Description

Suit frock of doing transformer coil

Technical Field

The utility model relates to a transformer manufacturing technology field, concretely relates to suit frock of doing transformer coil.

Background

At present, epoxy resin dry-type transformers are widely applied due to excellent fireproof characteristics, and how to improve the assembly speed and the productivity efficiency of products is a subject of concern of transformer manufacturers. The technical and economic indexes of the dry-type transformer determine that the structure of the dry-type transformer is as follows from inside to outside in sequence: the core leg 01 → the low voltage coil 03 → the high voltage coil 02, and the low voltage coil 03 has a convex line 01a as shown in fig. 1. Therefore, in the dry-type transformer coil, after the yoke is opened, the outer high-voltage coil and the inner low-voltage coil are sleeved together by using a tool such as a sling. The high-voltage coil is easier to be sleeved into the iron core column, but when the high-voltage coil is sleeved into the low-voltage coil again, the distance between the high-voltage coil and the low-voltage coil is small (about 10mm between the iron core column and the low-voltage coil and about 30mm between the low-voltage coil and the high-voltage coil), so that the high-voltage coil is difficult to avoid, wastes time and labor and is not safe.

Detailed Description

The technical solution of the present invention will be clearly and completely described with reference to the accompanying drawings. In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Please refer to fig. 2-3.

The utility model discloses a do suit frock of transformer coil, it is used for pre-assembly low tension coil 03 and high tension coil 02, and it includes two vertical screw rods 7. The two screws 7 penetrate through an annular gap between the low-voltage coil 03 and the high-voltage coil 02 which are sleeved inside and outside downwards.

The two screws 7 are opposed at both ends in the radial direction. An upper nut 3, an upper flat pad 4, an upper pressing block 5, a rubber pad 6, a lower pressing block 8, a lower flat pad 9 and a lower nut 10 are sequentially sleeved on each screw 7 from top to bottom.

The lower nut 10 locks the lower flat gasket 9 and the lower pressing block 8 upwards against the lower end faces of the low-voltage coil 03 and the high-voltage coil 02. The upper nut 3 locks the upper flat gasket 4, the upper pressing block 5 and the rubber gasket 6 downwards against the upper end surfaces of the low-voltage coil 03 and the high-voltage coil 02. The upper end of each screw 7 is also fixed with a hanging ring 1.

After the low-voltage coil and the high-voltage coil are combined and fixed through the sleeving tool, the low-voltage coil and high-voltage coil combined body can be lifted and sleeved on the iron core column through the lifting appliance 04.
