Abstract
The invention discloses a winding wire connection structure of a single-phase distyle type reactor. An initial end head is led out from a column A winding. The winding wire connection structure is characterized in that: the upper end part and the lower end part of the column A winding are connected with the middle part of a column X winding after parallel connection; and the upper end part and the lower end part of the column X winding are led out as a tail end head after parallel connection. Relative to the column A, the winding type of the column X winding is simplified from a full knotting cake type with greater manufacturing difficulty to a knotting continuous type structure so as to simplify the winding process of winding and shorten the winding time. An end part insulation structure can save the use number of insulation molded parts. The number of molded parts used in the column X winding is much less than that of the molded parts used in the column A winding, and therefore the manufacturing cost of column X winding is also lower than that of the column A winding.
Description
Technical field
The present invention relates to the winding connection structure of a kind of 750kV of being used for and above single-phase queen post reactor.
Background technology
In the ac high-voltage power transmission and transformation system; Because the head effect of long-distance transmission line all adopts reactor to carry out the compensation of reactive power on transmission line, to weaken the effect of capacitive charging current; Simultaneously; Reactor can also suppress the rising of circuit light hours power-frequency voltage, reduces the overvoltage insulation protection level of circuit, thereby ensures the operation of power grid security, stable, high-quality.The normal reactor that adopts the large capacity single pole structure in ac high-voltage power transmission and transformation system in the past.And surpass, UHV transmission net voltage is high, the reactor capacity is big, and this kind structure then can not satisfy movement requirement, security reliability is poor if adopt.
Summary of the invention
The purpose of this invention is to provide the winding connection structure of a kind of 750kV of being used for and above ultra, the single-phase queen post reactor of ultra high voltage, can solve the existing existing problem of open side type reactor.
For reaching above purpose, the present invention takes following technology side by being achieved:
A kind of winding connection structure of single-phase queen post reactor, head end are lifted one's head and are drawn from A post winding middle part, it is characterized in that, link to each other with the middle part of X post winding after the upper end of A post winding and the bottom parallel connection; Lift one's head as end after the upper end of X post winding and the bottom parallel connection and draw.
In the such scheme, described end is lifted one's head and is drawn from the fuel tank top through grounding sleeve, and through neutral point reactor ground connection.Described A post winding is for be entangled with cake formula winding structure entirely; X post winding is for being entangled with the continous way structure.The bottom of said X post winding is simple core insulation structure.
The invention has the advantages that: owing to draw ground connection after the upper and lower end parallel connection of X post; Therefore upper and lower end parts is low to the insulation level of iron yoke; Its biggest advantage is that the coiling pattern of X post winding is greatly simplified, i.e. the coiling pattern of X post winding is reduced to by the bigger cake formula of being entangled with entirely of manufacture difficulty and is entangled with the continous way structure; Make the winding technique work simplification, the coiling time shortens.Also can simplify the overhang insulation structure simultaneously, reduce insulation molding part's usage quantity, X post molded part usage quantity consumption with respect to the A post reduces a lot.The difficulty of processing of X post winding and manufacturing cost all decrease than A post winding like this.Moreover the center-to-center potential difference is 50%, and reliability is high concerning the long-time running of product.The unforeseeable technique effect of the present invention is that the single-phase queen post reactor of this structure is successfully applied in the megavolt high voltage power transmission electrical network first in addition.

Embodiment
As shown in Figure 1, reactor of the present invention is the queen post structure, and core construction adds two return yokes by two stems and goes up lower yoke and form.Two stems are respectively installed with A post winding 1, X post winding 7 outward.For above-mentioned reactor with queen post winding; There is following structure in line between first terminal outlet and the two post windings: head end is lifted one's head the 2 middle part A from A post winding 1 and is drawn; A post winding upper end 3 links to each other with X post winding middle part 4 with 9 parallel connection backs, bottom; X post winding upper end 5 lifts one's head 6 with 8 parallel connection backs, bottom as end, and X draws from the fuel tank top through grounding sleeve, and through neutral point reactor ground connection.Therefore upper and lower end parts is low to the voltage of yoke, and upper and lower end parts voltage can make the coiling pattern of X post winding and overhang insulation structure greatly simplify after reducing.The relative A post of the coiling pattern of X post winding is reduced to by the bigger cake formula of being entangled with entirely of manufacture difficulty and is entangled with the continous way structure, makes the winding technique work simplification, and the coiling time shortens.The schematic diagram of present embodiment wiring construction is as shown in Figure 2.
As shown in Figure 3; Overhang insulation structure (is example with the lower end) according to the X post winding 7 of Fig. 1 wiring construction and Fig. 2 connection principle can be reduced to the simple ferrous yoke insulation system of being made up of cross-over block 10 (cardboard cushion block), because the effect of insulation molding part is to increase the creepage distance of winding to the iron yoke, as previously mentioned; Because X post winding overhang is to the reduction of iron yoke 11 voltages; Creepage distance to iron yoke 11 requires also to reduce relatively, so insulation system can all save insulation molding part, and relative A post; Can save the insulation forming tube that two covers are lifted one's head up and down, also save the two covers insulation moulding dihedral ring at two ends up and down.
