Description
Technical field
The present invention relates to a kind of pole and application method, particularly a kind of double-fracture pole for being used to cut electric capacity
And application method.
Background technology
Vacuum switch is restriked, repeated breakdown is primarily due to inrush phenomenon and causes vacuum arc-extinguishing chamber contact melting welding, so as to
Field is caused caused by breakdown caused by breakdown weak points are formed after separating brake；It could also be possible that exist in vacuum interrupter uncertain
Particulate and cause sluggish breakdown occurs after separating brake.
Inrush phenomenon value during switched capacitor group is from several kiloamperes to more than ten kiloamperes, although current value is not too big,
But the frequency shoved is very high, up to several KHzs, it is also harsh that its fuel factor ratio does 31.5KA heat stabilization tests.And vacuum switch
Dynamic/static contact is the contact of plane dock, is point contact on stricti jurise, thus vacuum switch is doing the examination of switched capacitor group
It is inevitable that melting welding occurs when testing.After separating brake, contact surface melting welding point is necessarily at electric field concentration, is subject to recover pressure-resistant thin
Weak-strong test.Can the pattern after melting welding point is opened most important for bear recovery voltage after vacuum interrupter separating brake, and its
Pattern has substantial connection with the opening characteristic of switch and the structure property of contact material.
It is prone to repeated breakdown during vacuum switch switched capacitor group, the defects of being a kind of obvious.According to relevant information introduction,
First Pass Yield during current domestic 10KV vacuum switches switched capacitor is about 70~80%, 35KV vacuum switch switching capacitances
First Pass Yield during device is only 20% or so.
The vacuum circuit breaker of external major company's vacuum interrupter product is done well used in 10KV voltage class, but 35KV electricity
Pressure grade also is difficult to by cutting capacity test.
Therefore it is proposed out in 35KV voltage class, such a scheme of vacuum circuit breaker with double breaks for cutting electric capacity
Come, and pass through verification experimental verification, effect is pretty good.
But non-coaxial cascaded structure is mainly used currently used for cutting the vacuum circuit breaker with double breaks of electric capacity its double-fracture,
Two arc-chutes during divide-shut brake in each pole need two control sticks to be operated, and original mechanism can not use, must
Special operating mechanism must be developed.Therefore vacuum circuit breaker has the drawback that at present：Structure and control are complex, general
Property is poor, and its corresponding manufacturing cost is also higher.
The content of the invention
It is an object of the present invention to provide a kind of double-fracture pole and application method for being used to cut electric capacity.The present invention
With structure, simple, the versatile feature low with equipment investment cost of control.

Line is simultaneously moved by the direction of double acting arc-chutes to arc-chutes, and during motion, action bars promotes electrode B ' motion, make electrode B ' and electricity
Pole B is contacted, and is completed two level and is closed a floodgate；Action bars continues to move, the electrode B through combined floodgate ' and electrode B promotion conducting rod motion, and press
Division brake spring, conducting rod promote electrode A ' motion, make electrode A ' to be contacted with electrode A, complete one-level combined floodgate.
Compared with prior art, the present invention is provided with arc-chutes, trip device and double in enclosure interior sequentially coaxially line series winding
Dynamic arc-chutes；A pair of electrodes A and A' are set in arc-chutes, a pair of electrodes B and B' are set in double acting arc-chutes；Electrode A ' and
Electrode B is respectively arranged on conducting rod both ends, and limiting plate is set on the conducting rod in trip device, limiting plate through sluice separating spring with
Trip device one end connects, and the trip device other end is provided with limiting stand；The structure, realize double-fracture (i.e. a pair of electrodes A, A ' and one
To electrode B, B ') coaxial line be arranged in series, structure is simpler；In addition, it is of the invention, using an existing one control lever just
It can complete point, closing operation, without redesigning the special matched use of operating mechanism, not only versatility is stronger, and
And R＆D fund is effectively saved, reduce equipment cost.It is of the invention compared with existing pole, manufacturing cost can reduce
About 20%, its circuit breaker cost assembled can reduce about 30%.
The present invention sets trip device between arc-chutes and double acting arc-chutes, realizes the disjunction of pole double-fracture, thus
The design of pole and the design of breaker have been simplified, has reached the purpose of cutting capacitive load.In addition, point of the invention
Lock, the separating brake (i.e. one-level separating brake and two level separating brake) of double-fracture need to be only realized by the motion of action bars；Close a floodgate, also need to only pass through
The motion of action bars is realized close a floodgate (i.e. one-level is closed a floodgate and two level is closed a floodgate)；Therefore its control, operate it is simpler.
In summary, the present invention has the present invention with structure, controls simple, versatile spy low with equipment investment cost
Point.
