Description
Technical field
The utility model is related to a kind of switch cabinet shutter opener, and in particular to a kind of 12kV minimizes high-tension switch cabinet
Valve opener.
Background technology
Because more users propose the requirement of reduction floor space to high-tension switch gear so that 12kV is high in recent years
The cabinet width that compresses switch progressively reduces, can only be to cabinet and valve mechanism in the case where existing breaker overall dimension can not reduce
Width significantly compressed.
There is producer that valve opener is employed into unilateral crutches arm in miniaturization high-tension switch cabinet and coordinate link mechanism
The pattern of unlatching, relies only on left side while carrying out the unlatching of valve.This side valve opener that sacrifices exchanges that cabinet is wide to be subtracted for
Both sides unbalance stress when small mode causes the valve to open, needs during reset by the weight difference between upper valve and lower valve, machine
Structure is unreliable.And the matched element such as traditional valve, valve guide rod and circuit breaker chassis can not all be continued to use completely,
There is no inheritability and versatility.
The pattern that link mechanism is opened also is coordinated using the single connecting lever in both sides in miniaturization high-tension switch cabinet, this mode is sacrificial
Valve is opened in the lower valve connecting lever of domestic animal, the cooperation for relying only on valve connecting lever and joining beam, and link mechanism node is excessive, there is mechanism
Insecure risk.

In specific embodiment of the utility model, perforate on support frame as described above, the hole on support frame is turned with upper valve
Hole on arm and lower valve connecting lever has added the padlock of locking protective effect.
In specific embodiment of the utility model, upper valve connecting lever, the lower valve connecting lever of the valve opener
The one end of valve connecting rod on the lower up and down is connected in high-tension switch cabinet, and one end correspondence connects high pressure to valve connecting rod by the top up and down
Valve plate up and down in switch cubicle, up and down valve plate be enclosed in high-tension switch cabinet and slided up and down on the guide rod of left and right, and by a left side
The distance that alignment pin limitation on right guide rod moves up and down, limits opened between valve connecting lever, lower valve connecting lever accordingly
Angle.
Positive effect of the present utility model is：The 12kV miniaturization high-tension switch cabinet valve that the utility model is provided
Opener, have compressed part and the width dimensions of cooperation, but maintain the profile and opening angle of traditional valve opener,
So that part tools and manufacture craft it also avoid the change of other elements coordinated with the opener without change,
The utility model meets the demand of miniaturization high-tension switch cabinet, also inherits fabulous versatility, reliability.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the present utility model in high-tension switch cabinet.
Embodiment
The utility model preferred embodiment is provided below in conjunction with the accompanying drawings, to describe the technical solution of the utility model in detail.
Fig. 1 is structural representation of the present utility model.As shown in figure 1, the 12kV miniaturization height in the utility model is pressed off
Cabinet valve opener 400 (referring to Fig. 2) is closed installed in the circuit breaker cart raising shade board 500 of high-tension switch cabinet and valve connects up and down
Between 100 between bar, the 12kV miniaturizations high-tension switch cabinet valve opener includes：Lower valve connecting lever 1, upper valve connecting lever
2nd, central shaft 3, lower scissors axle 4, upper scissors shaft 6, support frame 5, fixed plate 7, spring；Fixed plate 7 is disconnected installed in high-tension switch cabinet
On left side plate in the device room of road, positioning fixation is played.Support frame 5 is arranged in fixed plate 7, plays bracing reinforcement, is propped up
On support 5 also locking protective effect can be carried additionally by hole in perforate, with upper valve connecting lever 2, lower valve connecting lever 1.Central shaft 3
It is installed in fixed plate 7, sleeve spring, upper valve connecting lever 2, lower valve connecting lever 1 on central shaft 3；Spring is located at the upper He of valve connecting lever 2
Between lower valve connecting lever 1, upper scissors shaft 6 is arranged on upper valve connecting lever 2, and lower scissors axle 4 is arranged on lower valve connecting lever 1.
As shown in Fig. 2 the upper valve connecting lever 2 of valve opener, lower valve connecting lever 1 be connected to above and below valve connecting rod 100
One end on the lower, one end corresponds to valve plate 300 above and below connection to valve connecting rod 100 by the top up and down, and valve plate 300 is enclosed on up and down
Slided up and down on left and right guide rod 200, and the distance that the alignment pin limitation on left and right guide rod 200 moves up and down, accordingly
Limit the angle opened between valve connecting lever 2, lower valve connecting lever 1.
The connecting lever of valve up and down of valve opener is compressed into above and below scissor-shaped and opened by raising shade board on circuit breaker cart, connection
Valve connecting rod above-below direction motion above and below band, then valve plate is opened above and below valve connecting rod drive up and down up and down.
When circuit breaker cart is pushed into breaker chamber, raising shade board 500 is by upper scissors shaft 6 and lower scissors axle on circuit breaker cart
4 are compressed to the direction of central shaft 300, and valve connecting lever links up and down is compressed to central axis direction, and upper valve connecting lever is moved upwards, lower work
Door connecting lever is moved downward, and is at this moment the opening of valve opener；When circuit breaker cart backed off after random breaker chamber, up and down
Scissors shaft also exits the compression of raising shade board on handcart, recovers nature under the action of the spring, and valve connecting lever also links extensive up and down
Multiple nature, upper valve connecting lever is moved downward, and lower valve connecting lever is moved upwards, is at this moment exactly the pass of whole valve opener
Closed state.
The valve opener utilizes scissor lever principle, and upper and lower valve connecting lever chooses curtain by circuit breaker cart
Plate united opening, lower valve connecting lever resets by spring contraction, and upper valve connecting lever relies on valve self-weight reset.But the valve mechanism
Overall width after part and assembling is all greatly compressed, and saves space.
The mechanism by upper valve connecting lever by bent plate be changed to can one-time formed flat board, the bending angle of lower valve connecting lever is also big
Width reduces, and the central axle sleeve between two connecting levers shortens, and axle sleeve spring reduces the number of turns.
This kind of valve opener is to have compressed upper and lower door connecting lever bending angle and central axle sleeve size, to realize totality
The diminution of size after assembling.
This kind of mechanism, which does the best, have compressed the width dimensions of part and cooperation, but maintain the profile of traditional valve opener
And opening angle so that part tools and manufacture craft it also avoid what the other and opener coordinated without change
The change (such as handcart guide rail, valve guide rod, breaker raising shade board can keep original appearance and size) of element, so the valve
Opener meets the demand of miniaturization high-tension switch cabinet, also inherits fabulous versatility, reliability.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the utility model spirit and scope are not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed the utility model, the utility model
Claimed scope is by appended claims and its equivalent thereof.
