Description
Technical field
The utility model relates to a kind of running-in machine of control mechanism of vacuum circuit breaker.
Background technology
AC high voltage vacuum breaker need to carry out repeatedly mechanical endurance test to mechanism's practical operation situation in the product design and development stage, verifies with this whether design satisfies technical requirement.
Existing AC high voltage vacuum breaker must assemble a whole set of complete product in the product development design phase and carry out mechanical endurance test, namely assembles complete vacuum circuit breaker mechanical driving part and major loop part.Vacuum circuit breaker major loop departmental cost proportion in whole cost of products is high, and mechanical endurance test is a kind of destructive test, due to the actual needs checking is the reliability of mechanical driving part, as carry out test of many times and will bring very large experimentation cost, cause cost greatly to increase, simultaneously, final assembly is carried out mechanical running-in test and also can be caused the efficiency of loading and unloading low, increases operating personnel's labour intensity.Reduce work efficiency.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of running-in machine of control mechanism of vacuum circuit breaker for problems of the prior art, its objective is effective analog mechanical durability test, increases work efficiency when reducing experimentation cost.
The technical solution of the utility model is that this kind running-in machine of control mechanism of vacuum circuit breaker comprises axle, and an end of described axle is connected with connecting lever by connecting pin; The other end of described axle is equipped with cover plate, the second spring is installed on the axle between cover plate and connecting pin, and the two ends of the second spring is fixed by end cap; An end near cover plate on described axle is equipped with the first spring, and the end of the first spring is equipped with the guiding pad and fixes by nut.
Described cover plate is fixed on the high-pressure vacuum breaker framework by support bar and screw rod, and the support bar that is positioned at the high-pressure vacuum breaker base of frame is fixed by nut.
Described connecting lever is fixedly mounted on the high-pressure vacuum breaker framework by pin.
This kind running-in machine of control mechanism of vacuum circuit breaker with said structure has the following advantages:
1. this kind running-in machine of control mechanism of vacuum circuit breaker by the analog mechanical durability test, has been avoided the repeatedly destruction of vacuum circuit breaker major loop part, has improved work efficiency when having reduced production cost.

3. this kind running-in machine of control mechanism of vacuum circuit breaker is simple in structure, effect is excellent, has good application and popularization value.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is that the utility model is arranged on the structural representation on the high-pressure vacuum breaker framework.
In Fig. 1,1: the high-pressure vacuum breaker framework; 2: cover plate; 3: the guiding backing plate; 4: the first springs; 5: end cap; 6: screw rod; 7: axle; 8: the second springs; 9: support bar; 10: connecting pin; 11: connecting lever; 12: pin.
Embodiment
By structure combination shown in Figure 1 as can be known, this kind running-in machine of control mechanism of vacuum circuit breaker comprises axle 7, and an end of axle 7 is connected with connecting lever 11 by connecting pin 10; The other end of axle 7 is equipped with cover plate 2, and the second spring 8 is installed on the axle 7 between cover plate 2 and connecting pin 10, and the two ends of the second spring 8 are fixing by end cap 5; An end near cover plate 2 on axle 7 is equipped with the first spring 4, and the end of the first spring 4 is equipped with guiding pad 3 and fixes by nut.
Cover plate 2 is fixed on high-pressure vacuum breaker framework 1 by support bar 9 and screw rod 6, and the support bar 9 that is positioned at high-pressure vacuum breaker framework 1 bottom is fixed by nut.Connecting lever 11 is fixedly mounted on high-pressure vacuum breaker framework 1 by pin 12.
The specific works principle of this kind running-in machine of control mechanism of vacuum circuit breaker is: the contact closing force in the first spring 4 simulation major loops, moving contact in axle 7 simulation major loops, isolating switch drives connecting lever 11 and rotates around pin 12 when motion, during combined floodgate, connecting lever 11 clockwise rotates, band moving axis 7 moves upward, this moment, the second spring 8 was just compressed by end cap 5, when connecting lever 11 turns to closing position, the second spring 8 that is enclosed within on axle 7 also stops compression, connecting lever 11 is buckled in closing position by lock for circuit breaker simultaneously, completes closing operation; When isolating switch carries out sub-switching operation, the energy of the second spring 8 compressions just is released, and is with fast moving axis 7 to move downward, and drives simultaneously connecting lever 11 and rotates counterclockwise around pin 12, remained on open position by isolating switch when isolating switch moves to open position, complete sub-switching operation.
This kind running-in machine of control mechanism of vacuum circuit breaker has been avoided the repeatedly destruction of vacuum circuit breaker major loop part by the analog mechanical durability test, has improved work efficiency when having reduced production cost.And, avoided the assembling to a whole set of complete product when carrying out mechanical running-in test, reduced operating personnel's labour intensity when improving the efficiency of loading and unloading.
