The utility model provides a kind of 3-D triangle open mouth coiling dry-type transformer unshakable in one's determination.The core construction of this transformer is three-dimensional three-phase opening rewinding material, by cross-ventilated form, transformer is dispelled the heat between high and low pressure coil, high and low pressure coil adopts special epoxy resin pouring type coil simultaneously, transformer anti-sudden short circuit ability greatly can be strengthened in normal operation, thus improve product quality, and very energy-conserving and environment-protective.
The technical scheme adopted is:
A kind of 3-D triangle open mouth coiling dry-type transformer unshakable in one's determination, comprise iron core, upper clamping piece, lower clamping piece, low pressure builds coil, high pressure builds coil, iron core is that 3-D triangle open mouth coiling is unshakable in one's determination, formed by three identical single-phase assembling combination unshakable in one's determination, fracture site is arranged on the top of iron core column.
Upper clamping piece is fixed on upper yoke unshakable in one's determination by the other screw rod that draws, lower clamping piece is fixed on lower yoke unshakable in one's determination by the other screw rod that draws, upper clamping piece and lower clamping piece are fixed dress by lateral bracing strut, low pressure builds mounting coil on core limb, high pressure builds mounting coil outside low-voltage coil, high pressure is built coil and low pressure and is built between coil and have certain air gap, high pressure is built coil outermost layer zone line and is dispersed with a point contact point, different point contact points is connected and fixed by brace, the leading-out terminal that A phase low pressure builds coil is welded on copper bar, at B, the top of C phase side is drawn, copper bar is fixed on upper clamping piece by insulated terminal, the leading-out terminal that B phase low pressure builds coil is welded on copper bar, at B, the top of C phase side is drawn, copper bar is fixed on upper clamping piece by insulated terminal, the leading-out terminal weldering that C phase low pressure builds coil is directly drawn through insulated terminal and is fixed on upper clamping piece, A phase, B phase, the leading-out terminal that C phase low pressure builds coil is welded on copper bar, o coupling goes out copper bar and is welded on copper bar, o coupling copper comes B, the top of C phase side is drawn, o coupling goes out copper bar and is fixed on upper clamping piece by insulated terminal, the extraction order of low-pressure line-outgoing row is followed successively by o, a, b, c, the leading-out terminal of A phase coil is connected by wire with the tail end of C phase coil, the leading-out terminal of B phase coil is connected by wire with the tail end of A phase coil, the leading-out terminal of C phase coil is connected by wire with the tail end of B phase coil, the lead-out wire of three-phase high voltage coil leading-out terminal is fixed on wooden insulation groove, wooden insulation groove is fixed on upper clamping piece, transformer whole is fixed on channel-section steel, and cooling blower is fixed on the rear and front end of channel-section steel.
Beneficial effect is, the more conventional dry-type transformer energy-saving effect of this dry-type transformer is more outstanding, because high and low pressure coil have employed special cast-type structure, make the total quality of product very good, in the normal operation of transformer, anti-sudden short circuit ability obtains very large reinforcement.
