GB/T 13539.4-2016Low-voltage fuses -- Part 4: Supplementary requirements for fuse-links for the protection of semiconductor devices (English PDF)

Foreword

GB 13539 "Low-voltage fuses" currently includes the following six parts.

- Part 1. Basic requirements;

- Part 2. Supplementary requirements for fuses used by full-time personnel (mainly for industrial fuses) Standardized fuse system display Examples A to K;

- Part 3. Supplementary requirements for fuses used by unskilled personnel (mainly for fuses for household and similar purposes) Standardization Fuse System Examples A to F;

- Part 4. Supplementary requirements for fuse - links for the protection of semiconductor equipment;

- Part 5. Application guidelines for low - voltage fuses;

Part 6. Supplementary requirements for fuse - links for the protection of solar photovoltaic systems.

This section is part 4 of GB 13539.

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

Replacement of GB/T 13539.4-2009 "Low-voltage fuses" Part 4. Supplement to fuse-links for the protection of semiconductor equipment begging". The main technical changes in this part compared to GB/T 13539.4-2009 are as follows.

--- increase VSI (voltage source inverter) content, including VSI characteristics, technical requirements and test methods;

--- Table 101 "Conventional time and convention of" gR "and 'gS' type fuse-links", "gR" type No fusing current Inf From 1.1In Changed to 1.13In;

- Table 102 "complete test list" deleted the exchange No. 6 ~ No.10 test, added VSINo.21 test, and footnote a Modified as "if the ambient air temperature between 10 °C and 30 °C, arc I2t characteristics of effective";

--- Table 103 "The same fuse-fuse series of the smallest rated current fuse test list" deleted the exchange No.6 test and DC no.11 test;

--- 8.4.3.6 "Indicator device and impactor (if any) action" increase "indicates the performance and performance of the device or impactor verified by the manufacture Plant and user consultation ";

--- the original table 106 "verify the AC cut-off current, I2t characteristics and arc voltage characteristics of the test parameters" deleted, changed to the new table 106 "VSI fuse breaking capacity test parameters";

--- Appendix CC "CC.3B Bolt Connection Fuse System - DIN" and "CC.5A Contact Chip Fuse System" Increased the "gR 'and' gS 'fuse-type fuse time and the agreed current" table;

- Appendix CC North American fuse-link system increases the recovery voltage requirements of the breaking capacity test;

--- Appendix CC Added French B-type cylindrical cap fuse system.

This part uses the translation method equivalent to the use of IEC 60269-4.:2012 "Low-voltage fuses Part 4. Semiconductor device protection fuse Supplementary requirements ".

In this part of the normative reference to the international documents have a consistent correspondence between the following documents.

--- GB/T 321-2005 priority and priority series (ISO 3. 1973, IDT);

GB/T 5465.2-2008 Graphical symbols for electrical equipment - Part 2. Graphical symbols (IEC 60417DB..2007, IDT);

Low - voltage fuses - Part 1. Basic requirements (IEC 60269-1.:2009, IDT);

GB/T 13539.2-2015 Low-voltage fuses Part 2. Supplementary requirements for fuses used by professionals (mainly Industrial Fuses) Standardized Fuse System Examples A to K (IEC 60269-2.:2013, IDT);

- GB 13539.3-2008 Low - voltage fuses - Part 3. Supplementary requirements for fuses used by unskilled personnel (mainly for Household and similar fuses) Standardized fuse systems Examples A to F (IEC 60269-3.:2006, IDT).

This part makes the following editorial changes.

- to remove the preamble of international standards;

--- Figure CC.6 in the upper right there are three "x" cross-section symbols, two suspects are wrong, delete; the lower right of the figure "X detail 6)" doubt, change for "X detail 5)";

- "CC.6.1" (see CC.6.4) "is incorrect and changed to" (see CC.6.3) ".
