Embodiment
For further understanding technology contents of the present utility model, characteristics and effect, enumerate following example now, and conjunction with figs. is described in detail as follows:
Embodiment 1
With reference to accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5.
The used in nuclear power station dry-type transformer comprises support, iron core 1, coil, support fixed installation iron core 1, equipped low-voltage coil 8 in iron core 1 outside and high-tension coil 7.The epoxy resin coil of cast is provided with air flue 9.2 of its upper clamping piece 13 and lower clamping pieces are supported by channel-section steel 3, use bolt.Between lower clamping piece 2 and the footing 5 base plate 4 is housed, base plate 4 usefulness bolts and lower clamping piece 2 and footing 5 are fixed together.In aggregates between lower clamping piece 2, base plate 4, iron core 1 and the footing 5 with epoxy resin 6 cast.
Between dry-type transformer iron core 1 and outside transformation coil 7 supporting fastening pieces 10 are housed, supporting fastening piece 10 is installed for entire body, and its length and iron core and transformation coil height are complementary.Supporting fastening piece is a plank frame, two-layer epoxy resin board 11 therebetween one deck silica gel backing plates 12.
Assembling process: use the other screw rod of channel-section steel replacement with high-low pressure lower clamping piece same model, use bolt, cancellation pad foot pad piece adds a base plate 4 and uses bolt all around between footing 5 and high-low pressure lower clamping piece, all bolt junctions are all with the glass cement sealing, to prevent seepage of resin.After the cast, iron core 1, high-low pressure lower clamping piece 2, base plate 4, channel-section steel 3 constitute the cell body of a sealing, carry out resin-cast again, make folder, footing, iron core become as a whole, relative motion does not take place in each parts in vibrations, improves whole mechanical strength, guarantees the anti-seismic performance of transformer.
The low-voltage coil stretching adopts the middle structure that adds one deck silicagel pad of two-layer epoxy resin board, and is bonding each other firm.Select the epoxy resin board 11 and the silica gel backing plate 12 of suitable thickness during installation according to the gap length between iron core and the low-voltage coil, both can guarantee the intensity of coil stretching, can play the effect of damping simultaneously again.
