Abstract
The utility model relates to a pressurizing device for the leak hunting of a water block of a transformer and belongs to the field of sealing technology. The pressurizing device comprises clamps and sealing flanges. Each clamp is in the shape of a semi-circular arc, ears are arranged on two sides of the each clamp, bolt holes are arranged on the ears, and fastening screw rods are symmetrically arranged on the outer surface of the each clamp; and an air inlet pipe and an air outlet pipe are separately arranged on the sealing flanges, and a manometer is connected to the air outlet pipe. According to the utility model, the clamps and the sealing flanges cooperated with the clamps are arranged on a U-type water block, and the air inlet pipe and the air outlet pipe are separately arranged on the sealing flanges, so the wielding quality of the U-shaped water block can be precisely judged via the manometer and an accident due to quality caused by the damage of the transformer because of an internal leak of the water block is prevented.
Description
Technical field
The utility model relates to a kind of transformer water-cooled head and suppresses leakage testing device, belongs to technical field of sealing technology.
Background technology
The low-voltage side outlet terminal majority of large-scale furnace transformer is U-shaped water cooling tube, and its design feature connects the transformer low voltage winding for the pipe outer wall, manages the cooling of inboard water flowing feedwater cold head.A U-shaped water cooling tube part is in fuel tank, and a part is placed in the fuel tank external chiasma.Because the inner space is little, two distances of intersecting between the water-cooled head of placing are very little, are easy to shine into the discharge sparking under the state of work, damage U-shaped water cooling tube.After U-shaped water cooling tube reparation after damaging finished, if there is not checking measure, be easy to cause because welding trachomas individually and leak to the damage of transformer integral body, in order to guarantee the quality of repaired item, I have made a cover and have suppressed leakage testing device, through the practice demonstration, this covering device can be checked the quality after the welding effectively.
Summary of the invention
The purpose of this utility model is to provide a kind of checking measure, high efficiency, safe and reliable transformer water-cooled head to suppress leakage testing device.
Technical solution:
The utility model comprises jig, seal flange, jig be shaped as semi-circular arc, the both sides of semi-circular arc are provided with the ears or side handles of a utensil, the ears or side handles of a utensil are provided with bolt hole, are symmetrically arranged with fastening screw at the outside surface of semi-circular arc; Seal flange is provided with draft tube and escape pipe, connects tensimeter on the escape pipe.
The inside surface of described semi-circular arc is provided with the sealing offset plate.
Of the present utility model owing to the seal flange that jig is installed and cooperates with jig at U-shaped water-cooled head, be provided with draft tube and escape pipe at seal flange, can accurately judge the welding quality of U-shaped water-cooled head by pressure, avoid owing to the quality accident that damage to transformer causes of leaking of water-cooled head inside.
