摘要
10 kV供电系统是电力系统直接面对用户的一个重要环节,而且10 kV线路故障率相对较高。文章针对10 kV低压系统自身的特点,着重讨论低压线路中励磁涌流、所用变压器保护及低压线路保护中几个易被忽视的继电保护问题,并针对问题提出了解决方法。
10 kV power supply system is an important step to directly face the customer, and fault rate of 10 kV transmission line is high. In the light of the characteristics of 10 kV low voltage system, some protection problems easy to be neglected, such as magnetizing inrush, auxiliary power transformer protection, low voltage transmission line protection are discussed in detail. Related solutions are put forward as well.
