Product Description:
The High Voltage Fuse Cutout, often referred to as a Drop-out Fuse, plays a crucial role in overcurrent protection for outdoor medium-voltage distribution systems. These systems generally operate within the voltage range of 11kV to 38kV.
This device integrates a fuse link with a hinged holder mechanism. When a fault occurs, it automatically disconnects the electrical circuit by "dropping out" in a visible manner. This feature not only indicates the presence of a fault but also enhances safety by isolating the faulty section.
In addition to its automatic protection capabilities, the Drop-out Fuse functions as a manual isolating switch. This allows technicians to safely perform maintenance work on the network without risking exposure to live components.
Built to withstand various environmental conditions, the robust design of the High Voltage Fuse Cutout ensures dependable operation in different weather scenarios. Due to these qualities, it has become a widely accepted standard for safeguarding transformers and distribution lines in outdoor medium-voltage networks.
Features:
This device serves a dual purpose by functioning both as an automatic overcurrent protector and as a visible isolation point for manual switching. This combination effectively reduces the overall equipment costs by integrating two essential roles into a single unit.
When a fault occurs, the fused tube physically drops down, offering an immediate and unmistakable visual indication of the fault location. This feature greatly facilitates quick identification and repair, minimizing downtime.
The device employs an expulsion-type arc extinguishing mechanism. Gas produced by the liner rapidly quenches the electrical arc, ensuring safe and effective interruption of fault currents to protect the system.
Available with high-grade porcelain or hydrophobic polymer housings, this product offers outstanding resistance against ultraviolet radiation, pollution, and moisture. Its robust weatherproof construction ensures reliable performance in harsh environmental conditions.
Technical Parameters:
The rated voltage for this equipment varies depending on the system and includes options such as 12kV, 15kV, 24kV, 27kV, and 38kV. This flexibility allows it to be compatible with a wide range of electrical networks.
When it comes to the rated current, the holders are designed to handle 100A, 200A, and 400A. Additionally, the fuse links available cover a range from 1A to 140A, providing extensive protection options for different applications.
The device offers impressive breaking capacities, including 6.3kA, 8kA, 10kA, and 12.5kA, all measured as symmetrical RMS values. This ensures reliable interruption of high fault currents under various conditions.
Compliance with international standards is guaranteed, as the product meets IEC 60282-2, IEEE C37.41, and ANSI C37.42 specifications. This adherence ensures safety, performance, and interoperability in diverse environments.
For insulation, the equipment uses high-strength porcelain or silicone rubber polymer materials. These choices contribute to durability and long-term reliability, especially under mechanical and environmental stresses.
Finally, the operational temperature range spans from -40°C to +55°C. It is also suitable for use in areas with heavy pollution, classified under pollution classes C, D, and E, making it well-suited for harsh outdoor conditions.
Applications:
This device is mainly installed on overhead distribution lines to provide protection for branch circuits and to minimize the areas affected by faults. Its primary role is to ensure that any electrical faults do not spread beyond the immediate vicinity, thereby maintaining system stability and safety.
It serves as the standard protective equipment for both pole-mounted and pad-mounted transformers. By doing so, it effectively shields these transformers from damage caused by overloads and short circuits, ensuring their longevity and reliable operation.
Moreover, this protection device is commonly utilized in renewable energy collection systems, including solar farms and wind turbines. It also finds extensive application in industrial power supply networks, where dependable and cost-efficient high-voltage protection is crucial for uninterrupted power delivery.
