大中容量短路试验发电机主要设计特点

短路试验发电机又称冲击发电机,是一种专门用于短路试验的特殊发电机(电力系统的高压断路器、开关、变压器等元件进行短路电流开断、电强度、高瞬态电流等项试验).该机由小功率电动机拖动,当转速达到额定转速后,把空载电压下的机械能经短路后变为电能输送到被试品.本文围绕哈电机公司生产的短路试验发电机,介绍其主要设计特点.

The Main Design Features of Short-circuit-test-generators with Medium and Large Capacity

Short-circuit-test-generator(also called impact-generator) is a type of generator used specially for short-circuit tests,including opening short circuit,electric strength,high transient current tests on electric elements to be fixed in the electric power system such as high voltage breakers,switches,transformers and so on.Driven by a small-power motor up to rated speed,the generator transforms mechanical energy under no load voltage into electric energy through short-circuit and then transports it to the de...
