Description

Technical Field

[0001] This utility model relates to the field of high-voltage cable connection technology, and in particular to a high-voltage connector. Background Technology

[0002] In power transmission and distribution systems, power cables are a particularly critical transmission medium; among them, high-voltage cables are a type of power cable with unique performance characteristics and application scenarios. High-voltage cables are specifically designed to transmit voltages above 1KV and are mainly used in the main power transmission lines. They bear the important task of efficiently and stably transmitting electrical energy from power plants or large substations to various areas, and are a key link in ensuring the normal operation of the entire power system and the reliable supply of power. However, the laying of high-voltage cables often requires adjustments based on actual conditions, which inevitably involves bending along the way. Furthermore, when connecting high-voltage cables to high-voltage equipment, bending operations are often necessary according to the interface location and installation requirements of the equipment to ensure the safety and reliability of the connection.

[0003] However, bending high-voltage cables is not arbitrary and requires consideration of numerous technical factors and limitations, the most critical of which is the bending radius. High-voltage cables typically consist of multiple conductors, insulation layers, shielding layers, and sheathing layers. If the bending radius is too small, the conductors will be subjected to excessive stretching and compression, leading to insulation damage and shielding failure. This affects cable performance, reduces insulation resistance, increases the risk of leakage, and may even cause serious accidents such as short circuits, threatening the safe and stable operation of the power system. According to industry standards and practical engineering experience, the minimum bending radius of a cable is typically 15-20 times its diameter. However, due to the large diameter of high-voltage cables, a significant amount of space is required when bending them to meet the minimum bending radius requirement. For example, a high-voltage cable with a diameter of 20 centimeters has a minimum bending radius of 3 meters when calculated by multiplying by 15. This means that at least 3 meters of space needs to be reserved when bending the cable. This poses a great challenge in some spaces with limited space, such as narrow tunnels or inside buildings. It not only increases the difficulty and cost of cable laying or connecting to high-voltage equipment, but may also affect the progress and quality of the entire project.

[0021] The present invention will be further described in detail below with reference to specific embodiments:

[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] A high-voltage connector, such as Figure 1As shown, the device includes an insulator housing 1 with a through hole 3 on its side for a high-voltage cable 2 to pass through. Inside the insulator housing 1 is a pin assembly 4, with its central axis parallel to the central axis of the insulator housing 1. One end of the pin assembly 4 is connected to a conductor in the high-voltage cable 2, and the other end is fixedly connected to a pin assembly 5. The other end of the pin assembly 5 extends to the outside of the insulator housing 1 for insertion into high-voltage equipment, thus achieving a safe and reliable connection between the high-voltage cable and the high-voltage equipment. In traditional structures, the cable is directly bent at 90° and fixed with a flange, which occupies a large space. However, the high-voltage connector provided in this application has the central axis of the pin assembly 4 perpendicular to the central axis of the high-voltage cable 2. This 90° distribution greatly reduces the space occupied when bending the high-voltage cable. This high-voltage connector can easily achieve bending connections of the high-voltage cable 2 in spaces with limited space, such as narrow tunnels or inside buildings, improving space utilization.

[0024] To effectively prevent safety accidents such as leakage and short circuits, and to ensure the safe and stable operation of the power system, high-voltage connectors are also equipped with cable sheaths 8; such as Figure 2 As shown, the cable sheath 8 is tightly fitted onto the high-voltage cable 2; and one end of the cable sheath 8 passes through the through hole 3 together with the high-voltage cable 2. To ensure that the cable sheath 8 can better fit the high-voltage cable 2 and provide better protection, the cable sheath 8 is preferably made of an elastic material; furthermore, using an elastic material to make the cable sheath 8 can also better adapt to the usage requirements of high-voltage cables 2 of different specifications and shapes.

[0025] like Figure 3 As shown, the insulator housing 1 also has a chamber 6 inside for accommodating the high-voltage cable 2; a pin assembly is disposed between the insulator housing 1 and the chamber 6; the high-voltage cable 2 passes through the through hole 3 and extends into the chamber 6, and the wires in the high-voltage cable 2 are fixedly connected to the pin assembly after passing through the chamber 6. Meanwhile, to further improve the insulation performance of the high-voltage connector, insulating adhesive 7 is filled between the chamber 6 and the insulator housing 1; by filling with insulating adhesive 7, safety hazards such as leakage can be effectively prevented, ensuring the safe use of the high-voltage connector.

[0026] Furthermore, to facilitate easier and faster connection and subsequent maintenance between the high-voltage connector and the high-voltage cable 2, the insulator housing 1 adopts a split design. The insulator housing 1 includes an insulator housing side plate 11, an insulator housing bottom plate 12, and an insulator housing cover plate 13. The insulator housing cover plate 13 is composed of a thermally conductive insulating medium layer, which ensures good insulation performance and facilitates heat dissipation. The through hole 3 is provided on the insulator housing side plate 11, while the pin assembly is located between the insulator housing cover plate 13 and the chamber 6.

[0027] To meet different usage requirements, the pin assembly includes at least two pins; the pin assembly 5 includes the same number of pins as the pins; each pin is independently fixedly connected to one of the pins in the pin assembly 5. This design improves the stability and reliability of the connection and helps to ensure stable power transmission between the high-voltage cable 2 and the high-voltage equipment.

They should not be construed as limiting the scope of protection of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
