Abstract
The utility model relates to an arrangement structure for a large-sized three-phase combined high-impedance transformer, and belongs to the technical field of transformers. The technical scheme is that: a reactor is arranged in the transformer; the transformer comprises an A-phase unit (1), corrugated pipes (2), an on-load tap-changer (3), a B-phase unit (5), a low-voltage phase (5) and a C-phase unit (6), wherein the low-voltage phase and the reactor are arranged in the C-phase unit of the transformer; the on-load tap-changer is arranged in the B-phase unit of the transformer; and the corrugated pipes connect the A-phase unit, the B-phase unit and the C-phase unit, and serve as inter-phase channels for the lead connection and oil-way connection of the three units. The requirements of performance parameters are met, and the anti-short circuit capability of the transformer can be effectively improved; an on-load tap-changer part and the internal reactor are arranged in different units respectively, so that the transport weight and volume of each unit are effectively reduced; and the corrugated pipes are adopted as the inter-phase channels for the lead connection and oil-way connection of the three units, so that the transformer is convenient to disassemble and mount.
Description
Technical field
The utility model relates to a kind of arrangement of large-scale three combined high-impedance transformers, belongs to the transformer technology field.
Background technology
Adopt high-impedance transformer can effectively reduce the system short-circuit electric current, improve the reliability of electrical network, in electric power system, be used widely.Adopt built-in reactor to realize that the high impedance structures of transformer has that structure is simple relatively, economical operation, can effectively improve the anti-short circuit capability of transformer.Because behind the normal transformer built-in reactor; The weight and volume of transformer all can correspondingly increase; For the restricted area of transportation condition, the three-phase high-impedance transformer is difficult to satisfy local demand to high-impedance transformer, when adopting the three-phase combining structure; It is improper to arrange like three cellular constructions, also can make the transformer hard transportation.
The utility model content
The purpose of the utility model provides a kind of arrangement of large-scale three combined high-impedance transformers; When satisfying the performance parameter requirement; Can improve the anti-short circuit capability of transformer, volume is little, hauled weight is light, convenient transportation, be prone to install, and solves the problems referred to above that background technology exists.
The technical scheme of the utility model is: a kind of arrangement of large-scale three combined high-impedance transformers; The transformer built-in reactor; Comprise A facies unit, bellows 2, on-load voltage regulating switch, B facies unit, low pressure mutually 5, the C facies unit, low pressure and reactor are arranged on the C facies unit of transformer, on-load voltage regulating switch is arranged on the B facies unit of transformer; Bellows connects A facies unit, B facies unit and C facies unit, connects the alternate passage that is connected with oil circuit as above-mentioned three unit lead-in wire.
Transformer integral body is provided with an on-load voltage regulating switch, carries out pressure regulation.
The good effect of the utility model: the utility model is phase three-wire three circle combination on-load voltage regulation power transformer; When satisfying the performance parameter requirement; Can effectively improve the anti-short circuit capability of transformer,, effectively alleviate the hauled weight and the volume of individual unit because the on-load voltage regulating switch part is arranged in different unit with built-in reactor; Adopt bellows to connect the alternate passage that is connected with oil circuit, can make things convenient for the user to dismantle to greatest extent and install as the lead-in wire of three unit.
Description of drawings
Accompanying drawing 1 is the utility model sketch map;
Among the figure: A facies unit 1, bellows 2, on-load voltage regulating switch 3, B facies unit 4, low pressure phase 5, C facies unit 6.
