某型号运载火箭测量系统测试电源分析

运载火箭供配电系统是完成系统测试的重要组成部分,其电路设计原则要求箭地供配电分开,系统间供配电不得相互干扰。某型号运载火箭测量系统地面供配电设备改造后,经多发任务测试发现,在系统转电过程中地面测试电源电流出现异常跳变。从系统供配电原理和电路设计的原则出发,分析了测试电源电流跳变的原因,指出了供配电电路设计存在的缺陷并提出了改进设计的建议。

Test power source analysis of measuring system on a certain type of launch vehicle

The power supply system on launch vehicle is an important part used to accomplish system testing.The design principle of its circuit requires the power supply of the launch vehicle separating from ground equipment,and no interference is accepted between different systems.Through lots of testing in many missions,the current of ground test power source showed abnormal abrupt change during power switching after renovations of the ground power supply equipment of the measuring system on a certain type of launch vehicle.Based on power supply theory and circuit design principle,the causes of the current abrupt change of the test power source were analyzed,the deficiencies of the power supply circuit design were pointed out,and the advice on design innovation was proposed.
