The pressure equalizing ball of high voltage bushing is not completely separated from the bushing, or even though it is completely separated from the bushing, the voltage obtained by capacitive voltage dividing is not enough to break down the oil gap, and it is impossible to produce voltage-type partial discharge.When oil gap braces are used to form interlayer insulation, the braces must be evenly placed along the circumference, so corresponding technological measures must be taken to keep the distance equal.If the lower end of the magnetic isolation groove is lower than the upper edge of the lower clamp, cardboard should be inserted between the pulling board and the lower clamp to isolate the lower end of the magnetic isolation groove from the lower clamp.For example, cable paper is used as a layer on the surface of the winding and glass cloth is used to tie the end of the winding to the lower end of the winding. Then a layer of semi-stacked winding is formed from the lower end. At the same time, a sign is placed in the middle of the winding side of the leading end, indicating the work number, product type, drawing number, phase number, operator name and manufacturing date.The winding of high-pressure cylinder winding is mostly made of circular wire.
    
     (3)4、2、4换位法本方法以总匝数的四分之一为中心,将导体分成四组,每组之间进行一次标准换位,而组中导体的位置不变,然后将导体分成两组,每组中导体的麻木相同。根r,以总匝数的12个位置为中心,在每组导体之间进行一次标准换位,然后将导体分成四组,根数相等,为38。该组中导体的状态保持不变。
    
     立式绕线机运行平稳。反向绕组相对简单,易于径向张紧。由于线段平整,反向张紧时匝间摩擦小,克服了水平绕组机绕组段自重引起的匝间摩擦大的缺点。采用380~380变压器绕组,绕组自重也可自行收紧,绕组安装过程省略,采用立式绕组机绕制连续绕组的方法与卧式绕组机绕制连续绕组的方法基本相同。主要区别在于反向截面的卷绕方法。
    
     图4-56所示的绕组与连续绕组的区别在于匝数分布,连续绕组的匝数顺序为1、2、3,……缠绕绕组的匝数顺序为1,(m2)+1、2,(n2)+2、3,(m2)+m,其中n是每对线段的线匝数,M是序列数。线匝数。用于缠绕缠绕段的导体数量等于该匝数上平行导体数量的两倍。
