Detailed description of the invention
In conjunction with accompanying drawing, the invention will be further described, the technical scheme is that the technical solution used in the present invention is:
Breaker in extra high voltage hydraulic pressure spring operating mechanism, by main body module 1, accumulation of energy chunk 2, monitoring modular 3, relief valve module
4, pressurising module 5, control module 6, fuel tank 7 and mounting bracket composition, each functional module element, use modularity integrated
Design, main body module is the main part of this operating mechanism, and two disc spring accumulation of energy chunks are symmetrically distributed in about main body module
Both sides；Control module, relief valve module, monitoring modular are arranged in before main body module；Pressurising module arrangement is in main body mould
After block, the auxiliary part such as fuel tank and mounting bracket is arranged in above main body module, and each functional module is all independent
Assembly, each functional module can install or remove according to a little entirety from main body module.
Main body module is box-shaped structure, and working cylinder assembly and energy storage component are become one formula structure by main body module, main body mould
The Master cylinder body of block is composite structure, and main body cylinder block is large-scale wrought aluminium component, and cylinder core is alloy steel piece, and control module uses
The two-step evolution structure of big flow, have employed independent two group disc spring accumulation of energy chunk, and two accumulation of energy chunks are arranged symmetrically in master
Module both sides, each accumulation of energy chunk is prepackage type structure, and single group accumulation of energy chunk can be with integral disassembly, assembly, the inside of die block
Pressurising, have employed around uniform three the plunger auxiliary pumps of rotary shaft.
The operation principle of the present invention: as the hydraulic pressure spring operating mechanism operation principle of prior art:
The tank circuit power transmission of mechanism, electric motor starting, through pressurising module 5, hydraulic oil squeezed into main piston rod 8 top, energy storage
Piston 10 top, the combined floodgate passage of control valve and the channel cavity of relief valve.Meanwhile, when pressurising module is suppressed, energy storage
Energy storage piston in assembly 9 stretches out under the pressure of high-voltage oil cavity mesohigh oil, the disk spring energy storage in compress energy storage chunk simultaneously
, after Chu Manneng, the travel switch in monitoring modular cuts off motor tank circuit.
Now, main piston rod top is hydraulic oil, and bottom communicates, for low pressure oil with the Z mouth of Two-stage control valve in control module
, mechanism is in gate-dividing state.Combined floodgate one-step valve action, the commutation of Two-stage control valve, Two-stage control valve is controlled by control module
P mouth and Z mouth conducting, hydraulic oil import main piston rod bottom, the upper and lower cavity of main piston rod is all hydraulic oil, because of following
Oil pressure area ratio above big, according to differential pressure principle, main piston rod moves upward, it is achieved close a floodgate.After combined floodgate, auxiliary is opened
Close conversion and cut off secondary closing circuit；Monitoring modular starts motor pressurising simultaneously, is automatically stopped after energy storage is full.Mechanism is protected
Hold in "on" position.Mechanism is when "on" position, and when separating brake one-step valve action, Two-stage control valve commutates, makes Z mouth and T mouth
Conducting, the piston upper of such main piston rod is hydraulic oil, becomes low pressure oil below.So main piston rod moves downward,
Realize separating brake.After separating brake, secondary sub-gate circuit is cut off in auxiliary switch conversion；Monitoring modular starts motor pressurising, energy simultaneously
Amount Chu Manhou is automatically stopped.Mechanism is maintained at gate-dividing state.
As can be seen here, the present invention has integrated height, easy to maintenance, output function merit super large, amount of parts are few, knot
The plurality of advantages such as structure is simple, reliability is high, length mechanical life, are especially suitable for breaker in extra high voltage and support the use.The present invention
