二、TEXT：
(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.
電源系統用于在飛行或地面飛機系統的控制、操作及指示。電源來源
于電瓶、發電機及地面電源設備。它被控制并監控優先分配成115V
交流、28V 交流及28V 直流提供給用戶系統。
(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，交流電由兩臺發動機驅動發電機提供。一臺發電機由輔
助動力裝置驅動，能夠在飛行操作中提供各種電源。飛機在地面時可
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
統中去。電源系統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.
發電機由發電機驅動產生飛行操作中各系統所需的交流電。交流發電
機額定功率為50KV/A，120/208 伏，400Hz，在每個主發電機或勵磁
器上沒有匯流壞、換向器及電刷。一個完整的發電機組件上包括一個
激勵發電機，一個轉子整流器及主發電機。
(5) The exciter consists of a six – pole dc field and a rotating armature. The
exciter field is supplied with dc power from the voltage regulator. This
causes a 3-phase voltage to be developed in the exciter armature. The
3-phase voltage is rectified and fed into the ac generator rotating field. The
rotating field generates the useful 115v output voltage in the ac stator.
勵磁器上包括一個6 柱直流磁場和一個轉子電樞。激勵磁場由電壓調
節器來的直流電源提供，使得在勵磁電樞中引出3 相電壓。這3 相電
壓被整流并注入交流發電機轉子磁場，在交流定子電樞輸出可用的
115V 電壓。
(6) The constant speed drive(CSD) is located on the left side of the engine, on
the front of the accessory gearbox. The purpose of the CSD is to convert
the variable speed of the engine to a constant speed for the driven
generator to produce ac power at constant frequency.
恒速傳動裝置位于發動機的左側，附件齒輪箱前面。恒速齒輪箱的作
用是將發動機變化的速度轉換成恒速，以使發電機產生恒頻交流電。
(7) The electrical power for the ground operation of all electrical loads on the
airplane is supplied by an external 3-phase, 115vlot , 400Hertz alternating
current system. The power is supplied through an external power
receptacle. The ac external power receptacle is located on the right side of
the airplane forward of the nose wheel well.
飛機在地面進行操作時，使用外部的3 相115v，400Hz 交流電源。外
部電源通過一個外部電源插座連接飛機系統。外部交流電源插座位于
飛機前輪艙右側。
(8) The battery is located in the electronic compartment, left side just forward
of the E2 rack. The purpose of the battery is to provide dc power to critical
airplane systems in absence of normal dc supply from the transformer
rectifier. It is also used as a backup power for the ac system control and
protection and for starting the APU.
電瓶安裝于電子設備艙，E2 架左側。電瓶用來在無法通過轉換整流器
得到正常直流電時為飛機關鍵系統提供直流電。同時也作為直流系統
控制、保護及APU 啟動的備用直流電源。
(9) Three transformer rectifier units are located in the electronic compartment
on E3 rack. The purpose of the 3 transformer rectifiers is to convert 115
vlot ac ,400Hz, 3-phase power to 28 vlot dc power for use by the
airplane’s systems.
3 個整流器組件位于電子設備艙E3 架上。他們的作用是將115v，400Hz
交流電轉換成飛機系統使用的28v 直流電。
(10) The purpose of electrical power distribution system is to provide and
