Abstract
The transformer oil cooler that the utility model relates to use under a kind of environment suitable for low-temperature working.Transformer oil is extracted out using pump and is heated by cooling device, further according to environment temperature, automatically switch suitable heat exchanger and oil is cooled to suitable temperature, guarantees to be able to satisfy suitable temperature under the different environment temperature of transformer oil, improve the scope of application of the transformer oil.
Description
Technical field
The utility model relates to a kind of cooling devices, and in particular to the transformation used under a kind of environment suitable for low-temperature working
Device oil cooler.
Background technique
45# transformer oil is a kind of transformer oil that freezing point is -45 DEG C, and the medium is used only in environment temperature at home
In the oil cooling device of -10 DEG C of degree or more.When environment temperature is down to -20 DEG C or less, 45# transformer viscosity oil can be in the song that raises up
The increase of wire type, transformer oil run unsmooth in the duct, influence service life and the cooling effect of oil pump.
Summary of the invention
For the limitation used for overcoming 45# transformer oil, ensure that oil cooling device -40 DEG C~55 DEG C of environment temperature just
Often work, the purpose of this utility model is to provide the transformer oil coolers used under a kind of low-temperature working environment.
The technical solution that the utility model is taken is：
Transformer oil cooling device, including cooling box are used under low-temperature working environment, and electric cabinet, cabinet are installed in cabinet
Blower is installed on interior side side plate, is equipped with side by side in cabinet close to blower side and just imitates heat exchanger and high-performance heat exchanger, case
Oil pump and electrical heated pipings are installed in vivo, the oil pump input port connects oil tank of transformer through pipeline, and oil pump delivery outlet is through pipe
Road connects electric heating tube, and the delivery outlet of electric heating tube is separately connected the defeated of just effect heat exchanger and high-performance heat exchanger through two bypass lines
Enter end, be serially connected with solenoid valve respectively on two bypass lines, just imitates heat exchanger with the output end of high-performance heat exchanger and connect transformer oil
Case.
Further, the just effect heat exchanger is pipe heat exchanger, is cased with fin on the heat exchanger tube of pipe heat exchanger.
Further, the high-performance heat exchanger is plate heat exchanger.
Still further, more cooling water pipes can be installed in high-performance heat exchanger, there is water pump to be passed through circulation in cooling water pipe cold
But water.
After taking above technical scheme, the beneficial effects of the utility model are：This cooling device utilizes pump by transformer oil
Extraction heating automatically switches suitable heat exchanger for oil and is cooled to suitable temperature, guarantee transformer oil further according to environment temperature
It is able to satisfy suitable temperature under different environment temperatures, improves the scope of application of the transformer oil.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Specific embodiment of the present utility model is further described below in conjunction with attached drawing：
As shown, using transformer oil cooling device, including cooling box under low-temperature working environment, electricity is installed in cabinet
Case is controlled, electric cabinet is provided with touch display screen, and side side plate interior sides are equipped with blower 1, close 1 side of blower in cabinet in cabinet
Just effect heat exchanger 2 and high-performance heat exchanger 3 are installed side by side, heat exchanger 2 is just imitated and high-performance heat exchanger 2 passes through the air-cooled heat exchange of blower 1；
Oil pump 4 and electrical heated pipings 5 be installed, oil pump 4 extracts transformer oil from oil tank of transformer 6, and by transformer oil in cabinet
It is sent into electric heating tube 5 and heats, the oil in electric heating tube 5 after heat temperature raising can respectively enter just effect heat exchange by two bypass lines
Exchange heat cooling in device 2 and high-performance heat exchanger 3, and just imitating heat exchanger is pipe heat exchanger, is cased with wing on the heat exchanger tube of pipe heat exchanger
Piece.High-performance heat exchanger is plate heat exchanger.Solenoid valve 7 is serially connected on two bypass lines respectively, solenoid valve is under electric cabinet control
Work opens the solenoid valve of just effect heat exchanger 2 when environment temperature is lower than -20 DEG C, and it is small size to transformer oil just to imitate heat exchanger 2
Cooling, guaranteeing can be in suitable temperature when it returns to fuel tank；When environment temperature is higher than -20 DEG C, the corresponding electricity of high-performance heat exchanger 3
Magnet valve is opened, and is carried out significantly heat exchange to transformer oil by high-performance heat exchanger 3 and is cooled down, guaranteeing can be suitable when it returns to fuel tank
Temperature.Just the transformer oil after the heat exchange of effect heat exchanger 2 or high-performance heat exchanger 3 is circulated back to oil tank of transformer 6.
More cooling water pipes can be installed in plate heat exchanger, water pump 8 extracts cooling water from water tank 9 and is passed through cooling water pipe,
When the device is due to ship, it can choose and be passed through the mode of seawater in cooling water pipe and exchange heat, the heat exchange mode is as supplement
Or exchange heat simultaneously with air-cooled, improve heat transfer effect.When seawater is cooling, power consumption and noise are reduced.
