Description
Technical Field
The utility model relates to a high-voltage fuse belongs to high-voltage fuse equipment technical field.
Background
Fuses are the simplest protective electrical devices that are used to protect electrical equipment from overload and short circuit currents; selecting different types of high-voltage fuses such as outdoor drop-out type and indoor type according to installation conditions and purposes, and selecting special series for the high-voltage fuses of special equipment; fuses are often said to be of the fuse type. The PT high-voltage fuse of transformer substation plays important guard action to PT and whole transformer system safety, in the daily operation work, often because of ferromagnetic resonance, single-phase ground connection and intermittent arc ground connection take place for the system, PT is inside to have single-phase ground connection or alternate short circuit fault, secondary circuit short circuit and secondary side fuse not fusing etc. cause PT high-voltage fuse to melt, generally be high-voltage fuse fusing, if the fuse fails to obtain in time correct, quick change, will make protection, measurement etc. lose voltage, lead to the loss that can't estimate. Some existing high-voltage fuses are complicated to replace and slow in speed; some are not fixed firmly and fall off easily.
