Specific implementation mode
In order to make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
Referring to Fig. 1 to Fig. 4, high-performance oil immersed type amorphous transformer coil resistance to shorting structure provided by the utility model,
Including several insulating barriers 100 and several fixing devices 200.
One insulating barrier 100, insulation are set between the two neighboring coil group 300 of oil immersed type amorphous transformer coil
Partition board 100 and can be protected to coil group 300 for ensureing the insulation performance between two coil groups 300 so that coil
Group 300 is hardly damaged in banding fixed.
Insulating barrier 100 is specially rectangle comprising a rubber slab 110, in rubber slab 110 and side coil group 300
The first resistance to oil reservoir 120 and the first insulating layer 130 are equipped on contact surface successively, in connecing for rubber slab 110 and other side coil group 300
The second resistance to oil reservoir 140 and second insulating layer 150 are equipped in contacting surface successively.
First insulating layer 130 is used to improve the insulating properties between rubber slab 110 and the coil group 300 of side, and second is exhausted
Edge layer 150 is for improving the insulating properties between rubber slab 110 and the coil group 300 of the other side.
First resistance to oil reservoir 120 is for improving the oil resistivity between rubber slab 110 and the coil group 300 of side and second
Resistance to oil reservoir 140 is for improving the oil resistivity between rubber slab 110 and the coil group 300 of the other side.
Rubber slab 110 is the coil group for being supported for the coil group 300 to both sides, and working as 110 both sides of rubber slab
300 when fixed, and rubber slab 110 can be that coil group 300 provides buffering, to prevent damaging coil group 300 by pressure.
Fixing device 200 include two layers of fixed bed, every layer of fixed bed by binding strap 210 along two coil groups 300 under
And upper banding fixed forms.
