Foreword

GB/T 32350 "Rail insulation coordination," consists of two parts. --- Part 1. Basic requirements for electric and electronic equipment clearances and creepage distances; --- Part 2. over-voltage and related protection. This section is GB/T Part of 232,350. This section drafted in accordance with GB/T 1.1-2009 given rules. This section uses redrafted law revision using IEC 62497-2.2010 "rail Insulation coordination - Part 2. over-voltage and phase Off guard. " This part of IEC 62497-2.2010 technical differences exist, the terms of these differences have been involved in the blank position by its outer margin Vertical single line (|) have been identified, their differences and for the following reasons. --- On normative references, this part has been adjusted technical differences, in order to adapt our technical conditions, the adjusted situation Focus is reflected in the status of Chapter 2, "Normative references", the specific adjustments are as follows. ● Modify with international standards of GB/T 1402-2010 instead of IEC 60850.2007 (see Chapters 1 and Table 1); ● Modify with international standards of GB 11032 instead of IEC 60099-4 (see 4.2.3); ● Remove the informative appendix cited IEC 61992.5, references and moved with GB/T 25890.5 substitute; ● Remove the informative Appendix Table 1 and note references IEC 60099-1, moved by reference. --- Change a table footnote a 1, and consistent with GB/T 1402-2010 Table 1 footnotes. This part made editorial changes as follows. --- Increased in Chapter 4 of Appendix A note of explanation "(fast transient overvoltage within 1MHz see Appendix A)"; --- Remove the informative appendix A in Figure A.1 above Note 1, Note 2 of Notes to change, because this section is deleted Introduction, Chapter 3 also No reference to Appendix A; --- Modify the references, instead of international documents with national standards.

3 Terms and Definitions

The following terms and definitions apply to this document. 3.1 Voltage 3.1.1 Overvoltage overvoltage Peak is greater than any voltage under normal operating conditions the highest steady-state voltage spikes. 3.1.2 Temporary overvoltage temporaryovervoltage Since the duration of voltage variation due to the relatively long overvoltage. Note. The temporary overvoltage and network independent of the load, the characteristics described by the voltage/time curve. 3.1.3 Transient voltage instantaneousovervoltage Since the duration of the current transfer due to only a few milliseconds or less short-term over-voltage. Note. The transient voltage depends on the network load, which is not characteristic voltage/time curve is described. Transient over-voltage current is mainly passed from the source to the load (network Network) results. 3.1.3.1 Operating Overvoltage switchingovervoltage Due to a specific operation or malfunction-off-off, transient, occurring in the system at any position on the overvoltage. [GB/T 16935.1-2008, the definition 3.7.3] ......
