Definitions
- the invention relates to a two- or multi-phase transformer according to the preamble of claim 1.
- the invention relates to dry type transformers or cast resin / Resibloc transformers with corresponding coil supports.
- These coil supports are usually made of plastic, which are arranged below and / or above the coil. They have the main task of carrying the weight of the spool; In addition, measures must be taken to produce a Kriechwegverinrung, which is achieved by glued between items of Spulenabstützungen plates. In particular, when a long creepage distance is required, it may be necessary for a single coil support or coil support block to be glued together to obtain the creepage path extension from many individual parts.
- the object of the invention is to provide a transformer in which the coil is supported by as few support blocks, the generation of a sufficiently long creepage path is simplified.
- At least two support blocks for each coil can be placed on each bearing surface, which are fitted on the coil-side support surface with elastic compensation elements and at their perpendicular to the support surface extending longitudinal side surfaces have at least one creepage extending bar in the longitudinal direction and parallel to the support surface of the support block run.
- a support block which can be produced, for example, in a so-called pultrusion process and in which due to the choice of shape a Kriechwegverinrung is provided from the outset on the longitudinal side surfaces of the support blocks.
- At least one support block at its end faces have at least one in the direction of the support surface and parallel introduced slot, which also serves to extend the creepage distance or path or serve.
- the at least one slot can be mounted outside the region of the strips.
- At least one of the support blocks may be hollow. As a result, a reduction in the amount of required insulating material is achieved; the support block is thereby lighter and due to the inner cavity and stress cracks during curing are avoided.
- the at least one hollow support block may have at least two, preferably three strips, corresponding to the required length of the creepage distance.
- the strand produced in the pultrusion process is shortened, wherein the support block is simply cut to length at the desired length of a long profile.
- the one support block on the contact plane a strip-like projection and the other have a recess adapted thereto, which extend in the longitudinal direction, which fits into the recess of the projection, so that both support blocks through the projection and the Deepening similar to the tongue and groove are guided against each other.
- the height of the support blocks may be different; For example, a profile with a lower height can be used, whereby the height of the composite Abstützblöcke can be adapted to the needs.
- a strip which may consist of elastic material, in particular of a silicone rubber.
- FIG. 1 is a sectional view along section line l-l of Fig. 2,
- FIG. 2 is a sectional view corresponding to section line INI of Fig. 1,
- FIG. 3 is a sectional view similar to that of FIG. 1 with two support blocks
- Fig. 4 shows another embodiment of a support block, in perspective view
- FIG. 5 is a view of a support block for height adjustment, similar to FIG. 4. Reference is made to FIG. 1.
- the support block 15 is shown in detail in FIG. 4.
- the support block 15 has in cross section perpendicular to its longitudinal extent approximately a rectangular shape with a certain height H and a width B, of which the width B is smaller than the height H.
- the support block 15 has an inner cavity 18, whereby a weight reduction and a material reduction is generated.
- the bearing surfaces 19 and 20 are grooves 21 and 22, wherein in the representation shown in Fig. 4 in the groove 21, a centering profile 23 is inserted, which serves to produce an anti-rotation between two superposed support blocks 24 ⁇ and 24 2, see Fig. 3.
- the supporting blocks 24 i and 24 2 of Fig. 3 differ from the supporting block 15 of FIG. 4 in that a cavity 18 is not present ,
- side surfaces 25 and 26 are provided outwardly projecting and extending in the longitudinal direction of the support block 15 strips 27 and 28 which project outwardly from the side surfaces 25 and 26 in the opposite direction, creating a Creepage distance between the coil 17 and the double-T-beams 10, 11 is generated on both side surfaces.
- the corresponding strips of Abstützblöcke 24i and 24 2 are not provided there with reference numerals.
- Fig. 1 shows, in addition to the support block 15, two support blocks 16i and 16 2> which are shown in Fig. 5. They have a width B which corresponds to the width of the support blocks 15, and a height h, which is lower, in certain cases significantly less than the height H of the support blocks. With these support blocks 16i and I6 2 an adjustment of the support blocks to the distance or the distance of the coil from the support surface 14 of the carrier 10, 11 is adjusted.
- the support blocks 16i, 16 2 which may be referred to as shims, have on the upper side (in the drawing) a projection 33 and on the lower side a longitudinally extending, parallel to the projection 33 extending recess 34 which corresponds to the recess 22 ; the projection 33 is dimensioned such that it can engage in the corresponding recess 22 of a further support block placed over the compensating piece 16, as shown in FIG.
- a strip 35 of elastic material in the existing there groove or recess 21 is inserted, preferably a strip of a silicone rubber material, with the possible unevenness of the lower side of the coil 17 are compensated can.
- the strip 35 can have the same dimensions as the centering profile 23.
- Support block i Support block 2
- Support block i Support block 2
