Description
Technical Field
The utility model belongs to the technical field of the transformer is manufactured, concretely relates to transformer stores up cabinet foot structure of oil tank, this structure can improve the efficiency of installing and removing of storing up the oil tank.
Background
The transformer union system generally comprises an oil conservator, a main/branch air duct, a lifting seat air duct system, a breathing system and an oil injection and drainage system. As shown in fig. 1, it is a schematic structural diagram of a conventional transformer piping system; fig. 2 is a schematic view showing the installation of a conventional transformer conservator. The main airway 2 is used for collecting the gas of each branch airway, and the branch airway has: a lifting seat connecting pipe 1 (connecting the main air pipe and a lifting seat height point through a flange), and a box cover connecting pipe 3 (connecting the main air pipe and the top of the box cover through a flange). The head end of the main air pipe 2 is connected with a gas relay and an oil conservator 4 through flanges.
The 220kV transformer has the requirements of considering the external insulation of a sleeve and the minimum occupied space of the overall structure of the transformer, and has a classic oil conservator position determining structure. The transformer header system of this configuration is mostly on top of the transformer tank cover. The existing oil conservator foot structure is high in foot, a main air guide pipe 2 and an oil conservator 4 are connected through an interface and then need to penetrate through the space in the middle of the foot, the bottom of the oil conservator foot is of a closed structure, and the foot is fixed on an oil tank cover through a transition support 6.
Fig. 3 is a schematic view showing a sectional structure of an existing transformer conservator. Because the main air pipe 2 needs to penetrate through the cabinet leg 5 of the oil conservator with the closed bottom surface, the transition bracket 6 and the cabinet leg 5 of the oil conservator are firstly installed, then the oil conservator 4 is installed, and finally the main air pipe 2 is installed. Because the main air pipe 2 penetrates through the gap of the oil conservator feet 5 with the closed bottom surface, the travelling crane can not directly hoist and mount the main air pipe 2 in place, and the upper part is shielded by the cabinet body of the oil conservator 4. When the main air pipe 2 passes through the cabinet feet 5 of the oil conservator with a closed bottom surface structure, the main air pipe 2 needs to be lifted manually for installation. Because the tank top space of the transformer oil tank is smaller, the installation difficulty is high, the labor and the time are wasted, and potential safety hazards of falling from the tank top of the oil tank exist in workers.
There may be some unexpected problems in the transformer production process, such as: sometimes, after the assembly is finished, the problem that the local discharge does not meet the standard requirement during the test needs to be solved and the problem needs to be solved and processed if necessary. At this moment, because oil conservator 4 is located the case lid top, if do not demolish oil conservator 4 and directly hang the cover (dismantle bell jar formula oil tank upper segment oil tank promptly) and have two problems: firstly, the hoisting height is not enough, and the traveling height of a factory building is not enough; secondly, the steel wire rope interferes with the oil conservator 4 when the oil conservator 4 is driven to be hoisted, so that subsequent cover hoisting work can be carried out only after the oil conservator 4 is dismounted. When the oil conservator 4 needs to be dismantled, the main air pipe 2 needs to be dismantled firstly because the oil conservator 4 is fixedly connected with the main air pipe 2; when the main air pipe 2 is removed, the main air pipe 2 is very inconvenient to remove because the main air pipe 2 interferes with the cabinet feet 5 of the oil conservator with a closed structure at the bottom surface. Subsequently, the operation of installing the main air pipe 2 needs to be repeated in the reverse direction. After the main air pipe 2 is removed, other components mounted on the oil tank cover are removed, such as: the lifting seat, the lifting seat connecting pipe 1, the bridge frame and the like can keep the installation state as long as the lifting seat, the lifting seat connecting pipe and the bridge frame do not interfere with the steel wire rope and do not interfere with the hanging cover.
