Abstract
The utility model discloses a coil clamp device of a dry transformer, and particularly discloses a coil clamp device which has uniform stress and simple and convenient maintenance. The coil clamp device comprises a clamp, pressing pins and cushion blocks arranged at the periphery of a coil, and the utility model is characterized in that the lower end of the clamp is welded with a pressing plate with a positioning hole, the periphery of each pressing pin is screwed with a pressing sleeve, the cross section of each pressing sleeve presents a T shape, each pressing sleeve is penetrated in the positioning hole, the upper part of each pressing sleeve is provided with a standby nut, the surface of each cushion block is provided with a groove, a pressing cushion is arranged in each groove and the tail end of each pressing pin is pressed on each pressing cushion. The cushion block of the utility model has uniform stress and is not easy to loose, can attain better coil clamp effect, and can ensure the safe operation of the transformer; every pressing sleeve is movable and demountable, if the pressing sleeves are damaged, an impaired pressing sleeve or an impaired pressing pin is only replaced, so the maintenance is simple and convenient.
Description
(1) technical field under
The utility model relates to a kind of coil compressing device of dry-type transformer, particularly a kind of stressed evenly, the coil compressing device of easy maintenance.
(2) background technology
At present, use the device of pressing nail to compress coil, it presses the oncomelania mother to be welded on the board-like folder of transformer, presses nail to pass and presses the oncomelania mother to be pressed on the cushion block, presses nail to reach the purpose that compresses coil by tightening.Though this structure is widely used, but have some defectives: one is owing to press oncomelania mother's restriction, be difficult to a cushion block and dispose more than one pressure nail, be that cushion block compresses against a point, the discontinuity equalization of cushion block, along with the operational shock of transformer, cushion block gets loose easily, influences the transformer safe operation; It is two if press the oncomelania box thread because of corrosion or be subjected to damage, and whole device just can't play pressuring action, and presses the oncomelania mother to be welded on the folder, is difficult to change, in case damage often need be changed whole folder.
(3) summary of the invention
The utility model provides a kind of coil compressing device in order to overcome the deficiency of above technology, and it can not only satisfy the requirement of mechanical strength of transformer, and can make each cushion block stressed even, is difficult for getting loose, and is easy to change.
The purpose of this utility model is achieved in that
A kind of coil compressing device comprises that folder, pressure are followed closely and the cushion block of coil periphery, and its special character is: described folder lower end is welded with the pressing plate that has location hole; Press the nail periphery to be combined with gland, the gland cross section is "T"-shaped, is applied in the location hole, and gland top is female for being equipped with; The cushion block surface has groove, is provided with pressure pad in the groove, presses the end of nail to be pressed on the pressure pad.
Owing to adopted such scheme: the pressing plate that is welded on the folder lower end, can design the pressing plate size according to actual needs, the position of location hole, number, thereby cushion block can be arranged in only position, and can use a plurality of pressure nails to be pressed on the same cushion block, cushion block is stressed evenly, is difficult for getting loose, reach preferably that coil compresses effect, guarantee the safe operation of transformer; Each gland all is movable dismountable, if damage, only needs to change impaired gland or press nail, easy maintenance.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 scheme of installation of the present utility model;
The structural representation that Fig. 2 amplifies for the utility model;
Fig. 3 is the front view of folder;
Fig. 4 is the vertical view of folder.
Among the figure, 1 folder, 2 press nail, and 3 are equipped with mother, 4 glands, 5 pressing plates, 6 pressure pads, 7 cushion blocks.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises folder 1, presses the cushion block 7 of nail 2 and coil periphery, and folder 1 lower end is welded with the pressing plate 5 that has location hole; Press nail 2 peripheries to be combined with gland 4, gland 4 cross sections are "T"-shaped, are applied in the location hole, and gland 4 tops are for being equipped with female 3; Cushion block 7 surfaces have groove, are provided with pressure pad 6 in the groove, press the end of nail 2 to be pressed on the pressure pad 6.
Its use is as follows: at the pressing plate 5 of the lower end of folder 1 welding with some location holes, the gland 4 of T shape is passed location hole on the pressing plate 5 from lower to upper, follow closely 2 with the bolt consistent as pressing with gland 4 internal whorls, pressing nail 2 to load onto a conduct earlier is equipped with female 3 nuts that use, passes gland 4, be pressed on the pressure pad 6 that is placed in the cushion block 7 top potholes, tighten and press nail 2, up to reaching suitable thrust, thereby compress transformer coil.
Claims (3)
1. a coil compressing device comprises folder (1), presses the cushion block (7) of following closely (2) and coil periphery, and it is characterized in that: described folder (1) lower end is welded with the pressing plate (5) that has location hole; Press nail (2) periphery to be combined with gland (4), gland (4) cross section is "T"-shaped, is applied in the location hole, and gland (4) top is for being equipped with female (3); Cushion block (7) surface has groove, is provided with pressure pad (6) in the groove, presses the end of nail (2) to be pressed on the pressure pad (6).
2. coil compressing device according to claim 1 is characterized in that: described pressure nail (2) is for a plurality of.
