Background technology
At present, be to follow closely to compress high-voltage coil and low-voltage coil by fixing iron cushion block or rubber cushion blocks or epoxy resin cushion block and metal crimp between poured with epoxy resin transformer coil and the iron core, its structure can be with reference to shown in Figure 1: comprise folder 1, transformer coil 3 on the iron core that is connected transformer, epoxy resin cushion block 5 is connected on the folder 1 by metal crimp nail 6, and the top of transformer coil 3 is pressed on the epoxy resin cushion block 5.
Be the Chinese patent " coil compressing device " of CN2773873Y referring now to notification number, comprise folder, press nail with cushion block, be welded with the pressing plate of band location hole under the folder, press the outer gland that is rotary with of nail, be applied in the location hole, gland top is female for being equipped with, and cushion block just has groove on the face, be provided with pressure pad in the groove, press the end of nail to be pressed on the pressure pad.
Be the Chinese patent " a kind of coil compressing device for dry type transformer " of CN101930834A with reference to notification number, comprise folder, holding screw, cushion block, coil, one end of holding screw pushes against on cushion block, cushion block compresses coil, and folder is connected on the iron core of transformer, offers circular hole at folder, the other end of holding screw passes circular hole, the nut that has been threaded on the holding screw, nut and push against folder between folder and cushion block.
Generally speaking all there is following shortcoming in the patent of above-mentioned analog structure:
1, since the radial size of the transformer coil of different size have nothing in common with each other, desired cushion block overall dimensions are also inequality, need supplier's special facture, and used casting mold when needing to make, like this, the standardization level of part is very low, processing charges is very high;
2, in the coil assembling process, owing to the cushion block size is fixed, highly bad accent, assembling accumulated error adjustment amount is less;
3, existing epoxy resin cushion block and metal crimp nail compressing structure briquetting is pressed a high-voltage coil and low-voltage coil simultaneously, is unfavorable for prolonging the creepage distance of high-voltage coil and low-voltage coil.
Summary of the invention
The object of the invention provides a kind of basic hold down gag in position of dry-type transformer coil.
For achieving the above object, the technical solution used in the present invention is:
A kind of basic hold down gag in position of dry-type transformer coil, comprise folder on the iron core that is connected transformer, be connected the basic assembly in position on the described folder, transformer coil pushes against on the basic assembly in described position, the basic assembly in described position comprises the basic cap in position, position pedestal, at least one basic regulating block, at least one position pilum that is connected with the basic cap in described position and the buffer insulation pad that is arranged on pilum bottom, described position, described position pedestal has a cavity, and described position pilum is pressed on the basic regulating block in described position in the cavity of described position pedestal.
Preferably, the described basic regulating block in position and buffer insulation pad are elastomeric element.
Preferably, described position pilum is provided with many, the mutually upper and lower clamping successively of many described position pilums.
Preferably, the basic cap in described position and described pedestal are by being threaded.
Preferably, the basic cap in described position is connected with described folder by the locking device of self.
Preferably, the material of the basic cap in described position, position pedestal and position pilum is the synthetic material of short glass fiber and polyester amine 66.
Because technique scheme is used, the present invention compared with prior art has following advantage and effect:
The present invention is by a kind of height-adjustable combination die blocking hold down gag, and the standardization that position each part of basic assembly is realized reduces the differentiation of product, and is applicable to the transformer of various models; The basic assembly in position can compress the high and low pressure coil respectively, and prolongs creep distance between them to greatest extent, saves because original needed die cost of epoxy resin cushion block greatly.
Description of drawings
Accompanying drawing 1 is the structural representation of coil compressing device in the prior art;
Accompanying drawing 2 is structural representation of the present invention;
Accompanying drawing 3 is the fractionation schematic diagram of meta base assembly of the present invention.
Wherein: 1, folder; 2, the basic assembly in position; 20, the basic cap in position; 21, position pedestal; 22, the basic regulating block in position; 23, position pilum; 24, buffer insulation pad 3, transformer coil; 30, interior loop; 31, exterior loop; 4, iron core; 5, epoxy resin cushion block; 6, metal crimp nail.
Embodiment
Below in conjunction with drawings and Examples the present invention is further described:
The basic hold down gag in position of a kind of dry-type transformer coil as shown in Figure 2 comprises folder 1 on the iron core 4 that is connected transformer, is connected the basic assembly 2 in position on the folder 1, and transformer coil 3 pushes against on the basic assembly 2 in place.
As shown in Figure 3, specifically: the basic assembly 2 in position comprises the basic cap 20 in position, position pedestal 21, at least one basic regulating block 22, at least one position pilum 23 and the buffer insulation pad 24 that pilum in place 23 bottoms are set.The basic cap 20 in position is connected on the folder 1, can be connected by the locking device of self on the folder 1; Pedestal 21 sheathed basic caps in place 20 inside, position, both are connected by screw thread, and position pedestal 21 has a cavity; The basic regulating block 22 in position can be selected elastomeric element, and as rubber or silicon rubber, its quantity and size can be according to the actual conditions adjustment; Position pilum 23 is provided with one or more, can specifically select the quantity of a pilum 23 by the height of transformer coil 3, when selecting many position pilums 23, and many position pilum 23 mutually upper and lower clampings successively; Buffer insulation pad 24 also is chosen as elastomeric element, as rubber or silicon rubber, and is close to a pilum 23 lower ends and directly contacts with transformer coil and play cushioning effect.The material of the basic cap 20 in position, position pedestal 21 and position pilum 23 is the synthetic material of short glass fiber and polyester amine 66.Like this, when using, many position pilums 23 compress position base regulating block 22 in the cavity of pedestal 21 in place.
