Description
Technical field
The present invention relates to electric appliance insurance fields, and in particular to a kind of pressure-adjusting type fuse.
Background technique
Fuse is the protection equipment being widely used in appliance field, and the fuse of different parameters configuration can be used for electricity
The protection of power (forceful electric power) equipment and the protection of electronics (light current) equipment.Either any fuse, basic structure are all wrapped
It includes: pedestal, metal connecting piece, metal contact element, melt.Wherein, melt is the main working parts of entire fuse.Melt is
The one section of special conducting wire of series connection in circuit compares with other conducting wires in circuit, and melt portion has lesser section
Long-pending and poor dissipating-heat environment, when short circuit or overload occur for circuit, electric current increases, and the fever of melt position is noticeably greater than it
His conducting wire then makes take the lead in fusing, disjunction of melt to cut off circuit reach protection power train due to collection fuel factor
The purpose of other electrical equipments in system, circuit.
There are also the technical solutions about fuse in the prior art, one as disclosed in application number CN902248693
The reused Mercury fuse of patent, it is to connect two connecting terminals, mercury channel and gas by the mercury in mercury channel
Room communicates, gas chamber be sealing, and it is interior have mercury, occur overload or short circuit when, mercury expands rapidly disconnection, mercury channel
In mercury be ejected into gas chamber, power off, remove fuse after power-off, level shake it is several under, it is logical that mercury injects mercury
It can be reused behind road, the program cools down in time to mercury after cannot powering off, and allows mercury rapid desufflation, and mercury is easily caused to continue
The harm that expansion causes mercury to ooze out, service life is short, at the same not can guarantee it is horizontal shake mercury can completely into mercury channel,
A large amount of mercurys are easily accumulated in gas chamber, and fuse is caused to fail.
Summary of the invention
To make up the deficiencies in the prior art, solving fuse can not be reused, and the low problem of service life, the present invention mentions
This can be solved the problems, such as a kind of technical solution.
The technical solution adopted by the present invention to solve the technical problems is: a kind of pressure-adjusting type fuse, including left cover, absolutely
