一种新型微波炉用高压电容的设计及一体化研究

摘要

High voltage capacitor is the key part of microwave oven, which has an important influence of the high and low energy efficiency of microwave oven. Combined with the working experience, this paper designs a kind of dry type high voltage capacitor with self-healing effect used in microwave oven, replacing the existing oil-immersed capacitor. The kindling point of this newly designed capacitor is above 900℃, which has no oil spill risk and secondary pollution caused by it;and the cost is about 5%lower than the existing capacitors. In addition, this paper has an integration research on high voltage capacitor and high voltage diode, so as to install and use easily, and improve the production efficiency.%高压电容器是微波炉的关键部件之一，对微波炉的能效高低具有重要影响。本文结合工作实际，设计了一种具有自愈性的微波炉用干式高压电容，以替代目前在用的油浸式电容。新设计的电容着火点在900℃以上，不存在漏油风险和由此造成的二次污染，且成本比在用电容低5%左右；此外，本文对高压电容和高压二极管进行了一体化设计，以便于安装使用，提高生产效率。
