In power systems, high-voltage disconnectors in substations have suffered from aging infrastructure, severe corrosion, increasing defects, and insufficient current-carrying capacity of the main conductive circuit, significantly compromising power supply reliability. There is an urgent need to carry out technical retrofits on these long-in-service disconnectors. During such retrofits, to avoid interrupting customer power supply, the common practice is to place only the retrofit bay under maintena
