Abstract
The utility model discloses an automatic water cooling device of a transformer. The automatic water cooling device comprises a water pump, a spraying device and an automatic control device, wherein the automatic control device is connected with the transformer and the water pump respectively; and the water pump is connected with the spraying device. According to the automatic water cooling device disclosed by the utility model, the water pump can be automatically opened to supply water when the oil temperature of the transformer is too high; the spraying device is used for continuously spraying water to the transformer to reduce the temperature until the oil temperature of the transformer is recovered to be normal; and then the water pump is automatically closed so that the normal operation of the transformer can be reliably guaranteed. The automatic water cooling device of the transformer has the advantages of good temperature reduction effect, simple structure, stability and reliability, and convenience for machining and mounting.
Description
Technical field
The utility model belongs to transformer Cooling falling temperature technique field, is specifically related to a kind of transformer automatic water-cooling radiator cooler.
Background technology
Be subjected to the impact of global warming trend, China's summer temperature is more hot in recent years, and 35kV and the above high voltage substation main transformer temperature type of cooling adopt the oil immersion natural circulation cooling, when entering hot summer, the user power utilization amount is large, and transformer load increases, adding burning sun is exposed to the sun, transformer temperature is high thus, and transformer oil and its surrounding air temperature difference diminish, thereby causes the transformer oil cooling rate slack-off.Transformer temperature can't satisfy DL/T 572-2010＜＜the power transformer operating standard requirement of 4.1.3 " top-oil temperature of natural circulation cooling transformer generally should not often above 85 ℃ ", have to by drawing limited load to reduce the transformer body temperature, social production and life are caused seriously influence.
The utility model content
The utility model provides a kind of can effectively reduce transformer oil temperature, avoids drawing summer the transformer automatic water-cooling radiator cooler of limited load.
The technical scheme in the invention for solving the technical problem is: a kind of transformer automatic water-cooling radiator cooler, it is characterized in that: it comprises water pump, spray equipment and automatic control equipment, described automatic control equipment is connected with water pump with transformer respectively, and described water pump is connected with described spray equipment.
Described spray equipment is made of water delivery house steward, a plurality of delivery pipe branch and a plurality of sparge pipe, above sparge pipe is laid in around transformer body and the radiating tube, described sparge pipe is connected with described delivery pipe branch, and delivery pipe branch is connected with the water delivery house steward, and the delivery port of water delivery house steward and water pump is communicated with.
Described automatic control equipment arranges temperature detect switch (TDS) and the A.C. contactor that is connected signal transmssion line and is connected with temperature detect switch (TDS), and described A.C. contactor is connected with described water pump by wire.
The water inlet of described water pump is communicated to cyclic water tank.
Described spray equipment below arranges collecting-tank, and described collecting-tank is communicated with described cyclic water tank.
The utility model can be when temperature of oil in transformer be too high automatic open water water supplying pump, spray equipment continues spray cooling to transformer, until temperature of oil in transformer recovers normal, autoshutdown water pump then, thus guarantee reliably the normal operation of transformer.The utility model good cooling effect and simple in structure, reliable and stable, processing easy for installation.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1: a kind of transformer automatic water-cooling radiator cooler, comprise water pump 7, spray equipment and automatic control equipment, described automatic control equipment is connected with water pump with transformer respectively and is connected, and described water pump 7 is connected with described spray equipment.Described spray equipment is made of water delivery house steward 10, delivery pipe branch 2 and a plurality of sparge pipe 3, above sparge pipe 3 is laid in around transformer body 4 and the radiating tube 1, described sparge pipe 3 is connected with described delivery pipe branch 2, delivery pipe branch 2 is connected with water delivery house steward 10, and the delivery port of water delivery house steward 10 and water pump 7 is communicated with.Described automatic control equipment arranges temperature detect switch (TDS) 5 and A.C. contactor 6.The water inlet of described water pump 7 is communicated to cyclic water tank 8.Described spray equipment below arranges collecting-tank 9, and this collecting-tank 9 is communicated with described cyclic water tank 8.
During the utility model work, the temperature of temperature detect switch (TDS) 5 Real-Time Monitoring transformers, when temperature of oil in transformer reaches design temperature, connect described A.C. contactor 6 circuit by temperature detect switch (TDS) 5, and make A.C. contactor 6 closures, supply water thereby open water pump 7, this moment, spray equipment began transformer is continued spraying cooling.When temperature of oil in transformer is reduced to design temperature when following, connect described A.C. contactor 6 circuit by temperature detect switch (TDS) 5, and A.C. contactor is disconnected, thereby make water pump 7 water supply that shuts down, collecting-tank 9 is collected the water that sprays and is compiled automatic inflow cyclic water tank 8, water can be recycled, saved water resources.
