摘 要:變壓器高壓側采用電纜出線,能夠有效減小變電室的空間尺寸,減少建設成本和土地占用。介紹了現(xiàn)有的典型結構設計,分析了其優(yōu)缺點,提出了進一步結構優(yōu)化方案,降低變壓器高度,優(yōu)化引線結構后,取消油油套管出線,變壓器線圈高壓側引線出頭直接連接至電纜插拔頭底座上。實際應用表明,在降低高度的同時簡化了安裝結構,并降低生產制造成本。
關鍵詞:變壓器;電纜插拔頭;優(yōu)化

Abstract: The use of cable outlets on the high-voltage side of the transformer can effectively reduce the space dimensions of the substation, construction costs and land occupation. In this paper the existing typical structural design is introduced, its advantages and disadvantages are analyzed, and further structural optimization schemes are proposed to reduce the height of the transformer. After optimizing the lead structure, the oil bushing outlet is eliminated, and the high-voltage side lead outlet of the transformer coil is directly connected to the cable plug on the head base. Practical application shows that while reducing the height, it simplifies the installation structure and reduces production costs.
Key words: transformer; cable plug; optimization
