Abstract

The utility model discloses a device for improving an iron yoke insulation structure of an oil-immersed transformer and belongs to the technical field of iron yoke improvement. The device consists of iron yoke cushion blocks (1) and oil ways (2), wherein the iron yoke cushion blocks include a first iron yoke cushion block (1-1), a second iron yoke cushion block (1-2), a third iron yoke cushion block (1-3), a fourth iron yoke cushion block (1-4), a fifth iron yoke cushion block (1-5) and a sixth iron yoke cushion block (1-6), four oil ways are evenly formed on the first iron yoke cushion block, the second iron yoke cushion block, the third iron yoke cushion block and the fourth iron yoke cushion block respectively, and three oil ways are evenly formed on the fifth iron yoke cushion block and the sixth iron yoke cushion block respectively. The device for improving the iron yoke insulation structure of the oil-immersed transformer has the advantages that a production process is simplified through improvement, materials can be saved, the oil ways of coils are ensured to be unobstructed, the heat dissipation effect is improved, and the requirements for various electrical properties of the transformer are met.

Description

The modifying device of oil-filled transformer core insulation structure

Technical field

The utility model is a kind of oil-filled transformer core insulation device, particularly a kind of modifying device of oil-filled transformer core insulation structure, belongs to the iron yoke and improves technical field.

Background technology

At present, the core insulation structure of middle-size and small-size transformer generally adopts the paper circle of iron yoke cushion block (Manchurian ash), 2mm and sticks on the insulating board cushion block be combined into of the some above the paper circle of 2mm, the paper circle of 2mm is arranged on above the iron yoke cushion block, the insulating board cushion block is pasted on the paper circle of 2mm and is constituted oil duct, as shown in Figure 1, this structure is processed more complicated, and inconvenient operation had not only been wasted man-hour but also waste material.

Summary of the invention

Problem at above-mentioned prior art existence, the utility model provides a kind of modifying device of oil-filled transformer core insulation structure, by improving, not only can simplify production technology, can also save material, guarantee the unobstructed of coil oil circuit, improve radiating effect, satisfy the requirement of the every electric property of transformer.

To achieve these goals, the technical solution adopted in the utility model is: a kind of modifying device of oil-filled transformer core insulation structure, formed by iron yoke cushion block and oil duct, described iron yoke cushion block comprises iron yoke cushion block one, iron yoke cushion block two, iron yoke cushion block three, iron yoke cushion block four, iron yoke cushion block five and iron yoke cushion block six, iron yoke cushion block one, iron yoke cushion block two, iron yoke cushion block three and evenly offered four oil ducts above the iron yoke cushion block four respectively, iron yoke cushion block five and evenly offered three oil ducts above the iron yoke cushion block six respectively, described iron yoke cushion block one, iron yoke cushion block two, iron yoke cushion block three and iron yoke cushion block four are divided into two row and evenly are arranged on the coil, are respectively equipped with iron yoke cushion block five and iron yoke cushion block six in the left and right sides at its two ends.

The beneficial effects of the utility model are: by improving, not only can simplify production technology, can also save material, guarantee the unobstructed of coil oil circuit, improve radiating effect, satisfy the requirement of the every electric property of transformer.

Fig. 2 is the utility model structure chart.

Among the figure: 1, iron yoke cushion block, 2, oil duct, 1-1, iron yoke cushion block one, 1-2, iron yoke cushion block two, 1-3, iron yoke cushion block three, 1-4, iron yoke cushion block four, 1-5, iron yoke cushion block five, 1-6, iron yoke cushion block six.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As depicted in figs. 1 and 2, the modifying device of this oil-filled transformer core insulation structure, formed by iron yoke cushion block 1 and oil duct 2, described iron yoke cushion block 1 comprises iron yoke cushion block one 1-1, iron yoke cushion block two 1-2, iron yoke cushion block three 1-3, iron yoke cushion block four 1-4, iron yoke cushion block five 1-5 and iron yoke cushion block six 1-6, iron yoke cushion block one 1-1, iron yoke cushion block two 1-2, iron yoke cushion block three 1-3 and evenly offered four oil ducts 3 respectively above iron yoke cushion block four 1-4, iron yoke cushion block five 1-5 and evenly offered three oil ducts 3 respectively above iron yoke cushion block six 1-6, described iron yoke cushion block one 1-1, iron yoke cushion block two 1-2, iron yoke cushion block three 1-3 and iron yoke cushion block four 1-4 are divided into two row and evenly are arranged on the coil, are respectively equipped with iron yoke cushion block five 1-5 and iron yoke cushion block six 1-6 in the left and right sides at its two ends.

When using the modifying device of this oil-filled transformer core insulation structure, the thickness of iron yoke cushion block 1 is all increased, the paper circle of 2mm and the thickness sum of cardboard cushion block before the thickness that increases is equivalent to, and on iron yoke cushion block 1, evenly offered oil duct 2 respectively, can be so that oily flow unobstructed, in the production process, between transformer coil and iron yoke, place the rectangle cardboard that thickness is 1mm, mainly be with solving because of the coil that produces of paper circle of cancellation 2mm and the buffer action between the iron yoke, prevent that end winding from discharging to the iron yoke, after the improvement, not only simplify technology, saved material, also guaranteed oil duct smooth and easy of coil, radiating effect is better, satisfies the requirement of every electric property fully.
