防爆发电机三相突然短路试验探讨

Approach on Sudden Short-circuit Test for Explosion Protected Three-phase Generator

防爆发电机突然短路试验是为了考核电机的抗短路故障能力,在防爆发电机突然短路时,高温和热量(弧光短路)会造成壳体烧穿现象。目前国家还没有防爆发电机三相突然短路试验的相关标准,文章针对防爆发电机三相突然短路故障危害的分析,探讨了防爆发电机突然短路试验的相关依据,提出了防爆发电机三相突然短路试验的新方法。

The ability against short - circuit fault of explosion protected generator is verified by sudden short - circuit test. While the generator is in the case of suddenly - applied short circuit, it would be caused bread- through by the high temperature or arc light short circuit. At the present time, there is no standard for sudden short - circuit test on Ex generator. It approaches on the correlative gist to sudden short - circuit test on Ex generator by analyzing the dangerous and risk caused by suddenly - applied short circuit fault on the three phases of Ex generator. A new method on such test has put forward.
