Description
Technical field
The present invention relates to transfer switch electrical equipment, particularly a kind of automatic transfer switching electric appliance.
Background technology
Automatic transferring switch of power supply also claims " automatic transfer switching electric appliance ", be applicable to that requirements such as skyscraper, hospital, market, bank, fire-fighting, chemical industry, metallurgy provide the place of uninterrupted normal power supply, finish the power supply of double circuit power supply system (two-way civil power or one road civil power+generator) or three power supply system circuits (two-way civil power+generator) and change automatically, to guarantee the reliability of responsible consumer power supply.Along with growth in the living standard, people are more and more higher to the reliability requirement of power supply, and automatic transferring switch of power supply becomes the indispensable equipment of electric power system gradually.
Automatic transferring switch of power supply can be divided into PC level or two ranks of CB level.The PC level is can connect, carry but be not used in the automatic transferring switch of power supply of disjunction short circuit current.The CB level is the automatic transferring switch of power supply that is equipped with overcurrent trip, and the disjunction short circuit current can be connected and be used for to its main contact, generally possesses overload protection function simultaneously.PC level automatic transferring switch of power supply and CB level automatic transferring switch of power supply volume and cost, price are suitable.But PC level automatic transferring switch of power supply does not have short-circuit protection and overload protection function; so the distribution wire rood increases protection component (as circuit breaker or fuse); and general CB level automatic transferring switch of power supply itself possesses short-circuit protection and overload protection function; therefore distribution box (cabinet) volume of being made up of CB level automatic transferring switch of power supply is littler; cost is lower, and use amount is considerably beyond the PC level.
The main building block of CB level automatic transferring switch of power supply has: controller, operating mechanism and two circuit breakers.
The automatic transferring switch of power supply subminaturization is the technological development direction in current this field, and realize the automatic transferring switch of power supply miniaturization mainly capture the miniaturization that main points are operating mechanisms, present operating mechanism comprises electromagnetic type and single electric motor type, single motor double-acting power unit has " rotating disk-slide plate bidirectional operating mechanism " at present, " rotating disk-fork double-acting power unit " reaches " gear-slide plate bidirectional operating mechanism ", because rotating disk, fork, gear, parts such as slide plate are subjected to structural limitations, size is bigger, makes these single electric motor type operating mechanisms and electromagnetic type operating mechanism all can not realize subminaturization.
Summary of the invention
The objective of the invention is to design a kind of thin thickness, the small and exquisite automatic transfer switching electric appliance of volume.
In order to achieve the above object, the present invention is by the following technical solutions: a kind of automatic transfer switching electric appliance, comprise commonly used and back-up breaker and operating mechanism, it is characterized in that operating mechanism comprises motor output shaft, rotating disk, a left side, right axle shape driving lever, a left side, right rocking arm, position-limited wheel, support, support is connected between commonly used and the back-up breaker, position-limited wheel is coaxial with rotating disk, and be connected with motor output shaft, a left side, right axle shape driving lever is arranged symmetrically on the rotating disk, a left side, the fulcrum symmetry axis of right rocking arm is connected on the support, a left side, right axle shape driving lever respectively with a left side, right rocking arm one end is slidingly connected, a left side, the right rocking arm other end and a left side, irregularly-shaped hole on the right operating grip flanging is pegged graft, with position-limited wheel rocking arm end face in opposite directions be smooth arc, the cambered surface than long radius of it and position-limited wheel constitutes the rocking arm stopping means.
Because rocking arm and operating grip tie point are lower than the top of circuit breaker, the operating mechanism whole height is reduced; Its two, stopping means directly adopts rocker part, reduces number of spare parts, simultaneously, position-limited wheel is positioned in the middle of the rotating disk, takies little room, and rocking arm two ends and axle shape driving lever, operating grip employing socket connection mode, distance each other is very short, has reduced space hold.Therefore, adopt the technical program to make the attenuation of automatic transfer switching electric appliance thickness, smaller volume skilful, really realize the requirement of automatic change-over subminaturization.
