Background technology
Vacuum circuit-breaker mechanism conversion equipment is the changeover portion between circuit breaker operation mechanism and pole on the Cubicle Gas-Insulated Switchgear; As the mechanical connection between circuit breaker operation mechanism and pole, can increase the machine driving power of mechanism through mechanism's conversion equipment, and change the transmission direction of power; Improve mechanical advantage; Therefore, this quality with mechanism's conversion equipment design of transition transmission device function is with the mechanical property that directly influences vacuum circuit breaker operating mechanism.In the prior art, the general cover quadric chain that adopts of vacuum circuit-breaker mechanism conversion equipment, the vacuum circuit-breaker mechanism conversion equipment of this structure is not very remarkable to the effect of the machine driving power of increase mechanism, and is difficult to obtain higher mechanical advantage.
Summary of the invention
The utility model technical problem to be solved is, overcomes the weak point of prior art, provides a kind of and can strengthen mechanism's power output, improves the mechanism's conversion equipment that is used for the sulfur hexafluoride gas-insulating metal enclosed switchgear of mechanical advantage.
The technical scheme that the utility model is taked comprises base and bracing frame, and mechanism's conversion equipment is every to be composed in series by two cover quadric chains, promptly forms O by first connecting lever, long connecting rod and first short connecting rod that are installed on the base
1ABO
2The first cover quadric chain is connected connecting lever with second short connecting rod and second on being installed in bracing frame and forms O by being installed in first short connecting rod on the base
2BCO
3The second cover quadric chain is equipped with stop screw on support frame as described above.
Compared with prior art; The beneficial effect of the utility model is to have overcome a traditional cover quadric chain transmission to be difficult for obtaining the shortcoming than the great machinery interests; Adopt the form of two cover quadric chain tandem compounds, thereby increased mechanism's power output, mechanism is obtained than the great machinery interests easily; And reliable motion, the curve that acts on power and contact travel on the contact is reasonable.

Embodiment
Shown in accompanying drawing, the utility model mechanism conversion equipment is every to be composed in series by two cover quadric chains, promptly forms O by first connecting lever 2, long connecting rod 4 and first short connecting rod 5 that are installed on the base 3
1ABO
2The first cover quadric chain is connected connecting lever 7 with second short connecting rod 6 on being installed in bracing frame 8 with second and forms O by being installed in first short connecting rod 5 on the base 3
2BCO
3The second cover quadric chain is equipped with stop screw 9 on support frame as described above 8, pass through the dead point overshoot to prevent operating mechanism.
During use, the utility model is installed in through mounting seat 3 on the mounting flange 16 of switchgear, and first connecting lever 2 is connected with the circuit breaker operation mechanism 1 of switchgear; Second connecting lever 7 links to each other with connecting plate 11 through connecting pin 10; Connecting plate 11 again through guide finger 12 with about tune whole nut 13 and be connected with operation insulated tension pole 15, operating insulated tension pole 15 upper end mounting contact springs 14, when circuit breaker operation mechanism 1 combined floodgate; Operating mechanism 1 energy discharges the power that is produced and exports through first connecting lever 2; And connect short connecting rod 6 through long connecting rod 4, first short connecting rod 5 and second and pass to second connecting lever 7, circuit breaker operation mechanism 1 energy discharges power this moment of being produced through second connecting lever 8 and connect and pull 11 and change into vertical direction and act on touch spring 14, and passes to operation insulated tension pole 15; Thereby act on the arc control device moving contact; Make the arc control device motion of realize closing a floodgate, when the arc control device dynamic/static contact rigidly connects when touching, the reaction force that mechanism driving power will overcome touch spring 14 forms the overtravel of contact 4mm; When mechanism's power output is delivered to the B application point; Because the radius of turn of first connecting lever 2 greater than length between 5 liang of pin joints of first short connecting rod, realizes amplifying the first time of transmission power, when power is delivered to O through interface point B point
4During pin joint; Realize amplifying the second time of transmission power, when first short connecting rod was connected with second that angle is 170o between short connecting rod 6 connecting rods, moving contact reached firm chalaza; Actuating force increases rapidly to overcome the reaction force of touch spring 14; When first short connecting rod 5 and second connect that angle is 175o between short connecting rod 6 connecting rods, power output was maximum, can increase to 18000N.
Fig. 2 is for to act on power and contact travel curve chart on the contact through the mechanism that the utility model calculated.The curve IV is total actuating force, and the curve I is total resistance, and it is to be formed by stacking tripping spring power III and touch spring power II, and V is the firm chalaza of contact, and VI 6 is a contact combined floodgate terminating point.Through Fig. 2 can find out the total actuating force of curve IV on ordinate all the time greater than the total resistance of curve I, can satisfy of the requirement of arc control device divide-shut brake characteristic fully to mechanically actuated operation power.
