This standard uses the translation method equivalent to IEC 60034-15..2009 "Rotating electrical machines Part 15. AC motors Stator forming coils Impulse voltage level "(third edition, english version) This standard replaces GB/T 22715-2008 "AC motor stator forming coil impact voltage level". With GB/T 22715- 2008, the main technical changes are as follows. - modified the scope of the standard (see Chapter 1, see Chapter 1 of the.2008 edition); --- Added terms (see Chapter 2); --- Increases the test level of the variable frequency motor coil (see Chapter 3); --- increase the tolerance of the relevant test parameters (see Table 1); - modified the tolerance of the wavefront time of the forward wave of the steep wave (see 4.2.2, 5.1.2.2 of.2008); - increased the voltage level of the inspection test (see 5.1); - Added instructions for the test (see Appendix B). This standard is proposed by China Electrical Equipment Industry Association. This standard is under the jurisdiction of the National Committee for Standardization of Rotating Electric (SAC/TC26).

Rotary AC motor stator forming coil Impulse voltage level1 ScopeThis standard specifies the test voltage applied to the main insulation and turn-to-turn insulation of the sample coil as well as the test procedure. This standard is applicable to AC motors made up of stator forming coils.2 terms and definitionsThe following terms and definitions apply to this document. 2.1 Sampling test sampletest Under the new conditions of use, the coils capable of adequately representing the final structure for the motor are tested. Its purpose is to evaluate the insulation junction The manufacturing method and process of the structure. 2.2 Check the test routinetest Tests on all coils of the motor. 2.3 Forming the stator coil form-woundstatorcoil A coil that has been machined, insulated and essentially complete before the stator is embedded. 2.4 Wavefront time fronttime T1 The time required for the peak voltage to rise from 0% to 100%. And is defined as the peak at 30% and 90% of the time interval 1.67 times. 2.5 Half-peak time time-to-halfvalue T2 The start and peak times are reduced to half the time interval.3 Impulse voltage levelThe withstand voltage level of the special rated voltage is calculated according to the formula given in Note 2 in Table 1. Table 1 gives some of the conventional rated voltage Of the impact voltage level and round the whole to the nearest integer value. The test level of the variable frequency motor depends on the rated voltage given by the manufacturer. Such as IEC 60034-18-42, taking into account the maximum overvoltage that may occur at the motor end, increasing the test level by a factor is When the. This coefficient can be as high as 1.7 for a three-level inverter, but if the level is more, the coefficient is lower. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 22715-2016_English be delivered?Answer: Upon your order, we will start to translate GB/T 22715-2016_English as soon as possible, and keep you informed of the progress.
