微波炉所用的电容不是普通的变压电容,而是一种带有“磁漏”特性的高压变压器,应用“磁漏”原理做到给微波炉磁控管灯丝电压,阳极电压自动稳压的目的,由于存在漏感电压相位滞后的影响,会使微波炉对电能的应用效率降低,而高压电容的电抗特性恰恰与漏感电压特性相反,电流相位超前,对相位滞后的漏感电流具有很好的补偿作用。
微波炉高压电容为什么会出现大火的情形:
1、由于维护不好,磁控管量输出器严重积污,微波炉工作时先将油污加热,温度高了自然构成打火。将炉腔、量输出器、通风口清洁洁净,平常定期进行清洁,打火即消掉。
2、倍压整流高压导线与底盘间隔太近或碰壳,若高压导线绝缘差或遇湿润空气即发作打弧。调整离压导线远离底盘,必要时加绝缘板绝缘。
3、用500型万用表×10K欧电阻档,红黑棒调来调去充放电测,阻值在“无量大‘∝~400KΩ”之间变化,表示电容量正常。假如只是电容的问题,当然彻底的方法就是改换高压电容器。
