Four-dimensional by the Beijing State Power Clean Energy Technology Co., Ltd. to develop and produce high-voltage inverter, Miyun, Beijing Economic Development Zone in East Kyrgyzstan Road 1, Tianjin Dongli Development Zone,glue gun letter channel 6, Huaneng Weihai Power Plant completed the type test and a complete success.
Measured output voltage of the device is only 1% of the relative harmonic content is high frequency trade and a major technological breakthrough.
Type test AC voltage test basis for the GB/T12668.4-2006/IEC 61800-4:2002 "speed electric drive systems Part IV: General requirements more AC voltage not exceeding 1000V AC 35kV rated speed electric drive systems value of the rules. " Main technical parameters: Model specifications SWdrive-MV06/2400-Y, rated voltage 6kV, the rated current of 231A, the nominal capacity of 2400kVA.
Products through insulation test, light load test, rated current test, over-current proficiency testing, power factor and the determination of power loss and efficiency, temperature rise test, control, inspection device characteristics (output voltage relative content), check protection, over current protection test (150% Ie protection), protective function test (sub-closing surge), audio noise, electromagnetic compatibility test, glue stick the net content of 13 side current distortion swab test validation, test results are in line with the requirements of inspection basis.
SWdrive-MV06/2400-Y 6000V rated voltage under the conditions of operation, the output current of 209.9A, frequency 50HZ, the measured output voltage of the inverter device relative harmonic content U11.00%, U20.95%, U31.02 %. According to the test type test basis, the relative harmonic content of the output voltage should be ≤ 4%, shows this key technology for the Beijing State Power Clean Energy Technology Co., Ltd. in the four-dimensional high-voltage converter has an absolute advantage in the industry.
The type testing by the Beijing State Power Clean Energy Technology Co., Ltd. dimensional pre-sales technical support engineers, field test and commissioning engineers and technicians have completed power plant, high frequency harmonic content of the output voltage of the relative frequency of about 1% of the industry and a major technological breakthrough, greatly reducing the pollution of the power system, one harmony with the environment.
