摘要

研制了一种2循环138千伏10000毫安(兆伏安)空气爆破断路器，并进行了现场试验。就目前所知，这是输电线电压的第一个2周期断路器。该断路器在安装在运输拖车上时，可中断传输线和母线故障。断路器的最大负荷为10230毫瓦。据信，这是在现场测试中对138千伏断路器施加的最高故障负荷。最长的中断时间为1.85个周期。断路器的额定值基于所提出的对称额定值结构。

A 2-Cycle 138-Kv 10,000,000-Kva Air-Blast Circuit Breaker Design Considerations and Field Tests at Philip Sporn Station

A 2-cycle 138-kv 10,000-mva (megavolt-ampere) air-blast circuit breaker has been developed and field tested. Insofar as is known, this is the first 2-cycle breaker for transmission line voltages. The breaker interrupted both transmission line and bus faults while mounted on the trailer on which it was shipped. The maximum breaker duty was 10,230 mva. It is believed this is the highest fault duty ever imposed on a 138-kv breaker in a field test. The longest interrupting time was 1.85 cycles. The breaker rating is based on the proposed, symmetrical rating structure.
