Further preferably, the arc-shaped limiting boss and the arc-shaped limiting groove of the upper cushion block and the lower cushion block are both arc-shaped and coaxial with the coil.
The utility model has the advantages that:
when the dry-type transformer cushion block device is used, the damping rubber pad of the upper cushion block is firstly bonded on the upper cushion block press-fitting platform, the damping rubber pad of the lower cushion block is bonded on the lower cushion block press-fitting platform, the upper cushion block is mounted between the upper clamping piece, the low-voltage coil and the high-voltage coil, the lower cushion block is mounted between the lower clamping piece, the low-voltage coil and the high-voltage coil, the lower cushion block is positioned through the base positioning hole and the lower clamping piece, then the low-voltage coil and the high-voltage coil are subjected to cushion-fitting positioning through the lower cushion block press-fitting platform, and the insulation cylinder is positioned through the.
The upper cushion block is positioned with the upper clamping piece through the pressing nail positioning hole, then the low-voltage coil and the high-voltage coil are pressed, adjusted and fixed through the upper cushion block pressing platform, and the insulation cylinder is fixed and limited through the upper cushion block arc-shaped limiting groove. And then the upper clamp pressing nail is pressed tightly to tightly press the upper cushion block through the upper cushion block pressing nail positioning hole, so that the low-voltage coil, the insulating cylinder and the high-voltage coil are tightly pressed and fixed.
Because the upper cushion block arc limiting boss and the upper cushion block arc limiting groove and the lower cushion block arc limiting boss and the lower cushion block arc limiting groove are of arc structures, the arc and the coil have the same axle center. The insulation distance of high-low voltage coil quality inspection just can be guaranteed to not needing too much adjustment and design margin, and convenient assembling saves man-hour, and material saving has reduced product cost and manufacturing cost, and the arc structure is good to the spacing fixed effect of coil and insulating cylinder simultaneously, and the shock pad buffering effect is good.
