Electrical control cabinet

The utility model discloses an electrical control cabinet, comprising a box body, the top of the side wall of which is provided with at least one air outlet window; the transom window is formed in the bottom end of the box body and used for enabling external gas to enter the box body from the bottom; the air draft assembly is arranged in the box body and is used for sucking external air; the top end of the self-gravity baffle assembly is rotationally arranged at the top end of the inner wall of the air outlet window; the self-gravity baffle assembly is used for being opened when gas in the box body is exhausted outwards, and external gas can be prevented from entering the box body from the air outlet window. When the box is used in rainy days, air is exhausted from the bottom of the box body, so that the problem that rainwater enters the box body when air enters the box body from the side part of the box body is avoided; and when the gas is not exhausted, the self-gravity baffle assembly is in a closed state
