摘要
中低压母线保护目前的现状一般不配置专用的快速母线保护是符合国内的典型设计做法。通过对2015年发生的两起事件进行比较,结合保护的原理及动作时间分析原因,说明中低压系统母线装设弧光保护的必要性。中低压系统母线装设弧光保护可使开关等主要设备损失降到最低,为变电站无人值守及坚强智能电网的建设提供必要的保障。
The current status of the medium and low voltage bus protection is generally not configured, the special fast bus protection is in line with typical domestic design practices. 33n-ough the comparison of two incidents happened in 2015, and analyzing the cause of the principle of protection and the time of action, It is said that the necessity of the installation of arc protection in the medium and low voltage bus system. The middle and low voltage system busbar is equipped with arc protection, which can minimize the loss of the main equipments such as switches, and it provides the necessary guarantee for substation unattended operation and the construction of strong intelligent power grid.
