[0001] The utility model relates to the technical field of main transformer oil pits, in particular to a water sealing device on a main transformer oil pit. Background Art
[0002] In order to prevent the burning and explosion of wastewater from accidents in the main transformer from spreading along the oil drainage network and causing fires and other accidents, most substations now use a separate water seal well at the outlet of the main transformer oil pit to meet fire protection requirements. The disadvantage of this approach is that each main transformer needs to have a separate water seal well, which occupies a large area and is not conducive to the layout of other pipelines; the water seal well is arranged in front of the main transformer, and considering the load-bearing problem, it is not convenient for the main transformer to be installed in place; during the construction process, it is necessary to excavate the foundation pit separately and lay bricks on site to make the water seal well, which takes a long time and consumes manpower; and the water seal well needs regular inspection and maintenance, and the water seal well has a lot of data, and the cost of later inspection and maintenance is high. Therefore, we proposed a water seal device on the main transformer oil pit to solve the above-mentioned problems. Utility Model Content
