Foreword

GB/T 19071 "Wind Generator Asynchronous Generator" is divided into two parts. --- Part 1. Technical conditions; --- Part 2. Test methods. This part is the second part of GB/T 19071. This part is drafted in accordance with the rules given in GB/T 1.1-2009. This part replaces GB/T 19071.2-2003 "Wind Generator Asynchronous Generator Part 2. Test Method". Compared with GB/T 19071.2-2003, this section is subject to the following editorial changes. --- Revised the scope of application of the standard (see Chapter 1); --- Added normative reference document GB/T 1029 (see Chapter 2); --- Increased the content of safety measures in the test (see 3.1); --- Revised the requirements for test equipment (see 3.2); --- Increased appearance and mechanical inspection requirements (see 4.1); --- Increased the "the difference between the average value of the three-phase resistance and the three-phase resistance should be no more than 2% of the average value" (see 4.3); --- Increased phase sequence inspection requirements for windings (see 4.4); --- Removed the rule that the average temperature rise calculated by the thermal resistance method and the temperature difference of the hottest temperature measured by the temperature measuring component should not exceed 10K. Set (see 4.6, 4.4 of the.2003 edition); --- Increased the reference operating temperature of "different insulation heat classification (A, E, B, H") (see Table 1, 4.5.4.1 of the.2003 edition); --- Modified the stray loss calculation formula (see 4.7.4.3, 4.5.4.3 of the.2003 edition); --- Modified the overspeed test speed, from 1.2 times the rated speed to 1.2 times the maximum operating speed (see 4.9,.2003 edition) 4.7); --- Increase the blocking test method at rated frequency (4.13); --- Increase the overload test method (4.14); --- Increased current waveform distortion rate measurement (4.15); --- Revised the salt spray test method standard (see 4.20, 4.15 of the.2003 edition); --- Revised the standard for mold test methods (see 4.21, 4.16 of the.2003 edition). This part was proposed by the China Machinery Industry Federation. This part is under the jurisdiction of the National Wind Machinery Standardization Technical Committee (SAC/TC50).
