Embodiment Construction

[0020] The present invention will be described in further detail below by means of specific embodiments:

[0021] The reference numerals in the accompanying drawings of the description include: pad main body 1 , through hole 2 , positioning pipe 3 , through groove 4 , gasket 5 , and mounting frame 6 .

[0022] Such as figure 1 As shown, the dry-variable drawstring arc pad includes a semi-cylindrical pad main body 1 made of Bakelite and a circular through hole 2 opened in the axial direction of the pad main body 1 . A tubular positioning tube 3 is slidably connected in the through hole 2 . Four bosses are integrally formed on the outer side of the positioning tube 3 along the axial direction, and the inner wall of the through hole 2 is provided with four slideways matching the bosses; the bosses are slidably connected to the slideways. The positioning tube 3 is coaxial with the through hole 2 and can extend out of the through hole 2 . Positioning pipe 3 adopts rubber to make...

Abstract

The invention relates to an auxiliary element for a transformer, and particularly discloses a curved cushion block for a pull tape of a dry-type transformer. The curved cushion block comprises a cylindrical main cushion block body and a through hole, wherein the through hole is formed in the radial direction of the main cushion block body; a tubular positioning pipe is connected to the through hole in a sliding manner; the positioning pipe is coaxial with the through hole and can extend outside the through hole; a straight groove is formed in the plane of the main cushion block body; the through hole is formed in the center position of the straight groove; and a gasket is arranged in the straight groove. The curved cushion block is capable of rapidly locating and is uniform in stress; and the pull tape is firmly installed.

Description

technical field [0001] The invention relates to an auxiliary part of a transformer, in particular to an arc-shaped cushion block of a dry-variable pull belt. Background technique [0002] Dry-type transformer refers to the transformer whose iron core and winding are not immersed in insulating oil, and is widely used in local lighting, high-rise buildings, airports, wharf CNC machinery and equipment and other places. [0003] The pull strap of the dry-type transformer is used to fix the coil of the dry-type transformer on the mounting frame to achieve insulation and fastening. Because of the structural limitations of the mounting frame, usually the two ends of the drawstring are respectively fixed to the corners of the mounting frame by bolts. And between the bolt and the corner of the mounting frame, a rectangular spacer is used to increase the firmness of the installation. However, because the flat bottom surface of the rectangular spacer does not match the corner shape o...
