Description

Technical Field

[0001] The present invention belongs to the technical field of high-voltage cables, and in particular relates to a high-performance high-voltage cable and a dynamic load management mechanism thereof. Background Art

[0002] High-voltage cables are constructed with thicker insulation and filler layers outside the conductor to isolate the voltage and provide protection. The most common cable maintenance issue is insulation damage. Because the insulation layer is typically composed of two layers, when the cable curves sharply, one end of the insulation and filler layers can become overstretched and lack support due to the sharp bend, while the other end can become overly squeezed and overloaded. This can lead to the insulation and filler layers lacking support for extended periods, causing them to deform and become susceptible to breakdown and damage from high voltage.

[0003] In everyday electricity use, dynamic load balancing uses an algorithm that takes into account the current status of the grid and each electricity user. It then distributes electricity accordingly to prevent grid overload. In practice, dynamic load balancing is needed when more vehicles and other consumers (heating, appliances) are charging and operating simultaneously. Its second function is a scheduling system that automatically manages the charging process of electric vehicles. It is optimized to use electricity optimally during off-peak hours. Only when the software includes both functions can it be called dynamic load management. Summary of the Invention

[0004] The purpose of the present invention is to provide a high-performance high-voltage cable and its dynamic load management mechanism, which has the advantage of reinforcing the bending angle of the cable, making the high-voltage cable more stable during use; and preventing the outer protective sheath from breaking due to tension when bending, which can effectively ensure the use effect of the cable.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: a high-performance high-voltage cable and its dynamic load management mechanism, including a management mechanism, the rear side of the management mechanism is connected to the cable body, the cable body includes an outer protective sleeve, an inner protective sleeve is provided inside the outer protective sleeve, an adapter component is provided between the outer protective sleeve and the inner protective sleeve, a wire core component is provided inside the inner protective sleeve, the adapter component includes a partition, the number of the partitions is five, and rubber blocks are equidistant and circumferentially distributed between two adjacent partitions, glue holes are formed between the two rubber blocks located at the top of the partition and inside the outer protective sleeve, connecting blocks are fixedly adhered between the two adjacent rubber blocks except for the glue holes, and steel sheets are fixedly installed on the surface of the rubber blocks.

[0006] With the above technical solution, for high-performance high-voltage cables and their dynamic load management mechanisms, the operator can bend the cable body according to the needs of the scene. An adapter component is provided inside the cable body to adapt the bending angle. After determining the bending angle, the prepared flow resin is poured into the adapter component. After waiting for a certain period of time, the resin will solidify, and the shape of the resin will not change under subsequent high temperature conditions. The solidified resin is conducive to reinforcing the angle of the cable, making the high-voltage cable more stable during use, and preventing the outer protective sheath from bending and breaking, which can effectively ensure the stability of the cable during use. At the same time, in the subsequent recycling of the cable, after stripping off the outer protective sheath of the cable body, the resin can be cleaned with the help of external tools, which will not have a major impact on the reuse of the cable, thus ensuring the use of the cable.

[0007] The present invention is further configured as follows: a filling layer is filled between the inner protective sleeve and the wire core assembly, a cavity for installing and accommodating the wire core assembly is opened inside the filling layer, and the materials of the outer protective layer and the inner protective layer are both polyvinyl chloride.

[0008] By adopting the above technical solution, the filling layer is used to support the inner protective sheath and the outer protective sheath, and is installed through the cavity to accommodate the core assembly, wherein the polyvinyl chloride will ensure that the outer protective sheath and the inner protective sheath have good flame retardant properties.

[0009] The present invention is further configured as follows: the wire core material includes an outer shielding layer, and an insulating layer is provided inside the outer shielding layer.

[0010] By adopting the above technical solution, the outer shielding layer and the insulating layer ensure the shielding and insulation effects of the two outer layers of the core component.

[0011] The present invention is further configured as follows: an inner shielding layer is provided inside the insulating layer, and a copper conductor is provided inside the inner shielding layer.

[0012] By adopting the above technical solution, the inner shielding layer further ensures the shielding performance of the copper conductor.

[0013] The present invention is further configured such that: the inner shielding layer and the outer shielding layer are both semiconductor shielding layers.

[0014] By adopting the above technical solution, the semiconductor shielding layer will be able to even out the electric field on the outer surface of the copper conductor, avoiding local discharge between the conductor and the insulation caused by the rough surface of the conductor and the air gap generated by the twisting of the copper conductor.

[0015] The present invention is further configured as follows: a plurality of adapter components are provided between the outer protective cover and the inner protective cover, and a filling block is provided between two adjacent adapter components.

[0016] Using the above technical solution, the adapter component is used to adapt to the angle bending of the cable during use, ensuring flexibility while increasing the toughness of the bending. The filling block can reduce the need for long cables to be frequently operated into the glue hole during use, and also fill the cost investment when the cable does not need to be bent. In addition, setting up multiple adapter components with a certain gap can meet the bending requirements of the cable.

[0017] The present invention is further configured as follows: both ends of the filling block are fixedly connected to the partition, and the filling block is made of soft and insulating rubber material.

[0018] By adopting the above technical solution, the filling block can ensure the stability and support effect between the two partitions, and the rubber material will ensure the softness of the filling block and provide insulation for the cable.

[0019] The present invention is further configured such that: the glue inlet hole is located between two adjacent partitions, and four glue inlet holes are provided in one adapter component.

[0020] With this technical solution, the prepared flowable resin is poured into the inlet. After a certain period of time, the resin solidifies and its shape remains unchanged under subsequent high temperature conditions. The partition is used to separate the resin for easy operation.

[0021] The present invention is further configured such that: the steel sheet is embedded in the surface of the rubber block and is located close to the inner protective sleeve.

[0022] By adopting the above technical solution, the steel sheet can be bent under the action of external force, and can also increase the firmness and toughness of the rubber block close to the inner protective cover.

[0023] The present invention is further configured as follows: a bottom plate is fixedly installed on the top of the management mechanism, a top cover is provided on the top of the bottom plate, a filling piece is fixedly adhered between the top cover and the bottom plate, and the filling piece is made of rubber.

[0024] By adopting the above technical solution, the top cover will provide the top of the management mechanism with protection against rain, hail and other bad weather conditions that may damage the top of the management mechanism. The rubber material will have the effect of sound insulation and buffering, so that the force caused by the impact is not enough to be transmitted to the bottom plate and the management mechanism. While reducing the impact of bad weather on the top of the management mechanism, it can also reduce the impact of shock on the internal electrical components of the management mechanism while reducing noise and sound insulation.

[0025] In summary, the present invention has the following beneficial effects:

[0026] For high-performance high-voltage cables and their dynamic load management mechanisms, operators can bend the cable body according to the needs of the scene. The internal steel sheet can be bent under the action of external force, and it can also increase the firmness and toughness of the rubber block close to the inner protective sheath. After determining the bending angle of the cable body, pour the prepared flow resin into the glue inlet. After waiting for a certain period of time, the resin will solidify and will not change its shape under subsequent high temperature conditions. At this time, the resin will fill the space between the outer protective sheath and the inner protective sheath. The solidified resin will help to strengthen the angle of the cable, making the high-voltage cable more stable during use.

[0027] For high-performance high-voltage cables and their dynamic load management mechanisms, this feature prevents the outer sheath from breaking due to tension during bending, effectively ensuring the cable's usability. Furthermore, during subsequent cable recycling, after peeling off the outer sheath, the resin can be cleaned with external tools without significantly impacting cable reuse, ensuring the cable's usability.

The solidified resin helps strengthen the cable angle, ensuring greater stability during use and preventing the outer protective sheath 201 from bending or breaking, effectively ensuring the cable's stability during use. Furthermore, during subsequent cable recycling, after removing the outer protective sheath 201 of the cable body 2, the resin can be removed using external tools without significantly impacting the cable's reuse, thus ensuring the cable's usability.
