Oil-immersed transformer
专利汇可以提供Oil-immersed transformer专利检索，专利查询，专利分析的服务。并且PURPOSE:To obtain an economical oil-immersed transformer with high reliability, which is installed and adjusted easily at the site and sound-insulating effect thereof is high, by introducing a lead wire at a line terminal and a lead wire at a neutral point in the same duct protrusively mounted to a transformer tank. CONSTITUTION:The line terminal of a high-tension winding is connected to an oil-gas bushing 12 through an oil duct 10 and a bushing fitting box 3, and directly coupled with a gas insulating switchgear 8 for a line. The neutral-point terminal of the high-tension winding is connected to an oil-gas bushing 18 through the duct 10, the box 3 and a bushing fitting box 16 for the neutral-point terminal, and directly coupled with a gas insulating switchgear 20 for a neutral- point circuit. The line terminal of a medium-tension winding is directly coupled similarly with gas insulating switchgears 9, 21 for the line and for the neutral- point circuit. Accordingly, the economical and high reliability oil-immersed transformer, which is installed and adjusted easily at the site and the sound-insulating effect thereof is high, is obtained.，下面是Oil-immersed transformer专利的具体信息内容。
