Description
Technical field
The present invention relates to a kind of surge bleeder, be specifically related to a kind of surge bleeder that can effectively promote electronic equipment safety in utilization.
Background technology
At present, along with the high development of various microelectric techniques, the design of electronic equipment is more and more accurate, therefore, for making these electronic equipment energy normal operations, and the surging of its circuit of avoiding flowing through causes these electronic equipments to damage, and is that relevant dealer endeavours one of important topic of research and development always.
Generally, surging also can be described as high voltage (stream) pulse, according to its source, can divide into the surging of the outside surging producing of circuit and inside circuit generation, wherein, the outside surging producing of circuit is because around thundering at circuit mostly, or due to circuit is directly struck by lightning, be therefore called again thunder surging (1ightning surge); The surging that inside circuit produces, is that electronic switch switches the surging of supervening in action in circuit mostly, is therefore called again and switches surging (switching surge).
As previously mentioned, if be provided with the control assemblys such as relay (relay), electronic switch (switch) or magnetic plug (solenoid) in electronic equipment, in the process of electronic equipment running, these control assemblys will certainly carry out a large amount of closing and the switching action of conducting state, therefore be easy to produce a large amount of surgings, and then the circuit of electronic equipment is exerted an influence, and cause electronic equipment misoperation.For solving foregoing problems; traditionally; the manufacturer of associated electronic device can arrange a surge bleeder in the supply line of these electronic equipments; so that can be when surging produces; by this surge bleeder, form a discharge path; surging is directed to an earth terminal of circuit, and then can protects electronic equipment can not suffer damage because of surging.
Traditionally, metal oxide piezo-resistance (Metal Oxide Varistor is called for short MOV) is a kind of for making the dielectric material of surge bleeder.Modal MOV is the poly semiconductor ceramic component being formed by Zinc oxide particles and a small amount of other metal oxide or polymer mixed sintering, inner at these MOV, the intersection of other oxide of Zinc oxide particles and contiguous Zinc oxide particles, can form grain boundary layer and diode effect occurs.Owing to including huge amount and mixed and disorderly Zinc oxide particles in MOV, therefore, whole MOV is equivalent to a large amount of aggregates of connected diode dorsad.Under the state of low-voltage, only there is the small converse electrical leakage electric current of small part can pass through MOV, yet, when running into high voltage, can there is punch-through effect (punch-through effect), make high-tension large electric current can pass through MOV.Why MOV is widely used in the dielectric material of making surge bleeder, and because it has when low-voltage, resistance is high, the low nonlinear current-voltage curve of resistance during high voltage.
Although, utilize the nonlinear current-voltage producing between Zinc oxide particles grain boundary layer, MOV is applied to make surge bleeder, really can reach the object that surging is released.Yet, after the studying for a long period of time and observe of inventor, find that traditional surge bleeder still exists many improved defects for the treatment of in design.First, owing to being the annexation that is " line contacts " between the wire of traditional surge bleeder and MOV, therefore, and under limited affixed area, the mutual fixing position between MOV and wire, voltage and electric current that unit are will be born are high, very easily burst apart; Moreover, because voltage and electric current that the unit are of MOV will be born are high, stronger instantaneous overvoltage may make during by MOV to produce perforation on resistive element, causes larger electric current moment pass through and produces high heat and on fire, generation what is called " instantaneous overvoltage destruction "; In addition, result of study shows, when MOV is subject to heavy current impact many times, even if do not occur moment burst apart or directly on fire, too high temperature also can be accelerated MOV ageing process, make MOV that low-resistance linearisation phenomenon progressively occur, and produce some weak spots, make the pernicious increase of leakage current and concentrate to flow into weak spot, weak spot material is melted and forms short circuit hole, now, if there is again larger electric current to pour into short dot, can produce high hot and on fire.
Hence one can see that, the design of tradition surge bleeder is after relatively high-tension electric current (as: switching surging) Multiple through then out, or after greatly the electric current (as: thunder surging) of voltage passes through, all may make wire or MOV sheet cause expendable damage.Therefore, MOV itself not only can quick aging in the process of using, and the mutual fixing position between MOV and wire also may burst apart, and the defunctionalization that surging is released.
For ordinary consumer, for more accurate, valuable electronic equipment, consumer more can focus on its surge prevention function, to avoid impaired because of these electronic equipments, and consumer is brought to greatest loss.According to investigations, most consumers all think, the surge bleeder that is arranged at electronic equipment can provide complete protection to electronic equipment.Yet, because traditional surge bleeder has aforesaid many defects, so that overvoltage protection cannot be provided for a long time constantly.Therefore, when MOV is aging or MOV and wire between mutual fixing position while bursting apart, traditional surge bleeder just can be lost the effect that its surging is released, so, when supply line produces aforementioned surging again, just can cause precision and valuable electronic equipment to be badly damaged, cause the heavy losses on property; In addition,, due to the design of traditional surge bleeder, the impact that cannot avoid high heat to produce MOV, still may cause MOV Yin Gaore and catching fire, the danger that therefore may bring initiation fire.
In sum; how to design a kind of surge bleeder; surge bleeder possessed can repeatedly release the characteristic of surging; to avoid traditional surge bleeder burst apart or burn and lose the effect that its surging is released because of MOV; cause claimed electronic equipment to damage; even because of MOV, burn the problems such as initiation fire, become an important topic of desiring most ardently discussion.
