Description

Technical Field

[0001] The present invention relates to the technical field of electrical connection, and more particularly to an insulated multi-layer copper busbar. Background Art

[0002] Copper busbar is an electrical conductor widely used in power equipment, mainly made of copper; insulated multi-layer copper busbar is composed of multiple layers of copper busbars stacked together, and each layer of copper busbar is usually separated by insulating material. By stacking copper busbars to increase the total conductive cross-section, it helps to reduce resistance and disperse current, thereby improving the overall current carrying capacity and stability of the system, while also improving insulation safety, helping to prevent electrical failures and improve equipment reliability.

[0003] In the prior art, the copper busbar is generally sheathed with a heat shrink tube, which is then tightly sheathed with the copper busbar after being heat-shrunk with an electric hot air gun, an oven or a baking oven, and then installed on the machine one by one, with the copper busbars fitting together alternately and arranged in layers. When installing the copper busbar, the multi-layer copper busbar is generally fixed to the power equipment or the rack by brackets and clamps, but when vibration or impact occurs, the copper busbar may become loose, and the loose copper busbar may cause poor electrical contact, thereby increasing the contact resistance. The increase in contact resistance generates more heat when the current passes through the copper busbar, causing local overheating and thus affecting the stability and safety of the system. Therefore, the copper busbar needs to be checked regularly and the loose copper busbar needs to be re-fixed.

[0004] However, the insulated multi-layer copper busbar is composed of multiple layers of copper busbars stacked on top of each other. When re-fixing the insulated multi-layer copper busbar, each layer of the copper busbar needs to be fixed separately. Therefore, when re-fixing the insulated multi-layer copper busbar, a lot of time is required, which increases the workload of the staff and the maintenance cost of the equipment.

The connecting rope 523 is continuously pulled to move the first slot 522 of the connecting rope 523, thereby driving the sliding block 517 and the connecting block 521 on the side of each copper busbar 1 to move. When the sliding block 517 moves close to the mounting bracket 2, the sliding block 517 gradually squeezes the spring bellows 514, thereby squeezing the spring bellows 514. 14. Part of the gas in the telescopic cylinder 511 and the suction cup 512 is discharged from the one-way valve 513, and the gas is discharged from the one-way valve 513, so as to fix the mounting bracket 2 and the copper busbar 1, and avoid the copper busbar 1 from loosening and causing poor electrical contact, avoid increasing contact resistance, and avoid generating more heat when the current passes through the copper busbar 1, which is beneficial to the stability and safety of the system. When the copper busbar 1 is regularly inspected, multiple copper busbars 1 can be fixed at one time, thereby reducing the workload of the staff and the maintenance cost of the equipment.

The cleaning piece 531 moves to clean the dust on the surface of the copper bus 1 to prevent the dust from causing poor electrical contact at the end of the copper bus 1, thereby increasing the contact resistance and affecting the electrical performance of the system. When the scraper piece 532 moves to a position close to the mounting bracket 2, the dust cleaned by the cleaning piece 531 is removed from the surface of the copper bus 1 to prevent the dust from accumulating at the end of the copper bus 1 and affecting the stability of the copper bus 1.

When the connecting plate 5311 moves close to the mounting bracket 2, the second magnet 5324 and the first magnet 5322 attract each other, so that the scraper 5321 slides in the second sliding groove 5312. The scraper 5321 slides to scrape the dust cleaned by the bristles 5313 from the surface of the copper busbar 1, avoiding dust accumulation at the end of the copper busbar 1, resulting in poor electrical contact at the end of the copper busbar 1, avoiding increased contact resistance, affecting the electrical performance of the system, and facilitating the stability and safety of the system.
