INTRODUCTION The aircraft uses both 115 Volts AC and 28 volts DC power. AC electrical power is provided by two engine-driven generation systems. Each system includes an integrated drive generator (IDG) and a generator control unit (GCU). An auxiliary power unit (APU) generator is also available as a back AC power source to replace either or both IDGs. In the event of total AC power loss, emergency AC power is available from an in-flight air-driven generator (ADG). The ADG assembly is stowed in a compartment on the right side of the nose section. DC power is supplied by five transformer rectifier units (TRU) which rectifies AC input power into DC output power. Another source of DC power is from a main battery and APU battery. The main and APU batteries are connected into the aircraft DC electrical power system and are charged by their respective battery chargers. Power for starting the APU is provided by the APU battery. Electrical contactors, switches and relays located throughout 13 junction boxes in the aircraft, are used for connecting AC and DC power to the appropriate buses and components. Power connection is dependent on system configuration and health. The following is a list of all the aircraft electrical system buses: AC BUSSES DC BUSSES DC BUS 1 AC BUS 1 DC BUS 2 DC ESSENTIAL BUS AC BUS 2 DC SERVICE BUS AC ESSENTIAL BUS LEFT AND RIGHT BATTERY BUS AC SERVICE BUS DC EMERGENCY BUS ADG BUS DC UTILITY BUS 1 AC UTILITY BUS 1 DC UTILITY BUS 2 AC UTILITY BUS 2 MAIN BATTERY DIRECT BUS APU BATTERY DIRECT BUS On the ground, the aircraft can receive external AC power through a receptacle located on the forward right side of the fuselage. The aircraft can also receive external DC through a receptacle located on the aft right side of the fuselage. The electrical power services panel (EPSP) in the flight compartment, and the external service panel on the right forward fuselage, contain the AC and DC system control switches. The switches are used for manual and automatic control of the electrical power generating www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：Bombardier_CRJ_00-Electrical
