GB/T 15166.3-2023 High-Voltage AC Fuse - Part 3: Expulsion Fuse

The GB/T 15166.3-2023 standard specifies the requirements and test methods for expulsion fuses used in high-voltage AC systems. Expulsion fuses are essential components in power distribution systems, designed to protect equipment and personnel from overcurrent conditions.

This standard covers various aspects of expulsion fuses, including their construction, design, performance, and testing. It provides guidelines for the selection, installation, and maintenance of these fuses to ensure their safe and reliable operation.

Expulsion fuses work by utilizing the principle of arc extinction through the expulsion of gases generated during the fault current interruption. They are known for their excellent current-limiting capabilities and fast response time, making them suitable for high-voltage applications. Additionally, these fuses are designed to withstand high fault currents and provide reliable protection against short circuits and overloads.

The GB/T 15166.3-2023 standard aims to enhance the quality and performance of expulsion fuses, promoting their widespread use in high-voltage AC systems. Compliance with this standard ensures that these fuses meet the necessary safety and performance requirements, guaranteeing the protection of electrical networks and devices.

In conclusion, GB/T 15166.3-2023 sets the benchmark for expulsion fuses used in high-voltage AC systems. By adhering to this standard, manufacturers, installers, and users can ensure the efficient and reliable operation of these fuses, thereby safeguarding the integrity of power distribution systems.
