The invention relates to a capacitive voltage-dividing structure and gas-insulated metal-enclosed power transmission equipment. The gas-insulated metal-enclosed power transmission equipment comprises the capacitive voltage-dividing structure; the capacitive voltage-dividing structure comprises a high-voltage conductor, a shell, a low-voltage polar plate and an intermediate polar plate, wherein an axial line of the high-voltage conductor extends in the left and right direction; the shell allows the high-voltage conductor to be mounted leftwards and rightwards in a penetrating manner; the low-voltage polar plate is arranged on one side of the high-voltage conductor in the radial direction; the intermediate polar plate is arranged between the high-voltage conductor and the low-voltage polar plate; the low-voltage polar plate is hermetically and fixedly connected with the shell. The capacitive voltage-dividing structure provided by the invention is equivalent to a voltage transformer in the prior art; as the intermediate polar plate and the low-voltage polar plate are arranged, compared with the prior art that a high-voltage arm capacitor needs to be separately arranged, the capacitive voltage-dividing structure has the benefits that by using the original high-voltage conductor and the shell, the volume of the capacitor voltage transformer is greatly reduced; the structure is simple, and the production cost is reduced.
