|
摘要
给出瞬态恢复电压(TRV)波形调节电阻值的确定原则,计算以二进制取值的并联连接电阻器组的最小电阻值,导出电阻器组可接出的不同电阻值的总数、电阻值的分布密度以及电阻器组最小并联数的计算式。分析了合成回路中被试断路器正常开断和开断失败时电阻器吸收的能量和施加其上的电压。
The principle to determine the resistance for transient recovery voltage(TRV) control is given.The minimum value of resistor bank in parallel by binary setting is calculated. Calculating expressions are deduced for total amount of resistance value, for its distribution density and for minimum number of resistors in parallel. Energy absorbed by resistor and voltage applied to resistor when test circuit breaker breaks successfully or not in synthetic circuit are analysed.
