QUICK-MOUNTED SUPPORT OF OVERHEAD POWER TRANSMISSION LINE WITH HORIZONTAL ARRANGEMENT OF PHASE CONDUCTORS FOR EMERGENCY RECOVERY OPERATIONS Russian patent published in 2025 - IPC E04H12/00 

FIELD: electric power industry.

SUBSTANCE: quick-mounted support of overhead power transmission line of portal type with horizontal arrangement of phase conductors for performance of emergency recovery works contains crossbar (3), mounted in upper part of two vertical posts (2), and base (1) formed from four longitudinal pipes (7) and (8), located in pairs on different sides of the axis of the overhead transmission line, and two transverse pipes (9) and (10) located perpendicular to the axis of the power transmission line above said four longitudinal pipes and rigidly attached to them. Each vertical post (2) is connected to base (1) by means of post attachment assembly (16) to the outer longitudinal pipe of the base, which provides the possibility of angular movement of the post along the axis of the power transmission line and perpendicular to it, and two braces (4), which by one end are fixed on corresponding post (2), and the other ends of braces (4) are separated and attached to opposite transverse pipes (9) and (10) of base (1) in the section between pairs of longitudinal pipes (7) and (8), braces (4) are provided with turnbuckles (11) for adjusting the inclination of vertical posts (2). Support is equipped with crossbar (5) formed of two interconnected sections, each of which is pivotally connected to opposite longitudinal inner tubes (8) of base (1), and at the point of connection of crossbar (5) sections, a rigging consisting of two brace wires (6) is attached, for the support installation by the "falling boom" method, wherein free ends of brace wires (6) are fixed on vertical posts (2) below the point of connection of posts with braces (4).

EFFECT: simplification of support design and simplification of its installation.
