Abstract
The utility model relates to an oil tank of a high-potential isolation transformer. The oil tank is characterized by comprising a high-pressure epoxy cylinder, wherein the upper end of the high-pressure epoxy cylinder is provided with an upper cover plate while the lower end of the high-pressure epoxy cylinder is connected with a pedestal; a primary lead frame is arranged on the side face of the pedestal, and an insulation transformer is arranged on the pedestal; a high-voltage insulator is arranged inside the upper cover plate, with the installing end extended outside the upper cover; and a high-pressure leading-out protective sleeve is sleeved on the high-voltage insulator outside the upper cover plate. According to the oil tank of the high-potential isolation transformer, the high-pressure epoxy cylinder is served as the tank body, so that the oil tank is firm, sealed and hardly deformed; the tank body is made of high-voltage insulating material, so the distance for withstanding voltage is reduced, and the problem of arcing on the wall of the tank due to high voltage is not existent, therefore, the volume of the oil tank is greatly reduced, and moreover, the oil tank is conveniently processed, and the cost is saved as well. Due to compact structure and high integrity, the oil tank can be conveniently arranged and hoisted, and is firm.
Description
Technical field
The utility model relates to a kind of oil tank of transformer, especially a kind of high potential isolating transformer fuel tank that is used for direct current 250kV.
Background technology
Traditional oil tank of transformer generally adopts the iron fuel tank, owing to will consider the withstand voltage distance of transformer high-voltage position and tank wall, often can only adopt and do big way to casing and solve, and can not satisfy requirement of client, and processed complex, has the problem of difficult sealing; Often because weld seam rosin joint or expand with heat and contract with cold and cause weld cracking, thereby cause the phenomenon of fuel tank oil impregnate, cost is also higher.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the prior art, and a kind of high potential isolating transformer fuel tank is provided, and volume is little, good pressure-resistant performance.
The technical scheme that provides according to the utility model; Said high potential isolating transformer fuel tank; Characteristic is: comprise the high pressure epoxy cylinder, in the upper end of high pressure epoxy cylinder upper cover plate is set, the lower end of high pressure epoxy cylinder is connected with base; The base side is provided with elementary lead frame, and isolating transformer is installed on base; Inboard at said upper cover plate is provided with high-tension insulator, and the installation end of high-tension insulator stretches out the outside of upper cover plate, and sheathed high pressure is drawn protective jacket on the high-tension insulator in the upper cover plate outside.
On said elementary lead frame, leading-out terminal is set.
The elementary lead-in wire of said isolating transformer is connected on the leading-out terminal on the elementary lead frame, and the secondary lead of isolating transformer is connected on the high-tension insulator.
The utlity model has following advantage:
(1) the described fuel tank employing of the utility model high pressure epoxy cylinder, sealing, not yielding firm as casing; So because from reducing withstand voltage required distance as high voltage insulating materials; There is not high pressure and tank wall sparking problem; Thereby the fuel tank volume reduces greatly, and easy to process, practices thrift cost;
(2) the described oil tank base support of the utility model adopts iron plate making, and the suspension ring of the transformer of weldering system in the above mounting screw, earthing screw, elementary lead frame and lifting usefulness, compact conformation, integrated level is high, make install, lifting is convenient, and firmly;
(3) the described fuel tank upper cover plate of the utility model adopts the high pressure epoxy plate, can guarantee to reduce the size of insulator withstand voltage the time, and install high pressure additional and draw protective jacket, prevents that the high pressure exit from working the mischief to personnel or other equipment.
