【摘要】 对330kV电网的线路断路器和变压器断路器是否取消合闸电阻进行了研究，由操作过电压的计算结果得出了线路断路器和变压器断路器可以取消合闸电阻，在建和拟建的变电所也可以采用不带合闸电阻的断路器．更多还原

【Abstract】 This paper studies the subjects on removal of closing resistors of line circuit breakersand transformers breakers in 330kV power network. The result of switching overvoltage study issumeiently described.The study concludes that removal of closing resistors of line breakers andtransformer breakers is feasible.It is also feasible to use breakers without closing resistors in Xin-ing and Yuanshan substation being built.更多还原
