Abstract
A kind of adjustable oily buffer unit of high-voltage switch gear, is related to oily buffering field.The high-voltage switch gear, cylinder seat is removably attachable to the lower end of cushion dashpot, once the part in oily buffer unit needs to change, direct opening, its is simple in construction, be easy to the replacement of part, has greatly saved cost.In addition, the cushion effect of the structure is also adjustable, by change the size for unloading oilhole, back-moving spring elastic force, change the ratio of oil, and then adjust cushion effect size, suitable oily buffer unit can be obtained according to actual requirement of engineering, its accommodation is more extensive.
Description
Technical field
The utility model is related to oily buffering field, more particularly to a kind of adjustable oily buffer unit of high-voltage switch gear.
Background technology
The end of existing oily buffer unit rivets the seal washer of multilayer, although this seal washer can be effective
Realize sealing to oily buffer unit, but due to after riveting oily buffer unit it is non-dismountable, cause its internal damping power non-adjustable
Section, device once breaks down, and can only re-replace oily buffer unit, its cost is very high, is unfavorable for the production fortune of enterprise
OK.
The content of the invention
In view of the deficienciess of the prior art, the utility model proposes a kind of adjustable oily buffer unit of high-voltage switch gear, it sets
Meter is reasonable, simple in construction, be easily installed.
In order to solve the above technical problems, the technical scheme that the utility model is used is：A kind of adjustable oil of high-voltage switch gear is slow
Flushing device, including casing and be arranged in casing contactor, auxiliary switch, worm screw, turbine, gear, motor, oil buffering
Device, energy storage crank, limited block, bearing pin, sleeve and energy-stored spring, wherein, oily buffer unit, including with female buffering
Cylinder body, the back-moving spring being arranged in cushion dashpot body and with the piston rod for unloading oilhole, are characterized in that, on the piston rod
Also it is socketed with externally threaded cylinder seat, cylinder seat is connected by external screw thread with buffering the internal thread of cylinder body, cylinder seat removably connects
The lower end of cushion dashpot is connected on, the gap between buffering cylinder side wall and piston rod is provided with sealing ring.
Described cylinder seat is secured by bolts on buffering cylinder body again.
Oily buffer unit is arranged on wall box, is spirally connected with the female limited support block of band that is fixed on wall box
Together.
The beneficial effects of the utility model：The high-voltage switch gear is adjustable oily buffer unit, cylinder seat is removably attachable to buffering
The lower end of cylinder, once the part in oily buffer unit needs to change, direct opening, its is simple in construction, be easy to part more
Replace, greatly saved cost.In addition, the cushion effect of the structure is also adjustable, by changing the size of unloading oilhole, back-moving spring
Elastic force, changes the ratio of oil, and then adjusts cushion effect size, and the oil buffering being adapted to can be obtained according to actual requirement of engineering and is filled
Put, its accommodation is more extensive.
