GB/T 20139.1-2016Electrical insulation systems -- Thermal evaluation of modifications to an established electrical insulation system (EIS) -- Part 1: Wire-wound winding EIS (English PDF)

Foreword

GB/T .20139 "Electrical insulation system has been rated for electrical insulation system (EIS) component adjusted thermal evaluation" contains two section.

Part 1. scattered winding EIS;

Part 2. Forming Windings.

This part is part 1 of GB/T .20139.

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

This part of the GB/T .20139-2006 "electrical insulation structure has been determined on the level of scattered winding insulation structure components the overall thermal assessment method ", compared with GB/T .20139-2006 main technical changes are as follows.

--- modified the standard name;

--- full text "electrical insulation structure" to "electrical insulation system";

- modified the standard range (see Chapter 1, Chapter 1 of the 2006 edition);

--- increase the "enamel winding wire" and other 11 terms (see 3.1 ~ 3.7 and 3.10 ~ 3.13);

--- modified Figure 1 (see Figure 1, 2006 version of Figure 1);

Figure 2 to Figure 7 (see Figure 2 to Figure 7);

- an increase of "phase or earth insulation alternative" (see Chapter 5);

--- modified "winding wire replacement" (see Chapter 6, Chapter 6 of the 2006 edition);

--- Added "compatibility between composite materials" (see Chapter 10);

- Added "complete thermal aging test" (see Chapter 12).

This part uses the translation method equivalent to the use of IEC 61858-1.:2014 "Electrical Insulation System has determined the level of electrical insulation system (EIS) component evaluation of heat assessment Part 1. scattered winding EIS ".

1 Scope

This part of GB/T .20139 specifies the required level of electrical insulation system (EIS) components to adjust the heat resistance assessment of the required test Inspection procedures.

This section applies to EIS with a diffuser winding electrical installation.

The test procedure in this section is to compare the performance of the insulation system to be evaluated with the reference insulation system. Insulation systems according to IEC 60505 Has proven operational experience, or has been evaluated according to a test procedure in the IEC 61857 series of standards.
