Abstract
The utility model discloses a kind of novel breaker operating mechanism oil bumper, it is characterized in that, comprise cylinder body and cylinder interior suit on the piston rod and on described piston rod, do the piston of straight reciprocating motion; And described piston and described cylinder interior are combined closely, and cylinder interior is divided into Liang Ge grease chamber, described grease chamber inwall is provided with the turnover oilhole that upper and lower two drain path are interconnected; Described drain path is built with choke valve.This kind of novel breaker operating mechanism oil bumper is compared with existing oil bumper, and oil bumper of the present utility model, by regulating the aperture of choke valve, changing buffer capacity, regulating circuit-breaker switching on-off speed.
Description
Technical field
The utility model relates to a kind of oil bumper, is specially a kind of novel breaker operating mechanism oil bumper.
Background technology
At present, at High-voltage Switchgear Industry, oil bumper is widely used.When the operation principle of buffer is piston forward impelling, grease chamber's inner fluid will be closed, make it pass through turnover oilhole and discharge grease chamber, closed fluid acts on piston because extruding produces compensator or trimmer pressure, resist mutually with the inertia force of piston, to reach the object of retarding braking.Oil bumper on open market carries out the adjustment of hydraulic oil flow velocity by the turnover oilhole opening different size on inner cylinder body, for ensureing breaker open operation speed, buffer need repeatedly regulate, and when on market, current conventional oil bumper regulates at every turn, all need to take outer shell apart, regulate shock-absorbing capacity by setting up or block turnover oilhole quantity, make circuit breaker find suitable opening velocity, operate very time-consuming.
Utility model content
The technical problems to be solved in the utility model overcomes existing defect, provides a kind of novel breaker operating mechanism oil bumper, under the condition not dismantling oil bumper, can regulate divide-shut brake speed, thus solve the problem.
For achieving the above object, the utility model provides following technical scheme: a kind of novel breaker operating mechanism oil bumper, comprises cylinder body and cylinder interior suit on the piston rod and on described piston rod, do the piston of straight reciprocating motion; And described piston and described cylinder interior are combined closely, and cylinder interior is divided into Liang Ge grease chamber, and grease chamber's inwall is provided with the turnover oilhole that upper and lower two drain path are interconnected; Described drain path is built with choke valve.
Further, what be provided with adjustment drain path size in described choke valve unscrews lock nut.
Further, described grease chamber is front grease chamber and rear grease chamber.
Compared with prior art, the beneficial effects of the utility model are: this kind of novel breaker operating mechanism oil bumper is compared with existing oil bumper, and oil bumper of the present utility model, by regulating the aperture of choke valve, change buffer capacity, regulate circuit-breaker switching on-off speed.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in detail, to make above-mentioned advantage of the present utility model definitely.
Fig. 1 is a kind of novel breaker operating mechanism oil bumper structural representation described in the utility model;
In figure: 1, cylinder body; 2, piston; 3, piston rod; 4, front grease chamber; 5, rear grease chamber; 6, drain path; 7, choke valve.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment; technical scheme in the utility model embodiment is clearly and completely described; obviously; described embodiment is only the utility model part embodiment; instead of whole embodiments; based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model provides a kind of technical scheme: a kind of novel breaker operating mechanism oil bumper, comprises cylinder body 1 and cylinder body 1 internal sleeve and to be contained on piston rod 3 and the piston 2 doing straight reciprocating motion on described piston rod 3; And described piston 2 is combined with described cylinder body 1 inner tight, and cylinder body 1 inside is divided into Liang Ge grease chamber, grease chamber's inwall is provided with the turnover oilhole that upper and lower two drain path 6 are interconnected; Described drain path 6 is built with choke valve 7.What be provided with adjustment drain path 6 size in described choke valve 7 unscrews lock nut.Described grease chamber is front grease chamber 4 and rear grease chamber 5.
Concrete principle: when circuit breaker carries out separating brake action, piston 2 is advanced forward by the promotion of piston rod 3, constantly hydraulic oil in the front grease chamber 4 of extruding, and hydraulic oil liquid acts on piston 2 because extruding produces compensator or trimmer pressure, resist mutually with the inertia force of piston 2, reach deceleration buffer effect.In front grease chamber 4, hydraulic oil enters drain path 6 by turnover oilhole, is circulated to rear grease chamber 5, ensure that the balance of cylinder interior pressure.
The utility model is a kind of novel breaker operating mechanism oil bumper and compared with existing oil bumper, oil bumper of the present utility model, by regulating the aperture of choke valve, changing buffer capacity, regulating circuit-breaker switching on-off speed.
Last it is noted that the foregoing is only preferred embodiment of the present utility model; be not limited to the utility model; although be described in detail the utility model with reference to previous embodiment; for a person skilled in the art; it still can be modified to the technical scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
