東莞發(fā)電機(jī)出租發(fā)電機(jī)組專業(yè)術(shù)語(yǔ)中英文對(duì)照大全及狀態(tài)參數(shù):
V
Voltage Control
The voltage control is a rheostat that sets the operating point of the voltage regulator and therefore controls the output voltage of the generator set, within its design limits.
電壓控制
電壓控制是設(shè)定電壓調(diào)整器的運(yùn)行點(diǎn)從而在設(shè)計(jì)范圍內(nèi)控制發(fā)電機(jī)組的輸出電壓的變阻器。
Voltage Dip
Voltage dip is the dip in voltage that results when a load is added, occurring before the regulator can correct it, or resulting from the functioning of the voltage regulator to unload an overloaded engine-generator.
電壓暫降
電壓暫降是在負(fù)荷增加而調(diào)整器還未能進(jìn)行校正時(shí)、或電壓調(diào)整器正在為過(guò)載的發(fā)動(dòng)機(jī)卸載時(shí)出現(xiàn)的電壓下降。
Voltage Regulation
Voltage regulation is a measure that states the difference between maximum and minimum steady-state voltage as a percentage of nominal voltage.
電壓調(diào)整率
電壓調(diào)整率描述的是最大和最小穩(wěn)態(tài)電壓差與額定電壓之間的百分比。
W
Watt-Hour Meter
A watt-hour meter records the total power output at a specific point in a system. Typical recording increment is in kW-hours.
電度表
電度表記錄系統(tǒng)中某一點(diǎn)的總電力輸出,通常以千瓦時(shí)為記錄單位。
Wye Connections
A Wye connection is the same as a star connection. It is a method of interconnecting the phases of a three-phase system to form a configuration resembling the letter Y. A fourth (neutral) wire can be connected at the center point.
Y連接
Y連接就是星形連接,也就是把三相系統(tǒng)中的相按照字母Y的形狀連接起來(lái),還可以在中心點(diǎn)接上第四根(中性)線。
Z
Zero Sequence
Zero sequence is a method of ground fault detection that utilizes a sensor (CT) that encircles all the phase conductors as well as the neutral conductors. The sensor will produce an output proportional to the imbalance of ground fault current in the circuit. This output is then measured by a relay to initiate circuit breaker tripping or ground fault alarm.
零序
零序是一種接地故障檢測(cè)方法,它使用一個(gè)傳感器(CT)來(lái)把所有相導(dǎo)體和中性導(dǎo)體連接在一起,傳感器會(huì)按照線路中接地故障電流的不平衡程度等比例地產(chǎn)生輸出,再由一臺(tái)繼電器來(lái)測(cè)量這一輸出,并斷開(kāi)斷路器或釋放接地故障警報(bào)。
