Abstract
The utility model discloses a coil compressing device of a dry-type transformer, which comprises a clamping piece, a set screw, a cushion block and a coil. One end of the set screw clings to the cushion block, the cushion block compresses the coil, the clamping piece is connected on an iron core of the transformer, a round hole is arranged on the clamping piece, the other end of the ser screw penetrates through the round hole, and a nut is connected on the set screw in a threaded manner. The nut which clings to the clamping piece is located between the clamping piece and the cushion block. When the nut is screwed, the set screw moves, and the force of the set screw for compressing the coil by the cushion block can be adjusted; so long as the round hole is arranged on the clamping piece and the end face of the nut stably clings to the clamping piece, the compressing of the coil can be realized depending on the threaded matching between the set screw and the nut. The clamping piece has the characteristics of simple processing, low cost, and convenient coil compressing process.
Description
Technical field
The utility model relates to a kind of coil compressing device for dry type transformer.
Background technology
In the existing coil compressing device for dry type transformer, folder is connected the end of iron core, offer screw on the folder, folder matches with holding screw by screw, and holding screw pushes against on cushion block, and cushion block compresses coil, moment when the thrust size basis of this coil screws holding screw is determined, owing to will offer screw on folder, therefore existing hold down gag processing is inconvenient, and the processing cost height.
Summary of the invention
The purpose of this utility model is to provide a kind of easy to process and coil compressing device for dry type transformer that cost is low.
In order to reach above purpose, the technical solution adopted in the utility model is: a kind of coil compressing device for dry type transformer, comprise folder, holding screw, cushion block, coil, one end of described holding screw pushes against on described cushion block, described cushion block compresses described coil, described folder is connected on the iron core of transformer, offer circular hole on the described folder, the other end of described holding screw passes described circular hole, nut has been threaded on the described holding screw, described nut and pushes against described folder between described folder and described cushion block.
Described cushion block comprises iron cushion block, epoxy cushion block, rubber blanket, and described holding screw pushes against on described iron cushion block, and described rubber blanket is pressed on the described coil, and described epoxy cushion block is clamped between described iron cushion block and the described rubber blanket.
Because the utility model has adopted above technical scheme, its advantage is: turn nut, holding screw is moved thereupon, holding screw is by the power scalable of cushion block line ball circle, as long as on folder, offer circular hole, rely on the threaded engagement mutually of holding screw and nut, and the end face of nut stably pushes against folder, the compressing of realization coil.This folder processing is simple, and cost is low, and the coil compaction process is convenient.
Description of drawings
Accompanying drawing 1 is a structure chart of the present utility model;
Accompanying drawing 2 is the enlarged drawing at A place in the accompanying drawing 1;
Accompanying drawing 3 is along the phantom of B-B direction in the accompanying drawing 2.
Embodiment
Further set forth concrete structure of the present utility model below in conjunction with accompanying drawing.
Shown in Fig. 1-3, a kind of coil compressing device for dry type transformer, comprise upper clamping piece 1, lower clamping piece 15, holding screw 2, cushion block 8, coil 7, the lower end of holding screw 2 pushes against on cushion block 8, and cushion block 8 compresses coil 7, cushion block 8 is laminated mutually by iron cushion block 5, epoxy cushion block 6, rubber blanket 9, the top is an iron cushion block 5, and the below is a rubber blanket 9, and the centre is an epoxy cushion block 6, the lower end of holding screw 2 pushes against on iron cushion block 5, and rubber blanket 9 is pressed on the coil 7.Upper clamping piece 1 is connected on the iron core 10 of transformer, coil 7 is sleeved on unshakable in one's determination 10, in order to reach tension iron core and the purpose that compresses coil, folder adopts channel-section steel, as Fig. 1, upper clamping piece 1 and lower clamping piece 15 comprise the channel-section steel waist 11 of tension unshakable in one's determination 10, be positioned at the shank 12 at waist two ends about in the of 11, shank and waist angle are 90 degree and have enough mechanical strengths, offer circular hole 13 on the following shank 12 of upper clamping piece 1, circular hole 13 is passed in the upper end of holding screw 2, the nut 14 that has been threaded on the holding screw 2, nut 14 and push against folder 1 between folder 1 and cushion block 8.In Fig. 1, the upper surface of nut 14 be against folder 1 following kink 12 below, nut 14 comprises two, a hex nut 3 and a hexagon thin nut 4, when the needs adjusting compresses the thrust of coil, turn nut 14, upwards turn nut 14, holding screw 2 moves down, further compress coil by pushing against cushion block, otherwise, turning nut 14 downwards, the power of pushing against of holding screw 2 diminishes.In the utility model,, rely on the threaded engagement mutually of holding screw 2 and nut 14, and the upper surface of nut 14 stably pushes against folder, the compressing of realization coil as long as on folder, offer circular hole.This folder processing is simple, and cost is low, and the coil compaction process is convenient.
