Description

The structure of high-impedance transformer built-in reactor
Affiliated technical field:
The present invention relates to a kind of structure of high-impedance transformer built-in reactor, belong to technical field of transformer manufacturing.
Background technology:
For electrical network, safe operation is vital, transformer is as the vitals in the electrical network, the size of its short-circuit impedance decision transformer change in voltage and short circuit current under loading condition, therefore in order to limit the line voltage regulation and to reduce short circuit current, a lot of customer requirements provide high-impedance transformer, again because of realizing the desired impedance voltage of user by adjusting transformer main insulation, so increased subsidiary reactor at transformer one end, caused the structure of reactor and be fixed into problem demanding prompt solution.
Summary of the invention:
The object of the invention provides a kind of structure of high-impedance transformer built-in reactor, and is safe and reliable, and the guarantee transformation is normally moved, and solves the problems referred to above that exist in the background technology.
Technical scheme of the present invention is:
The structure of high-impedance transformer built-in reactor comprises main body folder, fagging, pressing plate, upper clamping piece, cardboard cylinder, reactor winding, screw rod, supporting plate, copper sheet, lower clamping piece, pad pin, the air core reactor internal coil diameter is by the cardboard cylinder stretching, the pressing plate above the reactor winding is inserted in the cardboard cylinder upper end, and supporting plate is inserted in the bottom; In pressing plate bottom and supporting plate top is iron core of electric reactor, and screw rod is fixed into an integral body with coil, supporting plate, pressing plate and top and the bottom iron core, is fixed together by bolt and transformer body folder again; The iron core of electric reactor lamination links to each other with lower clamping piece by copper sheet, and pad pin and fagging link together by screw rod, and upper and lower folder is connected with screw rod respectively, is connected with adjacent fagging, main body folder.
Iron core of electric reactor is to form rectangular structure by silicon steel sheet is folded, by epoxy resin folder and lamination is sticked into an integral body, uses the binding strap colligation again, is placed between pressing plate, the supporting plate.
Between fagging and main body folder, be provided with the ground connection connecting line, guarantee that iron core and hardware thereof must ground connection.
The present invention is iron core of electric reactor in order to reduce leakage flux in pressing plate bottom and supporting plate top, is fixed into an integral body by screw rod, and is fixed together with the transformer body folder, the vibrations and the noise that have produced when having reduced the reactor operation effectively.Because iron core of electric reactor and hardware thereof have different current potentials under the electric field action of coil, different again with the fuel tank current potential.Though potential difference is little between them, also will continue discharge by very little insulation distance.Discharge makes oil decomposition on the one hand, can't confirm on the one hand whether transformer is normal in test and operating state, so iron core and the necessary ground connection of hardware thereof, the present invention has adopted simple and clear grounding system, and the iron core of electric reactor lamination links to each other with its folder by copper sheet, and pad pin and fagging link together by the stainless steel screw rod, folder from top to bottom is connected with the stainless steel screw rod respectively, adjacent then last fagging links to each other, and is connected with the transformer body folder at last, has guaranteed one point earth.
That the present invention has is rational in infrastructure, safe and reliable, ensure characteristics such as the normal operation of transformation.
Description of drawings:
Fig. 1 is an embodiment of the invention structural representation;
Fig. 2 is the end view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
Among the figure: 1-main body folder; 2-ground connection connecting line; The 3-fagging; The 4-pressing plate; The 5-upper clamping piece; The 6-cardboard cylinder; The 7-reactor winding; The 8-screw rod; The 9-supporting plate; The 10-copper sheet; The 12-lower clamping piece; 13-pad pin.
Embodiment:
Below in conjunction with accompanying drawing, the invention will be further described by embodiment.
In an embodiment, air core reactor coil 7 internal diameters are by cardboard cylinder 6 stretchings, and the pressing plate 4 above the coil is inserted in cardboard cylinder 6 upper ends, and supporting plate 9 is inserted in the bottom; In order to reduce leakage flux, in pressing plate 4 bottoms and supporting plate 9 tops is iron core of electric reactor, and iron core of electric reactor is to form rectangular structure by silicon steel sheet is folded, by epoxy resin folder and lamination is sticked into an integral body, use the binding strap colligation again, be placed between pressing plate, the supporting plate; With screw rod 8 reactor winding 7, supporting plate 9, pressing plate 4 and top and the bottom iron core are fixed into an integral body then, are fixed together by bolt and transformer body folder 1 again, the vibrations and the noise that have produced when having reduced the reactor operation effectively.Because iron core of electric reactor and hardware thereof have different current potentials under the electric field action of coil, different again with the fuel tank current potential.Though potential difference is little between them, also will continue discharge by very little insulation distance.Discharge makes oil decomposition on the one hand, can't confirm on the one hand whether transformer is normal in test and operating state, so iron core and the necessary ground connection of hardware thereof.Present embodiment has adopted simple and clear grounding system, the iron core of electric reactor lamination links to each other with lower clamping piece 12 by copper sheet 10, pad pin 13 and fagging 3 link together by screw rod, upper clamping piece 5, lower clamping piece 12 are connected with the stainless steel screw rod respectively, adjacent then fagging 3 links to each other, be connected with transformer body folder 1 at last, guaranteed one point earth.Between fagging 3 and main body folder 1, be provided with ground connection connecting line 2, guarantee that iron core and hardware thereof must ground connection.
