使用环境限制：
安装在离变电所较近处，在变电所出线开关零时限速断保护范围内的柱上真空开关线路柱上真空开关，应当选用负荷开关，不4 应选用切断故障短路电流的断路器，否则，将会发生无选择性的越级跳闸或乱跳闸事故。
大部分柱上真空开关应该选用负荷开关吗有人以为制造10kv柱上真空断路器与制造10kv柱上负荷开关的成本相差不是太多，还是使用真空断路器安全。这是一种认识上的误区，根本还没有认识到到，如果滥用断路器引起误跳闸，将大|大增加供电部门处理误跳闸事故的工作量，不但没有好处，反而降低了供电可靠性
户外布置还需要注意一下问题，周围空气温度限高温度：+40℃;极低温度：-15℃：限大日温差：25k 2.3 海拔限度 小于1000m ；周围环境湿度：月平均相对湿度不大于90%;日平均相对湿度不大于95% 在有的地震烈度地区：不能超过8度2。 限大风速 35m/s 2.8环境污秽等级：ⅱ级(除特别说明外)。
