Abstract

The invention discloses a high-voltage synchronous motor testing device, comprising a three-phase voltage regulator and a voltage monitoring device. An input end of the three-phase voltage regulator is connected with a power supply network, and an output end is connected with the input end of a microcomputer comprehensive protector. The voltage monitoring device is connected with two ends of a liquid resistor. Through adoption of the high-voltage synchronous motor testing device, a differential protection test and a liquid resistor resistance value test of a high-voltage synchronous motor canbe realized at the same time, so test efficiency of the high-voltage synchronous motor is improved, and test duration is reduced. The invention also discloses a method for carrying out a test throughutilization of the high-voltage synchronous motor testing device.

Description

technical field [0001] The invention relates to the technical field of equipment testing, in particular to a testing device and testing method for a high-voltage synchronous motor. Background technique [0002] Large-scale high-voltage synchronous motors above 10KV are widely used in metallurgical projects such as sintering main exhaust motor systems and hot rolling main drive systems due to their excellent constant speed performance and power angle characteristics. Due to the complex physical process and difficult control of the high-capacity high-voltage synchronous motor, it is extremely difficult to start. It is precisely because of its high power, high voltage, involving multiple control links such as soft start and excitation, so the start-up test of large-scale high-voltage synchronous motors has the characteristics of comprehensiveness, importance, and technical complexity. The test technology of many large-scale high-voltage synchronous motors in China They all sta...
