Introduction

High voltage AC fuse products are widely used in power generation, transmission and distribution systems with a nominal voltage of 3kV and above, as well as in factories, mines, and residential buildings. In this regard, my country has established a system to support high-voltage alternating current. GB/T 15166 series of national standards for high voltage AC fuse products. GB/T 15166 aims to establish the GB/T 15166 series of national standards for high voltage AC fuse design, The criteria for ratings, tests and selection for special applications are planned to consist of 8 parts. --- Part 1.Terminology. The purpose is to provide common terminology for standards within the system. --- Part 2.Current-limiting fuses. The purpose is to provide normative requirements for high-voltage AC current-limiting fuses. --- Part 3.Ejection fuses. The purpose is to provide standard requirements for high voltage AC ejection fuses. --- Part 4.Fuses for external protection of shunt capacitors. The purpose is to provide fuses for external protection of shunt capacitors, a special type of fuse. Special additional requirements may be put forward for different situations. --- Part 5.Guidelines for the selection of fuses for high-voltage fuses for motor circuits. The purpose is to protect motor circuits. This special operating condition of fuses poses special additional requirements. --- Part 6.Guidelines for the selection of fuses for high-voltage fuses used in transformer circuits. The purpose is to protect the transformer circuit This special operating condition of fuses poses special additional requirements. --- Part 7.Guidelines for the selection of fuses for high-voltage fuses used to protect voltage transformers. The special working condition of the fuse-link puts forward special additional requirements. --- Part 8.Application Guidelines. The purpose is to provide guidance for the selection of fuses under different operating conditions. This document combines information from previously published Parts 1 to 6, as well as new information. Information may be deleted during their future revisions.
