关于一次重合闸装置的研究

Research of Once Reclosing Device

用试验和理论计算的方法,对一次重合闸装置执行元件的选择和电容器的选配,进行了研究分析,结果认定DM—1型电码继电器作为装置的执行元件,使装置性能稳定,动作可靠,比DZ—50型中间继电器更适宜。同时,认定在保持电容器一定充电时间常数的条件下,以选择电容量较大的电容器配较小的电阻值的充电电阻器,以及用两只电容器并联代替一只相同电容量的电容器时,使装置性能更加稳定,提高装置动作的可靠性,并便于生产。

With the option of once reclosing device executor match up with a condenser, we have done analysis with experiment and theoretical calculation. Finally, we found that with the option of DM-1 code relay as the executor, it will make the equipment more reliable and stable. More suitable than DZ- 50 relay. Additionally,If we keep the time constant term（τ） the same, it is more reliable to choose a bigger condenser match up with a smaller charge resister, also parallel two condenser to instead of a same capacity condenser is more reliable and easy for manufacture.
