Description
technical field:
The utility model relates to a kind of transformer protector, particularly relates to a kind of transformer cooler dustproof filtering device.
background technology:
1000kV transformer is one of three large nucleus equipments of extra-high-voltage alternating current transformer station, and can how its operation conditions is related to Test and pilot project safe and stable operation.Station, 1000kV extra-high voltage Nanyang operation maintenance personnel find 1000kV transformer body become oil temperature, around temperature when environment temperature and load substantially constant, oil temperature, to rise nearly 5 DEG C around temperature.Main body becomes in running order radiator inlet side and is blocked by similar " cotton-wadded quilt " foul to go to site inspection equipment state to find.Obviously can feel before standing in radiator fan that wind-force decreases many, and be in fan radiating device inlet side that is auxiliary or stand-by state and there is no similar " cotton-wadded quilt " foul.As everyone knows, if after transformer insulated operating temperature exceedes permissible value, often raise 8 DEG C of its useful life (life-span) and just reduce half, i.e. transformer life 8 DEG C of rules.
The inlet and outlet of transformer is the cross-ventilated passage of Transformer, once blocking or laying dust, the heating condition of transformer does not become and radiating condition has been deteriorated, and can not air heat radiation towards periphery cause Transformer temperature to raise in time.Divide station, Nanyang according to Henan Electric Power System gradation for surface pollution and be located in the filthy district of " D " level.Annual spring, poplar wadding catkin just just like all over the sky snow gently wave and wave.In running order radiator fan rotates and forms eddy current and produce absorption affinity and causes poplar catkin of wadding a quilt with cotton to be adsorbed on surface, and to add at a time when this wheat harvest season, wheat gray scale is comparatively large, and poplar wadding catkin very easily adsorption of dust to cause radiator to block serious.
utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provides that a kind of reasonable in design, structure is simple, transformer cooler dustproof filtering device that easy accessibility and being convenient to cleans.
The technical solution of the utility model:
A kind of transformer cooler dustproof filtering device, containing framework and filter screen, the two ends up and down of described framework are respectively arranged with fixed block, at least two filter screens are provided with between described fixed block, beam is provided with between neighbouring described filter screen, described in each, the both sides of filter screen are respectively arranged with handle, and described handle is fixing on said frame.
Described fixed block is four, is L shape, is distributed in topmost and the external corners place of described filter screen bottom.Described filter screen is made up of metal edge frame and filter cloth, is provided with gripper shoe in the middle of described metal edge frame.Described metal edge frame, filter cloth and gripper shoe are made by aluminium alloy or stainless steel.
The both sides of filter screen described in each are respectively arranged with two described handles, and described handle is fixed on said frame by rotating shaft and spring; Described framework is fixed on the cooler of transformer.
The beneficial effects of the utility model:
1, the utility model is arranged on radiator inlet side, can effectively prevent floating thing from floating on cooler, ensure the duty of cooler, also possessing in addition does not have a power failure carries out cleaning, convenient operation, does not affect various functions that radiator normally works and should possess outdoor large oil-filled equipment annex service condition.
2, the utility model adopts multiple filter screen to arrange to form, be provided with beam, both reduced noise, reduce again the damage of filter screen, extender service life between adjacent screen.
3, each filter screen both sides of the utility model at least arrange two handles, can limit the right position of filter screen, can facilitate again the dismounting of filter screen, convenient and swift.
4, the utility model two ends arrange fixed block respectively, and its fixed block is L shape, effectively ensure that the position of filter screen, increase dustproof filter effect.
5, the utility model filter screen is made up of metal edge frame and filter cloth, is convenient to fix, and is provided with gripper shoe in addition in the middle of metal edge frame, improves the load effect of filter cloth.
6, the utility model is reasonable in design, structure is simple, easy accessibility and be convenient to cleaning, applied widely, be easy to promote, economic benefit is good.
accompanying drawing illustrates:
Fig. 1 is the structural representation of transformer cooler dustproof filtering device.
detailed description of the invention:
Embodiment: see in Fig. 1, figure, 1-fixed block, 2-handle, 3-framework, 4-beam, 5-metal edge frame, 6-filter cloth, 7-gripper shoe.
Transformer cooler dustproof filtering device contains framework 3 and filter screen, wherein: the two ends up and down of framework 3 are respectively arranged with fixed block 1, at least two filter screens are provided with between fixed block 1, beam 4 is provided with between neighbouring filter screen, the both sides of each filter screen are respectively arranged with handle 2, and handle 2 is fixing on the frame 3.
Fixed block 1 is four, is L shape, is distributed in topmost and the external corners place of filter screen bottom.Filter screen is made up of metal edge frame 5 and filter cloth 6, is provided with gripper shoe 7 in the middle of metal edge frame 5.Metal edge frame 5, filter cloth 6 and gripper shoe 7 are made by aluminium alloy or stainless steel.
The both sides of filter screen are respectively arranged with two handles 2, can prevent filter screen tilted upward, and handle 2 is fixed on the frame 3 by rotating shaft and spring; Framework 3 is fixed on the cooler of transformer.
Filter screen effectively prevents the floating thing in air from floating on cooler, to keep the cooling effect of cooler, when filter screen having attachment, can not have a power failure, directly wash filter screen, reduces power off time.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
