Abstract
The invention relates to a high-potential isolation transformer oil tank, which is characterized by comprising a high-pressure epoxy barrel, wherein the upper end of the high-pressure epoxy barrel is provided with an upper cover plate; the lower end of the high-pressure epoxy barrel is connected with a base; the side face of the base is provided with a primary lead frame; an isolation transformer is arranged on the base; the inner side of the upper cover plate is provided with a high-pressure insulator; the installation end of the high-pressure insulator extends out of the outer side of the upper cover plate; and a high-pressure lead-out protective sleeve is sleeved on the high-pressure insulator on the outer side of the upper cover plate. In the oil tank disclosed by the invention, the high-pressure epoxy barrel is taken as a tank body, so that the oil tank is firm and hermetic and is prevented from being deformed easily; the oil tank is made of a high-pressure insulating material, so that the distance required by pressurization can be reduced, the problem of fire striking between high pressure and a tank wall does not exist, and the size of the oil tank is reduced greatly; moreover, the oil tank is convenient to process, and cost is saved; and the oil tank has a compact structure and high integration degree, is convenient to install and hoist, and is firm.
Description
Technical field
The present invention 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 objective of the invention is to overcome the deficiency that exists in the prior art, a kind of high potential isolating transformer fuel tank is provided, volume is little, good pressure-resistant performance.
According to technical scheme provided by the invention, said high potential isolating transformer fuel tank, characteristic is: comprise the high pressure epoxy cylinder; Upper end at the high pressure epoxy cylinder is provided with upper cover plate; The lower end of high pressure epoxy cylinder is connected with base, and 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 present invention has the following advantages:
(1) fuel tank employing high pressure epoxy cylinder of the present invention, 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) oil tank base support of the present invention 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) fuel tank upper cover plate of the present invention 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.
