The invention provides a hand-hole type capacitive voltage divider comprising a sensing electrode, a hand-hole cover plate and a cable joint. The sensing electrode is fixedly mounted on the hand-hole cover plate, and is electrically connected with the cable joint. An isolation film is arranged between the sensing electrode and the hand-hole cover plate to isolate the sensing electrode from the hand-hole cover plate. The hand-hole type capacitive voltage divider further comprises an isolating board, a first sealing ring and a second sealing ring. The isolating board is arranged between the sensing electrode and the hand-hole type cover plate, the first sealing ring is arranged on a contact surface of the isolating board and the sensing electrode to perform air seal between the isolating board and the sensing electrode, and the second sealing ring is arranged on a contact surface of the isolating board and the hand-hole cover board to perform air seal between the isolating board and the hand-hole cover board. By the arrangement, the problem of low parallel resistance of low-voltage arms of the hand-hole type capacitive voltage divider in the prior art is effectively solved, so that low-frequency characteristic of the hand-hole type capacitive voltage divider is achieved.
