Description

Technical Field

[0001] The utility model belongs to the technical field of power distribution networks, and in particular relates to an insulating shielding protective device used for non-stop power supply operations in power distribution networks. Background Art

[0002] In existing electrical distribution systems, copper busbars are widely used for power distribution due to their excellent conductivity and mechanical strength. As the primary power distribution path within distribution cabinets, the stability and safety of copper busbars are crucial to the reliability of the entire power system. During power system operation, arcing can occur between copper busbars or between copper busbars and other conductive components due to overcurrent, aging equipment, improper installation, or other electrical faults.

[0003] Publication number "CN219144871U" discloses an insulating shielding protective device for non-stop power supply operations in distribution networks. It uses an insulating baffle to shield the arc generated between the copper bars. The insulating blanket is pulled out from the handle, and then the hook is hung on the copper bar. The insulating blanket is wrapped around the live body, so that the live body can be wrapped to prevent the operator from contacting the live body and ensure the safety of the operator. By rotating the bidirectional screw, the two splints can be driven to move relative to each other along the sliding rod, so that the splint can be clamped on the cross arm, thereby fixing the position of the insulating baffle.

[0004] In actual use, insulating barriers are placed in positions corresponding to the copper busbars to shield arcs generated between the copper busbars. However, the size of the insulating barriers is fixed, which means they cannot be adjusted to accommodate copper busbars of different sizes. Since the size and configuration of copper busbars can vary greatly in different electrical distribution systems, fixed-size insulating barriers cannot effectively shield all possible copper busbar gaps, thus limiting their applicability and flexibility.

[0005] In order to solve the above problems, the present application proposes an insulating shielding protective gear for non-stop power supply operations in distribution networks. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

By rotating the bidirectional screw, the two clamps can be driven to move relative to each other along the sliding rod, so that the clamps can be clamped on the cross arm, so that the position of the insulating baffle can be fixed. In actual use, the insulating baffle is placed at a position corresponding to the copper bar, and the arc generated between the copper bar is shielded by the insulating baffle. The size of the insulating baffle is fixed, which means that they cannot be adjusted according to copper bars of different sizes.
