Product Description:
The High Voltage Fuse Cutout, often referred to as a Drop-out Fuse, plays a crucial role in safeguarding outdoor medium-voltage distribution systems, generally ranging between 11kV and 38kV. This device is specifically engineered to provide overcurrent protection, ensuring the stability and safety of electrical networks.
It features a combination of a fuse link and a hinged holder mechanism. When a fault occurs, the fuse link melts, causing the holder to "drop out" visibly. This action automatically interrupts the circuit, preventing further damage. Additionally, it can function as a manual isolating switch, allowing technicians to safely disconnect the circuit for maintenance purposes.
Designed to withstand various environmental challenges, the High Voltage Fuse Cutout is built with durability in mind. Its robust construction guarantees consistent performance even under harsh weather conditions. Because of these qualities, it is widely adopted as a reliable solution for protecting transformers and distribution lines in medium-voltage networks.
Features:
The device offers dual functionality, serving both as an automatic overcurrent protector and as a visible isolation point for manual switching. This combination helps in significantly reducing the overall equipment costs associated with electrical installations.
One of its key features is the visible fault indication. When a fault occurs, the fused tube physically drops down, providing an immediate and clear visual cue. This allows maintenance personnel to quickly identify the fault location and carry out repairs efficiently.
The product also boasts superior arc extinguishing capabilities. It employs an expulsion-type mechanism where the gas produced by the liner rapidly quenches the electric arc. This ensures a safe and reliable interruption of fault currents, minimizing potential damage.
Designed to withstand harsh environmental conditions, the device is available in housings made from high-grade porcelain or hydrophobic polymer. Both materials provide excellent resistance against UV radiation, pollution, and moisture, enhancing durability and performance.
Application Areas
Technical Parameters:
The device operates at a rated voltage that varies depending on the system, including options such as 12kV, 15kV, 24kV, 27kV, and 38kV. This flexibility allows it to be suitable for a wide range of electrical systems and applications.
It supports rated currents of 100A, 200A, and 400A at the holder, with fuse links available ranging from 1A up to 140A. This variety ensures compatibility with different current requirements and protection needs.
The breaking capacity of the device is designed to handle symmetrical RMS currents of 6.3kA, 8kA, 10kA, and 12.5kA. This range provides reliable interruption capabilities for various fault conditions, enhancing system safety.
Compliance with international standards is maintained, including IEC 60282-2, IEEE C37.41, and ANSI C37.42, which guarantees quality and performance according to globally recognized benchmarks.
Insulation is provided by materials such as high-strength porcelain or silicone rubber polymer, offering excellent durability and resistance to environmental stresses.
The device can operate within a temperature range from -40°C to +55°C, making it suitable for use in heavy pollution zones classified as Class C, D, or E. This wide operating range ensures reliable performance in harsh outdoor conditions.
Applications:
These devices are mainly installed on overhead distribution lines with the purpose of protecting branch circuits. They play a crucial role in limiting the impact zones of electrical faults, ensuring that disturbances do not spread excessively across the network.
Serving as the standard protective equipment for both pole-mounted and pad-mounted transformers, these devices safeguard the transformers from potential overloads and short circuits. This protection helps to maintain the reliability and longevity of the transformers in various electrical distribution settings.
Furthermore, they have found extensive application in renewable energy collection systems, including solar farms and wind turbine installations. In addition, these protective devices are commonly used in industrial power supply networks where there is a need for dependable and cost-effective high-voltage protection solutions.
