Abstract
The utility model provides a junction device for two serially connected columns of converter transformer valve-side windings. The device comprises iron cores in the two columns in a transformer oil tank, the exterior side of the iron core of each column is provided with a regulating winding, a network-side winding, and a valve-side winding in order from inside to outside, and the mode of connection of the valve-side windings outside the two iron cores is serial connection. The valve-side windings in the utility model adopt a connection mode of serial connection, the two valve-side windings jointly bear impulse voltage, thereby simplifying the inner structure of the valve-side windings, and reducing cost of the converter transformer.
Description
Technical field
The utility model relates to a kind of wiring construction of transformer valve side winding, particularly a kind of termination of valve winding in converter transformer two posts series connection.
Background technology
Along with the continuous development of China's power industry, the increase of the big trans-regional remote DC power transmission line of capacity is had higher requirement to the transmission line capability and the transmission distance of DC power transmission line.Domestic existing converter transformer voltage on valve side is up to ± 800kV; But increase along with transmission line capability and transmission distance; Transmission of electricity economy under the existing voltage will significantly reduce; The electric pressure that needs to improve net side and valve side to improve the economy of direct current transportation like voltage on valve side is ± 1100kV.
Original valve winding in converter transformer adopts the mode of connection (see figure 1) of two posts parallel connection; Lifting along with valve side winding (± 1100kV level) direct voltage; Valve side lightning impulse voltage is also along with raising, and the original valve side adopts the mode of connection of two posts parallel connection to need valve side winding is carried out special Design Treatment, so that valve side winding can satisfy the requirement of lightning impulse test and switching impulse test; Like this; It is very complicated that valve side winding internal structure will become, and makes and require also very harshness, and the manufacturing cost of converter transformer also obviously increases.Simplify valve side Winding Design, the manufacturing cost that reduces converter transformer becomes the problem that needs solution.
The utility model content
The utility model provides a kind of termination of valve winding in converter transformer two posts series connection, simplifies valve side winding construction, reduces the manufacturing cost of converter transformer.
The technical scheme that the utility model adopted is:
A kind of termination of valve winding in converter transformer two posts series connection; Comprise that two posts that are arranged in the oil tank of transformer are unshakable in one's determination; Every post iron core outside is disposed with pressure regulation winding, net side winding, valve side winding from inside to outside, and the valve side winding in two outsides unshakable in one's determination adopts the mode of connection of series connection.
As the preferred embodiment of the utility model, said valve side winding adopts the mode of end outlet, and two valve side windings are connected in series at leading-out terminal;
Preferred embodiment as the utility model; Said every post valve side winding unshakable in one's determination adopts the mode of middle part outlet; Each valve side winding divides two parts up and down; Wherein the top of each valve side winding is connected in series, and the lower part of each valve side winding is connected in series, the top of two valve side windings after the series connection with connect after the lower part of two valve side windings be connected in parallel.
The termination of the utility model valve winding in converter transformer two posts series connection has the following advantages at least: the utility model valve side winding adopts the mode of connection of series connection; Bear surge voltage jointly by two valve side windings; Simplify the internal structure of valve side winding, reduce the cost of converter transformer.

Embodiment
Below in conjunction with accompanying drawing the termination of the utility model valve winding in converter transformer two posts series connection is done detailed description:
The wiring construction of the utility model valve winding in converter transformer two posts series connection; Comprise that two posts that are arranged in the oil tank of transformer are unshakable in one's determination; Every post arranged outside unshakable in one's determination has 1 pressure regulation winding, 1 net side winding, 1 valve side winding, is connected to the valve Room after said 2 valve side windings (1,2) series connection.Above-mentioned each winding in the outside unshakable in one's determination from inside to outside put in order for: pressure regulation winding-net side winding-valve side winding, valve side two posts adopt the mode of connection of connecting.
See also shown in Figure 1; Valve side winding two post series systems one: the wiring construction of valve winding in converter transformer two posts series connection; The a plurality of windings that comprise the two post iron cores outside that is arranged in the oil tank of transformer, each winding are putting in order and be pressure regulation winding-net side winding-valve side winding from the inside to the outside in the outside unshakable in one's determination, in this structure; Employing is with the mode of 2 valve side windings in series; Bear surge voltage jointly by two valve side windings, can simplify the internal structure of valve side winding, reduce the cost of converter transformer.
See also shown in Figure 2; Valve side winding two post series systems two (referring to Fig. 3): the wiring construction of valve winding in converter transformer two posts series connection, comprise a plurality of windings in the two post iron cores outside that is arranged in the oil tank of transformer, each winding is putting in order and be pressure regulation winding-net side winding-valve side winding from the inside to the outside in the outside unshakable in one's determination; In this structure; Valve side winding adopts the middle part outlet structure, and the mode of parallel connection again after being connected respectively in 2 column valve side winding upper and lower parts is born surge voltage jointly by two valve side windings; Can increase valve side winding and two the creepage path between lifting one's head, the outlet of valve side is more flexible.
The utility model is compared with the structure of original valve side winding parallel connection, has the following advantages:
1. valve side winding adopts the mode of connection of series connection, bears surge voltage jointly by two valve side windings, can simplify the internal structure of valve side winding, reduces the cost of converter transformer.
2. can increase valve side winding and two the creepage path between lifting one's head.
3. the outlet of valve side is more flexible.
The above is merely a kind of execution mode of the utility model; It or not whole or unique execution mode; The conversion of any equivalence that those of ordinary skills take the utility model technical scheme through reading the utility model specification, the claim that is the utility model contains.
