The utility model discloses a converter transformer network side sleeve fitting and a converter station using the same. The converter transformer network side sleeve fitting comprises a converter transformer network side sleeve connecting part, an intermediate conductor and a tubular bus connecting part. The converter transformer network side sleeve connecting part and the tubular bus connecting part are electrically connected through an intermediate conductor; an intermediate conductor connecting fitting of the converter transformer network side sleeve connecting part is connected with the end part of the intermediate conductor; the intermediate conductor connecting fitting is electrically connected with the sleeve terminal connecting fitting through a flexible wire; the intermediate conductor connection fitting is slidably connected with the sleeve terminal connection fitting. A main holding clamp and a main pressing block of the tubular bus connecting part are connected with a tubular bus, an intermediate conductor connecting fitting is rotatably connected with the main holding clamp, and the tubular bus and the intermediate conductor connecting fitting are connected through a flexible wire. Meanwhile, the utility model discloses a converter station employing the fitting, and the sleeve fitting effectively reduces the acting force between equipment at two ends through a relative sliding and rotating connection structure. Equipment damage rate is greatly reduced.
