Abstract
The utility model provides a gas-insulated instrument transformer which uses a same part to stop winding a coil and prevent migration, wherein the periphery of a foot portion (1A) of an iron core (1) is provided with a coil winding frame (4) for a primary coil, and the periphery of the coil winding frame (4) for the primary coil is winded with a primary coil (17). The iron core (1) is closely fixed by a core fastening hardware part (6), and the two end portions of the coil winding frame (4) for the primary coil are provided with grooves (15) on side openings of the core fastening hardware part (6). The core fastening hardware part (6) is provided with a coil fixed bolt (16) whose size is above M6. The head portion (16a) of the coil fixed bolt (16) is embedded in the grooves (15) of the coil winding frame (4) for the primary coil to press the coil winding frame (4) for the primary coil.
Description
Technical field
The utility model relates to the gas-insulated instrument transformer, and particularly the coiling of its coil stops the improvement with axial fixed structure.
Background technology
Fig. 5 and Fig. 6 are the figure of existing this kind gas-insulated instrument transformer of expression.Existing gas-insulated instrument transformer, has iron core 1, iron core 1 is by the 1A of foot and meet the 1B of iron portion and form ring-type, the periphery of a 1A of foot of iron core 1 has secondary coil and rolls up frame 2 with coil, secondary coil is rolled up the periphery coiling secondary coil 3 of frame 2 with coil, have primary winding in its periphery and roll up frame 4 with coil, primary winding is rolled up the periphery coiling primary winding (not having diagram) of frame 4 with coil.
Primary winding stops with the coiling of coil volume frame 4, and having in its end reels stops cut part 4a.Coiling stops cut part 4a and is embedded in and connects among the 1B of iron portion.
The 1A of another foot of non-winding line circle and meet the 1B of iron portion is by fastening five metals parts 5,6 clampings of core that angle steel constitutes, fixing with bolt 7,8 and nut 9,10.
The fastening five metals parts 6 of core are being rolled up frame 4 one sides towards primary winding with coil, and fixedly the shielding of low pressure side 11.
The installation of shielding 11 of low pressure side and the fastening five metals parts 6 of core: the band spiral shell that welded and installed is shielded 11 sides in the low pressure side is attacked lug boss 12 and the fastening five metals parts 6 usefulness bolts of core 13 fixing finishing.
In addition, for preventing the skew of primary winding, it is fixing that the fastening five metals parts 6 of core are pushed bolt 14 with coil.
The utility model content
The technical problem that solves
The coiling of primary winding stops to be embedding and connecing that the 1B of iron portion carries out by primary winding is stopped cut part 4a with the coiling of coil volume frame 4 ends, the primary winding skew prevent that pushing bolt 14 by coil carries out.Like this, need device separately, during operation cost.
Be performance function separately, primary winding is rolled up the gap that needs between frame 4 and the fastening five metals parts 6 of core to a certain degree with coil.
Technical scheme
Improvement object of the present utility model is, the periphery configuration coil volume frame in iron core foot, at the periphery coiling coil of coil volume frame, with iron core with the fastening gas-insulated instrument transformer of the fastening five metals parts of core.
Gas-insulated instrument transformer of the present utility model has the groove of the fastening five metals component side of core opening in the end of coil volume frame, the coil stationary bolt that can be installed on the fastening five metals parts of core embeds this groove with advancing and retreat.
At this moment, the size of best coil stationary bolt is more than M6.
In addition, preferably the coil stationary bolt is fixed on its head on the fastening five metals parts of core towards coil volume frame side, and the head of coil stationary bolt is embedded in the groove of coil volume frame.
Beneficial effect
By end the groove of the fastening five metals component side of core opening is set, the coil stationary bolt that is installed on the fastening five metals parts of core is embedded this groove, can prevent simultaneously that coil from rotating and direction of principal axis is fixed and the direction of principal axis adjusted size at coil volume frame.
In addition, by using the coil stationary bolt, can easily carry out the fixing fine setting that reaches the direction of principal axis adjusted size of direction of principal axis of coil.
In addition, the coil stationary bolt is by being fixed in the fastening five metals parts of core with its head towards coil volume frame side, the head of coil stationary bolt is embedded in the groove of coil volume frame, can prevent really that the coil stationary bolt breaks away from from groove, can stably carry out the fixing of coil volume frame.

Embodiment
Fig. 1 to Fig. 4 is the figure of an embodiment of expression gas-insulated instrument transformer of the present utility model.Primary winding has a pair of groove 15 with the both ends of coil volume frame 4 in fastening five metals parts 6 sides of core.This groove is provided with respectively in 180 ° of different positions of circumferencial direction.In addition, coil stationary bolt 16 is rolled up frame 4 sides towards primary winding with coil with its head 16a, is fixed on the fastening five metals parts 6 of core.The head 16a of coil stationary bolt 16 embeds in the groove 15 of primary winding with coil volume frame 4.
Like this, the groove 15 of fastening five metals parts 6 side openings of core is set by the end at coil volume frame 4, the coil stationary bolt 16 that is installed on the fastening five metals parts 6 of core is embedded the groove 15 that coil is rolled up frame 4, can prevent simultaneously that primary winding 17 from rotating and direction of principal axis is fixed and the direction of principal axis adjusted size.18 is high-tension shieldings in addition.
In addition, consider the required intensity of coil stationary, the coil stationary bolt uses the above size of M6.
