Plate type structure is adopted for oil-oil heat exchangers. Insulating oil for transformer is utilized for oil flow system. Features are: preventing oil tank from leakage caused by high pressure borne, using insulating oil for transformer, on the safe side, complete self cooling type radiators installed on ground, noise reached to environmental protective requirement in 0 class, small quantity of investment, long service life, and low expenses for operation and maintenance.
Description
Technical field
The present invention relates to a kind of oil-oil cooling system that is used for the oil-filled transformer cooling of underground substation.
Background technology
The type of cooling of the oil-filled transformer of at present existing in the world underground substation, adopt undoubtedly: 1, water-cooling pattern (oil-filled transformer 101 '+water cooler 11 '+cooling tower 12 '); 2, the exhaust air cooling way (oil-filled transformer 101 '+forced air cooler 13 '+aiutage 14 '); 3, direct radiator mode (oil-filled transformer 101 '+radiator 103 ').
For the underground substation that is positioned at the down town, all there are the noise environmental issue in above-mentioned water-cooled and air cooling way:
As shown in Figure 1, if water-cooling pattern, its investment is high, operation and maintenance cost is high, the life-span is short, noise high (can not satisfy II class and above environmental requirement) in case, the cooling water seepage will threaten shortcomings such as transformer safe operation.
As shown in Figure 2, if the exhaust air cooling way, then exhaust noise can not satisfy II class and above environmental requirement, and its input is not economized yet.
As shown in Figure 3, if directly adopt pressure-oil tank heat spreader structures (transformer is underground, and radiator is on ground), its investment economizes most, but easily causes the fuel tank seepage to be difficult to handle, and operation risk is big.
So the existing type of cooling all should not adopt in the subway transformer of city.
Summary of the invention
A kind of oil-oil cooling system that is used for the oil-filled transformer cooling provided by the invention, by oil-oil heat exchanger cooling system is divided into two independently oily streaming systems, has avoided fuel tank to bear high pressure and caused seepage, simultaneously without cooling water, and the use transformer insulation oil is safe and reliable.The radiator floor mounted can realize complete self cooling mode, and noise can reach 0 class environmental requirement (less than 40dB).Characteristics such as also have small investment (being about water-cooled 40-50%), the life-span is long, operation and maintenance cost is low.
In order to achieve the above object, the invention provides a kind of oil-oil cooling system that is used for the oil-filled transformer cooling, comprise and be arranged on underground oil-filled transformer, pipeline connects several oil-oil heat exchangers of described oil-filled transformer, and pipeline connects several radiators of described oil-oil heat exchanger;
Described heat exchanger adopts plank frame, can improve its heat-exchange capacity, reduces the quantity of ground radiator, reaches optimal economic and cooperates;
Described oil-filled transformer and oil-oil heat exchanger constitute transformer side oil streaming system by pipeline, and described transformer side oil streaming system also comprises heat exchanger, oil pump, valve, the oil stream indicating device that pipeline connects;
