Description

Technical Field

[0001] This utility model belongs to the field of center conductors, specifically relating to highly conductive center conductors. Background Technology

[0002] Three-post insulators are crucial electrical components in gas-insulated metal-enclosed transmission lines (GILs). Their primary function is to support the internal current-carrying conductors while simultaneously insulating and isolating the high-voltage conductors from the low-voltage casing. The performance of the three-post insulator directly impacts the long-term, stable, and reliable operation of the GIL.

[0003] Regardless of the structural shape of the insulator, the supporting insulator and the conductor must achieve a fixed connection in both the axial and circumferential directions.

[0004] In the prior art, when a high conductivity center conductor is energized, the center conductor itself generates a large amount of heat. However, the heat dissipation effect of the high conductivity center conductor in the prior art is poor, which makes the high conductivity center conductor prone to high temperature, thereby reducing the conductivity performance. Utility Model Content

[0005] The purpose of this invention is to provide a high-conductivity central conductor, which aims to solve the problem that the heat dissipation effect of the high-conductivity central conductor in the prior art is poor, which leads to the high-temperature occurrence of the high-conductivity central conductor and thus a significant reduction in conductivity.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] Highly conductive center conductor, including:

[0008] guide;

[0009] The arc-shaped connecting groove is provided in three places. All three arc-shaped connecting grooves are provided on the circumferential surface of the guide plate and are evenly distributed.

[0010] The thermally conductive pins are provided in three parts, and each thermally conductive pin is located in each arc-shaped connecting groove;

[0012] The auxiliary components are provided in three groups, with each group of auxiliary components located on each heat-conducting pin.

[0013] As a preferred embodiment of this utility model, each set of auxiliary components includes a heat dissipation groove B and an arc-shaped heat-conducting sheet. Two arc-shaped heat-conducting sheets are provided, and both arc-shaped heat-conducting sheets are fixedly connected to the heat-conducting pin. The two arc-shaped heat-conducting sheets are arranged symmetrically. Two heat dissipation grooves B are provided, and each heat dissipation groove B is formed on each arc-shaped heat-conducting sheet.

[0014] As a preferred embodiment of this utility model, the guide plate is provided with a plurality of heat dissipation grooves A, and the plurality of heat dissipation grooves A are evenly distributed.

[0015] As a preferred embodiment of this utility model, the three arc-shaped connecting grooves are all formed on the circumferential surface of the guide plate, each heat-conducting pin is fixedly connected to each arc-shaped connecting groove, and each hollow inner ring is formed on each heat-conducting pin.

[0016] As a preferred embodiment of this utility model, the arc of each of the arc-shaped heat-conducting sheets is 14.5 degrees.

[0017] As a preferred embodiment of this utility model, the guide plate is made of copper and has a silver plating layer on its surface.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. In this solution, the heat dissipation effect can be improved by setting the heat conduction pins, so that the heat generated by the conductive plate when it is powered on can be transferred out through the heat conduction pins, thereby reducing the temperature of the conductive plate itself. By setting the hollow inner ring, gas can pass through the hollow inner ring. After passing through the hollow inner ring, the gas will carry away the heat on the heat conduction pins, thereby achieving cooling.

[0020] 2. In this solution, the arc-shaped heat-conducting sheet can conduct heat on the heat-conducting pin, allowing the heat-conducting pin and the arc-shaped heat-conducting sheet to dissipate heat simultaneously, thereby improving the heat dissipation effect. The heat dissipation groove B can increase the contact area between the gas and the arc-shaped heat-conducting sheet, thereby improving the heat dissipation effect. The combination of heat dissipation groove A and heat dissipation groove B can improve heat dissipation, thereby increasing the contact area between the heat-conducting sheet and the gas, and thus reducing the temperature of the heat-conducting sheet itself.

[0029] The highly conductive center conductor consists of a conductive plate 1, an arc-shaped connecting groove 3, a heat-conducting pin 4, a hollow inner ring 7, and auxiliary components. There are three arc-shaped connecting grooves 3, all of which are located on the circumferential surface of the conductive plate 1 and are evenly distributed. There are three heat-conducting pins 4, each located within each arc-shaped connecting groove 3. There are three hollow inner rings 7, each located on each heat-conducting pin 4.

[0030] In a specific embodiment of this utility model, the heat dissipation effect can be improved by setting the heat-conducting pin 4, so that the heat generated by the conductive plate 1 when it is powered on can be transferred out through the heat-conducting pin 4, thereby reducing the temperature of the conductive plate 1 itself. By setting the hollow inner ring 7, gas can pass through the hollow inner ring 7. After passing through the hollow inner ring 7, the gas will carry away the temperature on the heat-conducting pin 4, thereby achieving cooling.

[0031] Specifically, there are three sets of auxiliary components. Each set of auxiliary components is located on each heat-conducting pin 4. Each set of auxiliary components includes a heat sink B5 and an arc-shaped heat-conducting plate 6. There are two arc-shaped heat-conducting plates 6, which are fixedly connected to the heat-conducting pin 4 and are symmetrically arranged. There are two heat sinks B5, and each heat sink B5 is opened on each arc-shaped heat-conducting plate 6.

[0032] In a specific embodiment of this utility model, the arc-shaped heat-conducting sheet 6 can conduct heat on the heat-conducting pin 4, so that the heat-conducting pin 4 and the arc-shaped heat-conducting sheet 6 can dissipate heat simultaneously, thereby improving the heat dissipation effect. The heat dissipation groove B5 can increase the contact area between the gas and the arc-shaped heat-conducting sheet 6, thereby improving the heat dissipation effect.

[0033] Specifically, the guide plate 1 has multiple heat dissipation slots A2, which are evenly distributed.

[0034] In a specific embodiment of this utility model, the heat dissipation can be improved by setting heat dissipation groove A2 and heat dissipation groove B5, thereby increasing the contact area between the guide plate 1 and the gas, and thus reducing the temperature of the guide plate 1 itself.

[0035] Specifically, three arc-shaped connecting grooves 3 are all opened on the circumferential surface of the guide plate 1, each heat-conducting pin 4 is fixedly connected in each arc-shaped connecting groove 3, and each hollow inner ring 7 is opened on each heat-conducting pin 4.

[0036] Specifically, the curvature of each arc-shaped heat-conducting plate 6 is 14.5 degrees.

[0037] Specifically, the guide sheet 1 is made of copper and has a silver plating layer on its surface.

[0038] In a specific embodiment of this utility model, copper is selected as the material for the conductive sheet 1, which can improve conductivity.

[0039] The working principle or process of the high conductivity center conductor provided by this utility model is as follows: The heat dissipation effect can be improved by setting the heat-conducting pin 4, so that the heat generated by the conductor 1 when energized can be transferred out through the heat-conducting pin 4, thereby reducing the temperature of the conductor 1 itself. The hollow inner ring 7 allows gas to pass through the hollow inner ring 7. After passing through the hollow inner ring 7, the gas will carry away the temperature on the heat-conducting pin 4, thereby achieving cooling. The arc-shaped heat-conducting plate 6 can conduct the heat on the heat-conducting pin 4, so that the heat-conducting pin 4 and the arc-shaped heat-conducting plate 6 can dissipate heat simultaneously, thereby improving the heat dissipation effect. The heat dissipation groove B5 can increase the contact area between the gas and the arc-shaped heat-conducting plate 6, thereby improving the heat dissipation effect. The heat dissipation grooves A2 and B5 can improve heat dissipation, thereby increasing the contact area between the conductor 1 and the gas, thereby reducing the temperature of the conductor 1 itself.
