Description
Technical field
The utility model relates to high-voltage breaker operation mechanism buffer unit technical field, particularly a kind of primary cut-out separating brake composite multi-functional buffer unit.
Background technology
During the interior part primary cut-out separating brake using of electric power system at present, adopt hard buffer unit, by multilayer leather packing, be superimposed and reach certain thickness, lean on the decrement of rubber self to play certain cushioning effect.Sort buffer device is because buffering capacity is less, in the breaker open operation later stage, dump energy for separating brake can not be cushioned fully effectively absorption of device, form very large vibration, this vibration can produce a kind of destructive power, for machine driven system and the high pressure arc control device of circuit breaker, has a great impact.Especially for driving the vacuum circuit-breaker that only has 10 millimeter apart from (distance after breaker open operation between charged position and not charged position), itself is very strict to the spring in breaker open operation process and these two index requests that rebound, if because buffer unit can not fully effectively absorb the dump energy in separating brake later stage spring and the bounce-back superscalar data causing in breaker open operation process in time, the normal break performance of circuit breaker will directly be had influence on, when serious, can cause arc-extinguishing chamber of circuit breaker blast, consequence is extremely serious.
Utility model content
The utility model is in order to address the above problem, a kind of stable buffering, soft, friction and noise are provided, have improved buffering effect, improve damper mass, eliminated primary cut-out separating brake composite multi-functional buffer unit circuit breaker and system being worked the mischief due to vibration.
The technical solution of the utility model is: a kind of primary cut-out separating brake composite multi-functional buffer unit, comprise and be built-in with the buffer disc that the buffer cup of hydraulic oil, all sides of being positioned at buffer cup have sealing ring, the buffer bar that buffer disc top arranges passes buffer cup and is connected by oil sealing with buffer cup, on described buffer disc, through hole is set, described buffer disc is connected by spring with buffer cup bottom, and described buffer disc has the buffer stopper that tangent plane is notch cuttype.
Described buffer cup is provided with buffer bar locking mechanism.
Described buffer bar locking mechanism comprises and is arranged on the positioning sleeve that is sleeved on buffer bar and is connected with buffer cup one, is arranged on the groove matching with end part of pin shaft on buffer bar, described positioning sleeve is provided with through hole, in through hole, be provided with bearing pin, on bearing pin, be set with spring bearing pin is pressed on buffer bar.
Described buffer bar is that cross section is direction structure.
Described bearing pin one end has rocking arm, and all sides of the other end have screw thread.
Described buffer stopper lower end has rubber layer.
The vertical section of described groove is triangular structure of right angle.
Buffer unit of the present utility model is mainly combined by hydraulic cushion and these two parts of spring buffer.Hydraulic cushion comprises again level Four buffering: first-level buffer: the cylinder of buffer bar bottom, can form very little resistance in the descending process of buffer bar and between hydraulic oil.Level 2 buffering: mainly rely on buffer stopper intermediate cross-section to increase, in descending process and between hydraulic oil, form compared with slight drag.Three grades of bufferings: mainly rely on buffer stopper layer cross section to increase, in descending process and the resistance forming between hydraulic oil.Level Four buffering: mainly rely on buffer disc in descending process, the resistance forming between the through hole boring on buffer disc and hydraulic oil.Spring buffer also comprises two kinds of functions: function one: spring is subject to the downward compression of buffer disc and storage power when breaker open operation, thus the auxiliary cushioning effect while playing separating brake.Function two: when spring is prepared to close a floodgate at circuit breaker, the buffer disc of spring in confined state promotion always moves upward, the energy offset that spring discharges the move upward resistance of suffered hydraulic oil in process of buffer disc, improved the closing time of circuit breaker.This device of what is more important has rubber layer by the buffer stopper lower end arranging under buffer disc, and when active force is excessive, buffer stopper end contacts with buffer cup, prevents that spring is damaged, affects the life-span of equipment; Further, described buffer cup is provided with buffer bar locking mechanism, described buffer bar locking mechanism comprises being arranged on and is sleeved on the positioning sleeve that buffer bar is connected with buffer cup one, and described positioning sleeve is provided with through hole, is provided with bearing pin in through hole, on bearing pin, being set with spring is pressed on buffer bar bearing pin, after buffer bar declines, bearing pin is under the effect of spring, and bearing pin snaps in groove, play locking action, can not produce by mistake and close; Described bearing pin one end has rocking arm, and rocking arm is detachable, is convenient to the spring of dismantling when unclamping bearing pin; The all sides of the other end have screw thread, after the spring of dismantling, by rotating rocking arm, bearing pin are dismantled, and complete breaker switching-on operation; The vertical section of described groove is triangular structure of right angle, and bearing pin can slide in groove, reduces the impulsive force that bearing pin is subject to, and avoids the stressed bearing pin that damages greatly of bearing pin.Described buffer bar is that cross section is direction structure, plays guide effect, is convenient to bearing pin and inserts groove.
