Description
Technical field
The utility model relates to the lightning protection varistor valve tripping mechanism of the lightning-protection module that is used for electrical equipment.
Background technology
Lightning-protection module is numerous, and its tripping mechanism is nothing more than two kinds; A kind of is mechanical type spring turnover panel indication tripping mechanism, and a kind of is electric indicating mechanism.Electricity indicating mechanism is a kind of circuit, and it can be with the glow color or the state of indicator light, or the sound comes the whether mechanism of deterioration of representation module.Mechanical type spring turnover panel indication tripping mechanism is that a cover utilizes eutectic welding tin and mechanical turnover panel " state indication mechanism ", the operating state that this little mechanism can be used as lightning-protection module on the one hand shows, window shows green during operate as normal, utilize short circuit current with the low temperature melts soldering tin during short circuit of lightning-protection module deterioration, the spring mechanical panel turnover mechanism is pulled away from varistor valve, make lightning-protection module break away from power supply, not explosion of lightning-protection module or not spontaneous combustion have been guaranteed, window shows redness simultaneously, tells the user that this lightning-protection module should have been changed.
At present, using maximum tripping mechanisms on the market is mechanical type spring turnover panel indication tripping mechanism.Promptly in a standard module width (18mm), concentrated an one or more varistor valve and a cover to utilize " the state indication mechanism " of eutectic welding tin and mechanical turnover panel.Owing to be subjected to the characteristic limitations of module width and piezo-resistance and for the needs of " state indication mechanism ", the disengaging direction of the low temperature bump on the varistor valve is parallel with the varistor valve plane.This mechanism mainly comprises a mesochite and a shell, in mesochite, be furnished with varistor valve, be furnished with the indicator board parallel with the in-plane of varistor valve between shell and mesochite, indicator board one end and extension spring are joined, and safety plate and indicator board join, when the varistor valve heating, button takes off a separation, under the effect of extension spring, and the indicator board rotation, color shown in the indicating window on shell changes, with the operating state of indication lightning-protection module; This dropout mode can satisfy instructions for use under normal situation.But make under plastic parts (mesochite) the distortion situation in valve block explosion or high temperature, because tripping mechanism dropout direction makes the plastic parts deformation direction vertical with valve block explosion or high temperature, produce mutually and interfere, the motion of tripping mechanism is stopped, or stopping of plastic parts or stopping of tripping mechanism itself.Tripping mechanism is motionless or be obstructed in motion process, and half situation about just stopping of moving takes place often.This thing happens is very dangerous.Because lightning-protection module does not break away from fully with circuit, the short circuit current that flows through valve block can make the varistor valve spontaneous combustion on fire.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of tripping mechanism and varistor valve not to produce interference each other to society, its dropout direction of motion is vertical substantially with the big plane of varistor valve, make tripping mechanism under worst situation, also can make the varistor valve breaking circuit safely smoothly reliably, guarantee the lightning protection varistor valve tripping mechanism that not spontaneous combustion of lightning-protection module is on fire to greatest extent.
The technical solution of the utility model is: design a kind of lightning protection varistor valve tripping mechanism, comprise base plate, indicator board, torsion spring and safety plate; Be provided with the circuit board that brings to few a slice varistor valve at described base plate upper bottom surface middle part, on the big plane of described varistor valve, the dropout solder joint arranged, described safety plate upper end and described dropout solder joint welding, safety plate lower end and circuit board side are affixed; On the base plate upper bottom surface, be furnished with paired axle bed with the big parallel plane at least one side of described varistor valve, on described axle bed, be connected with fixed axis, on fixed axis, be with indicator board and torsion spring, torsion spring one end and axle bed are affixed, and the other end passes behind the gap between safety plate and the varistor valve affixed with indicator board.
Be furnished with two tripping mechanisms on described base plate upper bottom surface, be furnished with three varistor valves on described circuit board, the safety plate of described two tripping mechanisms welds mutually with the big plane of two varistor valves of outermost respectively.
Be connected with at least one pair of pin at the base plate bottom surface, the input on the described circuit board is electrically connected with described pin.
On described base plate bottom surface, also be provided with the mistake proofing inserted link.
The problem that tripping mechanism of the present utility model solved is that the disengaging direction, valve block explosion direction and the mechanical turnover panel travel direction that make the low temperature bump are vertical with the varistor valve plane.The disengaging direction of low temperature bump, valve block explosion direction or high temperature make the plastic parts deformation direction consistent with the disengaging direction of tripping mechanism, avoided the limitation of movement of tripping mechanism fully, make tripping mechanism under worst situation, also can make the varistor valve breaking circuit safely smoothly reliably, guarantee that to greatest extent not spontaneous combustion of lightning-protection module is on fire.
