Abstract
The utility model discloses a current limiting fuse, the current limiting fuse outside is provided with the safety cover, and can solve the fuse encapsulation and break and lead to on every side the device to receive the problem of arcing material influence, safety cover one end is provided with uncaps, uncap and be connected with the safety cover through connecting to detain, can guarantee heat dispersion in the protection, being provided with strong insulating sealing -in between shell and the ceramic package, can strengthening current limiting fuse's insulating properties, this current limiting fuse has the advantage that insulating properties is good, has wide market prospect.
Description
Technical field
The utility model relates to electric automatization field, is specifically related to a kind of current limiting fuse.
Background technology
Fuse refers to when electric current exceedes setting, with the heat that itself produces, melt is fused, a kind of electrical equipment of open circuit.Fuse is after exceeding setting a period of time according to electric current, makes Melt molten, thus circuit is disconnected with the heat that himself produces; Use a kind of current protector that this principle is made.Fuse is widely used in high and low voltage electric distribution system and control system and power consumption equipment, as the protector of short circuit and overcurrent, is apply one of the most general protection device.Current fuse also exists fuse encapsulation and breaks and cause peripheral devices to be affected and the problem of insulation property difference.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of current limiting fuse, to solve the above-mentioned multinomial defect caused in prior art.
For achieving the above object, the utility model provides following technical scheme: a kind of current limiting fuse, comprise vacuum fusing structure and current limliting fusing structure, described vacuum fusing structure comprises copper melts, conducting rod and shell, described copper melts is fixing in the enclosure, described copper melts arranged outside has radome, described conducting rod is arranged on copper melts both sides, described current limliting fusing structure comprises ceramic package, silver melt and glass insulation rod, described glass insulation rod is fixed in ceramic package, described silver-colored melt is plated on glass insulation rod, quartz sand is provided with between described glass insulation rod and ceramic package, connected by the connecting rod be arranged between conducting rod and glass insulation rod between described vacuum fusing structure and current limliting fusing structure.
Preferably, described current limiting fuse arranged outside has protective cover, and the material of described protective cover is crystallized glass ceramic material.
Preferably, described protective cover one end is provided with uncaps, described in uncap and to be connected with protective cover by linking fastener.
Preferably, strong insulation cushion is provided with between described shell and ceramic package.
The beneficial effect of above technical scheme is adopted to be: a kind of current limiting fuse of the utility model structure, described current limiting fuse arranged outside has protective cover, fuse can be solved and encapsulate the problem causing peripheral devices to be subject to arcing Effect of Materials of breaking, described protective cover one end is provided with uncaps, described uncapping is connected with protective cover by linking fastener, heat dispersion can be ensured while protection, sealing-in of insulating by force is provided with between described shell and ceramic package, the insulation property of current limiting fuse can be strengthened, this current limiting fuse has the advantage of good insulation preformance, there are wide market prospects.
