本文的目的是建立电阻式高温超导限流器的功能模型。故障限流器的开关元件在液氮低温恒温器中进行浴式冷却。这些元件由YBaCuO薄膜组成，它们沉积在不同的衬底上，其临界电流密度高达3/spl middot/10/sup 6/ A/cm/sup 2/。对于最有效的限制样品，迄今为止，峰值通过电流是额定电流的两倍，稳态短路电流低于额定电流。介绍了100 kVA功能模型的概念。
The aim of this work is to develop a function model of a resistive HTSC fault current limiter. The switching elements of the fault current limiter are bath-cooled in a liquid nitrogen cryostat. The elements consist of YBaCuO films which are deposited on different substrates with critical current densities of up to 3/spl middot/10/sup 6/ A/cm/sup 2/. For the most effective limiting samples so far the peak let-through current was twice tile nominal current and the steady short-circuit current below nominal current. The concept of a 100 kVA function model is introduced.
