| 摘 要： | 本文调用电磁暂态计算程序(UBC版本),在考虑了开关特性和系统不同工况的条件下,计算了多断口断路器合闸电阻的通流容量。计算结果表明,开关特性中同极不同期对合闸电阻的通流容景影响最大;通流容量与系统开机容量、线路长短及合闸电阻两侧系统电源的相位差有关。通过以上工作,可以确定计算合闸电阻通流容量最大值时应取用的系统条件。

Calculation of Current Carrying Capacity of the Closing Resistor in Multi-break Circuit Breaker |
| |
| Abstract: | The energy of closing resister in multi- interrupter circuit breaker was calculated with EMTP (Electric Magnetic Transient Program. U.B.C. Edition), and the impacts of switching performances and system conditions were considered. The results of calculation indicate that in the switching performances the single-pole asynchronization has greatest influence on the energy.The energy depends on the unit-operating capacity of system, length of lino and the phase angle difference of sources both sides of the closing resister. The system condi tions for evaluating the maximum energy have been determined. |
