(H) RW11-12 (F) outdoor high voltage AC drop fuse - an essential component in outdoor overhead distribution systems operating at a rated frequency of 50Hz and voltage of 10kV. This fuse acts as a safeguard for circuits or electrical equipment during overloads or short circuits. During standard operation, the fuse remains taut and secured within the power line. Should a fault occur, the resulting current surge prompts the fuse to blow, releasing the movable joint, causing the fuse tube to drop swiftly, thus interrupting the circuit. This mechanism ensures safety for line and equipment maintenance. The load type fuse incorporates elastic contacts and an arc extinguishing cover, enhancing its ability to manage load current in the power system.
The fuse adheres to rigorous technical standards, including GB/T 15166.3 - 2008 for high voltage AC fuses - Part 3: injection fuses, and DL/T 640 - 1997 for outdoor AC high voltage drop-tested fuses and fuse links ordering technical conditions.
