适用范围:
This section recommends an appropriate and convenient sample whereby insulating systems for small random-wound direct-current field coils may be subjected to the exposures and conditions outlined in Section to simulate and evaluate their behavior in service. It is felt that the one insulation specimen as defined in the following will adequately represent direct-current field coils as used in small integral-horsepower motors and of 600 V or less rating. Other specimens may be required to… read more represent machines in the fractional-horsepower range as well as other than random-wound coils. read less
