Abstract
The utility model provides a resin insulating dry-type transformer for metalclad withdraw switchgear, wherein the main technical characteristics are that an iron core column is in a rectangular shape, a high and low voltage combined type winding is wholly poured into a rectangular shape, an upper clamp and a lower clamp are tensed through a draw plate, and a transformer is clamped through the upper clamp and the lower clamp for enabling the transformer to form a firm whole. The resin insulating dry-type transformer for metalclad withdraw switchgear has the advantages of small volume, light weight, low loss, good damp-proof performance, environment protection, safety and the like.
Description
Technical field:
The utility model relates to a kind of dry-type transformer, particularly a kind of resin insulating dry type transformer.
Background technology:
Present existing open type dry-type transformer, iron core are sheared closed assembly for the grain orientation cold-reduced silicon sheet and are become multistage circle, and the high-low pressure winding is circular, and the dry-type transformer volume of this class formation is bigger, in the mid-cabinet of can't packing into.
Summary of the invention:
The purpose of this utility model is for solving the deficiencies in the prior art, a kind of mid-cabinet resin insulating dry type transformer is provided, this transformer adopting brand new, and its volume is little, in light weight, in can conveniently pack into mid-cabinet and the standard high-voltage cabinet.
For achieving the above object, the utility model adopts following technical scheme:
Mid-cabinet resin insulating dry type transformer, comprise three pillar type rectangle iron core, high-low pressure combined type rectangular winding, arm-tie, folder etc., it is characterized in that, iron core column is a rectangle, the integrated poured one-tenth rectangle of high-low pressure composite type winding, by arm-tie folder from top to bottom is strained, by folder from top to bottom transformer is clamped and make firm integral body of transformer formation.
The three pillar type rectangle iron core adopts high magnetic conduction crystal grain cold-rolled orientation silicon steel sheet, and stem stem repeatedly amasss into rectangle, adopts H class F insulation band to tie up and rolls, and the surface adopts solventfree resin to apply.
High-low pressure combined type rectangular winding high-pressure section is a segmented layered structure, is divided into the 3-9 section, adopts the coiling of QZY-180 polyester imines enamelled wire, low-pressure section is a layered structure, be divided into the 2-5 layer, adopt the coiling of D711 non woven fabric envelope curve, the independent coiling of high-low pressure, integral assembling, integrated poured.
Arm-tie is the machine-shaping of Q235 hot rolled steel plate, and its sheet metal thickness is δ=6-10mm.
The beneficial effects of the utility model are:
One, effectively reduces no-load loss, and dwindled the centre-to-centre spacing of iron core column greatly, reduce core volume.
Two, improve the inner field intensity of winding, improve shock resistance, and can reduce the transformer overall volume.
Three, improve the transformer overall mechanical strength.Have that simple and reasonable, anti-short circuit capability is strong, good electric property, volume are little, in light weight, low-loss, low noise advantage.
