浅谈万家寨水电厂直流220V高频开关电源装置改造

Discussion of Technical Transform to Power Supply Eguip of 220V DC.High-Frequency Switch

高频开关电源的智能化程度远远高于相控电源。近年来维护体制要求远程集中监控、无人值守或少人值守,故进行智能化高频开关电源改造非常必要。本文简要介绍万家寨水电厂220 V直流装置的改造过程,改造中出现的问题及新装置的优缺点。

With the rapid growing of computer technology nowadays, the high frenquency switch power supply gains gigantic development. The intellectual level of high frenquency switch power supply is higher greatly than that of the phase control power supply. Recently, the change that has appeared in the system of maintenance demands long-distance centralized monitor and control, nobody being on point duty or a few men. The article suggests the reforming process of 220V direct current equip in the Wanjiazhai hydro-power station, the problems during the process and the advantages and shortcomings of this installation.
