摘要
提出一种新型的低压保护电器——电弧故障断路器,用于防止故障电弧引起失火。介绍了其工作原理和应用场合及该断路器的发展动向。指出该断路器优点在于,与过电流保护装置相比,检测范围更大;与剩余电流保护装置相比,无需接地。
A new low voltage protection apparatus the arc-fauh circuit interrupter was put forward to avoid fire by fault arc. The work principle, application field and development trend of this circuit interrupter were introduced. It was pointed out that the advantages of this circuit interrupter are bigger detection range comparing with over current protection device and no earthing comparing with residual current protection device.
