摘　　要：化工、钢铁等企业是高耗能企业,随着国家在节能降耗方面一系列优惠政策的出台,越来越多的化工企业根据自身生产状况,在逐步落实节能降耗,高压变频器的应用越来越广泛,诸如在焦化厂煤气鼓风机、除尘风机、以及循环水泵,炼铁厂烧结风机,炼钢厂转炉一次二次除尘风机等重要负载上的应用,高压变频器的应用不仅为化工企业降低了生产成本,提高了产品竞争力,还因其调节性能好,可以改善风机和电动机启动,会延长设备的使用寿命。本文针对传统的煤气鼓风机系统的耗能问题,采用高压变频技术对其进行变频改造,以达到节能增效的目的,最后通过对改造前后的数据分析计算,证明了使用该技术的可行性。The chemical,iron and steel enterprises belong to the high energy-consuming industry. With the implementation of a series of preferential policies for energy-saving and consumption-reducing in our country,the more and more chemical enterprises combine with their own production conditions to gradually implement the energy-saving and consumption-reducing project,and the applications of the high-voltage frequency converters are becoming more and more wide. Aiming at the energy consumption problem in the traditional gas blower system is transformed. The high-voltage frequency conversion technology is adopted to transform the system so as to achieve the energ-saving and efficiency-increasing purpose. Finally,the feasibility of using this technology is proved by the calculation and data analysis before and after the system transformation.
