The present embodiment is when solar light irradiation intensity increases, a thermal expansion shrinkage liquid in a plunger shaft of a thermal expansion telescoping mechanism is owing to being subject to the effect of solar light irradiation, a thermal expansion shrinkage heated liquid expands, promote a piston to move up, piston driving expansion link also moves up, an expansion link pulls one end of a stay cord to move, the other end of a stay cord just pulls up puggaree, puggaree just blocks direct irradiation of sunlight on oil tank of transformer, oil tank of transformer is subject to the intensity of solar light irradiation just to reducing, thus oil tank of transformer variations in temperature affects also lower by solar light irradiation.By puggaree, blocking of sunlight is carried out to oil tank of transformer, effectively reduce external irradiation thermal source to the impact of oil tank of transformer temperature.This programme, when strong solar light irradiation, is automatically opened puggaree and is sheltered from strong sunlight, reduces the photo-irradiation intensity of direct irradiation of sunlight oil tank of transformer, makes the rising impact of sunlight on oil tank of transformer temperature less.When solar light irradiation intensity reduces, an expansion link of a thermal expansion telescoping mechanism shrinks, and automatic curled shrinks puggaree and furled puggaree.By to the three-way pipe be connected on the venthole of conservator and the free-extension bellows be connected on two other arm of three-way pipe and pressure valve, ensure freely changing of cold oil volume in conservator by free-extension bellows, ensure the excessive expansion of cold oil in conservator and excessive shrinkage by pressure valve.Guard box can protect free-extension bellows as far as possible not with sunlight or the contacting rain water in the external world, reduce the ageing progress of free-extension bellows, extend the useful life of this programme, reduce costs.The inlet opening of water pumper is connected with a case hole of metal water tank by conduit, and the apopore of water pumper is connected with a stomidium of metal heat-conducting block by conduit, and another stomidium of metal heat-conducting block is connected with another case hole of metal water tank.After connecting like this, just metal heat-conducting block, metal water tank and water pumper are connected in series rear acquisition closed cavity by conduit, and at the in-built full water of described closed cavity.When oil tank of transformer temperature raises, the cold oil in oil tank of transformer is understood some cold oil due to volumetric expansion and to be entered in conservator and to enter in the inner chamber of free-extension bellows.During temperature height, free-extension bellows is flexible longer, and the current signal that current sensor detects is larger; When temperature is low, free-extension bellows is flexible shorter, and the current signal that current sensor detects is less.The draw water speed of current signal to water pumper that controller transmits according to current sensor sends corresponding instruction, allows the temperature of oil tank of transformer remain in preset range, to allow this oil tank of transformer be operated in optimum state.Use simple, labour intensity is low.When free-extension bellows up extends, support bar also up moves, and now the slide of slide rheostat also up moves under the effect of support bar.Slide more up moves, and the current signal that current sensor detects is stronger.When controller receive current sensor send a certain size current signal time, controller is to water pumper work order, and water pumper starts to draw water and to cool oil tank of transformer.Towards a direction flowing in the closed cavity that water pumper obtains by water after metal heat-conducting block, metal water tank, water pumper and tubes connection.So just the water that temperature in metal water tank is relatively low is extracted in the cavity of metal heat-conducting block; under the effect of heat trnasfer; soon the temperature of oil tank of transformer is lowered; ensure that oil tank of transformer is operated in predetermined operating temperature range; improve the operating efficiency of oil tank of transformer, protection oil tank of transformer is not burned.When oil tank of transformer temperature continues to raise, free-extension bellows can continue up to extend, and support bar can continue up to move, and slide also can continue up to move.Slide continue up mobile after, it is larger that controller receives the current signal that current sensor sends, and controller sends the work order strengthening and draw water to water pumper, water pumper increasing is drawn water.Here, the speed of drawing water of water pumper is large and become large with the change of electric current on slide rheostat.The speed of drawing water of water pumper increases with the increase of electric current on slide rheostat, and the amount that cooling water enters into metal heat-conducting block cavity is more, and cooling effect is better.When after oil tank of transformer cooling, free-extension bellows can shrink, and support bar can move down, and slide can move down.When slide continues to move down, controller sends the instruction reducing to draw water to water pumper, and water pumper reduces takes out water-cooled speed.Here, the speed of drawing water of water pumper diminishes with electric current on slide rheostat and diminishes, and the amount that cooling water enters into metal heat-conducting block cavity is fewer, can keep good cooling effect.Intelligent, automaticity is high.This programme can according to the change of oil tank of transformer temperature, automatically can start and cooling down is carried out to oil tank of transformer, and water pumper can accelerate to draw water cooling rate along with the rising of oil tank of transformer spin manifold temperature, can reduce along with the reduction of oil tank of transformer spin manifold temperature cooling rate of drawing water, this programme can be reduced to the temperature of oil tank of transformer in the operating temperature range of oil tank of transformer rapidly.The present embodiment strictly can also can seal cold oil while reduction cold oil temperature, and reliability is high, good stability
