DC/DC变换器在一体化电源系统中应用时,对负载回路中出现的短路或持续过载故障,传统的热磁式断路器无法满足保护要求.介绍了一种具有超短延时特性的设备用断路器,能够满足电力系统的要求,可配合电厂、变电站一体化电源系统中DC/DC变换器的应用,节约工程制造成本.
Equipment Circuit Breaker with Ultra-Short Delay Characteristics
When DC/DC converter is applied in integrated power supply system,the traditional thermal-magnetic circuit breaker can not meet the protection requirements against short circuit or continual overload fault in load circuit.This paper recommends a type of circuit breaker for equipment with ultra-short delay characteristics.This breaker can meet the requirements of power system,suitable for the DC/DC converter application in the integrated power supply system of power plants and substations,and effective in cutting the project cost.
