高效电机节能,是不可否认的事实。但实际应用中有网友留言,对高效电机持一种相对抗拒的态度,PFSA103C 3BSE002488R1主要表现为两种倾向:
一种:成本高
PFSA103C 3BSE002488R1不少电机使用者很在意电机的采购价格,在权衡更换电机与节能效果的投资情况;特别是PFSA103C 3BSE002488R1 对于电机使用频度不高的情况,大多数采用被动态度;当然,对于电机使用频度较高、用电量较大的场合,高效电机的整体节能效果非常明显,电机使用者对于高效电机也有较大的采购兴趣。
二种:实际节能效果不明显
PFSA103C 3BSE002488R1一位网友留言,某市在2009-2011做过用电企业的电平衡检测,1100多家企业,每年累计运行时间在3000小时以上的电机只占到20%左右,而且还不一定是接近额定负载。PFSA103C 3BSE002488R1 不少的电机在运行时负载率不足,直接影响到高效电机的节能效果发挥。按照电机的工作原理,当负载达到或接近其额定值时,电机的效率高,而轻载运行的电机并不能体现出其节能效果。
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.
