High-voltage disconnectors are widely used in China’s power systems due to their convenient operation and strong practicality. However, during long-term operation, serious faults such as insulator fracture and failure to open/close still occur, significantly impacting the normal operation of power systems [1]. Based on this, this paper analyzes common faults of high-voltage disconnectors during operation and proposes corresponding solutions based on actual working conditions to improve managemen

High-voltage disconnectors require operating mechanisms with fast response and high output torque. Most current motor-driven mechanisms rely on a series of reduction components, yet motor-operated mechanism control systems effectively meet these requirements.1. Overview of the Motor-Operated Mechanism Control System for High-Voltage Disconnectors1.1 Basic ConceptThe motor-operated mechanism control system primarily refers to a system that employs a dual-loop PID control strategy to regulate moto

High-voltage disconnectors are critical protective devices in industrial electrical systems. Typically installed both indoors and outdoors at worksites, these disconnectors are prone to corrosion from multiple factors during long-term operation. This paper analyzes corrosion protection technologies for high-voltage disconnectors based on natural environmental conditions, internal structural design, and protective coating strategies, aiming to support the stable and reliable operation of relevant
