Description
Technical field
The present invention relates to a kind of technical field of power equipment, more particularly to a kind of pole.
Background technology
At present in known medium-voltage equipment, the pole of vacuum switch tube is simply carried out to vacuum switch tube body
Sealing, enhances its external insulation, but its moving contact does not carry out sealing with insulated tension pole coupling part, so existing solid
All there is cavity inside sealed pole around insulated tension pole.The processing for this cavity uses air insulation, SF6 gas mostly at present
The insulation mode of body insulation, but the insulation volume of air insulation is big, insulating properties are poor, influenceed easily to cause equipment by outdoor environment
Insulation breakdown；And SF6 gases can not also be easily caused in insulation decline after High aititude or extremely cold area application, the leakage of SF6 gases
Equipment explosion, and sulfur hexafluoride belongs to greenhouse gases, not environmentally, is not easily recycled.So finding a kind of complete pole
Mode, is to improve apparatus insulated performance, reduce the only way which must be passed that electric power accident occurs.
The content of the invention
To solve the above problems, the present invention provides a kind of pole.
The technical scheme is that：A kind of pole, including insulating coating, the interior first half positioned at insulating coating
Pole vacuum switch tube, the insulated tension pole component positioned at the interior lower half of insulating coating, insulated tension pole component upper end lead to
Cross to be flexible coupling and be connected with pole with the lower end of vacuum switch tube；The bottom of described pole vacuum switch pipe outer wall
The positioning spacer of annular, the vacuum switch tube external insulation of the pole on positioning spacer top are supported by between insulating sleeve
Hard silicon rubber is filled with cavity in overcoat；In positioning spacer bottom pole vacuum switch tube, be flexible coupling, drawing of insulating
Soft silicon rubber is filled with cavity between bar assembly and insulating coating, insulating coating lower end and insulated tension pole component lower end it
Between provided with annular flexible shrouding be covered in soft silicon rubber outer end.
Described flexible shrouding is diaphragm of diaphragm pump, and the diaphragm outer is fixedly connected by big lock sleeve with insulating coating,
The interior edge of the diaphragm is connected by small lock sleeve with insulated tension pole component end.
The pole of the present invention is main by insulating sleeve, pole vacuum switch tube and insulated tension pole component group
Into, and soft silicon rubber is poured around insulated tension pole component with hard silicon rubber is poured around vacuum switch tube in pole, it is soft
Separated between silicon rubber and hard silicon rubber by the positioning spacer of fixed vacuum switch tube, and seal up with diaphragm of diaphragm pump soft silicon rubber
Glue, prevents soft silicon rubber from gushing out from pole, so that by whole pole sealing.Insulated tension pole component drives sealing
During the moving conductive rod motion of pole vacuum switch tube, the internal volume change of generation can be adjusted by diaphragm of diaphragm pump.
The material of the diaphragm of diaphragm pump utilized in the present invention uses polytetrafluoroethylene (PTFE), because polytetrafluoroethylene (PTFE) is C class B insulations
Diaphragm of diaphragm pump is applied to power equipment manufacturing technology field by material, the present invention.
By the viscosity for adjusting soft silicon rubber so that insulated tension pole can obtain certain damped coefficient when moving, from
And good second order velocity and acceleration response curve is obtained, shock loading of the closing process to arc-chutes is reduced, is improved
The life-span of arc-chutes；Separating brake overshoot is reduced to the shock loading of mechanism, the life-span of mechanism is improved.
In order to ensure that soft silicon rubber, hard silicon rubber and insulating cylinder, insulated tension pole glue connection well, insulating cylinder is drawn with insulation
Bar makes its rough surface using the process of surface treatment of sandblasting and ball blast, be more conducive to and soft silicon rubber combination.
Use vacuum casting process when pouring into a mould soft silicon rubber with hard silicon rubber, and remove moisture removal, it is ensured that it is poured be poured in after,
It is used as the excellent interior insulation performance of an entirety.
