AN APPARATUS OF TENSION RELIEF USING POWER ELECTRIC TRANSMISSION

摘要

A tension regulation apparatus for power transmission tower of an overhead electric wire for power transmission is provided to prevent the disconnection of the overhead electric wire by controlling the tension of the overhead electric wire according to the season. A tension regulation apparatus for power transmission tower of an overhead electric wire for power transmission includes an electric wire gradient measurement unit(10) and a tension regulation unit(20). The electric wire gradient measurement unit includes a case, a controller, and an angle sensor. The angle sensor is installed at a front end and a rear end of the inside of the case. The angle sensor measures a gradient of a connecting member(3). The tension regulation apparatus controls tension of a power cable by controlling the length of the connecting member according to the measured result of the electric wire gradient measurement unit. The tension regulation apparatus includes a box body(21), an elevating gear(22), a connecting gear(23), a worm gear(25), a worm(27), a motor, an elevating rod(24), and a roller pole(30). An axial hole is formed in a bottom part of the box body. The elevating gear is engaged with the elevating rod. The connecting gear is engaged with two elevating gears. The worm gear is engaged with the connecting gear. The worm is engaged with the worm gear. The motor transfers rotatory power to a rotary shaft of the worm. The elevating rod is moved within an elevating hole according to the rotation of the elevating gear. The roller pole is rotatably fixed to both sidewalls of the inside of the box body.
