Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.
The utility model be it is a kind of Electric Appliance Cabinet, drawout cubicle, electric box peripheral operation breaker of plastic casing mechanical chain machine
Structure, it relies on the mechanical rotation switching mechanism of cam and swing rod, using operation handle rotation process outside general cabinet, realizes two
The mechanical chain of breaker of plastic casing.Circuit-breaker status can be carried out by operation handle outside cabinet to lock or unlock, and can also be realized double
Power supply is manually converted.
Referring to Fig. 1 and Fig. 2, the utility model includes mainly pedestal 11, cam 12, bearing block 8, cam drive mechanism and two
A breaker operator unit, wherein cam drive mechanism includes mainly the outer operation handle 2 of cabinet and square steel 3, each breaker operator
Unit includes mainly pulley 6, driving lever 9, swing rod 13, sliding rail 14, sliding block 15 and travel switch 16.
It will need to realize the left end and right end that two chain breaker of plastic casing are separately fixed at pedestal 11, by general
The rotation process of operation handle 2 outside cabinet, makes cam 12 rotate, and cam 12 drives the swing rod 13 of two breaker operator units, slides
Block 15 sequentially moves in the opposite direction respectively, realizes the conversion operation of two breakers.
When two breaker switching motions, it is necessary to assure breaker elder generation reliable separation (the separating brake) (attached drawing to have closed a floodgate
3), another breaker just allows to combine (combined floodgate) (attached drawing 4), and vice versa.Therefore it is arranged on cam 12 upper and lower two big
Small different protrusion, for the protrusion of upside for closing a floodgate, corresponding central angle is smaller；The protrusion of downside is used for separating brake, corresponding
Central angle it is larger.This ensures that when cam 12 rotates, the protrusion of downside, which initially strikes, needs separating brake breaker side
Swing rod 13 on pulley 6, and encounter the pulley 6 on the swing rod 13 for needing combined floodgate breaker side after the protrusion of upside, avoid
Cause two breaker paired runnings.
It is respectively arranged with passive travel switch 16 on the outside of the left and right sliding block of the present apparatus, convenient for showing the chain work shape of breaker outside cabinet
State.
Since operation handle carries locking device 1 outside general cabinet, it is only necessary to install lockset, that is, lockable additional in corresponding position.
In addition, since the present apparatus is identical as dual-power transfer switch operating principle, it is also used as easy electricity double manually
Supply changeover device realizes that dual power supply is manually converted.
The present apparatus has the characteristics that：Simple in structure, easy for installation, of low cost, reliable in action can adapt to various types
Number breaker of plastic casing.
Breaker of plastic casing interlocking gear is operated outside this cabinet is suitable for rated current 800A hereinafter, exchange 50HZ, nominal operation
Voltage 440V each serial power distribution cabinets below, drawout cubicle, electric box are, it can be achieved that mechanical chain protection, prevents maloperation.
