Abstract
The utility model relates to a switching device of an electrical appliance, especially a double-power switch. A switching mechanism comprises levers and a turntable, wherein each of the switches of a standby power circuit breaker and a common power circuit breaker is provided with a lever groove matching the lever; two levers are symmetrically disposed on two sides of the turntable and are corresponding to the standby power circuit breaker and the common power circuit breaker respectively; each lever is fixed in a double-throw switch through a rotation shaft, one end of the lever being inserted into the lever groove and the other end of the lever being linked with the turntable. According to the above structure, connection poles on the turntable rotate as the turntable rotates, and drive the lever to rotate around the rotation shaft, so that switching on and switching off of corresponding circuit breaker switches are conducted; and U-shaped link sheets of the levers, through the moment transformation, can guarantee enough force to perform the switching movement. Because collision does not exist in the linkage of such a structure, the switching is stable, and the levers and the turntable are in close cooperation, the two circuit breakers cannot be switched on at the same time, mechanical interlock is truly realized, the double-power switch is reasonable in structure, and the service life of the switching mechanism is prolonged.
Description
Technical field
The utility model relates to a kind of electrical apparatus-switching device, especially a kind of twin-power switch.
Background technology
Twin-power switch (abbreviation duplicate supply) is mainly to adopt breaker of plastic casing (CB level) or isolating switch (PC level) element to form.According to the regulation of standard GB/T/T14048.11-2008, be divided into CB level, PC level and CC level.As executive component, be equipped with single-chip microcomputer and be the automatic controller of core and with the controlling organization of electromechanical interlock, be a kind of perfect performance, the twin-power switch that safe and reliable, automaticity is high, the scope of application is wide.Product is applicable to exchange 50/60Hz, 690V and following, rated current is in the electric power system of 6A to 1250A and following two-way power supply (conventional power supply N and stand-by power supply or generator power supply R), Yin Yi road power supply breaks down (have a power failure, under-voltage, overvoltage, disconnected phase, frequency shift (FS)) and carries out the automatic switchover between power supply, to guarantee reliability and the fail safe of power supply.Be widely used in skyscraper, community, hospital, airport, harbour, fire-fighting, metallurgy, chemical industry, weaving etc. and do not allow the important place having a power failure, realize unattended operation and power continuously.
But the switching mechanism wherein of twin-power switch in the market, in prior art, is to adopt a disk, disk both sides arrange two draw-in grooves, then the switch of circuit breaker is all connected with a cross bar, then draw-in groove is stretched in one end, by the rotation of disk, carry out the switch of switching right and left both sides circuit breaker, because draw-in groove easily and between cross bar exists gap, in the time of switching, easily collide, unstable, structure is also unreasonable, can cause the switching mechanism lost of life.
Summary of the invention
The purpose of this utility model is, provide a kind of rational in infrastructure, switch twin-power switch stable, long service life.
The utility model solves the technical scheme that its technical problem adopts: a kind of twin-power switch, comprise auxiliaries-supply circuit-breaker, conventional power circuit breaker, base plate, double-throw switch, housing, auxiliaries-supply circuit-breaker and conventional power circuit breaker are arranged in housing, double-throw switch is arranged on housing, base plate is fixed on housing side, described double-throw switch comprises switching mechanism, switching mechanism comprises lever, rotating disk, at auxiliaries-supply circuit-breaker, on the switch of conventional power circuit breaker, be equipped with a lever slot with lever adaptation, rotating disk bilateral symmetry arranges two levers, corresponding with auxiliaries-supply circuit-breaker and conventional power circuit breaker respectively, lever is fixed in double-throw switch by a rotating shaft, insert in lever slot one end, the other end and rotating disk are connected.
Of the present utility modelly further be set to: described switch is a U-shaped double-action plate, a U-shaped double-action plate side corresponding with lever be provided with one with the connecting hole of lever adaptation as lever slot.
Of the present utility modelly further be set to: described lever is different in nature lever, side projection one connecting rod that lever is corresponding with switch, the opposite side of lever is a U-shaped opening, described rotating disk comprises upper cover and lower cover, upper cover is fixed to one another and is connected by joint pin with lower cover, between upper cover and lower cover, be provided with two symmetrical joint pins, U-shaped open card forms being connected of lever and rotating disk on joint pin.
Joint pin on said structure turntable is along with dial rotation, and activation lever is rotated around rotating shaft, with this, drives corresponding killer switch to switch each other folding, the U-shaped double-action plate of lever, can convert by moment, guarantee that enough power switches action, because this structure interlock does not exist collision, stable during switching, lever and rotating disk closely cooperate, and both sides circuit breaker can not be closed a floodgate simultaneously, really play mechanical chain, rational in infrastructure, extended useful life of switching mechanism.
