GB/T 1029-2005 Test method for three-phase synchronous motors3 test equipment requirementsInter-turn impulse withstand voltage test equipment should meet the following requirements. --- Instrument uses a capacitor discharge ringing as inter-turn test voltage. Between manufacturer and user Unless otherwise specified, the capacitance It is set to 5 times the number of discharges. The first peak voltage apparent front time for 0.2μs (tolerance +0.3 -0.1μs) Or 1.2μs (Tolerance ± 30%), the former first priority wave time is 0.2μs. Two --- instrument output voltage shock wave should be symmetrical (with a tolerance of ± 3%). Allows the instrument to a single set of output voltage shock wave or a single group Converted into two groups impulse voltage impulse voltage wave output. The maximum impulse voltage peak --- instrument output should be able to satisfy the relevant test requirements for the highest Test Limits, a tolerance of ± 5% or ± 3%, the first priority ± 3%. Impulse voltage peak --- instrument output should be continuously adjustable, and there are instructions or pre-programmed. --- Instrument should be able to clearly distinguish the waveform display and waveform scanning frequency adjustable. --- Instrument shall be capable of continuous reliable operation. --- Instrument should be equipped with a dedicated test line, a reliable ground terminal and the necessary safety warning facilities, test conversion wiring should be convenient and reliable.4 Test methods and limits4.1 DC 4.1.1 Inter-turn impulse withstand voltage test Assessment for inter-turn insulation voltage to withstand the impact of capacity, quality control insulation between turns. Impulse voltage generated by the discharge of the capacitor is directly applied to the lead wire between poles or magnetic coil windings. Single pole test coil should be set aside on the ground well insulated shelf. Magnetic coil mounted stator (or rotor) after the root can It is necessary to take pole coil winding part or the entire winding turn test, with the rest of the test coil or wire winding not vote again related to the magnetic circuit Lead end turns or windings should be shorted together with a core grounding to prevent an induced voltage in the coil. Helical coil rewind rewind It must be provided with an insulating layer between turns. Interturn short circuit determination waveform comparison method can be used to test waveform with the normal waveform is a coil or winding comparison waveform consistent in compliance. You can use other effective identification method. Waveform comparison may or winding a coil in the normal state and abnormal state of the waveform into the case Comparing, you can compare two identical coil or winding waveform specification. When two coils or windings tested, it should be both ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 22717-2008_English be delivered?Answer: Upon your order, we will start to translate GB/T 22717-2008_English as soon as possible, and keep you informed of the progress.
