Test method for motor under high-temperature and high-pressure environment

Abstract

The invention relates to a test method for a motor under a high-temperature and high-pressure environment and belongs to the technical field of motor characteristic testing under the high-temperature and high-pressure environment. The test method includes the following steps that: a measured motor and an accompanying motor are arranged in a high-pressure and high-temperature sealed barrel; the measured motor works in a motor state, and the accompanying 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 accompanying motor works in a motor state; the stator current of the accompanying 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-temperature and high-pressure environment. According to the test method, required parameters are measured through utilizing a motor which has the same specification as the measured motor.

Description

technical field [0001] The invention belongs to the technical field of motor characteristic testing under high temperature and high pressure environment. Background technique [0002] With the continuous increase of human demand for resources and energy, motors, which are essential execution and functional components in exploration and development, will be more and more used in various extreme environments, such as high temperature and high pressure environments, and Before the actual application of the motor, its performance must be tested to verify whether it can meet the application requirements, and some necessary performance parameters should also be given. However, most of the existing motor test methods are suitable for normal temperature and pressure conditions, and some of the test equipment used cannot work in a high temperature and high pressure environment or the high temperature and high pressure environment will seriously affect its measurement accuracy.
