低压配电线路保护电器的上下级保护选择性

The Upper-stage and Lower-stage Selective Protection of the Electric Appliances on the Low-voltage Distribution Line

根据《低压配电设计规范》对配电线路本级的要求以及对低压配电线路保护电器上下级保护选择性的要求,探讨了采用低压断路器作为配电线路保护电器的形式及其在实际应用中的选择问题。

Based on the requirements of <the Low-voltage Distribution Design Code> for the distribution line its self and the upper-stage and lower-stage selective protection of the electric appliances on the low-voltage distribution line, this paper probes into the forms of adopting the low-voltage circuit breaker as the protector of the low-voltage line and the problem of its selection in the actual application.
