Description
Technical field
The present invention relates to the buffering equipment in distribution network system, more particularly to a kind of for the novel of intelligent on-pole switch
Buffer and its separating brake control method.
Background technology
At home and abroad in distribution network system, intelligent on-pole switch is as line protective device by wide model application.Automatic circuit is made
For intelligent on-pole switch it is a kind of can quick, multiple breaking and making short trouble in a short time device, be applied to transformation
Device outgoing line side realizes route protection function, provides power supply reliability.And in the operational process of automatic circuit, have 70%~80%
Failure cause be product mechanical breakdown, therefore improve automatic circuit mechanical stability be a urgent problem.It is overlapping
During in the mechanical movement of device, opening velocity is fast, and separating brake energy is high, in order to allow the moving object of high speed, big quality to stop rapidly
Stop and, and do not damage, must buffer.Cushion performance largely affects the mechanical stability of automatic circuit.Existing industry
Interior commonly used there are mainly two types of structure buffer structure, one is rubber pad buffering, another kind is oily buffering.
Oil buffering, as the term suggests last stopping, into row buffering, is reached to huge impact force by the resistance of liquid oil
Effect.Oil bumper is by being ramed, piston, oil sealing, spring, hydraulic oil, lubricating cup etc. form, and is rushed by external force when by raming
It hits, will drive the hydraulic oil of piston press inner tube, and after hydraulic oil is pressurized, by by the outage oil extraction of inner tube, meanwhile, by interior
The hydraulic oil of pipe discharge flows to inner tube from the oil return hole of inner tube；Once external force disappear, spring by piston rebound initial point wait for next time
The progress of work.
Rubber pad buffering is superimposed by multilayer thin rubber sheet to be formed, and in order to increase cushion rigidity, is also had in rubber pad
Between be inserted into sheet metal structure.Rubber pad buffers the inherent characteristic due to rubber itself, although playing the role of buffering,
But some problems are also brought simultaneously：
1, cause the rebound of automatic circuit separating brake big：The rebound of automatic circuit separating brake refers to that automatic circuit movable end of vacuum arc extinguishing chamber moves to
After sub-gate position, due to the high elastic modulus of rubber pad, entire transmission chain is caused to be moved to separating brake negative direction, at this time movable end of arc extinguishing chamber
It is exactly separating brake rebound amount to be transmitted the distance that chain reversely drives.For the automatic circuit fracture distance of 15.5kV in 9mm or so, rubber pad is slow
Rebound amount is rushed 20%~50%, in the worst case, rebound motion to extreme position, fracture distance only has 4.5mm, very
Square root of the aerial resistance to voltage levels about between two electrodes at positive [1], be on close level in having dropped by port isolation at this time
30% or so, cause fracture to puncture hidden danger.It is cut-off when automatic circuit encounters capacity current, the overvoltage of this operating mode more makes this hidden danger
Aggravation.
2, short life：Rubber pad buffers generally existing short life problem, after automatic circuit runs 200 operations, rubber pad
Just start outlet invagination phenomenon.After automatic circuit runs 2000 operations, rubber pad invagination is deepened, and the divide-shut brake characteristic of coincidence is bent
Line has begun to deviate envelope (± 5%).After automatic circuit operation 8000, rubber pad invagination is more serious, point of automatic circuit
Combined floodgate characteristic curve has completely offset from envelope, and the cushion stroke of buffer has been greatly reduced at this time.Cushion stroke decline is led
Cause snubber energy decline, can not absorbed impact force will reduce entire transmission chain mechanical stability decline.
3, not low temperature resistant：At low ambient temperatures, rubber material relaxation drastically slows down, hardness, elasticity modulus and molecule
Interior increased friction, elasticity significantly reduce, and elasticity significantly reduces, and working performance is remarkably decreased, outstanding when in particular by dynamic impulsion
It is apparent.The automatic circuit run at low ambient temperatures, when maintenance, will often find that the phenomenon of rubber buffer breakage.
The features such as oil buffering has buffering small, low temperature resistant, and noise is small, but there is also some problems simultaneously：
1, reflux is slow：When oil is buffered in first time separating brake, cushioning effect can be functioned well as.But automatic circuit is due to having
The characteristics of continuous several times quickly overlap when oil is buffered in second of separating brake, since hydraulic oil is not yet returned to start work point, is led
Second of cushion performance is caused to decline to a great extent.If coincidence sequence t2, the t3 value setting value ＜ 100ms of automatic circuit, third time, the 4th
The oily cushion performance of secondary coincidence can further decline.
2, oil leak：Due to the powerful impact force of automatic circuit separating brake, oil sealing will undertake hydraulic oil whole recoil strength, therefore sometimes
It will appear oil sealing can't bear the heavy load, buffer oil leak.If oil buffering oil leak, the cushion performance of oil buffering will be by lethal damage.
