摘要
根据深圳地铁工程维护车技术要求,从导流截面积、簧片的接触压力、主回路温升以及限位弹簧参数等方面对隔离接地开关进行设计计算,确保设计满足标准和用户要求。
According to the technical requirements of Shenzhen subway maintenance locomotive,diversion cross-sectional area,contact pressure on the spring contact,temperature rise in main circuit and parameter of limited location spring are calculated. This product meets design standards and user＇s requirements.
