摘　　要：介绍了高压全范围限流熔断器在国外发展的情况,阐述了我国正在研究开发的一种创新的大容量高压真空式全范围限流熔断器。该真空式熔断器主要是利用了真空熔断器具有十分稳定的开断小过负荷电流的特点和石英砂填料熔断器具有显著开断短路电流的限流作用,使其互相配合而成的新型全范围熔断器。它具有许多特点,如对于任何预期电流,在熔体熔化起弧后的第1次电流过零或第2次电流过零时就能灭弧,且无过电压,功率损耗小等。The development condition abroad of current limiting fuse with whole scope and high voltage was introduced, and the whole scope and vacuum type current limiting fuse with large capacity and high voltage was elaborated, which was devetoped in China. This vacuum type fuse is a new kind of whole scope current limiting fuse which is combined with the characteristic of opening small over bad current stably by using vacuum fuse and current limiting function of opening short - circuit current apparently by using quartz sand packing fuse. It has a lot of characteristics, such as for any prospective current, the arc can be extinguished after the current passes through zero point at first or second time when fuse - element melts, and there is no over voltage and power loss.
