Abstract
The utility model discloses a three-phase power transformer, comprising a pressure relief valve, a low-voltage terminal, a high-voltage terminal, a sealing adhesive rope, a shell, an oil drain valve, a base, an iron core and a coil, wherein the iron and the coil are fixed in the shell, the high-voltage terminal and low-voltage terminals are arranged at the upper part of the shell of which the lower part is provided with the base, the iron core is set to be of an annular closed structure, the three-phase coil is respectively wound on the iron core at uniform interval of 120 degrees, a high-voltage coil tap is connected to the high-voltage terminal, and a low-voltage coil tap is connected to the low-voltage terminal. The three-phase power transformer has the characteristics of higher efficiency, smooth and steady operation, lower noise, less faults and the like.
Description
Technical field:
The utility model belongs to the three-phase power transformer technical field.
Background technology:
Three-phase transformer is the combination of three identical capacity single-phase transformers, is widely used in electric power and carries and power consumer.It has three iron core column, and each iron core column is around two coils of same phase, and one is high-tension coil, and another is low-voltage coil.The three-phase voltage amplitude equates, frequency equates, 120 ° of phase place mutual deviations, and voltage between phase and phase is line voltage, is called phase voltage mutually and between center line.Current three-phase power transformer consists of iron core, coil, housing, high tension terminal, low tension terminal, fuel outlet valve, pressure relief valve etc., iron core is added and is made frame structure by the magnetic conduction silicon steel sheet stack, divide three iron core column and Double layer iron yoke, three-phase coil is wrapped in respectively on three iron core column, iron core and coil are fixed on enclosure interior, high tension terminal and low tension terminal are arranged on housing top, and inside is filled with transformer oil.The use for a long time of this version can cause the iron core seam crossing loosening, produces noise, causes eddy current to increase, and no-load loss is higher; Because three coil positions are not the full symmetric settings, operational environment is also variant in addition, and the inadequate uniform balance of operating state, easily produce fault.
The utility model content:
The purpose of this utility model is to provide that a kind of efficiency is higher, stable working, noise is lower, fault is less three-phase power transformer,
To achieve these goals, the utility model comprises: pressure relief valve, low tension terminal, high tension terminal, gummy cord for sealing, housing, fuel outlet valve, base, iron core, coil, iron core and coil are fixed on enclosure interior, high tension terminal and low tension terminal are arranged on housing top, lower housing portion is provided with base, it is that iron core is set to circular closing structure, 120 °, the even interval of three-phase coil is wrapped in respectively on iron core, high tension terminal is received in the high-tension coil tap, and low tension terminal is received in the low-voltage coil tap.
Like this, the three-phase coil of transformer inside shares a circular iron core, and the length of magnetic path is in full accord and distance is shorter, saves material; Operational environment is the same, the operating state relative equilibrium, and efficiency is higher, failure rate is lower.Due to iron core be closed-loop structure without seam, descend in working order eddy current less, so noise is very low, can also reduce no-load loss.Have the characteristics such as energy conversion efficiency is higher, stable working, noise is lower, fault is less.
The accompanying drawing explanation:
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is external structure schematic diagram of the present utility model.
Fig. 2 is coil winding core structure schematic diagram of the present utility model.
Embodiment:
As seen from Figure 1, Figure 2, the utility model comprises: pressure relief valve 1, low tension terminal 2, high tension terminal 3, gummy cord for sealing 4, housing 5, fuel outlet valve 6, base 7, iron core 8, coil 9.Iron core 8 is fixed on housing 5 inside with coil 9, and high tension terminal 3 is arranged on housing top with low tension terminal 2.Housing 5 bottoms are provided with base 7, fix for integral body.Iron core is set to circular closing structure, during actual fabrication, adopts steel coil strip to press one-shot forming.120 °, the even interval of three-phase coil 9 is wrapped in respectively on iron core 8, and during actual the winding, low-voltage coil is wrapped in inside, and high-tension coil is wrapped in outside.For the larger transformer of power, need to fin be set at the housing outer wall, prevent the housing temperature rise.High tension terminal is received in the high-tension coil tap, and low tension terminal is received in the low-voltage coil tap.Pressure relief valve 1 is too high be used to preventing internal pressure, and fuel outlet valve 6 is be used to changing transformer oil, and gummy cord for sealing 4 is tightly connected for the housing top and the bottom.The utility model can be made series of products as required.
