Bar；
The barricade is located at the outside of stiffening plate, and the outer edge of barricade is surrounded by aluminum stranded conductor, is enclosed with wrinkle outside aluminum stranded conductor
Line paper, barricade surrounding are equipped with several first holes at outer peripheral position, and successively helical form passes through each the to tape
Aluminum stranded conductor to be fixed behind one hole, i.e., tape is extend into first hole from the back side of barricade, it is stretched out from barricade front,
Then it is extend into next first hole after being passed through from the aluminum stranded conductor outside for being enclosed with crimped paper from the back side of barricade, with such
It pushes away, until passing through the first all holes.The side of barricade is completely covered for tape, aluminum stranded conductor after binding.Aluminum stranded conductor docking
Place's STT-120 aluminum pipe docks, and is grounded on the connecting plate that docking one strand of punishment is connected in barricade with STD-35 end.
Each corner of barricade is provided with the second hole；
The outside of barricade be equipped with barricade cardboard, barricade cardboard by identical three layer of 2 millimeters thick of shape cardboard and stay
Composition sets stay, intermediate layer paperboard and upper layer between each corner of lower layer paperboard and each corner of intermediate layer paperboard
Stay on several is set between cardboard, upper stay is located at the surface of lower stay；On the upper layer cardboard above each upper stay
All beat the through-hole through entire barricade cardboard；I.e. each through-hole is located at each corner of barricade cardboard.Barricade cardboard with
The shape of barricade is identical.
Barricade cardboard and barricade are bound together by several tapes, i.e., each tape is respectively protruding into
It is bound after in barricade hole corresponding with shielding each corner of cardboard.
Barricade there are two connecting plate, has unthreaded hole on connecting plate, the unthreaded hole on connecting plate, which covers, to be added towards stiffening plate one side
It after spot welding threaded rod on strong plate, is tightened with nut, realizes the connection of barricade and stiffening plate.Stiffening plate is towards core side, screen
Shield plate cardboard is towards voltage equalizing ball side.
The invention has the advantages that being welded into hanging for flute profile using thick steel plate to improve the anti-short circuit capability of core clamp
Axis steel plate, flute profile hanging axis steel plate inside are welded with stiffening plate, do the supporting role of wire-lead folder.To solve the problems, such as wedge angle, adding
Strong plate is equipped with barricade, can reduce lead and casing voltage equalizing ball to the insulation distance of folder, reduce transformer cost.
