Description
Technical field
The invention belongs to electrical technology field, relate to transformer, be specifically related to a kind of transformer with branch box structure.
Background technology
For big capacity, high voltage transformer, its product structure is quite complicated.On the one hand higher or the pressure regulation tap position is more when voltage, perhaps during the insulation level extra-high-speed of transformer itself, the lead-in wire layout can be difficult or greater risk is arranged.On the other hand, because the capacity super large, the hauled weight of product and size are approaching even surpass actual transport capacity, and the cost of transportation of product is very big, is the transportation that guarantees product, also may need to reduce the design margin of product, increases the product operation risk.Therefore reducing the hauled weight and the size of transformer body, product structure is simplified, is the important topic when previous worth research.
Summary of the invention
At above-mentioned big capacity, high voltage transformer the deficiencies in the prior art part, the invention provides a kind of transformer with branch box structure.
The present invention is applicable to single-phase or three-phase transformer.Transformer by present technique design has two parts, and a part is the main part of transformer, and another part is the pressure regulation part of transformer, and two parts utilize cable or bus to link together by outlet sleeve pipe separately.The position that pressure regulation becomes can be arranged in the two ends of high-pressure side, low-pressure side or the main transformer of transformer body according to the actual needs that power plant arranges.Voltage regulating mode can adopt on-load voltage regulation or non-excitation pressure adjustment.Be applicable to three-winding transformer, autotransformer or generator transformer.Pressure regulation position and mode are according to the actual requirement decision of transformer, and for example neutral point pressure regulation is pressed during middle line ball end is transferred, and the high-pressure series coil end is heightened pressure: excitation mode can be selected according to the actual requirement and the characteristic of transformer, comprises that excitatory, the middle pressure of low pressure is excitatory.The pressure regulation position is applicable to the terminal pressure regulation of line end pressure regulation, neutral point pressure regulation or autotransformer series coil.
The branch mailbox structure transformer has two parts, a part is the main part of transformer, another part is that the pressure regulation of transformer becomes part, main body becomes the structure that partly possesses in the isolated operation of normal rating tap, comprises main body iron core, main coil (comprising high-tension coil, low-voltage coil, intermediate voltage winding), main body fuel tank, main body lead-in wire, main casing body; It also is to draw with sleeve pipe that the pressure regulation change becomes the same with main body, pressure regulation becomes part and comprises that pressure regulation becomes iron core, pressure regulation modified line circle (comprising magnetizing coil, voltage regulation coil), pressure regulation change fuel tank, tap changer, pressure regulation change sleeve pipe, aerial lug links together between main body change and the flexible mistake of pressure regulation two parts, line can adopt cable, copper bar or aluminium row, and tie point is at two parts outlet sleeve pipe separately.Integral body becomes corresponding sleeve pipe with needing while the main consuming body and pressure regulation being connected of transmission system, and the binding post changing-over that will be connected on during the main body isolated operation on the pressure regulation change sleeve pipe gets final product on the main body respective sleeve.Main body becomes the positioned opposite that becomes with pressure regulation can take different arrangements, can be arranged at main body change high-pressure side for pressure regulation becomes; Or the pressure regulation change is arranged at main body change low-pressure side; Or the pressure regulation change is arranged at main body change right side; Or the pressure regulation change is arranged at main body change left side.
Voltage regulating mode can adopt on-load voltage regulation or non-excitation pressure adjustment.The pressure regulation position is applicable to line end pressure regulation or neutral point pressure regulation, is applicable to the terminal pressure regulation of autotransformer series coil.The voltage regulation coil that pressure regulation becomes can adopt different excitation modes to realize pressure regulation, and according to the difference of pressure regulation position, the whole wiring of transformer can be taked the various modes of connection simultaneously.
The present invention is applicable to three-winding transformer, autotransformer or generator transformer.The big capacity of this new band pressure regulation, the product design mode and the structure of high voltage transformer connect and can be used as a complete transformer after the combination and use, and also main body can be used separately.This technology makes the transformer general internal simple in structure, has improved reliability of products; The outer limit of maximum transportation of transformer is reduced, and maximum hauled weight reduces, and makes things convenient for Product transport; And make product reformation easy.Compare with conventional structure, adopt and divide the advantage of box structure to be: 1) internal structure of transformer body is simple, the arrangement of convenient lead-in wire and coil, product reliability height; 2) can reduce the transportation clearance and the weight of transformer body, reduce the cost of transportation of high-power transformer; 3) have shunting switch because pressure regulation becomes, it is more to go between, and the probability that breaks down is bigger, in case pressure regulation becomes the outlet fault, the pressure regulation change can be cut out maintenance, transform, and main transformer can specified tap continue independent operating; 4) along with the needs of electricity consumption can be transformed separately the pressure regulation change, change No-load changer into on-load voltage regulation, or change on-load voltage regulation into No-load changer, perhaps change pressure regulation progression, all need not relate to main transformer and change.
