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

Abstract：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.
