Abstract
The utility model relates to a secondary opening tripper of a spring operation mechanism, which is aimed at the technical problem that the opening requirement of the mechanism cannot be easily implemented when the fuse of the conventional like device is fused or impacted. The secondary opening tripper comprises a side plate, an opening fastening plate component and an opening maintaining crankarm component, and the main design point of the secondary opening tripper is that both the opening fastening plate component and the opening maintaining crankarm component are components which can be independently mounted and debugged, that is, both the opening fastening plate component and the opening maintaining crankarm component can be separately mounted and debugged. After a vacuum load switch is closed, the secondary opening tripper can ensure that the counterforce generated by the vacuum load switch, which is applied on an opening half shaft via the opening fastening plate, is reduced to one fifth of the force prior to the improvement, consequently, the opening requirement of the mechanism can be easily implemented when the fuse is fused or impacted, the work needed by an opening electromagnet can be reduced as well, and thereby the performance and reliability of the CT25 spring operation mechanism are enhanced. In addition, the structure of the secondary opening tripper is simple, and the secondary opening tripper is convenient to repair and assemble, and is applicable to the improvement of the CT25 spring operation mechanism.
Description
Technical field

Background technology
Vacuum circuit-breaker because of its arc-extinguishing medium and arc extinguishing after the dielectric in contact gap all be that high vacuum is gained the name; It has volume little, in light weight, be applicable to the advantage that frequent operation, arc extinguishing need not overhaul, in power distribution network, use comparatively universal.
The technology of making vacuum interrupter in middle pressure field along with China maturation that tends towards stability, middle pressure vacuum circuit-breaker and middle pressure vacuum load switch play a leading role in distribution and electric power system.The middle demand of vacuum load switch of pressing significantly increases, wherein the FZN25-12 vacuum load switch is in great demand, it joins the CT25 spring operating mechanism a stubborn problem, be exactly after switch closes a floodgate, the counter-force that vacuum load switch produces is very big by the power that the separating brake buckle acts on the separating brake semiaxis, when making the fuse blows bump, be difficult for realizing mechanism's separating brake requirement, change existing one-level Sub-gate release device in the CT25 spring operating mechanism into the secondary Sub-gate release device by improving, after being closed a floodgate, switch make counter-force that vacuum load switch produces be decreased to 1/5 of power when not improving by separating brake buckle parts the power on the separating brake semiaxis of acting on, when guaranteeing the fuse blows bump, easily realize mechanism's separating brake requirement, the required merit of tripping electromagnet is reduced, reach high reliability and the high-performance of guaranteeing the CT25 spring operating mechanism.
Summary of the invention
For improving the deficiency of above-mentioned existence, the utility model is intended to provide to this area a kind of secondary Sub-gate release device of spring operating mechanism, make it solve existing domestic CT25 spring operating mechanism when fuse blows is clashed into, be difficult for to realize the problem that mechanism's separating brake requires, its objective is to be achieved through the following technical solutions.
A kind of secondary Sub-gate release device of spring operating mechanism, this device keeps the connecting lever parts to constitute by side plate, separating brake buckle parts and separating brake, and separating brake buckle parts comprise separating brake buckle, spacer pin, first reduction torsion spring, separating brake buckle axle, first bearing pin, second reduction torsion spring, separating brake pallet; Separating brake keeps the connecting lever parts to comprise roller, second bearing pin, connecting lever, output shaft, output toggle arm.Separating brake buckle parts and separating brake keep the connecting lever parts respectively to place on the side plate; Its main points are that described separating brake buckle parts and separating brake keep the connecting lever parts to be separate component.So-called separate component, promptly separating brake buckle parts and separating brake keep the connecting lever parts can be installed separately, debug, and this structure makes and dismantles, maintenance is comparatively convenient.
Described spacer pin, separating brake buckle axle is fixed on the side plate, separating brake buckle axle connects the separating brake buckle, groove and spacer pin that separating brake buckle one end is provided with offset, the separating brake buckle other end is by the sincere son of the hinged separating brake of first bearing pin, the described first reduction torsion spring socket separating brake buckle axle, first reduction torsion spring is that spacer pin and separating brake buckle are tightened up towards the direction that both offset, the described second reduction torsion spring socket, first bearing pin, second reduction torsion spring is the spinning reduction that plays sincere son of separating brake and separating brake buckle, second reduction torsion spring is under initial condition, and the angle of sincere son of separating brake and separating brake buckle is 90 °～120 °.After the technical essential of separating brake buckle parts is to make vacuum load switch to close a floodgate, make counter-force that vacuum load switch produces be decreased to 1/5 of power when not improving by separating brake buckle parts the power on the separating brake semiaxis of acting on, when guaranteeing the fuse blows bump, easily realize mechanism's separating brake requirement, the required merit of tripping electromagnet is reduced.
Described output shaft is fixed on the side plate, welding output toggle arm and connecting lever on the output shaft, and connecting lever one end is by the hinged roller of second bearing pin, and an end of output toggle arm connects vacuum load switch by connecting rod.After separating brake kept the technical essential of connecting lever parts to be to make vacuum load switch to close a floodgate, the counter-force that vacuum load switch is produced reduced by the power that separating brake keeps the connecting lever parts to act on the separating brake buckle parts.
When described separating brake buckle parts were in the separating brake maintenance at vacuum load switch, sincere son of described separating brake and described roller offseted.
The utility model compared with prior art has the following advantages:
(1) the secondary Sub-gate release device of this spring operating mechanism, after vacuum load switch is closed a floodgate, make counter-force that vacuum load switch produces be decreased to 1/5 of power when not improving by separating brake buckle parts the power on the separating brake semiaxis of acting on, when guaranteeing the fuse blows bump, easily realize mechanism's separating brake requirement;
(2) the secondary Sub-gate release device of this spring operating mechanism, after vacuum load switch is closed a floodgate, make counter-force that vacuum load switch produces be decreased to 1/5 of power when not improving, the required merit of tripping electromagnet is reduced by separating brake buckle parts the power on the separating brake semiaxis of acting on.
The utility model is in distribution and the electric power system, and the important device in the CT25 spring operating mechanism that the FZN25-12 vacuum load switch is joined has reasonable in design, simple in structure, safe and reliable, maintenance, easy to assembly is applicable to the improvement of CT25 spring operating mechanism.
