高效電機(jī)節(jié)能,是不可否認(rèn)的事實。但實際應(yīng)用中有網(wǎng)友留言,對高效電機(jī)持一種相對抗拒的態(tài)度,PFSA103C 3BSE002488R1主要表現(xiàn)為兩種傾向:
一種:成本高
PFSA103C 3BSE002488R1不少電機(jī)使用者很在意電機(jī)的采購價格,在權(quán)衡更換電機(jī)與節(jié)能效果的投資情況;特別是PFSA103C 3BSE002488R1 對于電機(jī)使用頻度不高的情況,大多數(shù)采用被動態(tài)度;當(dāng)然,對于電機(jī)使用頻度較高、用電量較大的場合,高效電機(jī)的整體節(jié)能效果非常明顯,電機(jī)使用者對于高效電機(jī)也有較大的采購興趣。
二種:實際節(jié)能效果不明顯
PFSA103C 3BSE002488R1一位網(wǎng)友留言,某市在2009-2011做過用電企業(yè)的電平衡檢測,1100多家企業(yè),每年累計運行時間在3000小時以上的電機(jī)只占到20%左右,而且還不一定是接近額定負(fù)載。PFSA103C 3BSE002488R1 不少的電機(jī)在運行時負(fù)載率不足,直接影響到高效電機(jī)的節(jié)能效果發(fā)揮。按照電機(jī)的工作原理,當(dāng)負(fù)載達(dá)到或接近其額定值時,電機(jī)的效率高,而輕載運行的電機(jī)并不能體現(xiàn)出其節(jié)能效果。
The fact that efficient motors save energy is undeniable. However, in practical applications, some netizens have left comments expressing a relatively resistant attitude towards high-efficiency motors. PFSA103C 3BSE002488R1 mainly exhibits two tendencies:
One type: high cost
Many motor users of PFSA103C 3BSE002488R1 are very concerned about the purchase price of the motor, and are weighing the investment situation between replacing the motor and energy-saving effects; Especially for PFSA103C 3BSE002488R1, when the frequency of motor use is not high, most adopt a passive attitude; Of course, for situations where motors are frequently used and consume a large amount of electricity, the overall energy-saving effect of high-efficiency motors is very obvious, and motor users also have a great interest in purchasing high-efficiency motors.
Two types: The actual energy-saving effect is not significant
PFSA103C 3BSE002488R1, a netizen left a message stating that a certain city had conducted electricity balance testing for electricity consuming enterprises from 2009 to 2011. Among more than 1100 enterprises, only about 20% of the motors have accumulated operating time of over 3000 hours per year, and they may not necessarily be close to the rated load. Many motors in PFSA103C 3BSE002488R1 have insufficient load rates during operation, which directly affects the energy-saving effect of high-efficiency motors. According to the working principle of the motor, the efficiency of the motor is highest when the load reaches or approaches its rated value, while the energy-saving effect of the motor cannot be reflected in light load operation.
