Embodiment Construction

[0055] The preferred technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0056] In transmission lines, especially in DC lines, the length of the insulator jumper string is relatively long (usually about 9 meters), and due to the angle of rotation, the length of the arm of some inner corners is shorter than the length of the insulator jumper string. According to the structural characteristics of the short arm cross arm, a top-closing type ground wire melting ice automatic wiring device was developed.

[0057] As shown in the figure, the top-closing type ground wire melting automatic wiring device of the present invention includes a top-closing electric pick-up 1, a transmission mechanism 2, an opening and closing conductor 3, a drop-type protective cover 4 and an electrical control system. The transmission mechanism 2 is installed on On the platform on the side of the tower body 5, one end of the openin...

Abstract

The invention discloses an upper-closing type automatic wiring apparatus for ground wire ice-melting. The apparatus is composed of an upper-closing type power taking device, a transmission mechanism, an opening-closing conductive device, a down-falling protection cover, and an electrical control system. The transmission mechanism is arranged on a platform at the side of a tower body. One end of the opening-closing conductive device is connected with a flange plate at the output end of the transmission mechanism and the other end is provided with an adjustable contact. The upper-closing type power taking device is installed a jumper overhanging wire clamp of an insulator jumper string and a plurality of hinging type wire clamps of the upper-closing type power taking device are connected with split wires respectively. The down-falling protection cover is installed on the platform at the outer side of the tower body and is arranged below the transmission mechanism. The electrical control system controls opening or closing of the opening-closing conductive device. The upper-closing type automatic wiring apparatus is applied to a power transmission line needing ground wire ice melting. When the cross arm of the iron tower is shorter than the jumper string, the apparatus is employed.

Description

technical field [0001] The invention relates to the technical engineering field of overhead power transmission lines, in particular to a top-closing type ground wire melting automatic wiring device. Background technique [0002] In the cold winter, some transmission lines in southern my country are prone to icing. Uneven icing on conductors and ground wires will cause the tower to tilt or bend. When the design capacity is exceeded, conductors and ground wires will break, hardware will fall off, etc., which will seriously cause the tower to collapse. The overhead ground wire is not like a wire that can resist partial freezing through the heat generated by the load current, and its ice thickness is generally far greater than that of the transmission wire. [0003] In January 2008, the collapse of the iron tower caused by the large-scale icing of the transmission line in southern my country is still fresh in everyone's memory. [0004] In February 2008, the China Southern Pow...
