提高通信设备供电系统质量的措施

Measures for the improvement on the power supply quality of the communication equipment

针对铁路沿线的供电现状 ,如电压和频率波动经常大大超过允许范围 ,电网超负荷工作或受雷击造成的停电等现象 ,就怎样保证行车调度的安全可靠性和提高通信设备供电系统质量 ,提出了提高供电系统电源质量的 4种方法 ,同时 ,就电源过载时能够自身保护和不停电检修 。

As far as the present condition along the railway is concerned,the voltage and the frenquency waves often exceed the limits which are usually allowed.The power failure is often caused by the overloading of the electric network or struck by lightening.In order to ensure the safety realiabity of dispaching and improving the power supply system quality of the communication equipment,four methods have been put forward.Meanwhile,the voltage stabilizers of the anti_interferrence parameters and the methods direction of UPS for non_interruption power source are introduced so as to obtain a self_protection of power source overloading and overhauling while the power is on.
