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

High-voltage disconnectors are extremely widely used, and therefore people pay great attention to potential problems that may arise with them. Among various faults, corrosion of high-voltage disconnectors is a major concern. In light of this situation, this article analyzes the composition of high-voltage disconnectors, types of corrosion, and faults caused by corrosion. It also investigates the causes of disconnector corrosion and studies theoretical foundations and practical techniques for cor

Traditional switches have become increasingly inadequate for the operational demands of modern traction power supply systems. The emergence of high-voltage disconnectors has effectively filled this gap. High-voltage disconnector systems optimize the structure of conventional switches, broaden their applicability, and place greater emphasis on fine details, thereby enhancing the safety and reliability of power systems during actual operation. Therefore, it is essential to analyze and study the ap

In the context of high-speed operation of power systems, the opening and closing mechanism of high-voltage disconnectors in substations faces challenges such as complex operational procedures, large workloads, and low operational efficiency. With the advancement of image recognition technologies and sensor innovations, modern intelligent substations now demand higher technical standards for monitoring the open/close positions of high-voltage disconnectors during infrastructure development.The in

The operational status of high-voltage disconnectors directly impacts the safety and stability of power grids. Currently, the operation and maintenance (O&M) of high-voltage disconnectors face numerous challenges—traditional O&M methods are inefficient, slow to respond, and struggle to accurately predict faults. Against this backdrop, developing a remote monitoring and fault early-warning system for high-voltage disconnectors is of great significance.1. Overall Design of the Remote Monit
