Abstract
The utility model relates to a fire prevention device for an oil-immersed transformer, in particular to an oil pit cover for an oil-immersed electrical appliance in a transformer station. The utility model is characterized in that a cement cover is provided with an oil leaking hole and the periphery of the cement cover is provided with an angle iron frame. The oil pit cover is the improvement of the prior oil pit; on the premise of ensuring the safe use of an oil pit, cobbles arranged inside the oil pit are not needed; and an originally open oil pit is closed by a cover with a hole, so problems caused by that dust and sand enter the oil pit are solved and the oil pit can be conveniently cleaned. When an oil pit is large, a pillar is arranged inside the oil pit, and the cover with a hole is put on the pillar and is supported by the pillar.
Description
Technical field
The utility model relates to oil immersed apparatus oil hole cover plate in the firebreak device of oil-filled transformer, particularly transformer station.
Background technology
At present, oil-filled transformer is according to designing requirement, one of fire safety facility that is adopted is that an oil hole is set, in the oil hole, fill cobble, be provided with oil-drain pipe and draining valve in the You Keng bottom, when oil-filled transformer generation leakage of oil, transformer inside or outside line local fault, make oil storage splash to ground and flow in the oily stone layer of cheating, thereby play certain fire prevention mitigation effect from the nozzle opening ejection.By using for a long time in the west area, there is following shortcoming in this design: because the west area dust storm is bigger, oil-drain pipe is stopped up in the sand and dust long-term accumulation easily, causes oil extraction speed slow, needs the sand and dust in the periodic cleaning oil hole, and workload is very big.
Summary of the invention
The purpose of this utility model is to overcome the defective that prior art exists, and provides a kind of and can reduce effectively and prevent that sand and dust from entering oil immersed apparatus oil hole cover plate in the oily transformer station that cheats.
For achieving the above object, the technical solution of the utility model is: oil immersed apparatus oil hole cover plate in a kind of transformer station, it is characterized in that having on the cement cover board oil leaking hole, and the periphery of cover plate is equipped with angle iron frame.
Above-mentioned cement cover board is made by armored concrete.
The utility model is the improvement to existing oil hole, under the prerequisite that guarantees the safe handling of oil hole, omitted the cobble that is placed in the oil hole, simultaneously former unlimited oil hole is sealed by cover plate with holes, solve sand and dust and entered the problem that the oil hole is brought, owing to do not place cobble in the oil hole, the cleaning to the oil hole just is very easy to so simultaneously.When the oil hole is big, in the oil hole, be provided with column, cover plate with holes is placed on the column, supports by column.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is overlooked for accompanying drawing 1.
Embodiment
As shown in Figure 1, 2, have the hole 3 that is used for leakage of oil on the cover plate 2, in order to make the spacing between cover plate and the cover plate less, be convenient to the making of cover plate and the overall appearance in oil hole simultaneously, at the periphery of cover plate angle iron frame 1 is housed, cover plate can adopt armored concrete system.The shape of cover plate can be made according to the shape in oil hole.Become when oil-filled transformer has an accident, the oil in the transformer just can enter by the hole on the cover plate in the oil hole.When oil is cheated when excessive, can in the oil hole, a plurality of columns be set as required, determine the size of cover plate according to the spacing distance of column.
Claims (2)
1, oil immersed apparatus oil hole cover plate in a kind of transformer station is characterized in that having oil leaking hole (3) on the cement cover board (2), and the periphery of cover plate (2) is equipped with angle iron frame (1).
2, oil immersed apparatus oil hole cover plate in the transformer station according to claim 1 is characterized in that above-mentioned cement cover board (2) made by armored concrete.
