Description
Technical field
The utility model is related to power overhead network porcelain insulator, more particularly, to a kind of duplex pillar anti-pollution porcelain insulating
Son.
Background technology
With the fast development of China's electric power, electrotechnical porcelain product dosage also increasingly increases.Porcelain insulator is one of electrotechnical porcelain product,
It is for supporting and fixing busbar and energized conductor, and makes to have between energized conductor or between conductor and the earth enough distances and absolutely
The part of edge is to play a part of to support conducting wire in overhead transmission line and prevent electric current from returning ground.At present according to the work of porcelain insulator
Mode difference is divided into suspension type, pin type and pillar insulator, and wherein pillar insulator is wanted to apply in overhead transmission line most, in actual fortune
In, pillar insulator will not only have high mechanical strength（Mainly tension and bending strength）, and to have it is high it is electrical absolutely
Edge（Impulse withstand voltage, antifouling property, breakdown voltage etc.）, but due to the limitation of insulator structure, existing pillar porcelain insulating
Sub- mechanical strength is connected by steel bushing with porcelain body using adhesive layer to be influenced, and the mechanical strength of junction can't fully meet above-mentioned
It is required that use is somewhat limited.
Utility model content
The mechanical strength present in middle pillar insulator can't fully meet higher use and want for the above-mentioned prior art
The problem of asking, the utility model provide that a kind of mechanical strength higher, electric insulating quality are good, a kind of big duplex column of use scope
Formula anti-pollution porcelain insulator.
The technical problems to be solved in the utility model is adopted the technical scheme that：A kind of duplex pillar anti-pollution porcelain is exhausted
Edge, it includes insulator body, connection steel bushing and steel feet, the insulator body inner cavity and passes through adhesive phase II and steel feet phase
Even, inline steel cap being provided on the porcelain core of the insulator body, the inline steel cap is connected with porcelain core with trapezoidal thread,
Be both provided with wave groove on inline steel cap outer surface and on connection steel bushing inner surface, connection steel bushing by adhesive phase I with it is inline
Steel cap is connected, and cushion pad is provided between inline steel cap upper surface and connection steel bushing, and the connection steel bushing has flange, flange
Connecting hole is provided on side, the first full skirt and the second full skirt are provided in the insulator body, the second full skirt outer end is set
Outer ring body is equipped with, the second full skirt inner cavity is provided with inner ring body.
The utility model is due to compact-sized, uniform wall thickness, fires quality height, then is since alumina content reaches in product
To 40-50%, thus product good mechanical property；In the case where reducing quality, outer ring body, inner end and inner ring are equipped in the second full skirt outer end
Body is connected, and so can not only improve product comprehensive performance, but also can reduce cost of goods manufactured, the amount of cutting down the consumption of raw materials；It is again
In increase by one is connected with trapezoidal thread with insulator body upper end with glue between original connection steel bushing and insulator body
Even steel cap, will connect lofty and steep cap with adhesive phase and inline steel cap connects, and so be greatly improved connection steel bushing and insulation
The connection mechanical strength of sub- body, the utility model mechanical strength are higher by 20-30% than existing similar product mechanical strength, make absolutely
Edge connects more stable and reliable in the line, it is ensured that overhead transmission line trouble free service.

Chamber passes through adhesive（Cement or industrial glue）Layer II 9 is fixedly linked with steel feet 8, is provided on the porcelain core of the insulator body interior
Join steel cap 12, be provided with cushion pad 11 on inline steel cap, the porcelain core 10 of the inline steel cap and insulator body uses trapezoidal thread
（Screw pitch is square）It is connected, colloid is coated on trapezoidal thread, inline steel cap forms one with insulating body after curing, connects steel
Set upper side has flange 1, has connecting hole 13 on flange, connects and is fixed between steel bushing and inline steel cap with adhesive layer I 5
It is connected, outer diameter identical the first full skirt 3 and the second full skirt 4 is provided in the insulator body, the second full skirt outer end is set
It is equipped with outer ring body 6, the second full skirt inner cavity is provided with inner ring body 7, and the angle of 3 outer surface of the first full skirt and horizontal plane is 15-20 °,
The angle of second full skirt, 4 outer surface and horizontal plane is 20-30 °.
