At present, the fields of new energy and renewable energy are continuously developed, and the energy storage industry is also greatly developed. At present, batteries are a common energy storage mode in the market, and a large number of battery connecting cables are also applied to an energy storage system. The energy storage cable refers to a direct-current side connecting cable connected between the battery clusters and the current transformer, and serves as a blood vessel and a nerve of the energy storage system. However, existing energy storage cables typically employ copper core stranded conductors, conventional PVC extrusion insulation and jacket layers. The cable adopting such a structure has the following disadvantages: poor bending performance and overload performance, acid and alkali resistance, salt fog resistance, ultraviolet resistance, high and low temperature resistance and poor flame retardant performance, and can generate chlorine-containing toxic gas during combustion.

The utility model aims to solve the problems in the prior art, and provides a soft-grade fireproof flame-retardant energy storage cable which has good bending performance, acid and alkali resistance, salt fog resistance, ultraviolet resistance, low smoke halogen-free flame retardance and the like, and has good overload performance at the working environment temperature of between-40 ℃ and 150 ℃.
In order to achieve the above purpose, the present utility model adopts the following technical scheme:
a soft-grade fireproof flame-retardant energy storage cable comprises a copper wire bundle stranded conductor, an insulating layer, a shielding layer and an outer protective layer which are sequentially arranged, wherein the copper wire bundle stranded conductor is a tinned copper wire stranded soft-structure conductor, the insulating layer is a ceramic silicon rubber insulating layer, and the material can form a compact ceramic structure when meeting high temperature, so that the cable core has good effects of resisting mechanical impact and isolating external high temperature; the shielding layer is a tinning braided shielding layer, and the outer protective layer is a 150 ℃ irradiation crosslinking polyolefin outer protective layer.
Preferably, the tinning braided shielding layer is a tinning wire braided layer with the braiding density being more than or equal to 80%, and the influence of electromagnetic interference generated in electric energy transmission on the whole electromagnetic assembly or the electric circuit can be effectively prevented.
Preferably, the 150 ℃ irradiation crosslinking polyolefin outer sheath is made of 150 ℃ irradiation crosslinking low smoke halogen-free flame retardant polyolefin material, and has good properties of salt spray resistance, acid and alkali resistance, air aging resistance, halogen-free flame retardance and the like.
Compared with the prior art, the utility model has the beneficial effects that:
the conductor of the soft-grade fireproof flame-retardant energy storage cable adopts the tinned copper wire bundle stranded soft conductor, and has stable structure, small bending radius and excellent conductive performance. The insulating layer is made of ceramic silicon rubber material, the working temperature of the insulating layer can reach the range of-40 ℃ to 150 ℃, and a ceramic shell can be formed when the insulating layer is subjected to high temperature above 600 ℃, so that the cable core can be effectively protected against mechanical impact, and meanwhile, the damage of external high temperature to the cable core is resisted. The outer sheath is made of 150 ℃ irradiation crosslinking low-smoke halogen-free flame-retardant polyolefin material, so that the overall salt spray resistance, acid and alkali resistance, air aging resistance, halogen-free flame retardance and other performances of the cable are effectively improved, and the cable passes the bunched combustion flame retardance A-level test.

Fig. 1 is a schematic structural diagram of a soft-class fireproof flame-retardant energy storage cable according to the present utility model;
description of the embodiments
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.
Referring to fig. 1, a soft-grade fireproof flame-retardant energy storage cable comprises a copper wire bundle stranded conductor 1, an insulating layer 2, a shielding layer 3 and an outer protective layer 4 which are sequentially arranged, wherein the copper wire bundle stranded conductor is a tinned copper wire stranded soft structure conductor 1, the insulating layer is a ceramic silicon rubber insulating layer 2, and the material can form a compact ceramic structure when meeting high temperature, so that the cable core has good effects of resisting mechanical impact and isolating external high temperature; the shielding layer is a tinning braided shielding layer 3, and the outer protective layer is a 150 ℃ irradiation crosslinking polyolefin outer protective layer 4. In the use process, the soft structure conductor 1 is stranded by copper wires to transmit current, the conductor has stable structure and good flexibility, the product is convenient to be installed and used in a narrow space, and when the cable is heated at a high temperature (about 500-600 ℃), the main silicon rubber chain in the ceramic silicon rubber insulating layer 2 starts to be oxidized into silicon dioxide gradually, and calcium carbonate is further decomposed to generate calcium oxide and carbon dioxide along with the temperature. The generated calcium oxide and silicon dioxide further generate calcium silicate at high temperature to form a ceramic fire-resistant barrier layer with certain strength, the structure can protect a cable core from maintaining structural integrity in flame at high temperature of 650-1000 ℃ for a certain time (0.5-2 h), the cable core is prevented from being mechanically damaged or sprayed and shorted out by the outside, the outer protective layer 4 is a powerful protection of the cable to ensure the flame-retardant effect, and when external flame occurs, the 150 ℃ irradiation crosslinking polyolefin sheath material of the outer protective layer 4 can effectively prevent the flame from spreading through the cable wire to ensure that the whole battery assembly is not corroded by the flame or slowed down from being corroded by the flame.
The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
