Transformer station secondary cable laying and cleaning protective device

Abstract

The invention provides a transformer station secondary cable laying and cleaning protective device including a mount, a clamping cleaner, and a combination connecting piece, the mount includes a body, a connecting piece, a connecting bolt, a clamping screw rod, and a clamping block, the connecting piece is connected with the body through the connecting bolt, the clamping screw rod is arranged on the connecting piece, the clamping block is connected with one end of the clamping bolt, the clamping cleaner includes a frame, a first screw rod, a second screw rod, a first extension spring, a second extension spring, a first roller brush, and a second roller brush, the first roller brush and the second roller brush are arranged on the frame through the first screw rod and the second screw rod respectively, and the first extension spring and the second extension spring connect the first screw rod and the second screw rod. When the protective device is used, the clamping cleaner is fixedly connected with the mount through the combination connecting piece. The protective device provided is simple in structure, low in cost, and convenient to carry and install; and moreover, when the protective device is used, the protective device can effectively protect civil engineering and electric equipment of a new building transformer station; and meanwhile, the protective device can further protect and clean a secondary cable itself.

Description

technical field [0001] The invention relates to the field of substation construction auxiliary facilities, in particular to a cleaning protection device for secondary cable laying in a substation. Background technique [0002] Before laying the secondary cables (control cables) in the new substation, the civil work of the substation should have been completed, the doors, windows, railings, etc. of the civil work have been installed, and most of the protective screen cabinets and related electrical equipment of the substation have been installed in place; Cable brackets such as cable groove steel and angle iron for secondary cable laying have also been installed. Therefore, the working site environment for secondary cables in substations is complicated when laying them. , so the laying workload is relatively large. When laying secondary cables in common substations, the secondary cables are usually dragged directly on the ground for construction. Since there is no correspond...

Problems solved by technology

[0002] Before laying the secondary cables (control cables) in the new substation, the civil work of the substation should have been completed, the doors, windows, railings, etc. of the civil work have been installed, and most of the protective screen cabinets and related electrical equipment of the substation have been installed in place; Cable brackets such as cable groove steel and angle iron for secondary cable laying have also been installed. Therefore, the working site environment for secondary cables in substations is complicated when laying them. , so the laying workload is relatively large

When laying secondary cables in common substations, the secondary cables are usually dragged directly on the ground for construction. Since there is no corresponding auxiliary laying device, the secondary cables for dragging construction are dragging through the corners, windows, and railings of the substation on the one hand. Sometimes it will cause wear and tear to the civil foundation of the substation. On the other hand, it will cause wear and tear to the exterior paint of the newly installed substation protection screen cabinet and related electrical equipment. During the dragging process where the cabinet and the cable bracket are in contact, the outer insulation of the secondary cable itself will also be damaged, and because the secondary cable is dirty during the dragging process, it is not easy for the staff to find if it is damaged, thus giving Potential safety hazards after the substation is put into operation
