摘要
直流供配电系统应用越来越广泛,时间常数是直流供配电系统以及低压直流断路器的重要参数,对直流断路器分断电流性能影响很大,不同的直流应用领域,其负载的时间常数不同,直流供配电系统保护断路器应选择直流专用产品,时间常数也是直流断路器设计、试验和选择的重要参数依据,只有适应相关的时间常数,直流断路器才能确保每一次分断都做到精确的保护和极致的安全。
DC power supply and distribution system is more and more widely used, the time constant is a DC power supply and distribution system and the important parameters of low voltage DC circuit-breaker, breaking current performance has great effect on DC circuit-breakers, DC requirements of different applications, different time constants, the DC power supply and distribution system protection circuit-breaker should choose DC special products, important parameters according to the time constant is the DC circuit-breaker design, test and choice, only to choose the proper time constant, DC circuit-breaker can ensure that every time breaking do accurate safety protection and perfection.
