Title:
ROTATIONAL RISE ABNORMALITY DETECTION DEVICE OF A DYNAMO-ELECTRIC MACHINE, AND DYNAMO-ELECTRIC MACHINE UNIT
Document Type and Number:
WIPO Patent Application WO/2018/123538
Kind Code:
A1
Abstract:
The present invention is a rotational rise abnormality detection device (14, 20) for detecting abnormalities during rising of the rotation speed of a dynamo-electric machine (17) that performs powering by being energized, and is provided with a first determination unit, a second determination unit, and a comprehensive determination unit. The first determination unit determines that, when rotation starts for the dynamo-electric machine, a state for which there is energization to the dynamo-electric machine and the rotation speed of the dynamo-electric machine is less than a first rotation speed has continued for a first time. The second determination unit determines that the energization duration from the start of energization to the dynamo-electric machine is longer than a second time which is set to be greater than the first time, and that the rotation speed of the dynamo-electric machine is less than a second rotation speed which is set to be greater than the first rotation speed. The comprehensive determination unit determines that, when at least one of the determination by the first determination unit and the determination by the second determination unit is affirmed, the rising state of the rotation speed of the dynamo-electric machine is abnormal.
