Foreword
GB/T 20111 "thermal insulation electrical insulation procedures" is divided into the following sections.
--- Part 1. General requirements for low pressure;
--- Part 2. Thermal evaluation of general-purpose models requires winding winding applications;
--- Part 3. Thermal evaluation of encapsulated coil models requires winding wound electrical insulation system (EIS);
--- Part 4. Guidance on the selection of test methods for the assessment and classification of electrical insulation systems.
This section GB/T 20111 Part 4.
This section drafted in accordance with GB/T 1.1-2009 given rules.
This section uses the redrafted law to amend the use of IEC /T R61857-2.2015 "Electrical Insulation System Thermal Rating Part 2.
Select the appropriate test method to assess and grade electrical insulation system. "
This section and IEC /T R61857-2.2015 technical differences and the reasons are as follows.
--- Added "comment" in scope (see Chapter 1);
--- On the normative references, this section made a technical difference with the adjustment to adapt to China's technical conditions, adjust the situation
Concentration reflected in the second chapter "Normative references", the specific adjustments are as follows.
● Equivalent to the use of international standards GB/T 17948.1 replaced IEC 60034-18-21;
● Equivalent to the use of international standards GB/T 17948.3 replaced IEC 60034-18-31;
● Equivalent with the international standard GB/T 20111.1 replaced IEC 61857-1;
● Equivalent with the international standard GB/T 20111.2 instead of IEC 61857-21;
● Equivalent with the international standard GB/T 20111.3 instead of IEC 61857-22;
● Equivalent with the international standard GB/T 20112 instead of IEC 60505;
● Equivalent with the international standard GB/T 20139.1 replaced IEC 61858-1;
● Replace IEC 61858-2 with GB/T 20139.2 which adopts the same international standard;
● Equivalent with the international standard GB/T 22566 instead of IEC 62068;
● Replace GB/T 22578.1 equivalent to IEC /T S62332-1 with international standards;
● Replace IEC /T S62332-2 with GB/T 22578.2 equivalent to international standards;
● Equivalent to the international standard GB/T 23642 instead of IEC /T S61934;
● Replace GB/T 26170 equivalent to IEC /T S62101 with international standards;
● Increased reference to IEC /T S62332-3.
--- According to IEC /T R61857-2.2015 on the terms of the expression and understanding of the standard full text, the term "test/test mode
Type "to" Test Model "(see 3.2)," Packaging Equipment "to" Packaging "(see 3.4);
--- Modify the title of Chapter 5 to "Select test stress" (see Chapter 5);
--- Modify Chapter 6 of the contents of Table 1 to Table 4 to assess the performance type, test parameters to test stress, test subjects /
Evaluation purposes, compared with IEC /T R61857-2.2015 compared to the standard operability more favorable. Removed in Table 1 about positive

Thermal insulation of electrical insulation systems
Part 4. Assessment and classification of electrical insulation systems
Guidelines for selection of test methods
1 Scope
This section GB/T 20111 specifies the selection and classification of electrical insulation system test method selection guidelines. Provides for the assessment and grading
Electrical insulation system standard selection guidelines, but also provides a single factor or multi-factor stress assessment has established the selection of insulation system standards
Guidelines.
This section applies to the IEC standard operating voltage range of electrical products used in the established or proposed electrical insulation system.
NOTE The structure and expected operating conditions of electrical products are the basis for the selection of suitable test methods.
