Production efficiency is relatively low.
Utility model content
The technical problems to be solved in the utility model is to provide one kind and is simple to manufacture, a high major loop of efficiency of assembling
Vacuum circuit breaker.
To achieve these goals, the technical scheme that this utility model is taken is：
The vacuum circuit breaker of a described major loop include insulating cylinder, the vacuum interrupter being located in the insulating cylinder,
Insulated tension pole, contact arm and Mume flower contact, are provided with the inner fixed stand of molding in conjunction, the vacuum interrupter in the insulating cylinder
Lower end is connected through the centre bore of the inner fixed stand with the insulated tension pole, is provided with and vacuum interrupter in the insulating cylinder
The upper bracket that upper end is fixedly connected；It is provided with the insulating cylinder respectively positioned at the upper of the vacuum interrupter upper and lower end position
Wire outlet seat and lower wire outlet seat, the upper wire outlet seat and the lower wire outlet seat are provided with the contact arm, and the Mume flower contact is arranged on
The contact arm external part, the lower wire outlet seat be connected with the vacuum interrupter lower end by being flexible coupling.
The insulated tension pole connection end is fixed in the insulated tension pole and described true through the end being flexible coupling
Between empty arc-chutes lower end.
The upper wire outlet seat is fixedly connected with the side of the upper bracket by screw.
State insulating cylinder inwall and be provided with the inward flange for positioning the upper bracket.
Using above-mentioned technical proposal, replace needing the lower aluminum frame of assembling using the inner fixed stand integrated with insulating cylinder,
Reduce installation step.On the premise of production error symbol required precision is ensured, can more accurate quick using inner fixed stand
Vacuum interrupter is positioned.Therefore the program simpler can efficiently assemble vacuum circuit breaker, and disqualification rate declines, raw
Produce efficiency high.
The end being flexible coupling can directly have insulated tension pole to be fixed on vacuum interrupter lower end, and simple structure, connection are reliable, dress
It is fast with speed.The upper bracket is filled in after insulation with vacuum interrupter, on the one hand can be positioned by inward flange, on the other hand logical
Crossing wire outlet seat can be while be fixed installation, simple structure, efficiency high to the two.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Labelling in figure for：
1st, insulating cylinder, 1.1, inner fixed stand, 2, upper bracket, 3, upper wire outlet seat, 4, contact arm, 5, Mume flower contact, 6, vacuum goes out
Arc chamber, 7, lower wire outlet seat, 8, be flexible coupling, 9, insulated tension pole.
Specific embodiment
Below against accompanying drawing, by the description to embodiment, this utility model specific embodiment is made further in detail
Explanation, with help those skilled in the art to this utility model design, technical scheme have more complete, accurate and deep reason
Solution.
As shown in figure 1, this utility model provides a kind of vacuum circuit breaker of a major loop, including insulating cylinder 1, insulation
Cylinder 1 is built with vacuum interrupter 6.There is in insulating cylinder 1 inner fixed stand 1.1 of molding in conjunction, inner fixed stand 1.1 has to be used
In the centre bore for installing vacuum interrupter 6.1 side of insulating cylinder has the through hole for being used to installing wire outlet seat 3 and lower wire outlet seat 7.
The inward flange of positioning upper bracket 2 is additionally provided with 1 inwall of insulating cylinder.
6 upper end of vacuum interrupter is provided with upper bracket 2, and the two together loads in insulating cylinder 1.Wear 6 lower end of vacuum interrupter
The centre bore for crossing inner fixed stand 1.1 is connected with the insulated tension pole 9.It is provided with insulating cylinder 1
The upper wire outlet seat 3 and lower wire outlet seat 7 of 6 upper and lower end position of room, side of the upper wire outlet seat 3 by screw with the upper bracket 2 is fixed
Connection.So upper bracket 2 and inner fixed stand 1.1 are together fixed on vacuum interrupter 6 in insulating cylinder 1, prevent which from shaking,
Collision, it is ensured that the reliance security of vacuum circuit breaker.
Lower wire outlet seat 78 is connected with 6 lower end of vacuum interrupter by being flexible coupling, and 9 connection end of insulated tension pole is through being flexible coupling 8
End be fixed between 6 lower end of insulated tension pole 9 and vacuum interrupter.8 other ends that are flexible coupling are fixed by screws in down
Wire outlet seat 7, connects and again lower wire outlet seat 7 is arranged on insulating cylinder 1.This connected mode simple structure, connection are reliable, assembling
Speed is fast.Contact arm 4 is installed on upper wire outlet seat 3 and lower wire outlet seat 7 respectively afterwards, the external part of contact arm 4 is provided with Mume flower contact
5。
This vacuum circuit breaker replaces needing the lower aluminum frame of assembling by inner fixed stand 1.1, reduces installation step.Protecting
On the premise of card production error symbol required precision, using inner fixed stand 1.1 can more accurate quick vacuum interrupter 6 carried out
Positioning.Therefore structure is this solution simplifies, and simpler can efficiently assembles vacuum circuit breaker, disqualification rate declines, production
Efficiency high.
This utility model is exemplarily described above in conjunction with accompanying drawing, it is clear that this utility model is implemented not to be received
The restriction of aforesaid way, as long as employing changing for the various unsubstantialities that the design of this utility model method and technical scheme are carried out
