This section replaces the following previously issued as follows. --- GB/T 20111.1-2006.IntroductionThis section provides a standard test procedure, according to IEC 60505 by comparing the electrical insulation system (EIS) to evaluate life expectancy Estimated EIS. One kind EIS contains many different components, the choice of ingredients should be able to withstand all kinds of electric generating electrical products in different parts of the structure, Mechanical and thermal stresses. The useful life of the EIS process depends on the combination of components, each component and interaction between the components of the overall EIS Electrical properties, mechanical properties of the role. Therefore, the provisions of a representative of all the electrical products test is not possible. IEC equipment technical committee Have responsibilities under test and the test procedures to meet their specific application requirements. Through this technology between the Committee and other technical committees Cooperation to continue the work to develop a series of parts, each set forth a particular test and/or applications. This section allows only approximate comparison, and so can not be fully determined to any characteristic of a particular EIS, which can only be based full-featured extensions Operating experience to be obtained. Electrical insulation systems - Procedures for thermal evaluation Part 1. General requirements for low-voltage1 ScopeThis section GB/T 20111 specifies the electrical insulation systems (EIS) Universal thermal evaluation and testing procedures for identification, assessment EIS to be established Test procedures and performance comparison of a reference EIS. This section applies to voltage 1000V and below, the heat factor is the main factor of the aging of existing or proposed EIS used in electrotechnical products.2 Normative referencesThe following documents for the application of this document is essential.
