摘　　要：本文通过研究某一原有1250A气体绝缘开关柜的母线连接器组件结构特点和绝缘性能,重新设计了一种绝缘硅橡胶结构,使得该母线连接器的绝缘性能提高到40.5kV额定电压等级,并通过了绝缘试验验证;然后优化设计了母线连接器的搭接端子,使其额定电流等级达到1250A,并通过温升验证。优化设计的绝缘硅橡胶和母线连接器,组成了40.5kV-1250A母线连接器组件。该组件成功应用于40.5kV-1250A的气体绝缘开关柜中,具有绝缘安全可靠、空间紧凑、成本低的优点。Based on studying an existing 1250A busbar socket assembly design feature and verified its dielectric performance,a new insulated silicon was designed to upgrade the busbar socket rated voltage to 40.5kV and passed dielectric test.And then redesigned a new busbar socket contact terminal to make sure its rated current up to 1250A and passed temperature-rise test.The new design insulated silicon and the new design busbar socket are installed together to compose as a 40.5kV-1250A busbar socket assembly.This busbar socket assembly has been applied on 40.5kV-1250A gas insulated switchgears.Its main features are safe and reliable,compact and low cost.
