磁控管(以下称MAG)是微波炉的核心器件。它在高电压(4kV)、大电流(6.4A)、高频率(2500MHz)的环境下工作,容易损坏。MAG管一旦损坏了,微波炉就不能加热煮食了,这是勿容置疑的。然而,现实中由于MAG管制造技术的提高和保护措施的加强,导致不能微波加热的原因往往是高压电容器、高压二极管、电源保险丝等损毁,MAG管却完好无损。
Magnetron (hereinafter referred to as MAG) is the core of microwave ovens. It is high voltage (4kV), high current (6.4A), high frequency (2500MHz) environment, easy to damage. MAG tube once damaged, the microwave oven can not heat cooking, which is beyond doubt. However, in reality, due to the improvement of manufacturing technology of MAG tube and the strengthening of protection measures, the reason why microwave can not be heated is often caused by damage of high-voltage capacitor, high-voltage diode, power fuse, etc., but the MAG tube is intact.
