电力变压器经济运行状态的判定

The Judgement of Economic Operation State of the Power Tanstormer

通过变压器的经济负荷计算 ,给出单台或两台并列运行的变压器 ,当负荷率长期偏低时 ,采用“以小换大”或“以单换双”

By caculating the economic load of a single transfor mer and double ones in parallel in the long term low load rate, we have propose d replacement criterions of transformer with a little one for a big one and a s ingle one for double ones.
