Abstract

Disclosed is a dry-type electric transformer core. The dry-type electric transformer core is composed of iron cores, clamping pieces, high-voltage windings, low-voltage windings, bolts, cushion blocks and bases, wherein the high-voltage windings are formed by stacked blocks in series. The dry-type electric transformer core is used for changing voltages of power networks.

Description

Dry-type power transformer device core

Technical field

The utility model relates to a kind of time variant voltage device of power network, specifically refers to dry-type power transformer device core.

Background technology

At present, the high pressure winding of known dry-type power transformer device core is a layer string shape, and turn-to-turn, bedding void are very little, and cooling effect is poor.

Summary of the invention

For the high pressure winding that overcomes existing dry-type power transformer device core is layer string shape, the turn-to-turn space is very little, the deficiency that cooling effect is poor; It is folded piece string shape that the utility model provides a kind of high voltage winding of dry-type power transformer device core, and turn-to-turn, folded interblock space are large, good cooling results.

The new solution that its technical problem that solves the utility model adopts is: the dry-type power transformer device core that is comprised of iron core, folder, high pressure winding, low pressure winding, bolt, cushion block, base.Described high pressure winding is folded piece string shape.

The beneficial effects of the utility model are, simple structure, easy row, and turn-to-turn, folded interblock space are large, good cooling results, have improved the operational efficiency of dry-type power transformer.
