济南变频器维修:软启动器生产商谈怎样挑选软启动器的额定电流许多触碰过软启动器的大家都了解,软启动器的额定电流基础全是标在出厂铭牌上的,而这一额定电流包括了键入侧及其輸出侧分别的额定电流。那麼在平时应用中,该怎样对软启动器的额定电流开展挑选,毕竟这个跟变频器的使用效果息息相关。今天变频器生产厂家就来和你一起探讨这个问题。


Jinan inverter maintenance: the soft starter manufacturer talks about how to select the rated current of the soft starter. Many people who have touched the soft starter know that the rated current basis of the soft starter is all marked on the factory nameplate, and this rated current includes the rated current of the input side and the output side respectively. How to select the rated current of soft starter in normal application, after all, it is closely related to the use effect of frequency converter. Today, the frequency converter manufacturer will come to discuss this problem with you.


一.关于选择输入侧的额定值。


I. about selecting the rating on the input side.


变频器厂家表达,键入侧的额定电流关键为工作电压和相数。而针对中小型容积的软启动器键入工作电压的额定电流一般 有这几类(全是相电压): 第一类是普遍的380V/50Hz、三相电的,此类早已运用于绝大部分机器设备中,很广泛


According to the inverter manufacturer, the rated current at the input side is the working voltage and the number of phases. The rated current of input working voltage for small and medium volume soft starters generally includes these types (all phase voltage): the first type is 380V / 50Hz, three-phase electric, which has been widely used in most of the machine equipment.


第二类是200~230V/50Hz或是是60Hz、三相电的,这种关键运用在進口的机器设备当中。 第三类就是200~230V/50Hz、单相电的,这类潜心用以小容积的机器设备和或是某些家庭装的家用电器中。


The second type is 200-230v / 50Hz or 60Hz, three-phase electric. This key is used in imported machinery and equipment. The third type is 200-230v / 50Hz, single-phase, which is dedicated to small volume machinery and equipment or some household appliances.


二.关于选择输出侧的额定值。


II. About selecting the rating of the output side.


额定输出电压,是指变频器输出电压中的最大值。在绝大多数的情况之下,它就是输出频率等同于电动机额定频率时的输出电压值。变频器生产厂家表示,一般情况下,没有特殊的应用情景,变频器的额定输出电压的值钱都是和输入电压的额定值相同。


Rated output voltage refers to the maximum output voltage of the frequency converter. In most cases, it is the output voltage value when the output frequency is equal to the rated frequency of the motor. According to the manufacturer of frequency converter, in general, there is no special application scenario, and the value of rated output voltage of frequency converter is the same as that of input voltage.


额定输出电流值(IN),主要是指变频器能够连续输出的最大交流电流的有效值,变频器生产厂家强调,用户们主要就是根据这个数值来选择合适的变频器。


The rated output current (in) mainly refers to the effective value of the maximum AC current that can be continuously output by the frequency converter. The manufacturer of the frequency converter emphasizes that the user mainly selects the appropriate frequency converter according to this value.


适用电动机功率。主要是指以4极的标准电动机作为标准对象,厂家表示,这代表在额定输出电流以内能够驱动的电动机功率的范围值。


Applicable to motor power. It mainly refers to the standard 4-pole motor as the standard object, which represents the range value of motor power that can be driven within the rated output current according to the manufacturer.


变频器的过载能力,主要是指它输出电流超过额定电流的所许可的范围以及时间段。绝大多数的变频器都定在150%IN、60s或者是180%IN、0.5s。而针对于类似风机、泵类的负载调速的变频器则常定在120%IN、60s。


The overload capacity of frequency converter mainly refers to the allowable range and time period when its output current exceeds the rated current. Most frequency converters are set at 150% in, 60s or 180% in, 0.5s. The frequency converter for load speed regulation of similar fans and pumps is usually set at 120% in and 60s.


了解好变频器的基本参数以及根据具体使用情况选择是非常关键的,所以在购买的时候一定跟变频器生产厂家确认好,且有专业人士指导。


It is very important to know the basic parameters of the frequency converter and select according to the specific use situation. Therefore, it must be confirmed with the frequency converter manufacturer and guided by professionals when purchasing.
