Description

Technical Field

[0001] This utility model relates to the field of busbar technology, specifically a rare earth high-speed rail aluminum alloy busbar for high and low voltage switchgear. Background Technology

[0002] High and low voltage switchgear is a core piece of equipment in power systems. The performance of its busbars directly affects power transmission efficiency, equipment operation stability, and safety. Traditional busbar structures typically use copper or aluminum busbars as conductors and fix the terminals with bolts or welding. However, traditional busbars usually require pre-drilling holes or slots in the copper or aluminum busbars and fixing them with bolts. This fixed design restricts wiring positions and makes it difficult to adjust flexibly according to actual installation needs. For example, when space inside the switchgear is limited or multiple branch wiring is required, the conductors with fixed holes may not meet the wiring requirements, leading to complicated installation and even requiring the customization of conductors with special sizes, increasing production costs and installation time.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 —4. A rare earth high-speed rail aluminum alloy busbar for high and low voltage switchgear, comprising a rare earth high-speed rail aluminum alloy busbar 100 and terminal pieces 200, wherein the rare earth high-speed rail aluminum alloy busbar 100 includes a vertical part 101 and a horizontal part 102 integrally formed with the vertical part 101, and the vertical part 101 and the horizontal part 102 form a T-shaped structure, and multiple sets of terminal pieces 200 are slidably connected on the rare earth high-speed rail aluminum alloy busbar 100.

[0024] Furthermore, the terminal block 200 includes an insulating sliding block 201, a rare earth high-speed rail aluminum alloy end post 202, an insulating spring 203, a rare earth high-speed rail aluminum alloy contact plate 204, a rare earth high-speed rail aluminum alloy terminal block 205, and a limiting member 206. In this embodiment, the insulating sliding block 201 is a ceramic sliding block made of ceramic material, which has the characteristics of high temperature resistance and good insulation. The insulating sliding block 201 is also provided with a T-shaped groove 207 in conjunction with the rare earth high-speed rail aluminum alloy busbar 100. The vertical part 101 and the horizontal part 102 are located in the T-shaped groove 207, so that the insulating sliding block 201 can move linearly on the rare earth high-speed rail aluminum alloy busbar 100. The sliding stability of the insulating sliding block 201 can be ensured by the cooperation between the T-shaped groove 207 and the T-shaped structure of the rare earth high-speed rail aluminum alloy busbar 100.

[0025] In addition, an elastic groove 208 is provided on the insulating sliding block 201, and the rare earth high-speed rail aluminum alloy end post 202 is slidably connected to the insulating sliding block 201. The inner end of the rare earth high-speed rail aluminum alloy end post 202 is located in the elastic groove 208 and is fixedly connected to the rare earth high-speed rail aluminum alloy contact plate 204. An insulating spring 203 is also provided in the elastic groove 208. One end of the insulating spring 203 abuts against the rare earth high-speed rail aluminum alloy contact plate 204, and the other end abuts against the inner wall of the elastic groove 208. When the insulating sliding block 201 is slidably installed on the rare earth high-speed rail aluminum alloy busbar 100, under the elastic force of the insulating spring 203, the rare earth high-speed rail aluminum alloy contact plate 204 can be tightly abutted against the vertical part 101.

[0026] A rare earth high-speed rail aluminum alloy terminal block 205 is also fixedly connected to the rare earth high-speed rail aluminum alloy end post 202 near its outer end. The rare earth high-speed rail aluminum alloy end post 202 is provided with a threaded part 209 near its outer end. The threaded part 209 is fitted with a nut 210. The movement of the rare earth high-speed rail aluminum alloy contact plate 204 can be limited by the rare earth high-speed rail aluminum alloy terminal block 205, and the conductive area of ​​the wiring can also be increased. When wiring, the hole on the wire terminal can be inserted into the threaded part 209, and then the nut 210 is threaded onto the threaded part 209. The nut 210 presses the wire terminal tightly down onto the rare earth high-speed rail aluminum alloy terminal block 205, thus realizing the wire connection.

[0027] The aforementioned grounding busbar, terminal post, contact plate, and junction box are all made of rare earth high-speed iron aluminum alloy, which has high conductivity, high strength, and corrosion resistance, while reducing cost and weight, and solving the problems of insufficient conductivity of pure aluminum and high cost of copper.

[0028] To further optimize the process and ensure the insulating sliding block 201 remains stable after it has moved into position, a limiting component 206 is provided on the insulating sliding block 201. The limiting component 206 includes a knob 211, a screw 212, and an insulating base 213. Specifically, the insulating sliding block 201 has a storage groove, and a screw 212 is threadedly connected to the insulating sliding block 201. The bottom end of the screw 212 is located in the storage groove and is fixedly connected to the insulating base 213. The insulating base 213 abuts against the transverse portion 102 of the rare earth high-speed rail aluminum alloy busbar 100, and a knob 211 is fixedly connected to the top end of the screw 212. The insulating base 213 is made of rubber. The insulating sliding block 201 is limited by the friction between the insulating base 213 and the rare earth high-speed rail aluminum alloy busbar 100.

[0029] Finally, to improve structural stability, the rare earth high-speed rail aluminum alloy end post 202, the rare earth high-speed rail aluminum alloy contact plate 204, and the rare earth high-speed rail aluminum alloy terminal block 205 are integrated into one structure.
