Dc panel (DC)
Product introduction
CTD intelligent dc power source screen design with reference to the ministry 《DL/T5044-2004\》, 《JB / 5777.2-2002》 and 《JB / 5777.3-2002》 technical standards related to production, can meet reliable transmission and distribution system is normal or abnormal condition of dc control power supplies and high and low voltage switch points of switching power supply requirements. It is widely used in the variable sub-station under 500 kv and below 600000 KW dc operation power supply requirements of power plants.
