Description
Technical field
The present invention relates to a kind of surge protector, particularly the anti-misoperation apparatus of a kind of circuit breaker and surge protector tandem compound.
Background technology
Surge protector (Surge protection Device) is indispensable a kind of device in electronic equipment lightning protection, and used is called " lightning arrester " or " overvoltage protection device " English and is abbreviated as SPD.The effect of surge protector is that the instantaneous overvoltage of scurrying into power line, signal transmssion line is limited in the voltage range that equipment or system can bear, or powerful lightning current is let out to inflow place, protects protected equipment or system not to be hit and damages.The circuit in electric or electronic installation, components and parts are caused direct destruction by overvoltage.Surge protector (also claiming Surge Protector) is Suppressing Switching Overvoltage and back flashover, intrusion ripple, lightning induction and the instantaneous overvoltage that produces and the important protection device of the surge current of releasing.By its operation principle classification, SPD can be divided into voltage switch type and votage limit type, voltage-switch type SPD: in the time there is no instantaneous overvoltage, present high impedance, once response thunder and lightning instantaneous overvoltage, its impedance just sports Low ESR, allows lightning current to pass through, and is also referred to as " short switch type SPD "; Votage limit type SPD, in the time there is no instantaneous overvoltage, is high impedance, but with the increase of surge current and voltage, its impedance meeting constantly reduces, and its current-voltage characteristic, for strongly non-linear, is called as " pincers die mould SPD " sometimes.In order to prevent that switch-type surge protector is when the thunder and lightning impacting with high pressure; produce the follow-up continuous current of load power-frequency voltage; cause the power-off of distribution system entirety; the broken circuit protecting equipment therefore connect on switch-type surge protector; once thunderbolt power frequency continued flow occurs occurs, circuit breaker will move and make surge protector realize disjunction with power circuit fast, prevents that switch-type surge protector afterflow from causing the improper loss of power accident generation of user side.Voltage-limiting surge protector, most piezo-resistances that adopt, it is semiconductor type surge protector, belong to easy aging class thermal breakdown product, thunder and lightning and overvoltage can cause the progressively increase of its inner power frequency leakage current frequently, the final thermal breakdown phenomenon that occurs, there is above-mentioned fault for reducing voltage-limiting surge protector, although many products inside is provided with thermal cut-out tripping system, but due to the reason of discrepancies of each enterprise surge protector manufacturing process, can not be by only realizing aging heat dropout inspection, can only be according to GB2828 standard implementation industrial products check problem, the undetected surge protector of part still can occur over the ground or center line short circuit, occur that thermal breakdown fault causes user's power-off illegally accident.Occur in order to reduce similar phenomenon, the standard-required tripper of connecting on voltage-limiting surge protector, prevents from damaging the improper loss of power accident generation of the user side causing because of surge protector.
At present, the plug class surge protector extensively adopting in low-voltage distribution system, it is mainly made up of plug type protection module and pedestal, and protection module mainly comprises protection component, lug plate, housing and faulty indication mechanism.The tripper of connecting on above-mentioned two kinds of surge protectors; conventionally upper and lower the pedestal of circuit breaker and surge protector combined serial is installed; in the time changing surge protector; need to be by circuit breaker in off state; owing to there is no misoperation-proof mechanism; the situation that disassembling, assembling and replacing surge protector under circuit breaker conducting state easily occurs, now the end of incoming cables of surge protector is still charged, and electric shock accidents and load faulty easily occur.
