Difference and Its Cause 2008 14 References 15ForewordGB/T 26218 "under filthy conditions Insulators selection and sizing" is divided into five sections. --- Part 1. Definitions, information and general principles --- Part 2. AC system with porcelain and glass insulators --- Part 3. Polymer insulators for ac systems --- Part 4. DC system with porcelain and glass insulators --- Part 5. DC system with polymer insulators This section GB/T 26218 Part 2. The partial modification using IEC /T S60815-2.2008 "under filthy conditions Insulators selection and sizing of the second Part. AC system with porcelain and glass insulators "(in English). This section compared with the IEC /T S60815-2, an increase of 8.1 in double umbrella shape, it shows an increase of double umbrella pin type in FIG. Shape 7, alternately in the three umbrella umbrella pin type and double umbrella disc IEC /T S60815-2 included in the suspension of the same type. Taking into account China's national conditions, in using IEC /T S60815-1.2008, this section also made some changes. Provision about the technical differences Into the body and they are involved in terms of the margin of a single vertical line identification (︱). These are given in Appendix A technical difference Its list of different reasons for reference. For ease of use, this section also made the following editorial changes. a) "The technical specifications" replaced by "this section"; b) use a decimal point instead of a decimal comma ",". ","; c) Remove IEC /T S60815-1.2008 Foreword; d) The number of 3.2 to 3.1.1, 3.1.2 will be renumbered 3.3, 3.4 will be renumbered 3.2. In addition to editorial changes and additions Appendix A d) above the outside, this part of the rest of the reg number and IEC /T S60815-2.2008 Consistent. Part 1 and this section covers the GB/T 5582-1993 and all the technical content. This part of GB/T 5582-1993 and GB/T 16434-1996 compared to the relevant technical changes as follows. This section provides the method for determining RUSCD and more comprehensive method of its correction. GB/T 5582-1993 and GB/T 16434- Although all the provisions of the 1996 creepage (RUSCD same meaning and provisions of this Part) rating than the distance value, but none specified by shape adaptation Nature, shape parameters, and according to altitude, insulator diameter correction method creepage distance. This section provides a more comprehensive artificial pollution test parameters. GB/T 5582-1993 provides for a artificial contamination withstand value (in this RUSCD same meaning specified in section), but only relates to the solid layer method, unspecified salt spray method. Also in the solid layer method considers only ESDD, not considered NSDD. GB/T 16434-1996 artificial pollution test parameter is not specified. GB/T 26218 Part 1 and GB/T 5582-1993 and GB/T 16434-1996 related technical content changes, see the section Preface points. Part 1 of this section and instead of GB/T 5582-1993 "high-voltage electrical equipment external insulation pollution level", GB/T 16434-1996 "High voltage overhead lines and power plants, substations environmental contamination classification and external insulation selection criteria." Appendix A of this section is an informative annex. This part is proposed by the China Electrical Equipment Industrial Association.

High-voltage insulators used under filthy conditions Selection and sizing Part 2. AC system with porcelain and glass insulators1 Scope and purposeThis section GB/T 26218 under filthy conditions applicable to the exchange system is determined by the choice of porcelain and glass insulators and dimensions. This section It specifies the set insulators under certain environmental contamination derived its method for determining the potential performance of specific guidelines and principles. GB/T 26218.1 apply to this section. Infrastructure and methods of this section in GB/T 26218.1 described in detail. This section provides the user with the aim of. ● Contamination from the field (SPS) level is determined with reference to a unified specific creepage distance (USCD); ● assess the suitability of various insulator shape; ● RUSCD on insulator on the shape, size and position correction was necessary in order to determine USCD; ● If required, to determine the performance of insulators verify the selected appropriate test methods and parameters.2 Normative referencesThe following documents contain provisions which, through reference GB/T 26218 in this section constitute provisions of this section.

Note 1. This definition is different than the creepage distance is defined, where the use of the relative value of the maximum phase voltage of the device (for AC systems, typically Um/3). To phase The insulation value of this definition is three times the GB/T 2900.8-1995 defined creepage distance values. Note 2. Um for the highest voltage for equipment (see IEC 60050-604 in 604-03-01). Note 3. USCD usually mm/kV and is generally expressed as the minimum value indicated. 3.1.2 Reference Unified creepage distance referenceunifiedspecificcreepagedistance RUSCD Under this part of the pre-correction on the size, shape and location of the installation, etc. - initial value of the waste site USCD.
