The working environment of medium and low voltage uninterrupted power supply in the distribution network is complex,posing a serious challenge to the safety of operators.Therefore,key technology research on composite insulation partitions is proposed to improve operational safety.Based on the characteristics of uninterrupted operation of medium and low voltage in the distribution network,a composite insulation partition was designed,which is composed of multiple layers of insulation materials to improve insulation performance and electric field shielding ability.And special installation tools are used to ensure the insulation and stability during the installation process of the insulation partition,while precisely controlling the insulation distance between the insulation partition and the live and grounded bodies.The experimental results show that the monitoring data of leakage current and electric field strength of the composite insulation partition are far below the safety limit,indicating that it has good insulation performance and electric field shielding ability,providing key technical support for medium and low voltage uninterrupted operation in the distribution network,effectively ensuring the safety of operators during uninterrupted operation.
