Description
Technical field
The utility model relates to a kind of surge protector, particularly the surge protector state indicating device of a kind of pair of protection component.
Background technology
At present, in recent years, along with improving constantly of modernization level, the electronic message unit of installing in civil building and computer equipment are more and more, and electronic message unit general work voltage is lower, and withstand voltage level is also very low, very easily be subject to the harm of Lightning Electromagnetic Pulse, therefore be provided with the civil building of information system equipment, except considering, direct striking thunder prevention measure, also should to consider the safeguard procedures of Lightning Electromagnetic Pulse.The lightning surge overvoltage protection measure of Erecting and improving is the important component part of design in several serious fires.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 type of surge protector and structure are different by different purposes, but it at least should comprise a non-linear voltage limiting element.Basic components and parts for surge protector have: discharging gap, gas-discharge tube, piezo-resistance, twin zener dioder and choking-winding etc.
At present, the surge protector extensively adopting in low-voltage distribution system, mainly comprises protection component, lug plate, housing and faulty indication mechanism.On each protection component, have an independent disconnector, the operation principle of disconnector is that heat is threaded off, this function by the fusing of eutectic welding contact after disconnector Metallic rod utilize self elastic force to move to realize.After disconnector action, in the transparent window in surge protector front, will show red indication.Existing faulty indication mechanism mostly adopts spring element energy storage to realize faulty indication; no matter adopt stage clip or extension spring element; all first to make spring in energy storage state; when fault occurs; non-linear protection component (as piezo-resistance and twin zener dioder element) is thrown off with circuit; thereby make stage clip or extension spring no longer in tensioning state, under the effect of spring restoring force, drive faulty indication mechanism kinematic to realize faulty indication.Existing double-colored fault display device mechanism as disclosed in utility model patent ZL02243633.2, this mechanism, when breaking down, by being connected in the tension spring effect on lever, rotates lever, make the color in form show and change red display into by green, thereby realize faulty indication.But the stroke of the release unit of this faulty indication mechanism is very short, it is limited to depart from distance; particularly at the tin welding spot of protection component, meet after the fusing of surge fault; the tension spring being connected on lever not only will drive indicating device action; also will by the fuse link at lever middle part, drive tin welding spot to depart from disconnects circuit; in the situation that tension spring stroke is limited; probably cause pin not to be separated from completely; make mechanism sometimes can not cut off circuit completely; time one long electrical wave is crossed conference and is caused that burning even explodes, so reliability is not high.And this existing fault display device generally all stands on the wider side of surge protector, occupied area, space are larger.Especially when pressure-limiting function element is composed in parallel by two varistors, on every varistor, there is an independent disconnector, the operation principle of disconnector is that heat is threaded off, two disconnectors are all connected with lever by tension spring, if only have a slice action or a slice action to postpone, after disconnector action, lever still can not normal rotation, cannot make the color in form show and change red display into by green, can only be when two heaters lose efficacy simultaneously, lever ability normal rotation, color in form is shown and is changed into red display by green, so when monolithic varistor fault, cannot be quick, accurately, identify clearly.
