Utility model content
Technical problem to be solved in the utility model is: provide a kind of oil-filled transformer increasing coil mechanical strength.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of oil-filled transformer, comprise iron core, containing three coils in iron core, coil is respectively arranged with some coil cushion blocks, the upper end of iron core is clamped by two upper clamping pieces, the lower end of iron core is clamped by two lower clamping pieces, be connected by some upper stretching screws between two upper clamping pieces, be connected by some lower stretching screws between two lower clamping pieces, be connected respectively by perpendicular stretching screw between the described upper clamping piece at iron core homonymy and lower clamping piece, upper clamping piece and lower clamping piece are channel-section steel, and the notch of two upper clamping pieces is contrary, the notch of two lower clamping pieces is also contrary, the face that upper clamping piece is relative is welded with respectively two corresponding upper angle steel, and angle steel lays respectively at the two ends of upper clamping piece on two, the face that lower clamping piece is relative is welded with respectively two corresponding lower angle steel, and twice angle steel lay respectively at the two ends of lower clamping piece, upper angle steel and lower angle steel offset with corresponding coil cushion block respectively.
Described upper angle steel bottom surface is respectively arranged with round steel, the upper end face of lower angle steel is respectively arranged with lower round steel, upper round steel and lower round steel insert in corresponding coil cushion block respectively.
Tightened up by top nut after the two ends of described upper stretching screw are each passed through upper clamping piece.
Tightened up by lower nut after the two ends of described lower stretching screw are each passed through lower clamping piece.
Tightened up by perpendicular nut after the two ends of described perpendicular stretching screw are each passed through the trough rim of upper clamping piece and lower clamping piece.
The beneficial effects of the utility model are: the angle steel after welding and upper clamping piece, lower clamping piece, by upper stretching screw, lower stretching screw with after vertically pulling tight screw acting, form a whole, thus better strengthen the mechanical strength of coil.After improving process, form an overall structure, act on power on coil, can only be stressed at middle part.Transformer oil can form convection current in coil, has played the cooling effect of transformer oil to a great extent.
