自从2000年第一套信号智能化电源屏通过铁道部技术鉴定起,至少有六家企业的智能化电源屏产品进入铁路市场。铁路客运专线信号系统大量使用各种智能电源屏,而信号系统的重要性决定了信号智能电源屏必须使用UPS系统。在实践中掌握UPS系统电路原理,不断摸索其使用与维护的规律,并逐步加以规范。这对于提高信号设备供电的安全性、可靠性及延长UPS系统使用寿命都有着十分重要的意义。
Since 2000, the first set of signal intelligent power screen through the Ministry of Railways technology appraisal, at least six companies intelligent power screen products into the railway market. Railway Passenger Line signal system extensive use of a variety of intelligent power screen, and the importance of the signal system determines the signal intelligent power screen must use the UPS system. In practice, the principle of the UPS system circuit, and constantly explore the law of its use and maintenance, and gradually be standardized. This is of great significance for improving the security, reliability and prolonging the service life of the UPS system of the signal equipment.
