特殊使用条件/Special service condition
在超过GB/T11022规定的正常环境条件下使用时，本公司和用户可就超出正常运行条件的特殊运行条件进行协商，并达成协议。为防止凝露现象，开关设
备设有加热器，当开关设备处于备用状态时即应投入使用。开关设备正常运行时也应注意投运加热器。
In case of application exceeding the specification of GB/T11022 ,the customer and the manufactuer shall negotiate and reach agreement . For preventing
condensation, the switchgear has heater which can be put into operation when the switchgear is at back up condition. The heater shall also be used in the
normal operation of the switchgear.
