摘　　要：为提高供电可靠性， 配电系统将广泛使用新型自动化开关设备。串接分段器将馈电线分段， 从技术上讲可以减少故障时间， 缩小故障范围， 提高配电网自动化程度。从经济上考虑， 一方面可以减少用户的停电损失， 增加供电部门的经济效益， 另一方面， 电力部门为此要增加额外的设备投资。为了解决可靠性与经济性之间的矛盾， 研究了如何选择合理的开关设备数量及位置，To improve the reliability of power supply,new type automatic circuit breakers are widely used in distribution networks. Using sectionalizing breakers to divide feeders into sections,from the technical point of view,can reduce the outage time and the length of faulty line section,and upgrade the automation level of the system.From economic point of view,this,on one hand,diminishes the power outage losses of consumers and increases the profits of power suppliers,but on the other hand,the power supplier should increase additional equipment investment.In order to solve the contradiction between reliability and investment,this paper addresses how to reasonably select the number and location of circuit breakers,and performs the economic analysis for the selection.
