    Abstract: As the core power transmission component in traditional gas-insulated switchgear, insulating bushings face challenges such as difficult fault repair and lack of intelligent monitoring. A split-type digital insulating bushing has been developed. At the structural design level, it adopts a split-type structure with dual sealing and integrates electronic instrument transformers. At the performance research level, it leverages finite element analysis software for mechanical strength calculations and electric field simulation optimization. Concurrently, type tests including strength and insulation verification ensure stability under complex operating conditions. Field applications demonstrate that this bushing effectively reduces operational and maintenance costs for gas-insulated switchgear, resolves prolonged restoration times for high-frequency cable faults, and enhances both operational reliability and economic efficiency of power systems.
    Key words: gas-insulated switchgear; insulating bushing; split-type structure; digital monitoring; electrostatic field analysis
