空冷风机变频器的应用和故障分析

空冷机组运行中,变频器的应用日益广泛,在增加经济效益的同时也引起了一系列问题。空冷散热器的变频器在日常应用中,尤其是夏季高温时段极易发生跳闸、报警问题,对空冷器真空度、运行负荷等均会产生影响,降低了机组运行安全性、经济性。文章针对风机变频器的应用、故障原因、应对方法等进行了探讨,旨在提高变频器的应用效果。

In the operation of air-cooled units, the frequency converter is increasingly widely used, which causes a series ofproblems while increasing economic benefits. The frequency converter of air-cooled radiator is easy to trip and alarm in daily application, especially in the high temperature period in summer, which will affect the vacuum degree and operation load of air cooler.The operation safety and economy of the unit are reduced. In this paper, the application of fan frequency converter, fault causes,countermeasures and so on are discussed in order to improve the application effect of the frequency converter.
