Abstract
The utility model relates to a transformer end screen grounding detection device. A fixed member is connected with a pedestal. A protective cover is sleeved on the fixed member. A cable cover is sleeved on the protective cover. The upper end face of the fixed member is connected with an end screen protective circuit board which is arranged in the protective cover. The end screen protective circuit board is provided with a clamp sleeve and a contact. The clamp sleeve is sleeved on the contact. The bottom of a circular groove of the fixed member is provided with an insulated pad. A hole of the insulated pad is provided with a conducting rod. One end of the conducting rod passes through the hole in the insulated pad to contact with the contact. The upper end of the contact is provided with a terminal. A water-proof joint is arranged in the cable cover. The beneficial effects are that: the clamp sleeve can move up and down, so the complete contact between the contact and the conducting rod is guaranteed; the contact face is cylindrical, so the connection effect is excellent; the installation position of the clamp sleeve has a certain distance from the pedestal, so the contact face between the contact and the conducting rod can be seen directly, and under the power-off condition, whether or not the contact is electrically connected with the conducting rod can be checked up.
