摘 要：依據(jù)在變壓器繞組對地介質(zhì)損耗因數(shù)測量項目中，同時測得的不同接線方式下繞組對地電容量的測量結(jié)果，通過闡述各繞組對地混聯(lián)電容量與各側(cè)繞組單獨對地電容量和相鄰繞組之間電容量的相互關系，分別對雙繞組變壓器和三繞組變壓器在不同繞組排列方式下各側(cè)繞組單獨對地電容量和相鄰繞組之間電容量的間接測量方法進行了分析，可知不同的繞組排列結(jié)構(gòu)，各側(cè)繞組單獨對地的電容量和相鄰繞組之間的電容量并不相等。

Abstract: According to the measurement results of the winding-to-ground capacitance under different wiring modes measured at the same time in the transformer winding dielectric dissipation factor measurement project. By expounding the relationship between the mixed capacitance of each winding-to-ground and the capacitance of each side winding-to -ground alone and the capacitance between adjacent windings,the indirect measurement methods of the capacitance of each side winding-to-ground alone and the capacitance between adjacent windings under different winding arrangement modes of double-winding transformer and three-winding transformer are analyzed respectively. It can be seen that the capacitance of each side winding to the ground alone and the capacitance between adjacent windings are not equal in different winding arrangement structures.
