摘要
针对北方联合电力有限责任公司包头第二热电厂长期存在的两路热控直流电源合环不独立、非隔离双电源结构等问题,通过改造,将两路直流系统经DC/AC隔离变换器转换后并联输出,保证了热控直流电源的无扰切换,实现了两路热控直流电源系统的完全电气隔离。
Issues of nondependent power closing loop for two-way thermal control DC power, and non-dual isolating power structure through the transformation existed for a long term in Baotou No.2 Thermal Power Plant, North United Power Co., Ltd. Through retrofit, two DC system after the conversion of the DC/AC isolation converter in parallel output to ensure that no disturbance of the thermal control DC power switch and to achieve complete electrical isolation of the two thermal control of DC power systems.
