High voltage fuse for interrupting a wide range of currents and especially suited for low current interruption |
摘要 |
A high voltage fuse for interrupting a wide range of currents and especially suited for low current interruption is disclosed. The fuse is comprised of a fuse element having a first and a second plurality of portions of reduced cross-sections. The second plurality of portions further comprise two or more parallel conducting paths some of which carry a portion of material which has a lower melting temperature than the melting temperature of the material of the fuse element. The parameters of the first and second plurality of reduced cross-section portions, the lower melting point material, and the fuse element itself are selected to adapt the fuse to provide proper protection for the various current conditions to which a high voltage transformer is subjected. The fuse element provides fast rupturing under short-circuit current conditions while also providing the characteristic of withstanding relatively high inrush current conditions. The fuse element further provides improved low current clearing ability for the fuse, and a fuse which responds quickly to through fault (secondary fault) conditions in a transformer.
