设计遥测系统的时候,供电问题往往不为人们所重视,而系统投入运行之后,供电便成了影响设备可靠工作的重要因素。从国内各个遥测系统的运行情况统计来看,造成设备停止工作的事故中,有30～40％是由供电中断引起的。除此之外,非标准供电(如电压过低、过高等)也是引起设备不能正常工作的原因。这个问题已开始引起设计人员的普遍注意。

When designing the telemetry system, the power supply problem often does not pay attention to people. After the system is put into operation, the power supply has become an important factor affecting the reliable operation of the equipment. Statistics from the operation of various telemetry systems in China shows that 30% to 40% of the accidents that caused the equipment to stop working were caused by power interruptions. In addition, non-standard power supply (such as voltage is too low, too high, etc.) is also caused by the equipment can not work properly. This issue has begun to attract widespread attention of designers.
