Description
Technical field
The present invention relates to a kind of electrical equipment technical field, particularly relate to a kind of cartridge fuse.
Background technology
Fuse refers to when electric current exceedes setting, and 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.
Metallic conductor is utilized to be series in circuit as melt, when transshipping or short circuit current passes through melt, fuse because of himself heating, thus a kind of electrical equipment of point deenergizing, fuse structure is simple, easy to use, be widely used in electric power system, as protection device in various electrical equipment and household electrical appliance, fuse is primarily of melt, shell and bearing 3 part composition, wherein melt is the key element controlling operating chacteristics, the material of melt, size and dimension determines operating chacteristics, melt material is divided into low melting point and high-melting-point two class, low melting material is as plumbous and lead alloy, the low easy fusing of its fusing point, because its resistivity is larger, therefore the sectional dimension making melt is larger, the metal vapors produced during fusing is more, be only applicable to the fuse of low breaking capacity, materials with high melting point is as copper, silver, its fusing point is high, be not easy fusing, but because its resistivity is lower, can be made into the sectional dimension less than low fusing point melt, the metal vapors produced during fusing is few, be applicable to the fuse of high breaking capacity, the shape of melt is divided into thread and banded two kinds, the shape changing variable cross-section significantly can change the operating chacteristics of fuse, fuse has various different operating chacteristics curve, go for the needs of dissimilar object of protection.
According to object of protection can be divided into protection transformer with and general electric equipment fuse, the fuse of protection voltage transformer, fuse, the fuse of protection semiconductor element, the fuse of protection motor of protection power capacitor and protect the fuse etc. of household electrical appliance; open type, semi-enclosed, tubular type and expulsion fuse can be divided into according to structure; current existing fuse structure is complicated; install inconvenient, cost is higher.
