阻尼線圈 同步交換發(fā)電機(jī)的阻尼線圈是指嵌繞在轉(zhuǎn)子磁極間的導(dǎo)線,他們分別在兩極用端環(huán)或端板相連接,主要功能是削弱因負(fù)載變化而引起的波形畸變。Ampacity Ampacity is the safe current-carrying capacity of an electrical conductor in amperes as defined by code. 載流容量 載流容量是以安培數(shù)來定義導(dǎo)線安全載流能力。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 安培是電流單位。1伏電壓作用于1歐姆的電阻上就會產(chǎn)生1安培的電流。
Annunciator An annunciator is an accessory device used to give remote indication of the status of an operating component in a system. Annunciators are typically used in applications where the equipment monitored is not located in a portion of the facility that is normally attended. The NFPA has specific requirements for remote annunciators used in some applications, such as hospitals. 指示器 指示器作為一個(gè)附屬裝置常用于遠(yuǎn)程顯示系統(tǒng)的各個(gè)組成部分的運(yùn)行狀態(tài)。指示器通常使用在監(jiān)測設(shè)備不在設(shè)備現(xiàn)場的應(yīng)用。
美國國家防火協(xié)會對指示器在某些行業(yè)的應(yīng)用有特殊要求,例如醫(yī)院等。Apparent Power Apparent power is the product of current and voltage, expressed as kVA. It is real power (kW divided by the power factor (PF. 視在功率 視在功率是電流和電壓共同作用的產(chǎn)物,用kVA表示。它等于有功功率(kW)除以功率因數(shù)。Armature The armature of an AC generator is the assembly of windings and metal core laminations in which the output voltage is induced. It is the stationary part (stator in a revolving-field generator. 電樞 交換發(fā)電電機(jī)樞的是金屬芯和繞組的總成,產(chǎn)生感應(yīng)電壓。
電樞是旋轉(zhuǎn)磁場交換發(fā)電機(jī)的不動(dòng)部分(定子)BBackup Protection Backup protection consists of protective devices, which are intended to operate only after other protective devices have failed to operate or detect a fault. 后備保護(hù)裝置 后備保護(hù)裝置是在其他保護(hù)裝置動(dòng)作失敗或發(fā)生故障時(shí)動(dòng)作的保護(hù)裝置。Bandwidth The amount of data that can be transmitted in a fixed amount of time. For digital devices, it is expressed as bits per second, or bytes per second. For analog devices, it is usually expressed as cycles per second, or Hertz. 帶寬 在固定時(shí)間內(nèi)可傳輸?shù)臄?shù)據(jù)量。在數(shù)字化設(shè)備中以位/秒或字/秒表示。
在模擬(數(shù)字)設(shè)備中以周/秒或赫茲表示。Base Load Base load is that portion of a building load demand which is constant. It is the "base" of the building demand curve.
