Description

A kind of intelligent three-phase oil immersion-type distribution transformer
Technical field
The utility model is related to transformer technology field, more particularly to a kind of raising heat dispersion, and being capable of automatic detection Oil level, a kind of intelligent three-phase oil immersion-type distribution transformer of automatic oiling.
Background technology
Transformer is the visual plant in generating, power supply and electricity consumption enterprise, and 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 insulation, dissipated Heat, elimination electric arc.
Transformer complete by a certain voltage conversion into another voltage class during, there is open circuit loss and load Loss, therefore, is necessarily accompanied with the generation of heat.The oil of oil-immersed type transformer plays dual parts of insulating and radiated.Transformer The increase of loss is proportional to 3/4 power of capacity, and the increase of oil tank of transformer cooling surface only with 1/2 power of capacity into Ratio.110kV grades of oil-immersed power transformer voltage class are 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 high radiating oil-filled transformer, 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 provided with the heat dissipation channel being connected with fuel tank in fin, the fin, forms backflow;The high piling Head and low pressure pile crown oblique both sides for being located at fuel tank cap respectively;Drain tube, the drain tube height are additionally provided with the top of fuel tank cap More than the height of heat dissipation channel in the fin in fuel tank cap, and the liquid level for the oil that radiated in fuel tank is left a blank in advance with drain tube top Between.Fin formation heat dissipation channel is set up in the invention in conventional transformer fuel tank cap, is improved radiating efficiency, is extended transformer Physical life, handled while utilizing drain tube to carry out gas collection, exhaust etc..But, the technical scheme of present disclosure, Jin Jin Fin is set in fuel tank cap, and therefore, its heat dispersion is not good.
And for example Chinese patent CN204242762U discloses a kind of water circulation type triangle volume iron transformer, including fuel tank, It is characterized in that:The fuel tank is connected with water circulation mechanism, and the water circulation mechanism includes water tank, and the inside of the water tank is provided with water Pump, the water tank is connected with outlet pipe and return pipe, and the outlet pipe is connected to water pump, and the outlet pipe connects respectively with return pipe Logical fuel tank, the inside of the fuel tank is provided with the helical pipe that the vertical direction for being used for taking away oil temperature is set, the helical pipe point Lian Jie not outlet pipe and return pipe, the water tank, outlet pipe, return pipe and the logical circulating path of helical pipe composition current.On The technical scheme of content disclosure is stated, is passed through the helical pipe that cooling water flows into bottom-up setting by outlet pipe again using water pump Oil temperature in fuel tank is taken away acceleration radiating by return pipe reflow tank, cooling water, and the higher oil meeting elevating screw pipeline of temperature is certainly Upward setting can largely take away oil temperature down, and the control of water pump can be controlled to start with closing on switch board, and increase is used Security.But, the helical pipe in the technical scheme for heat exchange is placed in inside oil tank of transformer, and its mechanism is complicated, It is difficult to realize, meanwhile, its limited sealing property of oil-filled transformer requires higher, and the insulating oil in fuel tank belongs to inflammable and explosive substances , easily there is potential safety hazard if seal approach is not carried out in matter.
