Abstract: The gas-insulated busbar is a power transmission device with a large transmission capacity and high reliability. The coil spring contact is a vital component of the busbar module.This research designed a new type of spring contact based on the voltage level and insulation level.It improved the structure of the conductive rod and the coil spring, checked the current capacity of the coil spring, and used finite element software to optimize the contact structure.This paper ensures the rationality of the new type of spring contact design by calculating the contact pressure of the contacts and checking the thermal stability.
Key words: gas insulated busbar; new type of spring contact; coil spring; thermal stability
