Introduction
High-voltage AC fuse products are widely used in power transmission and distribution systems with a nominal voltage of 3kV and above in my country, as well as in factories, mines, and small residents.
In the area, and as a protection device for lines, motors, transformers, fuses and other equipment. In this regard, my country has issued GB/T 15166
"High Voltage AC Fuse" standard. GB/T 15166 aims to establish the design, rating, test and special use of high-voltage AC fuses
The criteria for occasion selection are proposed to be composed of 8 parts.
--- Part 1.Terminology. The purpose is to provide common terminology for the standards within the system.
--- Part 2.Current-limiting fuses. The purpose is to put forward normative requirements for high-voltage AC current-limiting fuses.
--- Part 3.Jet fuses. The purpose is to put forward normative requirements for high-voltage AC jet fuses.
--- Part 4.Fuses for external protection of shunt capacitors. The purpose is to provide the special work of the fuse for the external protection of shunt capacitors.
specific additional requirements.
--- Part 5.Guidelines for the selection of fuses for high-voltage fuses for motor circuits. The purpose is to protect the motor circuit
The special case of fuses imposes special additional requirements.
--- Part 6.Guidelines for the selection of fuses for high-voltage fuses for transformer circuits. The purpose is to protect the transformer circuit
The special case of fuses imposes special additional requirements.
--- Part 7.Guidelines for the selection of fuses for high-voltage fuses for voltage transformers. The purpose is to protect the voltage transformer
The special case of fuses imposes special additional requirements.
--- Part 8.Tutorials and application guidelines. The purpose is to guide the selection of fuses under different operating conditions.

content.
This document is mainly applicable to the fuses of the fuses used in the direct starting motors of 3kV and above, 50Hz AC system.
Note. This document is also applicable when the motor used has auxiliary starting, but attention should be paid to the selection of the rated current of the fuse, see IEC TR62655.2013
5.2.3, and consult the manufacturer of the fuse.
Fuses conforming to this document apply to IEC 60282-1 and are intended to withstand normal operating conditions and motor starting pulses.

This document does not have terms and definitions that need to be defined.
4 Technical Requirements
4.1 Time-current characteristics of fuses
Compared with fuses used for power distribution system protection, fuses used for motor circuit protection should have.
---The fuse with a large melting current (slow action) should be within the 10s range of the pre-arc time-current characteristic as much as possible to obtain the correct motor
The maximum withstand (capacity) of starting current;
---Fuse elements with a small melting current (fast action) should be within the range of the pre-arc time-current characteristic below 0.1s as much as possible, and the relevant
Maximum short-circuit protection for switchgear, cables and motors and their terminal boxes.
Therefore, the pre-arcing time-current characteristics of fuses used in motor circuits shall be within the following limits.
When Ir≤100A, If10/Ir≥3;
When Ir >100A, If10/Ir≥4;
