Daily maintenance of telecom power supply
Under normal operation, high frequency switching power supply equipment has little maintenance workload, mainly dustproof and regular dedusting. Especially in the area where the climate is dry, the dust in the air is more and the dust will be deposited in the machine. When the air is wet, the host control disorder will cause the main engine to be disturbed and the inaccurate alarm will occur. A large amount of dust also causes poor heat dissipation in the device. Generally, every quarter should be thoroughly cleaned. The second is to check whether the connectors and plugging parts are loose or unfastened during the dust removal. Because rectifier can not eliminate instantaneous pulse interference, there is still interference pulse after rectification. In addition to the function of storing DC power, the equivalent capacitance of the battery is directly proportional to the capacity of the storage battery. Therefore, maintenance of battery work is very important, although the battery
