Hunan Posts and Telecommunications Research Institute and other units developed by DC non-stop power supply combined with reasonable structure, low cost, easy maintenance and other characteristics of the vast rural branch offices have been widely used. However, in the course of maintenance and use, due to the carelessness and carelessness of the operation and maintenance personnel, the positive and negative polarity of the battery are connected in reverse, causing the phenomenon that the battery is reversely powered by the rectifier to cause the burning equipment, which is a dry load Battery, no initial charge, as long as the right amount of electrolyte can be used.
