XRNT Fuse (English Introduction)
1. Definition & Core Features
A high-voltage current-limiting fuse designed for full-range protection in electrical systems, covering both short-circuit and overload scenarios67.
Voltage ratings: Supports systems up to 40.5kV, with common specifications including 3.6kV, 12kV, and 24kV6.
Current ratings: Adjustable fuse-element ratings (e.g., 0.5A–63A) to match diverse load requirements68.
2. Technical Specifications
Breaking capacity: High interrupting capability (up to 50kA) for rapid fault isolation, minimizing equipment damage78.
Design: Combines current-limiting and non-current-limiting mechanisms to protect against both low-level and high-level faults68.
3. Applications
Widely used in industrial power networks, wind turbine systems (40.5kV), and substations to safeguard transformers, capacitors, and switchgear67.
Compatible with gas-insulated switches and modular switchgear installations7.
4. Key Advantages
Full-range protection: Eliminates the need for multiple fuses by covering all fault currents from minimal to maximum thresholds68.
Fast response: Limits peak short-circuit currents, enhancing system safety78.
Standard compliance: Meets IEC/IEEE standards for medium- to high-voltage applications67.
5. Model Identification
Example: XRNT-40.5kV/31.5A denotes a 40.5kV-rated fuse with a 31.5A current capacity67.
This fuse type ensures reliable protection in critical infrastructure, balancing performance and adaptability67.
**Selection Criteria for High-Voltage Fuses**
1. **Transformer Rating**:
- The fuse must match the transformer's voltage, current, and fault level.
2. **System Voltage**:
- Ensure the fuse's rated voltage is equal to or higher than the system voltage.
3. **Fault Current**:
- The fuse must be capable of interrupting the maximum expected fault current.
4. **Coordination with Other Protective Devices**:
- The fuse should coordinate with other protective devices (e.g., relays, circuit breakers) to ensure selective tripping.
5. **Environmental Conditions**:
- Consider factors like temperature, altitude, and installation environment.
