Abstract
The utility model relates to an amorphous alloy dry-type transformer, and belongs to the technical field of transformers; based on the structure of existing amorphous alloy dry-type transformer, the utility model is an improvement that an insulative component consisting of an insulative cylinder and insulative supporting strips is arranged in the gap between a low-voltage winding and a iron core to eliminate for the effect of heating and mechanical force, the low-voltage winding leads a winding to discharge towards ground, and leads to the insulative thermal breakdown of the winding; between the low-voltage winding and the iron core, only fine insulative supporting strips contacts the surface of the iron core; the cooling surface of the iron core do not affect that of the low-voltage winding at all; with simple structure and high applicability, the utility model can replace existing amorphous alloy dry-type transformers.
Description
Technical field
The utility model relates to a kind of amorphous alloy dry-type transformer, belongs to the transformer technology field.
Background technology
The structure of amorphous alloy dry-type transformer is an iron core in the middle of being, iron core is outward low pressure winding, high pressure winding successively, is up and down fixed head, has the gap between low pressure winding and the iron core, between iron core and low pressure winding, without any insulating material as skeleton and safeguard procedures.Purpose is to help heat radiation, when the non-billon dry-type transformer of this structure exists in the circuit bringing onto load, the effect of mechanical force and heat is arranged, can make the high and low pressure winding produce irregular play and thermal radiation, to cause winding to discharge over the ground and the winding insulation thermal breakdown when play is serious, accident such as finally cause that transformer burns.
Summary of the invention
The purpose of this utility model provides a kind of amorphous alloy dry-type transformer, solving existing amorphous alloy dry-type transformer exists under the effect of heat and mechanical force because of its reasons in structure, the high and low pressure winding is discharged over the ground and the winding insulation thermal breakdown, thereby the deficiency of accident such as cause that short circuit finally causes that transformer burns, realize the low pressure winding neither can play, do not influence radiating effect again, subdue the thermal radiation of winding, help improving the quality of products and useful life iron core.
The purpose of this utility model is achieved through the following technical solutions, a kind of amorphous alloy dry-type transformer comprises iron core, low pressure winding, high pressure winding that iron core is outer, last bottom plate is characterized in that being provided with axial insulation thermal insulation barriers in the gap of low pressure winding and iron core.
The thermal insulation barriers that insulate is made of the insulating stay of the heat insulation tube of the insulation of rectangular shape with the axial direction of some spaces of the heat insulation tube of insulation inwall stickup, and each insulating stay touches with iron core respectively.
Insulate heat insulation tube and insulating stay and low pressure, high pressure winding is contour.
The utility model is the improvement on existing amorphous alloy dry-type transformer architecture basics, by the insulation thermal insulation barriers that is made of heat insulation tube of insulation and insulating stay is set in the gap of low pressure winding and iron core, having stopped the low pressure winding discharges winding and the winding insulation thermal breakdown because of the effect of heat and mechanical force over the ground, between low pressure winding and iron core, have only tiny insulating stay to contact with face unshakable in one's determination, heat-delivery surface unshakable in one's determination and the heat radiation of the heat-delivery surface of low pressure winding have no effect, the utility model is simple in structure, practicality is very strong, alternative existing amorphous alloy dry-type transformer.
Description of drawings
Fig. 1 is the utility model cross section structure schematic diagram;
Among the figure, 1 iron core, 2 low pressure windings, 3 high pressure windings, the heat insulation tube of 4 insulation, 5 insulating stays.
Embodiment
Further specify the utility model in conjunction with the accompanying drawings and embodiments, the utility model is by iron core 1, low pressure winding 2, high pressure winding 3, insulation thermal insulation barriers and last bottom plate constitute, low pressure winding 2, high pressure winding 3 places outside the iron core 1 successively, the insulation thermal insulation barriers places in the gap of low pressure winding 2 and iron core 1, the thermal insulation barriers that insulate is made of the insulating stay 5 of the heat insulation tube 4 of the insulation of rectangular shape with the axial direction of some spaces of the heat insulation tube of insulation inwall stickup, each insulating stay 5 touches with iron core 1 respectively, and heat insulation tube 4 and insulating stay 5 and iron core 1 insulate, low pressure winding 2, high pressure winding 3 is contour.
