Abstract
The utility model discloses the outsourcing of a kind of oil-immersed transformer high-voltage coils and insulate, comprise: and oil tank of transformer, it is characterized in that: on described high-tension coil, be provided with seal, this seal holds and is fixed on high-tension coil outside, its position is between high-tension coil, and between high-tension coil and oil tank wall.The utility model adopts and on high-tension coil, uses " stay curtain+cardboard " outsourcing insulation system.Make between every two-phase high-tension coil, form small oil gap insulation system between high-tension coil and oil tank wall, greatly strengthen High-Voltage Insulation level, thereby can effectively reduce between high-tension coil, insulation distance between high-tension coil and oil tank wall, reduce the material usage of fuel tank and transformer oil, " stay curtain+cardboard " outsourcing insulation of hard-pressed bale coil has not only increased the electrodynamic mechanical strength of transformer coil Short Circuit withstand, and has heat-sinking capability that guide oil channel effect ensures transformer coil and do not reduce temperature rise and meet the demands.
Description
Technical field
The utility model relates to high-tension coil outsourcing insulation system, and especially a kind of oil-immersed transformer high-voltage coils insulate with outsourcing.
Background technology
The oil-filled transformer of the 20-35kV of traditional mode of production, as the high-tension coil of transformer exterior loop in order to ensure High-Voltage Insulation level, between every two-phase high-tension coil, high-tension coil to oil tank wall between design adopt enough large insulation distances, for ensureing the design of High-Voltage Insulation performance, can be difficult to reduce the material usage of fuel tank and transformer oil and reduce product cost like this.
Utility model content
The purpose of this utility model is to provide a kind of simple in structure, simple installation, and safe, the oil-immersed transformer high-voltage coils that barrier propterty is good insulate with outsourcing.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of oil-immersed transformer high-voltage coils insulate with outsourcing, comprise: high-tension coil and oil tank of transformer, it is characterized in that: on described high-tension coil, be provided with seal, this seal holds and is fixed on high-tension coil outside, its position is between high-tension coil, and between high-tension coil and oil tank wall.
Preferably, described seal adopts half-dried without latitude adhesive tape, and shrink belt from top to bottom by seal tighten on high-tension coil.
Preferably, described seal is made up of cardboard, stay curtain, and the stay curtain rule of some quantity sticks on cardboard, and this stay curtain is parallel to each other and distance equates.
Preferably, described stay curtain adopts cardboard hot pressing to form, and its thickness is 5 ~ 10mm, and its width is 8 ~ 12mm, and its length is less than coil height 2 ~ 6mm.
