Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are 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, the insulation system of oil immersed type amorphous alloy distribution transformer coil provided by the utility model,
It includes several U-shaped cardboard grooves 100, several first epoxy plates 200, several second epoxy plates 300 and several drawing spiral shells
Bar 400.
In oil immersed type amorphous alloy distribution transformer two U-shaped cardboard grooves are provided between every two neighboring coil 500
100, this two U-shaped cardboard grooves 100 are specifically horizontally disposed with successively, and U-shaped cardboard groove 100 is used to realize between two coils 500
Electric insulation.
One the first epoxy plate 200 is set in the upper end of each coil 500, one is set in the lower end of each coil 500
The side rounding angular direction of second epoxy plate 300, the first epoxy plate 200 and the second epoxy plate 300 is outside, the He of the first epoxy plate 200
Second epoxy plate 300 is used for the insulating properties for protecting the upper and lower ends of coil 500.
The first screw hole with the hole corresponding matching on upper clamping piece 600 is provided with the first epoxy plate 200, in the second epoxy
Plate 300 is provided with the second screw hole with the hole corresponding matching on lower clamping piece 700.
Screw rod 400 is drawn to sequentially pass through upper clamping piece 600, the first screw hole, the screw hole of coil 500 second and lower clamping piece 700,
So as to which upper clamping piece 600, the first epoxy plate 200, coil 500, the second epoxy plate 300 and lower clamping piece 700 are fixed as one.
By the implementation of said structure, the resistance to shorting impact capacity of coil 500 can be improved.
In addition, in order to improve steadiness, cushion block 800 is provided between the first epoxy plate 200 and upper clamping piece 600, in cushion block
