GW5-40.5户外高压隔离开关参数
概述:
GW5-40.5高压隔离开关是发电厂和变电站电气系统中重要的开关电器,需与高压断路器配套使用,其主要功能是:保证高压电器及装置在检修工作时的安全,起隔离电压的作用,不能用与切断、投入负荷电流和开断短路电流,仅可用于不产生强大电弧的某些切换操作,即是说它不具有灭弧功能;按安装地点不同分为,屋内式和屋外式,按绝缘支柱数目分为,单柱式,双柱式和三柱式,各电压等级都有可选设备。
使用环境:
1、海拔高度不超过2500米;
2、周围空气温度:上限+40℃,下限一般地区-30℃高寒地区-40℃;
3、风压不超过700Pa(相当于风速34m/s);
4、***烈度不超过8度;
5、适用于当量附盐密度不大于0.35mg/cm2污秽等级;
6、无频繁剧烈震动场所;
7、普通型安装场所应无严重影响隔离开关绝缘和导电能力的气体、蒸气、化学性沉积、盐雾、灰尘及其它***性、侵蚀性物质。防污型适用于重污秽地区,但不应有引起火灾及***物质。
