摘　　要：针对交流电源短暂电压跌落引起市电直供的大功率脉冲测量雷达伺服、发射机和水冷系统保护停机的问题,叙述了雷达系统组成及对应功率容量。分析了采用双变换不间断电源和市电同时向伺服系统、发射机及水冷系统的低压控制电路和大功率部件区别供电的可行性。提出了改进分机低压控制线路和可编程逻辑控制器控保逻辑的建议,提高了雷达系统抵抗电压短暂跌落的能力。According to the protection shutdown problem of high power pulse instrumentation radar caused by alarm of servo, trans- mitter and forcing water cooling system due to alternation current （ AC ） power supply voltage sag, the simple description of pulse radar system composition and the corresponding power capacity is presented. A detailed analysis of feasibility to pnuer the servo, transmitter and water cooling system by AC power and uninterrupted power supply （ UPS ） , simultaneously power are specially em- phasized. The improvement suggestions of low voltage control circuit and the corresponding control and protection logic of program- mable logic controller are put forward to improve the ability of radar system against voltage transient sag.
