Test method of motor under normal-temperature and high-pressure environment

Abstract

The invention relates to a test method of a motor under a normal-temperature and high-pressure environment and belongs to the technical field of motor characteristic testing under the normal-temperature and high-pressure environment. The test method includes the following steps that: a measured motor and a standby motor are arranged in a high-pressure sealed barrel; the measured motor works in a motor state, and the standby motor works in a generator state; the stator current of the measured motor is gradually decreased to 0.5-times rated current from 1.5-times rated current; the stray loss of the measured motor working in the motor state is P; the measured motor works in a generator state, and the standby motor works in a motor state; the stator current of the standby motor is gradually decreased to 0.5-times rated current from 1.5-times rated current; the stray loss of the measured motor working in the generator state is P<Gs>; the average value P<->s of the stray loss of the load of the measured motor can be obtained based on the above measured parameters and calculation results. With the test method of the invention adopted, the parameters of the motor can be detected under the high-pressure environment. According to the test method, and stress acts on the whole motor, and therefore, the direction of the stress borne by the motor is more diverse, and thus, the test method has a very bright application prospect.

Description

technical field [0001] The invention belongs to the technical field of motor characteristic testing under normal temperature and high pressure environment. Background technique [0002] With the continuous increase of human demand for resources and energy, and there are extremely rich resources and energy needed by human beings in the ocean, the exploration of ocean resources is inseparable from motors as executive and functional components. , the pressure on the motor is also gradually increasing, so whether the motor can work normally under high-voltage conditions has become a key factor restricting the exploration and collection of deep-sea resources. Before the motor is used in deep-sea exploration, it should be accurately tested in the high-voltage environment where it may work Evaluation is crucial, and accurate testing also provides relevant basis for motor optimization. In view of the fact that most of the existing motor test methods are suitable for normal temperat...
