正常工作條件 Normal working conditions
◇ 電容器從電源切除后一定要保證電容器剩余電壓降至10% 額定電壓才允許再次投入，通常情況這個時間約需200s，所以控制器要選用帶有切除后再投入有再投鎖定時間功能的控制器。如果采用一般控制器，要另裝快速放電設(shè)施。對于采用等電位投切開關(guān)的可以不受此限。
◇ 海拔高度不超過2000m。

◇ 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.
