铁路信号智能电源屏,是指采用模块化电力电子技术,具有实时监测、报警、记录和故障定位功能的供电设备。智能电源屏虽制式众多,但它们具有共同的技术特征。其最主要的技术特征是设有监测单元,具有自动监测功能,实现了电源系统的实时状态和故障的监测及远程监控和管理。此外,各种智能电源屏都不同程度地实现了模块化,即将各种交、直流电源按用途设计成不同的模块,用户根据需要选择模块,构成供电系统。智能电源屏广泛采用电力电子技术,包括无触点切换技术、逆变技术、锁相技术、软开关技术、功率因素补偿技术、并联均流冗余技术、安全防范技术等,以保证供电系统的可靠性。
Railway signal intelligent power screen, refers to the use of modular power electronics technology, with real-time monitoring, alarm, recording and fault location of the power supply equipment. Although the smart power screen many formats, but they share the same technical characteristics. Its main technical features are monitoring units, with automatic monitoring capabilities to achieve real-time power system fault status monitoring and remote monitoring and management. In addition, a variety of intelligent power screen are to varying degrees to achieve a modular, is about to pay a variety of AC and DC power according to the purpose designed into different modules, the user according to need to select the module to form the power supply system. Intelligent power screen widely used power electronics technology, including contactless switching technology, inverter technology, phase-locked technology, soft-switching technology, power factor compensation technology, parallel current-sharing redundancy technology, security technology to ensure that the power supply system reliability.
