Foreword
GB/T 15166 "high-voltage AC fuse", is divided into the following sections.
--- AC high voltage fuses term;
--- AC high voltage fuses - Part 2. limiting fuses;
--- AC high voltage fuses - Part 3. Spray fuses;
--- AC high voltage fuses - Part 4. Protection of shunt capacitors with external fuses;
--- AC high voltage fuses - Part 5. high voltage fuses for motor circuit fuse guide for the selection;
--- AC high voltage fuses - Part 6. transformers for high voltage circuit fuse fuse selection guidelines;
--- AC high voltage fuses - Part 7. voltage transformer protection fuse selection guidelines.
This section is GB/T Part of 215,166.
The partial modification using IEC 60282-1.2005 "high-voltage fuses - Part 1. limiting fuses" (6th edition). This portion
IEC 60282-1.2005 The main differences are.
--- Scope. according to the actual situation of China's power grid, removing the IEC 60282-1.2005 in nominal frequency of 60Hz within about
Yung; according to the division of labor of the industry, the applicable minimum system voltage of 1000V to the IEC 60282-1 3kV;
--- Rated voltage. remove the rated voltage value independent of China's power grid, according to GB/T 11022 power (or GB 156) listed
Pressure is given;
--- Added "factory test" chapter of the specific content.
This portion instead of GB 15166.2-1994 "AC high voltage fuses limiting fuses" and partially replace GB/T 15166.4-
1994 "Common test methods for AC high voltage fuses."
This part of GB 15166.2-1994 GB/T 15166.4-1994 and the main differences are.
--- The difference between standard system. This section contains the original GB/T 15166.4-1994 "AC high voltage fuses Common test side
Law "applicable sections. After this revision, the series will be standard with the IEC standard correspondence, original GB/T 15166.4-1994
Will be replaced;
--- Clear in this section does not apply occasions, such as with the striker and the switching means;
--- Use conditions, due to the sensitivity of the fuse on the ambient temperature, no exact quote GB/T 11022, and of the IEC 60282-1
List the contents of all;
--- Term increases "(fuse bases) isolation distance", "external insulation", "self-restoring insulation," "organic fuse" and "around
Temperature "and so on;
--- Ratings, in accordance with current IEC standards R10 and R20 increase the number of system parameters; also increased the "full range fuses the best
High temperature "and other parameters;
--- Design and structure, increasing the nameplate requirements;
--- Type test, increasing the transfer of the full range of fuse current breaking capacity test, oil tightness test; remove the GB 15166.2-
The 1994 indicator test, quenching test (only for outdoor products), waterproof test (only for outdoor products) and the Corona trial; clear
The fuse does not need to limit electromagnetic compatibility (EMC) test;
--- Adds a chapter, "special test";
--- Added "guide for the selection," one chapter;
--- Increasing the content of Appendix E and Appendix G.
This section of the Appendices A and E are normative appendix, Appendix B, Appendix C, Appendix D, Appendix F and Appendix G are informative appendices.
