Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a high temperature resistant cable. Background Art

[0002] Power cables are cables used to transmit and distribute electrical energy. Power cables are commonly used in urban underground power grids, power station lead-out lines, internal power supply of industrial and mining enterprises, and underwater transmission lines across rivers and seas. In power lines, the proportion of cables is gradually increasing. Power cables are cable products used in the main lines of the power system to transmit and distribute high-power electrical energy, and also include various insulated power cables.

[0003] At present, the cables on the market are generally composed of a wire core and an insulating layer wrapped around the wire core, which results in poor heat dissipation of the cable. When the cable is used in a high current environment, the heat generated by the current flowing through the cable cannot be dissipated in time. Long-term use can easily cause the cable to spontaneously combust. For this reason, a high temperature resistant cable is proposed. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the heat dissipation effect of the cable is poor, resulting in the heat generated by the current flowing through the cable cannot be dissipated in time when the cable is used in a large current environment, and long-term use may easily cause the cable to spontaneously combust. The utility model provides a high-temperature resistant cable.

[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0006] A high temperature resistant cable, comprising:

[0007] A wire core, an insulating layer is provided on the outer side of the wire core, and a retaining frame is provided on the outer side of the insulating layer;

[0008] A heat sink, arranged outside the retaining frame, for dissipating heat from the retaining frame;

[0009] A support member, disposed inside the heat sink, for providing support to the heat sink;

[0010] The protective layer is arranged on the outside of the heat sink and is used to protect the cable.

[0011] Furthermore, a groove is provided inside the insulating layer, and the groove is multiple. A retaining hole is provided inside the insulating layer, and the retaining hole is multiple, and the retaining holes correspond to the insulating layer.

[0012] Furthermore, the heat sink comprises a contact plate, there are multiple contact plates, and the contact plates correspond to the grooves, a heat conducting plate is arranged on the outer side of each contact plate, and a heat dissipation pipe is arranged on the outer side of each heat conducting plate.

[0013] Furthermore, the support member includes a limiting layer, the limiting layer is arranged inside the heat pipe, a supporting layer is arranged inside the limiting layer, there are multiple supporting layers, a retaining layer is arranged inside the supporting layer, a fixed layer is arranged inside the retaining layer, and the heat conducting plates penetrate the fixed layer, the retaining layer and the limiting layer.

[0014] Furthermore, the protective layer includes a heat dissipation layer, which is arranged on the outside of the heat dissipation pipe, and the heat dissipation layer is provided with a heat dissipation groove on one side relative to the heat dissipation pipe, and the heat dissipation groove is multiple, and an insulation layer is provided on the outside of the heat dissipation layer, a reflective layer is provided on the outside of the insulation layer, and a wear-resistant layer is provided on the outside of the reflective layer.

[0015] Furthermore, the heat insulation layer is hollow.

[0016] The beneficial effects of the utility model are as follows:

[0017] The utility model realizes the cooperation of the insulating layer, groove, contact plate, heat conducting plate and heat dissipation pipe through the arrangement of the heat dissipation part and the insulating layer, so as to absorb and dissipate the heat generated by the wire core when it is used, thereby avoiding the poor heat dissipation effect of the cable, which leads to the situation that when the cable is used in a large current environment, the heat generated by the current flowing through the cable cannot be dissipated immediately, which easily causes the cable to spontaneously combust. The heat dissipation capacity of the cable is improved, the effective discharge of heat is ensured, the heat accumulation is reduced, the risk of spontaneous combustion is reduced, and the safety hazards such as short circuit and fire caused by overheating are reduced, thereby ensuring the safety of equipment and users.

[0018] Through the setting of the protective layer, the coordination of the wear-resistant layer, the reflective layer, the heat-insulating layer and the heat-dissipating layer is achieved, so as to block the heat absorbed by the outside and diffuse the temperature generated by the core outward, thereby reducing the heat entering the cable and effectively preventing the cable from overheating. The overall temperature of the cable is ensured to be stable during use. The wear-resistant layer effectively resists external physical wear and extends the service life of the cable.

[0030] like Figures 1 to 5As shown, a high temperature resistant cable comprises: a wire core 1, an insulating layer 101 is arranged on the outside of the wire core 1, and a retaining frame 102 is arranged on the outside of the insulating layer 101; a heat sink 2 is arranged on the outside of the retaining frame 102, and is used to dissipate heat from the retaining frame 102; a support member 3 is arranged inside the heat sink 2, and is used to provide support for the heat sink 2; a protective layer 4 is arranged on the outside of the heat sink 2, and is used to protect the cable. Specifically, when in use, the temperature of the wire core 1 is dissipated by the heat sink 2, and then the heat sink 2 is supported by the support member 3 to ensure stability during use, and finally the heat from the sun is reflected by the protective layer 4 to prevent the cable from heating up under the sun when in use.

[0031] like Figures 1 to 5 As shown, a groove 103 is opened inside the insulating layer 101, and there are multiple grooves 103. A retaining hole 104 is opened inside the insulating layer 101, and there are multiple retaining holes 104, and the retaining holes 104 correspond to the insulating layer 101. Specifically, the insulating layer 101 is made of high-temperature resistant insulating material to ensure the stability of the insulation of the wire core 1 when it is in use. When in use, the insulating layer 101 provides insulation for the wire core 1 to avoid short circuit caused by contact between the wire cores 1 during use. At the same time, the position of the wire core 1 is supported by the cooperation of the retaining frame 102 and the retaining hole 104 to avoid the wire cores 1 being squeezed against each other during use, resulting in damage and short circuit of the insulating layer 101.

[0032] like Figures 1 to 5 As shown, the heat sink 2 includes a contact plate 201, there are multiple contact plates 201, and the contact plates 201 correspond to the grooves 103. A heat conducting plate 202 is provided on the outside of the contact plates 201, and a heat dissipation pipe 203 is provided on the outside of the heat conducting plate 202. Specifically, the contact plate 201, the heat conducting plate 202 and the heat dissipation pipe 203 are all made of materials with good thermal conductivity, and the contact plate 201, the heat conducting plate 202 and the heat dissipation pipe 203 are all made of thermal conductive silicone material, so that they can bend and deform with the cable. When the cable is in use, the contact plate 201 absorbs the heat generated by the core 1, and the absorbed heat is transferred to the heat dissipation pipe 203 through the heat conducting plate 202, thereby dissipating the heat of the core 1 and ensuring stability during use.

[0033] like Figures 1 to 5As shown, the support member 3 includes a limiting layer 304, which is arranged inside the heat pipe 203, and a supporting layer 303 is arranged inside the limiting layer 304. There are multiple supporting layers 303, and a retaining layer 302 is arranged inside the supporting layer 303. A fixed layer 301 is arranged inside the retaining layer 302, and the heat conducting plate 202 passes through the fixed layer 301, the retaining layer 302 and the limiting layer 304. Specifically, the retaining layer 302 cooperates with the supporting layer 303 to provide support for the fixed layer 301 and the heat pipe 203 to ensure the stability of the shapes of the fixed layer 301 and the heat pipe 203 when in use. The limiting layer 304 connects the supporting layer 303 to prevent the supporting layer 303 from moving relative to the retaining layer 302 when in use, thereby ensuring the stability of the supporting layer 303 when supporting. A tensile rope is arranged inside the retaining layer 302, thereby increasing the tensile strength of the retaining layer 302 when in use, and avoiding damage to the wire core 1 under the action of tension.

[0034] like Figures 1 to 5 As shown, the protective layer 4 includes a heat dissipation layer 404, which is arranged on the outside of the heat dissipation pipe 203. The heat dissipation layer 404 has a heat dissipation groove 405 on one side relative to the heat dissipation pipe 203. There are multiple heat dissipation grooves 405. A heat insulation layer 403 is arranged on the outside of the heat dissipation layer 404. A reflective layer 402 is arranged on the outside of the heat insulation layer 403. A wear-resistant layer 401 is arranged on the outside of the reflective layer 402. Specifically, the heat dissipation layer 404 is made of a heat-conducting material, and a heat-conducting medium is filled in the heat dissipation groove 405. The contact area between the heat dissipation pipe 203 and the heat dissipation layer 404 is increased by the heat-conducting medium. The temperature of the heat dissipation pipe 203 is quickly absorbed to avoid temperature accumulation of the heat dissipation pipe 203 during use. At the same time, the temperature of the outside of the cable is blocked by the cooperation of the heat insulation layer 403 and the heat dissipation layer 404 to avoid the cable being heated up by the temperature of the outside. The reflective layer 402 is a metal reflective film, so when used outdoors, the reflective layer 402 reflects the sun's heat radiation. At the same time, the wear-resistant layer 401 protects the reflective layer 402 when the cable is laid to avoid damage to the reflective layer 402 during laying, thereby ensuring the stability of the cable during use.

[0035] like Figures 1 to 5 As shown, the heat insulating layer 403 is hollow. Specifically, the hollow heat insulating layer 403 is filled with a material that achieves unidirectional heat conduction through a multi-phase change process, thereby blocking the heat absorbed by the wear-resistant layer 401 and the reflective layer 402 while diffusing the heat generated by the wire core 1 outward, thereby preventing the heat absorbed from the outside from being conducted through the inside of the heat insulating layer 403.
