Background technique

Tubular busbar is one of the key equipment in the power transmission and transformation system, which plays a vital role in the safe and reliable operation of the power transmission and transformation system and power equipment. It is mainly used in power grid transmission wires and substations in my country's electric power construction projects Conductor connections between transformers, jumper wires in transmission lines, connecting conductors in power equipment, and overcurrent conductors in high-current DC ice-melting devices.

At the same time, when the tubular busbar is connected to electrical equipment such as gas cabinets, excessive partial discharge is prone to occur, which greatly affects the working safety of various electrical equipment. In the past, the connection was mostly carried out by wrapping Shielding requires too many auxiliary materials and needs to be produced on site. Although it can reduce partial discharge (partial discharge) to a certain extent, the sealing is not good, the effect of reducing partial discharge is not particularly significant, and the service life Shorter, there are greater safety hazards, and at the same time, the installation method is cumbersome, and it is difficult to wrap, which is not conducive to on-site construction and later maintenance.
