Abstract
The utility model discloses a grounding device of a movable high-voltage switch, which comprises a circuit breaker handcart grounding device and a guide rail grounding device. A guide rail grounding copper bar (4) is arranged in the longitudinal direction of the left and right guide rails (3) of a switch cabinet. The guide rails (3) are connected with a main grounding bar (8) through a flexible connector (5). A duckbilled grounding contact (2) on a circuit breaker handcart (1) is occluded with the guide rail grounding copper bar (4) on the guide rails (3). By adopting the technical scheme, the guide rail grounding copper bar on the guide rails is matched with the duckbilled grounding contact of the circuit breaker handcart. When the circuit breaker handcart moves to a working position from a testing position through a swing mechanism, the guide rail grounding copper bar is tightly occluded with the duckbilled grounding contact through sliding. Thereby, the contact resistance is greatly reduced, the safety of operators is further guaranteed, the requirement on the electrical grounding safety of the switch cabinet is fully satisfied and the sliding grounding of the high-voltage switch is realized.
