Abstract
The utility model relates to a matching type supporting plate for fixing a low tension coil in a transformer. The transformer comprises an iron core and the low tension coil sleeved on the iron core, wherein, supporting plates are arranged between the iron core and the low tension coil, the supporting plates are arranged in the height direction of the iron core, the supporting plates are arranged in pairs, each pair of supporting plates is arranged in symmetry to the axial line of the iron core and comprises at least one matching type supporting plate, the matching type supporting plate comprises a first supporting plate and a second supporting plate matched with the first supporting plate, and the first supporting plate is provided with a groove for being matched with the second supporting plate. When the first and the second supporting plates are matched with each other, the second supporting plate is positioned in the groove. The utility model has the following benefits: the number of supporting plates is reduced, thereby making supporting plate installation more efficient; the air gap area between the iron core and the low tension coil is increased, thereby facilitating transformer cooling; and the supporting plates provide excellent protection for the insulation layer on the inner surface of the lower tension coil in the transformer.
Description
Technical field
The utility model relates in a kind of transformer the fitting-type fagging that fixing low-voltage coil is used.
Background technology
At present, between the iron core of transformer and low-voltage coil, can insert fagging usually, its objective is coil is played a supporting role, to realize balance support.
In the prior art, at first can be on iron core sheathed low-voltage coil, low-voltage coil is sheathed to be adjusted to only position after good, and adopt the fagging shown in Fig. 3～5 directly to squeeze into from the position, space of iron core 1 ' and low-voltage coil 2 ', make low-voltage coil 2 ' stretching on iron core 1 ', as shown in Figure 6.Squeezing between iron core 1 ' and the low-voltage coil 2 ' of two fagging symmetries in general, and perpendicular squeeze into four in twos the faggings of symmetry to guarantee its stability.But fagging is easy to cause the broken ring of low-voltage coil inner surface insulating barrier in the strike process; In addition,, also just blocked contacted four faces of iron core and low-voltage coil, the heat radiation of transformer has been affected because fagging is provided with two pairs.
Summary of the invention
The fitting-type fagging that the utility model provides in a kind of transformer fixing low-voltage coil to use.
For achieving the above object, the technical solution adopted in the utility model is:
The fixing fitting-type fagging used of low-voltage coil in a kind of transformer, described transformer includes iron core, be set in the low-voltage coil on the described iron core, be provided with fagging between described iron core and the low-voltage coil, described fagging is along the short transverse setting of described iron core, described fagging is provided with in pairs, each is to the axial line symmetry of the described relatively iron core of described fagging, at least be provided with a fitting-type fagging in a pair of described fagging, described fitting-type fagging comprises first fagging, second fagging that matches with described first fagging, described first fagging is provided with the groove that is used to cooperate described second fagging, when described first fagging matched with second fagging, described second fagging was positioned at described groove.
Preferably, described fagging is provided with a pair of.
Further preferably, be provided with a fitting-type fagging in a pair of described fagging.
Further preferably, another described fagging is second fagging.
Preferably, the end of described second fagging is provided with guiding surface.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, reduces the quantity of fagging, improved the operating efficiency when fagging is installed;
2, increased air gap area between iron core and the low-voltage coil, positive effect has been played in the heat radiation of transformer;
3, when fagging is installed, low voltage winding in transformers inner surface insulating barrier has been played good protective action.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
The fixing fitting-type fagging 4 of low-voltage coil 2 usefulness in a kind of transformer as shown in Figure 1, wherein: transformer includes iron core 1, is set in the low-voltage coil 2 on the iron core 1, be set in the high-tension coil 3 on the low-voltage coil 2, be provided with fagging between iron core 1 and low-voltage coil 2, this fagging is along the short transverse setting of iron core 1.Fagging all is provided with in pairs in general, and each is to the axial line symmetry of the relative iron core 1 of fagging.At least be provided with a fitting-type fagging 4 in a pair of fagging, this fitting-type fagging 4 comprises first fagging 5, second fagging 6 that matches with first fagging 5.First fagging 6 is provided with the groove 7 that is used to cooperate second fagging 6, as shown in Figure 2.In the present embodiment, fagging only is provided with a pair of, and a fitting-type fagging 4 is set in a pair of fagging, and another then adopts second fagging 6.
In addition, an end of second fagging 6 is provided with the guiding surface of conveniently squeezing in first fagging, 5 grooves 78, shown in Fig. 3～5.
Below the concrete method of operation of present embodiment down of setting forth:
At first with one first fagging 5 and second fagging 6 along symmetrical the tying up on iron core 1 of the short transverse of iron core 1, sheathed low-voltage coil 2 on the iron core 1 that is tied with first fagging 5 and second fagging 6, sheathed high-tension coil 3 on low-voltage coil 2, behind the position of adjusting low-voltage coil 2 and high-tension coil 3, second second fagging 6 is driven into by guiding surface 8 in the groove 7 of first fagging 5, with low-voltage coil 2 stretchings.So both the inner surface insulating barrier to low-voltage coil 2 had played good protective action, also original fagging quantity was reduced to two, when guaranteeing its stretching intensity, had also increased the space between iron core and the low-voltage coil, helped the heat radiation of low-voltage coil.
