Changzhou Leading High-frequency Pulse Corona Resistance Tester
On July 30th, the “High-frequency Pulse Corona Resistance Tester†project jointly developed by Changzhou Weiyuan Electrical Equipment Co., Ltd. and Zhejiang Institute of Science and Technology passed the appraisal of the relevant expert group. The expert group unanimously held that: The equipment is of reasonable design, advanced technology, and the research results have reached the leading level in the country, with a wide range of market applications. High-frequency pulse corona resistance tester is mainly used for the detection of motor winding wire materials such as high-speed railways, wind power, rail transportation, and ore machinery that require frequency conversion control, and high-temperature and high-frequency resistance for corona-resistant enameled wire and corona resistant film-wrapped wire. Aging life test under pulse voltage. The test results provide help for the selection of large and medium-sized motor wire, which can effectively improve the operating life of the motor and reduce the occurrence of dielectric breakdown. At present, domestic existing high-frequency pulse corona resistance test equipment for winding wire, poor adaptability and stability of parameter settings, such as the number of test channels in parallel test will interfere with the test parameters, especially in the test process, the sample itself aging It is impossible to correct the deviation of frequency, pulse voltage, rising edge and duty cycle under the condition of load, which will affect the test accuracy and test results. The "High-frequency Pulse Corona Resistance Tester" (Version 2.0) jointly developed by Changzhou Weiyuan Electric and Zhejiang Institute of Science and Technology focused on the stability of parameters and the adjustability under load, and expanded the applicability of the equipment. The project equipment uses an independent adjustable pulse power supply, each test head independent operation, can be set to test different parameters, do not interfere with each other. Its main innovative advantages are: the parameters of each test head are independently adjustable; the frequency can be continuously adjusted when the test frequency is loaded; the adjustable range is 1KHz to 20KHz; the high-frequency pulse voltage can be continuously adjusted with an adjustable range of 0V-±1500V; The air-to-air ratio is continuously adjustable and the adjustable range is ≤50%. The rising edge load is continuously adjustable. The adjustable range is 50ns-400ns. It is understood that the project equipment has been selected by the National Electric Wire and Cable Quality Supervision and Inspection Center, Jiangsu Province Motor Testing Center and other third-party authoritative testing agencies and well-known enterprises in the industry.
