Abstract

In modern power system, SF6 circuit breaker undertakes the important tasks of short circuit protection, switching control, and power distribution, which is an important factor to maintain the safe and stable operation of the system. The ablation caused by arc will shorten the electrical life and breaking performance of the contact system. Therefore, it is necessary to study the electrode ablation characteristics in SF6 gas arc and explore the influence of different factors on the electrode ablation. In this paper, based on the new in-situ optical diagnosis platform, the ablation of copper–tungsten contacts is studied experimentally, which provides theoretical support and basic parameters for the design and optimization of SF6 circuit breaker contact system.
