Abstract
The utility model discloses a composite fuse which is a combined component having maximum allowable impact current energy I<2>t and a rated breaking capacity and formed by a current fuse and a recoverable fuse connected in series. The composite fuse is a novel protective component which combines advantages of a recoverable fuse and a general current fuse, has an impact current protection capability and/or a relatively high breaking capability, and has a protection function of the recoverable fuse in low fault current occasions.
Description
Technical field
The utility model relates to a kind of multi line insurance silk that recovers silk and the combination of electric current fuse, particularly a kind of novel fuse that recovers with impulse current defencive function and/or high breaking capacity.
Background technology
The existing fuse that recovers is semistor in essence, and it is that resistance value by ptc material plays the circuit protection effect to the positive correlation of temperature and the sudden change when the Curie point.Can recover fuse (polymer thermistor class) is to be made of institutes such as polymer and conducting particless, and after the special processing of process, conducting particles constitutes the chain conductive path in polymer.When circuit passes through running current, can recover fuse and be low resistive state, when having unusual overcurrent to pass through in the circuit, the heat that big electric current produces expands polymer rapidly, cuts off conducting particles, can recover fuse and be high-impedance state, after overcurrent in the circuit disappears, the polymer cooling, it is normal that volume recovers, wherein conducting particles constitutes conductive path again, and self-recovery is to initial condition.Owing to can recover the protection action of fuse and be a reaction to accumulation of heat; it needs the process of accumulation of heat; so just can reach the triggering temperature; so reaction speed is slow; for the impulse current that occurs; although electric current is very big,, give protection so can recover the fuse akinesia because the time of impulse current is instantaneous.
In addition, but can recover the fuse breaking current be not as big as the electric current fuse of metal bath, the occasion of major break down electric current may occur for some, it is inapplicable to recover fuse; The electric current fuse of metal bath can be designed to very fast quick type of reaction or special fast type fuse, it is then very difficult quick as the electric current fuse of metal bath to the reaction speed of big electric current to recover fuse, for the occasion of the element fast reaction protection that needs protection, it is also inapplicable to recover fuse; The electric current fuse of metal bath is promptly scrapped after fusing, and can not recover to realize having once more defencive function.Yet in more most occasion, can recover fuse and fuse electric current respectively has than the suitable applications scope, and this two series products still has a lot of difference, even may not substitute mutually.
Therefore be badly in need of a kind of disjunction protection and/or impulse current protection that both is fit to high fault current occasion, be fit to have the new-type element that can recover the fuse defencive function behind the low fault current occasion action protection again.
Summary of the invention
In view of this; technical problem to be solved in the utility model provides a kind of disjunction protection and/or impulse current protection that both is fit to high fault current occasion, is fit to have the novel complex protection element that can recover the fuse defencive function behind the low fault current occasion action protection again.
