Abstract
The invention discloses a transformer substation door frame insulating supporting column hanging system which comprises a plurality of disc insulators. The disc insulators are connected in series through tension-resistant connecting lines to form a suspension insulator tension-resistant string. A groove arc plate is arranged on the lower side of the suspension insulator tension-resistant string. A plurality of limiting columns are arranged on the upper side of the suspension insulator tension-resistant string. The limiting columns and the groove arc plate are installed on the same outer side face A of a hoisting frame at the same time. A plate body is bent to form a groove plate, then the groove plate is bent in the direction away from a groove opening, and therefore the groove arc plate is formed. The suspension insulator tension-resistant string is placed in a groove of the groove arc plate. The axes of the limiting columns are perpendicular to the surface of the outer side face A. The limiting columns are located between adjacent disc insulators. The transformer substation door frame insulating supporting column hanging system has the advantages of being simple in structure, easy to operate, high in safety and high in operation efficiency.
