The invention relates to a gas-insulated multiple-output electronic post-type current-voltage combined transformer comprising an upper end high-voltage barrel and a lower end combined insulator sleeve. A coaxial capacitive voltage transformer of the combined transformer comprises a voltage-equalizing shield barrel (1), a floating potential tube (6), and a low-voltage capacitive structure; the voltage-equalizing shield barrel (1) and the floating potential tube (6) are disposed in the combined insulator sleeve; the low-voltage capacitive structure is disposed within the floating potential tube (6). The gas-insulated multiple-output electronic post-type current-voltage combined transformer is characterized in that the low-voltage capacitive structure is at least provided with a first metal layer (7), a second metal layer (9), and a third metal layer (11) sequentially from outside to inside; insulating medium is arranged between each two metal layers; the first metal layer (7) is connected to the inner wall of the floating potential tube (6); the second metal layer (9) is in a split structure. The gas-insulated multiple-output electronic post-type current-voltage combined transformer has the function of multiple-output multiple protection, such as dual-output dual protection, and has the advantages of small size, high disturbance resistance, high precision, high reliability, low cost and the like.
