(1) the electrical power is used for the control, operation, and indication of the various airplane systems on the ground and inflight. The electrical power is obtained from the battery, generator and ground support equipment. Is is controlled and monitored prior to distribution as 115 volt ac, 28 volt ac and 28 volt dc supply to using systems.
電源系統(tǒng)用于在飛行或地面飛機(jī)系統(tǒng)的控制、操作及指示。電源來源于電瓶、發(fā)電機(jī)及地面電源設(shè)備。它被控制并監(jiān)控優(yōu)先分配成 115V交流、28V交流及 28V直流提供給用戶系統(tǒng)。
(2) The alternating current power is supplied by two engine driven generators for normal infligt operation. A generator, driven by the auxiliary power unit, can supply all power for ground or flight operation。 power can be supplied on the ground through the external power (ac) receptacle. The dc power is supplied from the battery or conversion from the ac power.

正常飛行時，交流電由兩臺發(fā)動機(jī)驅(qū)動發(fā)電機(jī)提供。一臺發(fā)電機(jī)由輔助動力裝置驅(qū)動，能夠在飛行操作中提供各種電源。飛機(jī)在地面時可通過地面電源插頭由地面電源供電。直流電由電瓶或交流電轉(zhuǎn)換而來。

(3) The ac and dc power is distributed to the various system through the left and right load control centers in the flight compartment. The control and indication of the electrical system is from the P5 overhead panel in the flight compartment.

直流及交流電源在駕駛艙中通過左右 LOAD控制中心被分配到不同系統(tǒng)中去。電源系統(tǒng)的指示及控制位于駕駛艙 P5頂置面板上。

(4) The generators driven by the engine produce the ac power required by the airplane systems primarily for flight operation. The ac generator is rated at 50 kilovolt –amperes, 120/208 volts, 400Hz . The unit is without slip-rings.commutator, or brushes on either the main generator or the exciter. A complete generator assembly consists of an exciter generator, a rotating rectifier and a main gererator.

發(fā)電機(jī)由發(fā)電機(jī)驅(qū)動產(chǎn)生飛行操作中各系統(tǒng)所需的交流電。交流發(fā)電機(jī)額定功率為 50KV/A，120/208伏，400Hz，在每個主發(fā)電機(jī)或勵磁器上沒有匯流壞、換向器及電刷。一個完整的發(fā)電機(jī)組件上包括一個
激勵發(fā)電機(jī)，一個轉(zhuǎn)子整流器及主發(fā)電機(jī)。
