0.4 kV智能负荷转接箱的研制

Development of 0.4 kV Intelligent Load Transfer Box

文章研制了一套0.4 kV智能负荷转接箱,可实现发电机电源与市电电源瞬时切换,有效倒闸时间在2~3 s,大幅缩减发电机电源在架空线电源故障后的接入时间,减少停电时户数,提高供电可靠性。

With the rapid development of the operation technology of distribution network,the technical requirements of the live operation project of distribution network overhead line have been improved.This paper will study a set of 0.4 kV intelligent load transfer box,which can realize the instantaneous switch of generator power and mains power,effective switching time in 2~3 s,greatly reduce the access time of generator power after the overhead line power failure,reduce the number of households during power failure,and improve the reliability of power supply.
