变频电源应用时的一些技巧

一.变频线路敷设与信号处理

1、交流变频电源闭环控制一般都是正作用的,即输入信号大,输出量亦大(例如中央空调制冷工作时及一般压力、流量、温度等控制时)。但亦有反作用的,即输入信号大,输出量反小(例如中央空调在制热工作时以及供热站的取暖热水泵)。

6、信号变换器在变频电源外围电路中亦被经常用到,一般由霍尔元件加电子线路组成。按信号变换和处理方式可分为电压变电流、电流变电压、直流变交流、交流变直流、电压变频率、电流变频率、一进多出、多进一出、信号叠加、信号分路等各种变换器。

(2)因只有一个控制信号,所以输出频率一致,即同频率,这样压力亦一致,不存在湍流损耗。

(3)节省成本。只要一套传感器及PID

(4)更有利的是,因为系统只有一个控制信号,即使3 台泵投入不同,但工作频率却相同(即同步),压力亦一致,这样湍流损耗为零,亦即损耗最小,所以节电效果最佳。

SI、BIANPINDIANYUANYONGYUFEIHENGGONGLVXINGFUZAIDEJIDIANFENXI:

(1)由于某些负载特性起动转矩大,起动困难的设备,例如挤出机、清洗机、甩干机、混料机、涂料机、混合机、大型风机、水泵、罗茨鼓风机等均能顺利起动了。这比通常提高起动频率进行起动效果明显。使用此法再配合由重载变轻载措施,提高电流保护到最大值,几乎一切设备都能起动了。因此说采用减小基底频率来提高起动转矩是最有效的,亦是最方便的办法。
