正常工作条件 Normal working conditions

◇ 电容器从电源切除后一定要保证电容器剩余电压降至10% 额定电压才允许再次投入，通常情况这个时间约需200s，所以控制器要选用带有切除后再投入有再投锁定时间功能的控制器。如果采用一般控制器，要另装快速放电设施。对于采用等电位投切开关的可以不受此限。

◇ After the capacitor is removed from the power supply, it must be ensured that the remaining voltage of the capacitor drops to 10% of the rated voltage before it is allowed to be put in again. If the general controller is used, a separate fast discharge facility should be installed. For the use of equipotential throwing switch can not be subject to this limit.

◇ The altitude should not exceed 2000m.
