High Voltage Fuses 23kv
Bay-O-Net Tap Changer Switch Fuse for Oil Transformer Prnt4-15.5/25
Product Description
PRNT4-15.5, PRNT4-24, PRNT4-40.5 series of high-voltage fuses for overload protection of oil-immersed transformers are suitable for use in power systems with AC rated frequency of 50Hz and rated voltage of 15.5kV, 24kV and 40.5 kV respectively. As the overload protection protection element for power transformer and other power equipment, the fuse is installed in the transformer oil of American type box transformer or other box transformer, and can be co-boxed with transformer and load switch. The oil-immersed transformer overload protection high-voltage fuse can not be used alone, can be connected in series with the transformer backup protection high-voltage current-limiting fuse to form a full range of high-voltage current-limiting fuse. When the overload current exceeds the specified value for a certain period of time, the circuit is opened by the overload high-voltage fuse. When the short-circuit current passes through the fuse, the short-circuit current is opened by the backup high-voltage current-limiting fuse. The product can be widely used in the distribution protection of wind power generation, solar power generation, tide stream power generation and other equipment.
This product consists of two parts: overload protection fuse and plug-in bracket.
