工作原理
Working principle
中高频感应加热器主要由逆变器、谐振单元、变压器和感应器组成。其中逆变器是
一个交——直——交的变流器,将工频交流电能变换成为几千至几百千赫兹的中频或高
频电能。谐振单元和变压器一端连接逆变器,另一端连接感应器,将高压变成隔离的低
压并进行阻抗匹配。加热时,感应器中流过强大的高频电流,在导体内产生感应电流,
因此导体迅速被加热。中高频感应加热器的谐振频率根据被加热对象和工艺的不同而不
同一般从一千至几十千赫兹最为常用。
The medium and high frequency induction heater mainly consists of an inverter,resonant
unit,transformer,and inductor.The inverter is anAC to AC converter that converts power
frequency AC energy into intermediate or high-frequencyenergy ranging from several thousand
to several hundred kilohertz.One end of the resonant unitand transformer is connected to an
inverter,and the other end is connected to an inductor to convert the high voltage into an
isolated low voltage and perform impedance matching.During heating,a strong high-frequency
