Problems solved by technology

[0002] Most of the existing motor testing devices are large-scale fixed engineering equipment, which generally can only test motors in normal temperature air, or are only suitable for testing the signs of high temperature and normal pressure of large equipment, and cannot test the working conditions of the equipment under operating conditions. It is even more impossible to accurately test the working performance of the motor under high pressure and high temperature and high pressure
At present, there is no test device specially designed to test the performance of motors in high temperature and high pressure environments

Embodiment Construction

[0018] The high-temperature and high-voltage motor testing device of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] Such as figure 1 As shown, the high-temperature and high-voltage motor testing device of the present invention includes a high-pressure sealed cavity, and the high-pressure sealed cavity is composed of a cylindrical sealed cavity shell 6 and a small end face of a pressure-bearing joint 3, a booster cylinder 13, and a booster piston 14. Used to create a high-pressure sealed environment filled with hydraulic oil. A high-pressure watertight head and a cable outlet 18 are installed on the pressure-bearing joint 3, which are mainly used to connect the control signal line inside the high-pressure sealed cavity with the control signal line outside. In addition, there is a small hole in the center of the pressure joint 3. The diameter of the small hole is preferably 0.5 mm, and the...

Abstract

The invention discloses a high temperature high-voltage motor testing device, which includes a cylindrical seal cavity shell, a pressure cylinder and a pressure piston thereof are provided in the cylindrical seal cavity shell, the pressure cylinder, the pressure piston and a bearing joint at the end of the seal cavity shell forms a high pressure seal cavity in the seal cavity shell, the inner of the high pressure seal cavity is filled with hydraulic oil, and a motor fixing sleeve for fixing the motor is mounted in the high pressure seal cavity. The apparatus can test operation situation and operating performance of the motor under and high voltage surroundings.

Description

technical field [0001] The present invention relates to a testing device, more particularly, to a testing device for a high temperature and high voltage motor. Background technique [0002] Most of the existing motor testing devices are large-scale fixed engineering equipment, which generally can only test motors in normal temperature air, or are only suitable for testing the signs of high temperature and normal pressure of large equipment, and cannot test the working conditions of the equipment under operating conditions. It is even more impossible to accurately test the performance of the motor under high pressure and high temperature and high pressure. At present, there is no test device specially used for testing the performance of motors under high temperature and high pressure environment. [0003] For this reason, it is necessary to provide a test device suitable for testing the operating conditions and performance of the motor in a high-temperature and high-pressure...
