Description
本实用新型涉及微晶玻璃技术领域，具体为一种感应电泄放电路。The utility model relates to the technical field of glass-ceramics, in particular to an induction electric discharge circuit.
微晶玻璃发热盘因热效率高、无辐谢等多种优势，逐渐被市场认可。但在高温(约300℃)条件下，微晶玻璃介电强度会下降，且不可避免，与其直接或间接接触的金属器件上会感应产生高电压(约110V)。去除感应电常规方法是直接接地线，因高温下的微晶玻璃发热盘感应漏电流较大，经常超过漏电保护开关极限电流而跳闸。Glass-ceramic heating discs are gradually recognized by the market due to their advantages such as high thermal efficiency and no radiation. However, under the condition of high temperature (about 300°C), the dielectric strength of the glass-ceramic will decrease, and it is inevitable that a high voltage (about 110V) will be induced on the metal device directly or indirectly in contact with it. The conventional method to remove the induced electricity is to directly ground the wire. Because the leakage current induced by the glass-ceramic heating plate at high temperature is relatively large, it often exceeds the limit current of the leakage protection switch and trips.
鉴于此，我们提出一种感应电泄放电路。In view of this, we propose an induction electric discharge circuit.
