Abstract
The utility model discloses a positioning and compressing device for a coil of a dry-type transformer, which uses standard components. The positioning and compressing device for the coil of the dry-type transformer comprises a channel steel (1). A cushion block and a fixing device for regulating a distance between the channel steel (1) and the cushion block are arranged between the channel steep (1) and the coil. The positioning and compressing device for the coil of the dry-type transformer is characterized in that the fixing device comprises a bolt (7) and a nut (8); a screw part of the bolt (7) is provided with the nut (8) and passes through the channel steel (1); and a head part of the bolt (7) is arranged in a groove of the cushion block. The utility model has the advantages of simple structure, convenient use, more effective increase of contact area of a pressing nail and the cushion block so as to make a pressed component more stable, low cost and reduction of production cost.
Description
Technical field:
The utility model relates to a kind of dry-type transformer, specifically a kind of dry-type transformer coil location, hold down gag.
Background technology:
In the structure of dry-type transformer, need between channel-section steel and coil, adopt usually and press nail, cushion block structure, be used for compressing the insulation distance between coil and the assurance high and low pressure coil.But it is screw rod that traditional pressure is followed closely an end, and the other end is fastening square head.During use, following closely also according to the different employed pressure of transformer device structure, length differs.And be nonstandard part, processing time consuming is taken a lot of work, and cost is also higher.Simultaneously, in use, owing to press nail less, need install one between nail and cushion block additional and press washer pressing, in order to increasing the contact area of pressing between nail and cushion block, in case answer pressure excessive and cushion block is crushed with the contact area of cushion block.But press washer also and non-standard component, equally also need special.
Summary of the invention:
The purpose of this utility model provides a kind of dry-type transformer coil location, hold down gag that uses standard component.
The utility model is to adopt following technical scheme to realize its goal of the invention, a kind of dry-type transformer coil location, hold down gag, it comprises channel-section steel, be provided with cushion block between channel-section steel and the coil and be used to adjust the fixture of distance between channel-section steel and the cushion block, fixture comprises bolt, nut, the threaded shank of bolt is equipped with nut and passes channel-section steel, and the head of bolt is placed in the groove of cushion block.
Be provided with pad between the head of bolt of the present utility model and the cushion block.
Because adopt technique scheme, the utility model has been realized goal of the invention preferably, it is simple in structure, and is easy to use, and the contact area between nail and cushion block is pressed in more effective increase, makes by casting die more firmly, and cheap, has reduced production cost.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the prior art constructions schematic diagram;
Fig. 4 is the left view of Fig. 3.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
By Fig. 3, Fig. 4 as can be known, usually between channel-section steel 1 and coil, adopt at present and press nail 9, cushion block structure, be used for compressing coil and guarantee insulation distance between high-tension coil 2, the low-voltage coil 3, cushion block comprises resin mat cushion block 5, rubber cushion blocks 3, but it is screw rod that traditional pressure is followed closely 9 one ends, and the other end is fastening square head.During use, differ according to the different employed pressure nail 9 of transformer device structure also length.And be nonstandard part, processing time consuming is taken a lot of work, and cost is also higher.Simultaneously, in use, owing to press nail 9 less, need install one between nail 9 and cushion block additional and press washer 10 pressing, in order to increasing the contact area of pressing between nail 9 and cushion block, in case answer pressure excessive and cushion block is crushed with the contact area of cushion block.But press washer 9 also and non-standard component, equally also need special.
As seen from Figure 1, Figure 2, a kind of dry-type transformer coil location, hold down gag, it comprises channel-section steel 1, be provided with cushion block between channel-section steel 1 and the coil and be used to adjust the fixture of distance between channel-section steel 1 and the cushion block, fixture comprises bolt 7, nut 8, the threaded shank of bolt 7 is equipped with nut 8 and passes channel-section steel 1, and the head of bolt 7 is placed in the groove of cushion block.
Be provided with pad 6 between the head of bolt 7 of the present utility model and the cushion block.
When the utility model uses, the threaded shank of bolt 7 is installed nut 8 and passes channel-section steel 1, the head of bolt 7 is placed in the groove of resin mat cushion block 5.Rotation nut 8 can compress coil and guarantee insulation distance between high-tension coil 2, the low-voltage coil 3 by rubber cushion blocks 3.Because the head of bolt 7 is bigger, also can regard a packing ring as, can also in the groove of resin mat cushion block 5, install a slice pad 6, the contact area of more effective increase and cushion block again additional, can better thrust be transmitted to cushion block around, make by casting die also more firm.
Claims (2)
1. dry-type transformer coil location, hold down gag, it comprises channel-section steel (1), be provided with cushion block between channel-section steel (1) and the coil and be used to adjust the fixture of distance between channel-section steel (1) and the cushion block, it is characterized in that described fixture comprises bolt (7), nut (8), the threaded shank of bolt (7) is equipped with nut (8) and passes channel-section steel (1), and the head of bolt (7) is placed in the groove of cushion block.
2. dry-type transformer coil according to claim 1 location, hold down gag is characterized in that being provided with pad (6) between the head of bolt (7) and the cushion block.
