuate surface thereof is close to the center of the protective cover.

[0009] In one embodiment, an opening is provided at the top of the insulation sleeve, and a protective groove is provided inside the insulation sleeve. The internal structure and size of the protective groove are matched with the protective sleeve. The inner wall surface of the insulation sleeve is installed with abutment strips in a circular array, and the surface of the abutment strips facing the wire core is an arc-shaped groove.

[0010] In one embodiment, an installation groove is opened at the arc end of the placement groove, and the installation groove is also a U-shaped structure. A temperature measuring optical fiber is placed inside the installation groove, and the temperature measuring optical fiber is installed and connected to the external temperature control unit. The outside of the temperature measuring optical fiber is protected by a mesh layer, and the number of the temperature measuring optical fibers is consistent with the number of wire cores.

[0011] In one embodiment, the protective cover is entirely made of rubber, and a shielding layer is bonded to the outside of the thermal insulation cover.

[0012] In one embodiment, the shielding layer is covered with a waterproof layer, and the two are bonded and installed by an adhesive.

[0013] In one embodiment, an outer protective layer is provided on the exterior of the waterproof layer, and the outer protective layer and the waterproof layer are bonded and installed by an adhesive.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. By pressing the wire core tightly into the placement groove and installing an insulation sleeve on the outside of the protective sleeve, the protection and insulation effect of the wire core can be improved. By pressing the wire core tightly into the placement groove, wrapping the protective sleeve from both sides, and inserting the abutment strip into the placement groove, the arc-shaped groove abuts against the outer side of the wire core, providing further insulation protection effect for the wire core, which helps to improve the stability of the wire core.

[0016] 2. Before placing the core, pre-install the temperature measuring optical fiber into the installation groove. After the core is placed, the two are in contact with each other, which helps to perform temperature control and protection operations on the entire cable component.
