Description
Technical field
The utility model belongs to power transmission and transformation field, is specifically related to a kind of forced oil-circulation air-cooled transformer with wet-curtain cooling device.
Background technology
The necessary outdoor or half outdoor installation of large-scale forced oil-circulation air-cooled transformer, during summer operation, transformer load is large, caloric value is large, and air ambient temperature is high simultaneously, and air cooling effect is poor, transformer operation oil temperature is higher, affect equipment stable operation, and coil aging speed is fast, the life-span is short.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of forced oil-circulation air-cooled transformer with wet-curtain cooling device, can effectively to transformer oil and radiating fin, lower the temperature, solve the problems such as the high oil temperature of large-scale forced oil-circulation air-cooled transformer summer operation.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of forced oil-circulation air-cooled transformer with wet-curtain cooling device, comprise transformer body, between transformer body and radiating fin, by pipeline, connect into circulation canal, pipeline between the oil-out of transformer body and the oil-in of radiating fin is provided with oil pump, between transformer body and radiating fin, be provided with wet curtain ventilated net, the top of wet curtain ventilated net is provided with spraying water pipe, below is provided with water storage tank, one end of spraying water pipe connects running water pipe, pipeline between spraying water pipe and running water pipe is provided with electromagnetically operated valve, electromagnetically operated valve is connected with thermostat, thermostat is arranged on the surface of radiating fin.
Described radiating fin one side is provided with wet curtain ventilated net, and opposite side is provided with a plurality of fans side by side.
Distance between described radiating fin and wet curtain ventilated net is 30-50mm.
The corrugated plate shape juxtaposition network structure of described wet curtain ventilated net for adopting polymer composite to make, this polymer composite be take string as base material, processes sintering form through special resin.
The utility model is owing to adopting said structure, transformer oil in transformer is by oil pump forced circulation, transformer oil flows in fin radiator, condensation fan is installed in fin radiator outside, after extracting the cooling transformer radiating fin of natural wind, externally naturally discharge, transformer oil and air are taken away transformer coil caloric value by radiating fin heat exchange, thereby ensure transformer Inside coil normal operating temperature.Simultaneously, when thermostat detects transformer radiating fin temperature over electromagnetically operated valve start-up temperature set point, electromagnetically operated valve action is opened, start spraying water pipe and spray water to wet curtain ventilated net, by the water evaporates in wet curtain ventilated net, reduce radiating fin inlet temperature, improve radiating fin cooling effect, thereby reduce transformer operation oil temperature, when radiating fin temperature is reduced to closed electromagnetic valve set point, electromagnetically operated valve action is closed, and stops spraying.By being arranged in the water storage tank of wet curtain ventilated net bottom, collect wet curtain ventilated net surface drippage moisture content, by wet curtain ventilated net self water-absorption fiber, absorb moisture content in water storage tank, realize water resources cycling and reutilization.
