摘要
通过对不同低压供电系统及接地型式中四极开关应用问题的具体分析,得出:四极开关的应用主要是为了满足保护性或与其它保护配合性的需要,而不是满足开关本身功能性的需要,使用时要根据规范规定和供电系统本身的需要选择使用.
On the basis of the analysisis of application of four-pole breaker in different low voltage power supply systems and different types of earth, it is conclude that the application of four-pole breaker is aimed at meeting the demands of protection and cooperation instead of the demand of the breaker itself, and the breaker must be used in accordance with the code and demand of low voltage power supply system.
