Abstract
The utility model is a transformer coil wiring structure with low-voltage coil wound on the core and then high-voltage coil on the periphery of low-voltage coil. Two high-voltage coils are in series connection, that is, the tail end of the high-voltage coil I is communicated with the head end of the low-voltage coil II, and the head end A of the high-voltage I and the tail end X of the high-voltage II are respectively the input terminal and the output terminal of the high-voltage coil. The tail ends of four low-voltage coils III, IV, V and VI are communicated as the common end X. The head ends of the low-voltage coils III and V are communicated as the common head end a2. The utility model provides a dual-supply transformer coil wiring structure with small load loss and energy conservation.
Description
Affiliated technical field
The utility model relates to a kind of transformer coil wiring construction, belongs to the transformer equipment technical field.
Background technology
In the 6-10KV of electric power system single-phase transformer, as shown in Figure 1, the general mode of connection is that high and low pressure is in parallel respectively, and under this mode of connection, power supply all is single supply output.When half of power supply is exported, i.e. during a1-x or a2-x output, high-tension coil has only monolateral working.This mode of connection load loss is big, the power supply waste is many.
Summary of the invention
The purpose of this utility model is the deficiency at above-mentioned technology, and the transformer coil wiring construction that a kind of load loss is little, the duplicate supply of energy energy savings is exported is provided.
The technical solution of the utility model is: a kind of transformer coil wiring construction, first coiling low-voltage coil on insulation framework, the coiling high-tension coil again in the low-voltage coil periphery.High-tension coil adopts cascaded structure, and promptly the tail end of high-tension coil I is connected with the head end of high-tension coil II, and the head end A of high-tension coil I and the tail end X of high-tension coil II are respectively input, the output of two high-tension coils.The tail end of low-voltage coil III, low-voltage coil IV, low-voltage coil V and low-voltage coil VI is connected as the common tail end x of four low-voltage coils.The head end of low-voltage coil III and low-voltage coil V is connected as the common head end a1 of these two low-voltage coils.The head end of low-voltage coil IV and low-voltage coil VI is connected as the common head end a2 of these two low-voltage coils.
The utility model has the advantages that when the sub-a1 of low-voltage output and x or a2 and x combined during as lead-out terminal then two output voltages be 220V.When a1 and a2 combined during as lead-out terminal then output voltage be 440V.Realized the purpose of two kinds of power supply outputs from above the utility model as can be seen.
Another advantage of the present utility model is when half of power supply is exported, and when a1-x or a2-x output, all work in the high-tension coil both sides.Compared with prior art, when passing through same capacity, the load loss of high-tension coil has only half.So just realized that load loss is little, the purpose of energy energy savings.
The utility model is described in further detail below in conjunction with drawings and Examples.
