Description
Technical field
The present invention relates to transformer technology field, more particularly to a kind of a kind of air-cooled Three-phase oil immersion type for improving heat dispersion
Distribution transformer.
Background technology
Transformer be generate electricity, power and electricity consumption enterprise in visual plant, it is also at extremely crucial ground in power network
Position, is to ensure power grid security, reliable operation and people's production and the extremely important equipment of household electricity.
Oil-filled transformer is applied to power system, industrial and mining enterprises, traffic, postal and telecommunication entities, R＆D institution etc., to various height
Voltage electrical equipment, electric elements, insulating materials carry out the dielectric(al) test under power frequency or high direct voltage.Oil-filled transformer is
Make cooling medium, such as oil, oil, oil immersed water cool and forced oil-circulation etc. by oil.The effect of oil is to insulate, dissipate
Heat, elimination electric arc.
Transformer is completed a certain voltage conversion into during another voltage class, there is open circuit loss and load
Loss, therefore, it is necessarily accompanied with the generation of heat.The oil of oil-immersed type transformer plays dual parts of to insulate and radiates.Transformer
The increase of loss is proportional to 3/4 power of capacity, and oil tank of transformer cooling surface increase only with 1/2 power of capacity into
Ratio.110kV grades of oil-immersed power transformer voltage class is high, capacity is big.Thus, with the increase of transformer capacity, only
Distributing for heat just can guarantee that using the appropriate type of cooling.
In order to solve the above problems, Chinese patent CN104112567A discloses a kind of radiating oil-filled transformer high, bag
Fuel tank, fuel tank cap, high-voltage pile and the low pressure pile crown of winding and iron core are set in including, the fuel tank cap is arranged on fuel tank, and oil
The top of case lid is provided with fin, and the heat dissipation channel being connected with fuel tank is provided with the fin, forms backflow；The piling high
Head and low pressure pile crown oblique both sides for being located at fuel tank cap respectively；Drain tube is additionally provided with the top of fuel tank cap, the drain tube is highly
More than the height of heat dissipation channel in the fin in fuel tank cap, and the liquid level of the oil that radiated in fuel tank is left a blank in advance with drain tube top
Between.The invention is set up fin in conventional transformer fuel tank cap and forms heat dissipation channel, improves radiating efficiency, extends transformer
Physical life, while using drain tube carry out gas collection, exhaust etc. process.But, the technical scheme of present disclosure, Jin Jin

Logical fuel tank, the inside of the fuel tank is provided with the helical pipe that the vertical direction for taking away oil temperature is set, the helical pipe point
Lian Jie not outlet pipe and return pipe, the logical circulating path of the water tank, outlet pipe, return pipe and helical pipe composition current.On
The technical scheme of content disclosure is stated, cooling water is passed through again by the helical pipe that outlet pipe flows into bottom-up setting using water pump
Oil temperature in fuel tank is taken away acceleration radiating by return pipe reflow tank, cooling water, and temperature oil meeting elevating screw pipeline higher is certainly
Upward setting down can largely take away oil temperature, and the control of water pump can be controlled to start and closed on switch board, and increase is used
Security.But, the helical pipe that heat exchange is used in the technical scheme is placed in inside oil tank of transformer, and its mechanism is complicated,
It is difficult to realize, meanwhile, its limited sealing property requirement of oil-filled transformer is higher, and the insulating oil in fuel tank belongs to inflammable and explosive substances
