Abstract
The utility model discloses an oil-immersed paper condenser type bushing applied to electric transmission and transformation transformers with ultra-high voltage, which comprises an airside porcelain bushing, an oil porcelain piece connected with the airside porcelain bushing, a capacitance core arranged in the porcelain bushing; the upper end of the airside porcelain bushing is provided with an oil conservator and an anticorona ring. The oil-immersed paper condenser type bushing of the utility model is characterized in that the middle part of the airside porcelain bushing is a core-shaped transition, and the diameter above the middle part is less than the diameter below the middle part. The structure of the oil-immersed paper condenser type bushing of the utility model can greatly reduce the weight and volume at the upper end of the transformer bushing; therefore, while installing and operating the airside porcelain bushing, the weight of the upper part of the airside porcelain bushing is lighter than the lower part, the stability of the whole bushing at the vertical direction can be increased.
Description
Technical field
The present invention relates to a kind of extra-high voltage electric transmission and transformation transformer oil-paper condenser-type terminal.
Background technology
The extra-high voltage electric transmission and transformation transformer sleeve pipe of the above electric pressure of 1000kV, because air end insulator diameter, highly all bigger, the capacitor core insulating layer thickness of sleeve pipe is long again, the insulation processing difficulty of the manufacturing technology of air end insulator and capacitor core is all bigger, therefore cost is higher, has only the minority developed countries to develop at present and is applicable to extra-high voltage electric transmission and transformation transformer sleeve pipe.As renowned companies such as electroceramics factory of the former full Soviet Union of Russia, German HSP, Britain's Reynolds that, Japanese NGK, Siemens, but because its product separately all has bigger difference on profile and internal structure, and some product can not be applicable to the actual needs that the extra-high voltage grid of China is built.
Summary of the invention
The transformer that the technical problem to be solved in the present invention provides a kind of hundred Wan Fu transformer stations is with oil-paper capacitive transformer sleeve pipe, have stablize vertically that sexual type is good, the characteristics of mechanical connection performance and excellent earthquake resistance.
For reaching above purpose, the present invention takes following technical scheme to be achieved:
A kind of extra-high voltage electric transmission and transformation transformer oil-paper condenser-type terminal, comprise the capacitor core in porcelain spare in air end insulator and the connected oil, the insulator, described air end insulator upper end is provided with conservator and anticorona ring, it is characterized in that, described air end insulator middle part is a tapering transition, and the diameter of the above insulator in middle part is less than the diameter of the following insulator in middle part.
In the such scheme, porcelain spare connects a mounting flange in the described oil, described air end insulator two ends are respectively equipped with first mucilage binding flange that is connected with conservator and the second mucilage binding flange that is connected with mounting flange, adopt the current-carrying structure of rod-pulling type contact tube in the middle of the described capacitor core; In the oil between porcelain spare and the mounting flange be connected to bolt and spring is connected; Described pull bar porcelain porcelain spare in whole air end insulator and the oil.
The utility model makes the capacitor core volume reduce owing to optimized the design of sleeve pipe main insulation capacitor core, tapering transition can be adopted in air end insulator middle part like this, the diameter of the above insulator in middle part is less than the diameter of the following insulator in middle part, thereby reduced the weight and volume of bushing shell for transformer upper end greatly, like this when air end insulator installation and operation, the weight of its upper end is lighter than the weight of lower end, has obviously increased the vertical stability of whole sleeve pipe.Cooperate mucilage binding flange and mounting flange simultaneously, adopt bolt and spring to realize that the brute force of insulator in air end insulator and the oil connects, and has further strengthened the mechanical connection performance and the anti-seismic performance of sleeve pipe.
