GB/T 20111.2-2016Electrical insulation systems -- Procedures for thermal evaluation -- Part 2: Specific requirements for general-purpose models -- Wire-wound applications (English PDF)

Foreword

GB/T .20111 "Electrical insulation system thermal evaluation procedures" contains the following three parts.

- Part 1. General requirements Low pressure;

- Part 2. Particular requirements for general purpose applications;

Part 3. Particular requirements for enveloping coil models - Spray winding electrical insulation systems (EIS).

This part is part 2 of GB/T .20111.

This part is drafted in accordance with the rules given in GB/T 1.1-2009.

This part of the replacement GB/T .20111.2-2008 "Electrical insulation system electrical insulation system thermal evaluation procedures Part 2. General line Circle model of the special requirements scattered winding application ", and GB/T .20111.2-2008 compared to the main technical changes are as follows.

- the term "ground" "coil" (see 3.1, 3.3);

- New requirements for impregnation in model assembly (see 4.3, 4.3 of 2008);

- Change the "aging test cycle" to "Durability test cycle" (see 6.3.1 for the 2008 edition).

This part uses the translation method equivalent to IEC 61857-21.:2009 "Electrical insulation system thermal evaluation procedures Part 21. Universal mold Type of special requirements scattered winding application "(2nd edition).
