Description
Technical field
This utility model is related to dry-type transformer and makes field.
Background technology
Its electromagnetic principle of dry-type transformer is just the same with traditional oil-filled transformer. but on insulation system, both are then
There is huge difference. at present in 10kV epoxy cast dry transformer manufacture processes, the electromagnetism intensity in the air of air channel exceedes
During certain value, between high-tension coil and low-voltage coil and between low-voltage coil and iron core, insulating barrier is just must be designed with, it is existing
Insulating barrier make complicated, cost of manufacture is higher, has much room for improvement.
Utility model content
This utility model is directed to the deficiencies in the prior art, there is provided a kind of simple structure, is easy to make, effectively reduces air channel
Distance and diminution machine volume. while playing reduction Zao Yin improves radiating condition, particularly ensure that test industrial frequency withstand voltage is high
To it is low low generation of discharging over the ground 10kV epoxy cast dry transformers.
For realizing this utility model purpose, there is provided technical scheme below：10kV epoxy cast dry transformers, including more
Individual silicon steel sheet stack into iron core, the iron core is coaxially disposed high-tension coil and low-voltage coil；The low-voltage coil is located at high-voltage line
Circle inner side, constitutes air channel between high-tension coil and low-voltage coil, high-tension coil inner ring is provided with the first insulating cylinder, covers on low-voltage coil
The second insulating cylinder is provided with, the 3rd insulating cylinder between low-voltage coil and iron core, is provided with, air channel is provided centrally with the 4th insulating cylinder, will
Air channel is separated into two, and four insulating cylinders are formed more than the bent overlap joint of the compound mylar coiled sheet of 1.5mm by thickness, four insulation
The gluing knot of coated by special in the range of cylinder bond end 60mm, special gelatin are propanoic acid olefine resin.
Preferably, insulating cylinder is formed by the bent overlap joint of compound mylar coiled sheet, apply in the range of insulating cylinder bond end 60mm
Cover special gelatin bonding.
Preferably, special gelatin is propanoic acid olefine resin.
A kind of insulating cylinder manufacture method of 10kV epoxy cast dry transformers, it is characterised in that thickness is more than into 1.5mm
Compound mylar plate, according to different specifications and models steel one layer of mould garden side face upper measurement, being tensed with tightener makes
Compound mylar is smooth with punching block to be close to, and is put into electric oven together with steel mold and is warming up to 130 degree of insulations 3 hours, natural
It is cooled to.
This utility model beneficial effect：This utility model simple structure, is easy to make, and effectively reduces air channel distance and reduces
Machine volume. while playing reduction Zao Yin improves radiating condition, particularly ensure that test industrial frequency withstand voltage is high low to Di right
Ground electric discharge is produced.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Embodiment 1：10kV epoxy cast dry transformers, including multiple silicon steel sheet stacks into iron core 1, the iron core 1 is same

Air channel 4 is constituted between 3, and 2 inner ring of high-tension coil is provided with the first insulating cylinder 5, and on low-voltage coil 4, set is provided with the second insulating cylinder 5, low
The 3rd insulating cylinder 5 is provided between line ball circle 3 and iron core 1, and air channel 4 is provided centrally with the 4th insulating cylinder 5, and air channel 4 is separated into two
Individual, four insulating cylinders 5 are formed more than the bent overlap joint of the compound mylar coiled sheet of 1.5mm by thickness, four 5 bond ends of insulating cylinder
The gluing knot of coated by special in the range of 60mm.Special gelatin is propanoic acid olefine resin.
Embodiment 2：A kind of insulating cylinder manufacture method of 10kV epoxy cast dry transformers, by thickness more than 1.5mm's
Compound mylar plate, according to different specifications and models steel one layer of mould garden side face upper measurement, tensed with tightener make it is multiple
Close that mylar is smooth with punching block is close to, electric oven is put into together with steel mold and is warming up to 130 degree of insulations 3 hours, it is naturally cold
But into.
Test by finished product is every, industrial frequency withstand voltage drawn game can high-volume meet every electric property of its product, in reality
Mylar is combined in the batch production of border and greatly facilitates the manufacturing, make flexible overall economic efficiency very notable.
