In order to clarify the efficient measures to optimize the insulation performance of the high voltage switchgear, the article takes the project of "Shanghai North Yunlifang Apartment 10kV ordinary residential red line access project (Shouyang 88 Lane Station), North Jing and City North high-tech Shouyang Road 88 Lane) as an example, through the analysis of the insulation fault types and the insulation performance optimization design of the high voltage switchgear. The necessity of optimizing the insulation performance of 10kV switchgear in this project is proved, and it is clear that the safety distance design of secondary components and insulation distance design directly affect the insulation performance of the switchgear, and designers need to pay attention to it. At the same time, it can be concluded that the stable operation of high voltage switchgear is closely related to the performance of the power system, so it is necessary to optimize the insulation performance of high voltage switchgear and take targeted measures to reduce the incidence of insulation failures and ensure the safety of operators.
