Abstract
The invention discloses a wrapping insulation part for high tension coils of an oil-immersed transformer. The wrapping insulation part comprises a transformer oil tank and is characterized in that insulation devices are arranged on the high tension coils, the insulation devices are fixed to the outer sides of the high tension coils in a wrapping mode, and the insulation devices are located between the high tension coils, and between the high tension coils and the wall of the oil tank, The wrapping insulation part of the wrapping insulation structure that supporting curtains and a paperboard used on the high tension coils. Small oil gap insulation structures are formed between every two phases of high tension coils and between the high tension coils and the wall of the oil tank, and the high tension insulation level is greatly enhanced. Thus the insulation distances between the high tension coils and between the high tension coils and the wall of the oil tank can be effectively reduced, the using amount of materials of oil of the oil tank and the transformer is reduced, the wrapping insulation part of the supporting curtains and the paperboard tightly wrapping the coils increases the mechanical strength of the coils of the transformer for resisting short-circuit electric power and has the function of a guide oil channel, it is ensured that the heat dissipating capacity of the coils of the transformer is not lowered, and the temperature rising requirement is met.
Description
Technical field
The present invention relates to high-tension coil outsourcing insulation system, 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 guarantee High-Voltage Insulation level, between every two-phase high-tension coil, high-tension coil to oil tank wall between design adopt enough large insulation distance, for guaranteeing 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.
Summary of the invention
The object of this invention is to provide a kind of simple in structure, simple installation, safe, the oil-immersed transformer high-voltage coils that barrier propterty is good insulate with outsourcing.
For achieving the above object, the technical solution adopted in the present invention is: a kind of oil-immersed transformer high-voltage coils insulate with outsourcing, 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.
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 consists 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.
Preferably, described cal(l)iper is 0.5mm, and its width is consistent with stay curtain width, and its girth is less than high-tension coil outer perimeter 40 ~ 80mm.
The present invention adopts after said structure, owing to adopting, uses " stay curtain+cardboard " outsourcing insulation system on high-tension coil.Make between every two-phase high-tension coil, form small oil gap insulation system between high-tension coil and oil tank wall, greatly strengthened High-Voltage Insulation level, thereby can effectively reduce between high-tension coil, the insulation distance between high-tension coil and oil tank wall, reduced 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 guarantees transformer coil and do not reduce temperature rise and meet the demands.
