Abstract

Compared to conventional technologies based on low-frequency thyristor-controlled power-supply units, the high-frequency power-supply units of electrostatic precipitators, based on a new cutting-edge technology, ensure more efficient gas conditioning at thermal power plants and industrial enterprises. Particular attention in the design of high-frequency power-supply units should be paid to designing a step-up transformer with high nominal output voltage and capacity at an operational frequency from several to tens of kilohertz. The design features of this transformer significantly influence the characteristics of the whole high-frequency power-supply unit. This article proposes an approach to forming a broadband design transformer model which correctly works in a broad range of low and high frequencies. This model allows imitating processes in the transformer together with an external circuit; in this case, it is possible to analyze the influence of the transformer design on the characteristics of the whole unit, as well as the operating conditions of the transformer itself, which is especially important in the device design phase.

静电除尘器高频供电单元升压变压器的宽带模型

摘要

相较于传统的低频晶闸管控制电源装置技术，静电除尘器高频电源装置以全新尖端技术为基础，为火电厂和工业企业提供更高效的气体调节. 高频电源装置的设计应特别注意设计具有高标称输出电压和容量的升压变压器，其工作频率从几千赫兹到几十千赫兹。该变压器的设计特点对整个高频电源单元的特性有很大影响。本文提出了一种形成宽带设计变压器模型的方法，该模型可在广泛的低频和高频范围内正确工作。该模型允许与外部电路一起模拟变压器中的过程；在这种情况下，可以分析变压器设计对整机特性的影响，以及变压器本身的运行状况，这在装置设计阶段尤为重要。
