摘要
中频电炉作为主要的加热感应设备,其产生的谐波污染对电网电能质量构成威胁。文中针对中频电炉存在的谐波问题,分析比对原有的治理措施,提出了新的谐波治理装置——中频电炉用有源电力滤波器,对其主电路结构及工作原理进行分析。并对有源滤波器在中频电炉上的节能成效进行了分析,分别从变压器、换相角、交直流电压变化等方面进行了能耗分析,最终计算出净节能达到6.2%,节能效果显著。
The intermediate frequency electric furnace has become the main induction heating equipment,generating harmonic pollution that poses a huge threat to the grid power quality. This article puts forward a new intermediate frequency electric stove with active power filter harmonic treatment device in view of the harmonic problems of intermediate frequency electric furnace. The main circuit structure and working principles are presented. The energy saving effect of the active filter on the intermediate frequency electric furnace is analyzed,and energy consumption by the transformer,the change in phase angle,and the change in ac / dc voltage is studied. The net energy saving is calculated to be 6. 2%,a significant energy-saving effect.
