The utility model discloses changed the cooling method of transformer, the radiating effect is good, has promoted the serviceability between the transformer megathermal period, the water pump is set for the period at the timer and is opened, avoids the waste of water resource.
Description
Technical field
This utility model relates to a kind of field of electrical equipment, is specifically related to the Water spray heat abstractor of a kind of oil immersed self cooled transformer.
Background technology
Current oil immersed self cooled transformer main transformer both sides are respectively arranged with 8 to 10 group fin, fan-free.Transformator produces substantial amounts of heat when running, and is cooled down by the insulating oil in transformer body fuel tank, it is ensured that Transformer Winding temperature is less than allowing temperature.But the cooling capacity of oil immersed self cooled transformer oil is by large-area fin auto-radiating, during summer high load capacity, because of by external environment influence, cooling capacity is poor, so when ambient temperature more than 30 degree, when main transformer tape splicing load is to rated load 70%, main transformer temperature rise will exceed transformator and dispatch from the factory permissible value, greatly limit the main transformer tape splicing ability of load boom period.The main transformer of plant stand heavier to load, will be limited by main transformer temperature rise, it has to take the mode limiting load to make up transformator temperature increase requirement.
Utility model content
The purpose of this utility model is for the problems referred to above, it is provided that the Water spray heat abstractor of a kind of oil immersed self cooled transformer, reduces main transformer oil temperature for oil immersed self cooled transformer Load in Summer peak period, improves transformator tape splicing in summer load-bearing capacity.
This utility model is realized in, a kind of Water spray heat abstractor of oil immersed self cooled transformer, including water inlet pipe, gate valve and water pump, it is characterized in that water inlet pipe passes sequentially through water pump, gate valve connects spray header, spray header is contained in above transformator, installing several spray heads on spray header, spray head is directed at downwards radiating fin of transformer, sprays vaporific water smoke to radiating fin of transformer；Described water pump start and stop are controlled by pump motor controller, and pump motor controller connects intervalometer, make water pump set period unlatching at intervalometer.
It uses and installs shower nozzle above radiating fin of transformer additional, uses tap water to help fin to dispel the heat as temperature-reducing medium, the mode that current walk heat through fin strip, thus reduce temperature of oil in transformer；Water spray system uses automatic time switch controller to control, Load in Summer peak period, according to load period and climate condition, arranges timing means and controls the time that water pump opens and closes, thus avoid low-load period at night waste water resource.
The beneficial effects of the utility model are, this fin water spray system changes the type of cooling of transformator, by original self cooling change opening device into after the more preferable water of radiating effect help cold with self cooling combination mode, the particularly cooling effect when transformator ambient temperature is higher is especially apparent, and transformator will not be caused how to damage in insulation by vaporific water smoke.The transformator installing water-cooled spray additional at full capacity, can be greatly improved the service ability during the high temperature of transformator by tape splicing during high ambient temperature.Water pump sets period unlatching at intervalometer, it is to avoid the waste of water resource.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In the drawings, 1, water inlet pipe 2, spray header 3, spray head 4, gate valve 5, radiating fin of transformer 6, water pump 7, pump motor controller 8, intervalometer.
Detailed description of the invention
As shown in Figure 1, a kind of Water spray heat abstractor of oil immersed self cooled transformer, including water inlet pipe (1), gate valve (4) and water pump (6), it is characterized in that water inlet pipe (1) passes sequentially through water pump (6), gate valve (4) connects spray header (2), spray header (2) is contained in above transformator, spray header (2) is upper installs several spray heads (3), and spray head (3) is directed at downwards radiating fin of transformer (5), sprays vaporific water smoke to radiating fin of transformer (5)；Described water pump (6) start and stop are controlled by pump motor controller (7), and pump motor controller (7) connects intervalometer (8), make water pump (6) set period unlatching at intervalometer (8).
It uses radiating fin of transformer (5) top to install spray head (3) additional, uses tap water to help fin to dispel the heat as temperature-reducing medium, the mode that current take away heat through radiating fin of transformer (5), thus reduce temperature of oil in transformer；Water spray system uses intervalometer (8) hydrous water pump motor controller (7) to control water pump (6), in Load in Summer peak period, according to load period and climate condition, intervalometer (8) is set and controls the time that water pump (6) opens and closes, thus avoid low-load period at night waste water resource.
This water spray system changes the type of cooling of transformator, by original self cooling change opening device into after water help cold with self cooling combination mode, water helps cold cooling effect the most self cooling, the particularly cooling effect when transformator ambient temperature is higher is especially apparent, and transformator will not be caused how to damage in insulation by spray water.The transformator installing water-cooled spray additional at full capacity, can be greatly improved the service ability during the high temperature of transformator by tape splicing during high ambient temperature.
