Description

Technical Field

[0001] The present invention relates to the technical field of electric power equipment, and in particular to a pre-assembled high-voltage lead wire assembly for a 10kV distribution transformer rack. Background Art

[0002] The high-voltage lead-in assembly on the 10kV distribution transformer rack is a prefabricated connection system designed for 10 kV distribution transformers. The main function of the high-voltage lead-in assembly is to provide a fast and reliable connection solution for connecting the distribution transformer to the high-voltage transmission line. By using prefabricated connectors, the need for on-site welding and manual connection can be reduced, which not only speeds up the installation, but also reduces the potential safety risks caused by human errors. In addition, prefabricated connectors usually have high pressure resistance and waterproof performance, ensuring the long-term stability and reliability of the connection.

[0003] 10kV distribution transformer racks are mostly installed on double poles composed of two adjacent columns. After installing the transformer, the lead wire assembly is installed to fix the high-voltage line. The traditional assembly is that multiple racks are fixed on the double poles respectively, and then the high-voltage line is connected to the fuses, lightning arresters, porcelain crossarms and other power devices on the racks in turn. When installing the racks, they are installed separately and the devices on the racks are installed in turn, which is very time-consuming.
