Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail, but does not constitute any limitation of the invention.
As shown in Figure 1, the C level three dimensional wound core dry-type transformer that a kind of suspension type is installed comprises upper clamping piece 1, and lower clamping piece 2 is arranged on iron core 5 between upper clamping piece 1 and the lower clamping piece 2 and the coil 7 on the iron core; Upper clamping piece 1 and lower clamping piece 2 are provided with silicagel pad 6 with 5 contact-making surface places unshakable in one's determination.
Described coil 7 is provided with briquetting 8 and presses nail 9 on iron core between described coil 7 upper surfaces and the upper clamping piece 1, be provided with briquetting 8 between coil 7 lower surfaces and the lower clamping piece 2.
As shown in Figure 4, described upper clamping piece 1 and lower clamping piece 2 are welded into by steel earlier and are roughly leg-of-mutton framework, afterwards installing rack 3 and pressing plate 4 are welded on this triangular framing.Upper clamping piece 1 is connected by four clamping screws 10 with lower clamping piece 2, by tightening up the nut that is located on the clamping screw 10, can regulate the distance between the upper and lower folder 1,2, i.e. the height of transformer.After tightening up, pressing plate 4 can guarantee that unshakable in one's determination 5 do not take place to go here and there up and down, and can protect iron core can not be subjected to external impact.Be provided with stay between the coil 7 and unshakable in one's determination 5, make coil 7 and unshakable in one's determination 5 one-tenths as a whole, thereby relative displacement can not take place between coil 7 and the iron core 5 when guaranteeing to take place to shake.
The upper surface of the briquetting 8 that is placed on the lower clamping piece 2 is close in the lower surface of coil 7, presses nail 9 to make briquetting 8 compress coil 7 by tightening up again, thereby makes iron core 5, coil 7 and the upper and lower folder 1,2 of whole transformer constitute an integral body.Whole transformer is installed on the erecting bed by the installing rack 3 that is provided with on upper clamping piece 1 and the lower clamping piece 2.
Described briquetting 8 upper surfaces have groove, press the nail lower surface to inlay in the groove, press between nail and the briquetting in the time of can guaranteeing vibrations take place and relative displacement can not take place, thereby can better compress coil 7.
As shown in Figure 2, high-tension coil has three binding posts 31,32,33, as shown in Figure 3, low-voltage coil four binding posts 41,42,43,44 are arranged, high-tension coil has four binding posts 41,42,43,44 that have of three binding posts 31,32,33 and low-voltage coil to arrange on the lead frame 11 of the both sides that are located at transformer respectively.The modes of emplacement of this kind binding post has effectively been saved the transformer locational space at both ends up and down, and then has dwindled the volume of transformer, and user's wiring when making things convenient for the transformer suspension type to install.
As shown in Figure 5, described coil 7 is made up of high-tension coil 21, low-voltage coil 22 and electrostatic shielding 23, high-tension coil 21 is arranged on the middle part, the upper and lower of high-tension coil 21 is arranged on low-voltage coil 22, the coiling on same iron core of high-tension coil and low-voltage coil, electrostatic shielding 23 are arranged between high-tension coil 21 and the low-voltage coil 22.Stay 25 is along axial setting unshakable in one's determination, and dovetail cushion block 24 is disposed radially; One end of dovetail cushion block 24 and stay 25 are fitted.
As shown in Figure 3, be provided with the little air flue that dovetail cushion block 24 is propped up between high-tension coil 21 each line cake and between low-voltage coil 22 each line cake, be provided with big airways between high-tension coil and the low-voltage coil, be provided with dovetail cushion block 24 between electrostatic shielding 23 and high-tension coil 21 and the low coil 22, constitute between electrostatic shielding 23 and the high-tension coil 21 and constitute second largest air flue 72 between first air flue 71, electrostatic shielding 23 and the low-voltage coil 22; The air flue direction is consistent with the erecting bed wind direction, can guarantee transformer good heat radiation of when operation.In addition, this kind of high and low pressure coil arrangement architecture has effectively dwindled the size of coil horizontal direction, and then has dwindled the volume of transformer.
As Fig. 1, described high-tension coil B draws 2 mutually and lifts one's head, and 1 is used for being connected with the tail head of A phase coil, and other 1 is used as high-voltage connection terminal; High-tension coil C draws 2 mutually and lifts one's head, and 1 is used for being connected with the first head of A phase coil, and other 1 is used for A phase connection terminal.Described a phase low-voltage coil is drawn 2 tail heads, is respectively applied for y and is connected with the tail head of b phase, c phase when connecing.This kind of high and low pressure coil mode of lifting one's head has effectively reduced the shared space that goes between, and has dwindled the volume of transformer, and aesthetic in appearance.
Above-described only is preferential execution mode of the present invention.Should be pointed out that for the person of ordinary skill of the art under the situation that does not break away from the principle of the invention, can also make some improvement and modification, this also is considered as protection scope of the present invention.
