Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transformer oil drain joints, in particular to an oil drain joint capable of preventing blockage. Background Art
[0002] Oil draining is a common phenomenon in transformer operation. The main reasons are that the internal temperature of the transformer is too high, the transformer oil contains moisture or impurities, and the container is not airtight. These reasons cause the internal pressure of the transformer to be too high, and it is necessary to drain the oil to reduce the pressure and remove impurities. The transformer drains the oil through the oil drain joint.
[0003] The oil drain joint transports and discharges oil through the oil drain pipe. During the continuous oil discharge process, the oil will adhere to the inner wall of the oil drain pipe. When the oil drain pipe needs to be unblocked and prevented from being blocked, the oil drain pipe needs to be disassembled through the flange to ensure that the oil drain joint can discharge oil stably.
[0004] However, in actual use, the existing equipment prevents blockage by disassembling the oil drain pipe. When the oil drain joint is used for anti-blocking operation, the oil cannot be discharged in a dispersed manner during oil discharge. At the same time, the oil attached to the inner wall of the oil drain pipe cannot be scraped and removed. During oil drainage and filtration, the oil will be blocked in the filter aperture, thereby reducing the anti-blocking effect. In view of this, we propose an anti-blocking oil drain joint.
