An oil storage and transportation tank for adding oil to a power transformer

Abstract

The invention discloses an oil tank for storing and transporting power transformer additive oil. The oil tank is used for storing the power transformer additive oil, and comprises an oil tank body, an oil injection and drainage device, an oil level display device, a moisture absorber device, a vacuum interface device, a manhole device and an oil sample pumping device, wherein the exterior of the oil tank body has a cuboid structure on the whole, the side wall of the oil tank body has a corrugated structure, the bottom surface of the interior of the oil tank body has a gradient, the top of the oil tank body is provided with an oil baffle, and the bottom of the oil tank body is provided with support legs; the oil injection and drainage device comprises a valve; the valve is connected with a lowest pipe joint arranged between the bottom of the oil tank body and the bottoms of the support legs. The oil tank has the advantages of being attractive in appearance and low in manufacturing cost, not occupying the transportation area and being free from residual oil accumulation, and has the functions of dehumidification, vacuum oil injection, oil level display, oil sampling, easy clean, prevention of burglary and the like. After the technical scheme is implemented, the three manufactured oil tanks including 3.5T, 6T and 7T have better effects in the aspect of storing and transporting the power transformer additive oil.

Description

technical field [0001] The invention is a device for adding oil to a power transformer for storage and transportation, in particular to an oil storage and transportation tank for adding oil to a power transformer. Background technique [0002] In order to reduce the size and weight of transportation, the main parts of large-scale transformers must be disassembled for each oil discharge before shipment, and the transformer oil in the stock of the disassembled parts needs to be refilled after the parts are assembled at the installation site. It is estimated that the average amount of oil added to each transformer is about 5 tons. If a 200 kg storage oil barrel is used, dozens of them will be used at a time, which seems to be scattered, and there are uncontrollable liquid levels and residual oil when filling and discharging oil. Problems such as residual oil; if an outsourced oval oil tank is used, because of its longer length, it appears to occupy more space, and the service l...

Problems solved by technology

It is estimated that the average amount of oil added to each transformer is about 5 tons. If a 200 kg storage oil barrel is used, dozens of them will be used at a time, which seems to be scattered, and there are uncontrollable liquid levels and residual oil when filling and discharging oil. Residual oil and other problems; if you use an outsourced oval oil tank, because the length is longer, it seems to occupy more space, and the service life of the magnetic flap type oil level gauge is also shorter
