摘要
针对关口表供电电源实际运行存在的问题,介绍了关口表供电电源的工作方式、变电站的交流、直流和交流不间断电源系统类型及其可靠性,并从关口表、变电站电源系统、接线方式三方面探讨了提高关口表供电电源可靠性的措施。
Aiming at the practical operating problems of power supply source in gateway meter, the operating modes of the power supply source, AC, DC and AC UPS system types and their reliability in the station is introduced. Measurements to enhance the reliabili- ty of the power supply source are discussed in three ways of gateway meter, power supply system of station and wiring method.
