摘要： 针对SF6气体绝缘环网柜存在的温室效应问题，开发出一种12kV环保气体绝缘环网柜。该环网柜以N2绝缘作为绝缘介质，通过上隔离五工位开关（三工位隔离开关和真空断路器一体化）、母线及电缆出线部分结构设计措施，解决了环网柜尺寸设计、绝缘设计关键问题，且通过了型式试验验证。
Abstract: In view of the greenhouse effect problem of SF6 gas-insulated ring main unit, a 12kV environment-protection gasinsulated ring main unit is developed. The ring main unit takes nitrogen insulation as the insulation medium. Through the structural design measures of upper isolation five position switch (integration of three position disconnector and the vacuum circuit breaker), bus and cable outgoing line, the key problems of size design and insulation design of ring main unit are solved, and have passed the type test verification.
