Description
Technical field
The invention belongs to fuse holder technical fields, more particularly to a kind of processing of the fusible link insulating base of energy-saving safe
Technique.
Background technology
With social progress, the reach of science, various household electrical appliance have become people's daily life must not
The component part that can lack.Dazzling household electrical appliance also give people while bringing people's great convenience and enjoying
Bring huge security risk.We on various media often it can be seen that because various household electrical appliance faces cause it is pernicious
Safety accident.
In daily life, each household residential electricity consumption is equipped with kilowatt-hour meter at home, and is also mounted with protectiveness
Fuse, and loaded onto in fuse the fuse by slicker solder or the making of lead-antimony alloy material, its purpose is to prevent
Wire short-circuiting or load increase cause electric current in circuit to increase, and ensure the safe handling of household electrical appliance and avoid the generation of fire.
To sum up, correct select and use fuse, it is the important ring for ensureing household appliances equipment safety and fire incident generation
Section.
Fuse is also referred to as fuse, it is defined as " fuse-link (fuse-link) " by IEC127 standards, and it is a kind of
Installation in circuit, ensures the electric elements of circuit safety operation.It is continuous along with electric current when circuit malfunctions or exception
It increases, and raised electric current is possible to certain important devices in damage circuit or valuable device, it is also possible to burn circuit
Fire even is caused, if correctly having disposed fuse in circuit, then, fuse will be increased to certain in current anomaly
When highly and certain, itself fusing cut-out electric current, to play the role of that circuit safety is protected to run.
Fuse holder be it is a kind of installation in circuit, ensure circuit safety operation electric elements.Work as circuit malfunctions
Or when abnormal, constantly increased along with electric current, and raised electric current is possible to certain important devices or expensive in damage circuit
Treasure part, it is also possible to burn circuit or even cause fire.If correctly having disposed fuse in circuit, then, fuse is just
Can current anomaly be increased to certain height and it is certain when, itself fusing cut-out electric current, to play protection circuit peace
The effect of row for the national games.
When fuse is powered, due to its own resistance, so that electric energy is converted into Joule heat makes melt generate heat, while electric current produces
Raw heat, to ambient radiation, heat is distributed by the modes such as convection current and conduction further through melt, shell.When fuse is logical
When crossing the operating current allowed, the heat of the heat and generation that distribute reaches balance, and heat will not accumulate in melt and make melt
Temperature increase, therefore fuse is not up to its fusing point and fuses.When fuse by electric current reach certain numerical value when,
The heat converted by electric energy increases, and radiating rate does not catch up with electrothermal calefactive rate, these heats will gradually accumulate on melt, makes to melt
Temperature increases, and when temperature reaches the fusing point of fuse, fuse starts to melt and continue to absorb heat and further melt to become liquid
State, subsequent fuse temperature further rise to evaporation point and form electric arc, and electric arc is a kind of gas ionization electric discharge phenomena, electric arc it is strong
Weak related with the voltage of circuit, voltage is higher, and electric arc is stronger, when the rated voltage main distinction of fuse is blown fuse
The circuit voltage that can be born is different, and fuse cannot be used in the circuit higher than its rated voltage, because circuit voltage is higher than guarantor
Electric arc is not easy to extinguish when dangerous silk rated voltage.In addition, electric arc it is strong and weak also with it is current related in circuit, the electric current the big then electric
Arc is stronger.If cut-out circuit cannot not be simply failed in time by arc extinction, it is also possible to other components in circuit are burnt, to
Lead to fire, causes the accident.High explosion-proof type fuse is to make arc extinction with the mode for installing explosion-proof sand additional, after arc extinction
Fuse just really cuts off electric current, achievees the purpose that protect miscellaneous equipment.
Diversification with electronic product development and newcooperative medical system, to circuit it is also proposed that many new protection requirements, thus can
Occur fuse kind many novel or with novel defencive function successively, such as express train acts, the resistance to pulse ability of extra-heavy,
Small rated current, bigger rated current is high voltage withstanding, special small size etc., it is special due to the continuous development of electronics industry
It is not the development of microelectronics and digital and electronic, many new projects, such as electrostatic protection is proposed to circuit protection, lightning strike protection,
The development of emi protection etc. minitype fuses also more requires micromation, and surface mount is unleaded, multi-functional or more
Circuit it is integrated etc., have partial insurance silk manufacturing enterprise be prepared for circuit protecting element of the exploitation with intelligent function or
Circuit protection module, to start new era of midget fuse update.
Currently, it is common to use fusible link insulating base insulation effect it is not notable, there are this some potential safety problemss, therefore
Urgent need wants a kind of simple in structure, significant fusible link insulated receptacle of insulation effect.
