摘要:创建高铁供电实验系统,是为了让与轨道交通电气化有关的院校及单位全面的了解高速铁路的供电系统。而在高速铁路供电实验系统中故障模拟部分又是它的重要组成部分,在高速铁路供电系统中会出现各种各样的故障,而这些故障在故障模拟部分能够直观的模拟,从而使大家对在高铁供电系统出现的一些故障有了一些了解,对于一些故障我们如果用实物进行模拟的话不仅会非常的危险,而且还会浪费很多不必要的资源。高铁供电实验系统故障部分对高铁供电系统中故障的模拟,是通过模拟故障最终输出的信号来实现对故障的模拟,所以对于高铁供电实验系统故障部分来说,既能够模拟供电系统的故障,而且有安适还节约资源。34797

High-speed rail power supply part of the design of fault simulation experiment
Summary:High-speed rail power supply test system allows rail electrification relevant institutions and units comprehensive understanding of high-speed railway power supply system,.Fault simulation part is an important part of the high-speed rail power supply test systems, fault simulation portion can be intuitive simulation of high-speed rail power supply system ,produced some of the failures that can make you some faults on high-speed rail power supply system will be understood that.Because some of the fault simulation, then if something is not only dangerous, but also and especially the waste of resources. High-speed rail power supply test system failure part simulation of high-speed rail power supply system failure is a signal by simulating failure of the final output to achieve fault simulation, so the high-speed rail power supply test system failure In part, both to simulate failure of power supply system, and there is safety while also saving resources.
