Abstract
The utility model discloses a kind of double low-voltage coils of longitudinally staggered formula structure, including high-tension coil, the high-tension coil epimere top side is provided with low-voltage coil a1 a2 terminals, and the high-tension coil hypomere bottom side has low-voltage coil x1 x2 terminals.The utility model is simple in construction, with the low-voltage dual-voltage characteristic for the double transformer with split windings of oil immersed type, and improves its reliability of operation.
Description
Technical field
The utility model belongs to electrical equipment technical field, and in particular to a kind of double low-voltage lines of longitudinally staggered formula structure
Circle.
Background technology
Upper and lower two sections of longitudinal splitting formulas are typically used for the double low-voltage coil structures of the double division distribution transformers of oil immersed type,
That is upper semisection half capacity, lower semisection half capacity, upper and lower two sections of axial heights stack up it is almost contour with high-tension coil,
Each section of electric height is about the half of high-tension coil.This structure is when low-voltage dual-voltage operation simultaneously and load is quite, upper and lower
Two sections simultaneously powered, and suitable with the electric height of high-tension coil, coil ampere-turn is more balanced, transformer uniform force, axial machine
Tool power is small, and when low pressure only has one section of energization or two sections of institute's on-loads seriously uneven, coil ampere-turn is uneven, transformer unbalance stress
Even, axial mechanical force is big, and this can bring greater risk to the safe operation of transformer.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art that there is provided a kind of the double low of longitudinally staggered formula structure
Line ball circle.
In order to reach above-mentioned purpose of design, the technical scheme that the utility model is used is：A kind of longitudinally staggered formula structure
Double low-voltage coils, including high-tension coil, the high-tension coil epimere top side is provided with low-voltage coil a1- a2 terminals, institute
Stating high-tension coil hypomere bottom side has low-voltage coil x1-x2 terminals.
The a1-x1 is one low-voltage coil, and its height is highly suitable with high-tension coil.
The a2-x2 is another low-voltage coil, and its height is highly suitable with high-tension coil.
The high-tension coil is longitudinally staggered formula structure with upper and lower section of low-voltage coil.
The utility model beneficial effect：Using whether low pressure univoltage charging operation or twin voltage after the utility model
While charging operation, the longitudinally staggered formula structure of low pressure can make high-voltage coil and low-voltage coil ampere-turn keep balance, transformer uniform force, axle
It is small to mechanical force.The utility model is simple in construction, with the low-voltage dual-voltage characteristic for the double transformer with split windings of oil immersed type, and carries
Its high reliability of operation.
Brief description of the drawings
Fig. 1 is double low-voltage coil structure schematic diagrames of the longitudinally staggered formula structure of the utility model；
Fig. 2 is double line ball coil structures schematic diagrames of the upper and lower two sections of longitudinal splittings formula structure of prior art.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.As shown in Figure 1-2：A kind of oil
The double transformer with split winding low-voltage coils of immersion, including high-tension coil 1, the epimere top side of high-tension coil 1 are provided with low-voltage coil
A1- a2 terminals 2, the hypomere bottom side of high-tension coil 1 has low-voltage coil x1-x2 terminals 3.
The a1-x1 is one low-voltage coil, and its height is highly suitable with high-tension coil.
The a2-x2 is another low-voltage coil, and its height is highly suitable with high-tension coil.
The high-tension coil 1 is longitudinally staggered formula structure with upper and lower section of low-voltage coil.
When the utility model is used:It is low when whether low pressure univoltage charging operation or twin voltage charging operation simultaneously
Longitudinally staggered formula structure is pressed high-voltage coil and low-voltage coil ampere-turn is kept balance, transformer uniform force, axial mechanical force is small.
