Description

Technical Field

[0001] The utility model relates to the field of barrier structures, in particular to a barrier structure of a transformer. Background Art

[0002] Insulating barriers generally refer to insulator devices used in power transmission systems to connect poles, towers and suspension cables that transmit high voltage electricity. They are installed between conductors at different potentials or between conductors and grounded components and can withstand voltage and mechanical stress. There are many types and shapes. Although the structures and appearances of different types of barriers are quite different, they are all composed of two major parts: insulating parts and connecting hardware.

[0003] After searching, the publication number CN110534321A is a transformer insulator, which has the ability to freely retract and discharge wires and can be fixed on the top of the transformer to fix the wires connected to the transformer. The insulator includes a base, and the base includes a horizontal plate and a vertical plate. One side of the horizontal plate is connected to one side of the vertical plate to form an L-shaped plate. At least one mounting plate is fixed to the side of the horizontal plate away from the transformer, and at least one mounting plate is fixed to the side of the vertical plate away from the transformer. A connecting rod perpendicular to the mounting plate is fixed in the middle of the mounting plate, and a wire threading tube perpendicular to the other end of the connecting rod is fixed. A column is arranged at the corner of the base away from the transformer, and the column is perpendicular to the horizontal plate. A wire winding drum that can rotate relative to the column is arranged on the top of the column, and at least one end of the wire threading tube points to the column.

[0004] The appealed technical solution has the following deficiencies:

Replacing a large number of insulating barriers will not only cause a waste of manpower and financial resources, but also make disassembly and secondary installation more troublesome.
