窗体顶端 英汉电力术语对照 AC Alternating Current (AC) is electric current that alternates between a positive maximum value and a negative maximum value at a characteristic frequency, usually 50 or 60 cycles per second (Hertz). 交流 交流是指电流在正负最大值之间以特定的频率变动，通常频率为50或60赫兹。 ANSI American National Standards Institute.? 美国国家标准协会 美国国家标准协会 Acoustic Material Acoustic material is any material considered in terms of its acoustic properties, especially its properties of absorbing or deadening sound. 声音材料? 声音材料，特指有吸音或隔音特性的材料。 Active Power Active power is the real power (kW) supplied by the generator set to the electrical load. Active power creates a load on the generator set’s engine and is limited by the horsepower of the engine. Active power does the work of heating, turning motor shafts, etc. 有功功率 有功功率（kW），是指发电机组实际供应给负载的功率，它由发电机组的发动机提供，受到发动机马力大小的限制。发热和驱动马达转动靠有功功率完成。 Air Circuit Breaker An air circuit breaker automatically interrupts the current flowing through it when the current exceeds the trip rating of the breaker. Air is the medium of electrical insulation between electrically live parts and grounded (earthed) metal parts.? 空气线路断路器? 空气线路断路器的功能是当电流大小超过断路器的过流跳脱设定值后自动断开。空气是带电零件和接地金属零件之间的绝缘介质。 Alternator Alternator is another term for AC generator. 交流发电机 交流发电机 Amortisseur Windings The amortisseur windings of a synchronous AC generator are the conductors embedded in the pole faces of the rotor. They are connected together at both ends of the poles by end rings or end plates. Their function is to dampen waveform distortion during load changes. 阻尼线圈 同步交流发电机的阻尼线圈是指嵌绕在转子磁极间的导线，他们分别在两极用端环或端板相连接，主要功能是减弱因负载变化而引起的波形畸变。 Ampacity Ampacity is the safe current-carrying capacity of an electrical conductor in amperes as defined by code. 载流容量 载流容量是以安培数来定义导线安全载流能力。 Ampere? The ampere is a unit of electric current flow. One ampere of current will flow when a potential of one volt is applied across a resistance of one ohm. 安培 安培是电流单位。1伏电压作用于1欧姆的电阻上就会产生1安培的电流。 Annunciator? A
