Embodiment Construction

[0023] The preferred technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] As shown in the figure, the flexible ground wire melting ice wiring device of the present invention, which can melt the ground wire ice in any small section of the iron tower, includes a contact 1, an insulating rod 2, an overcurrent wire 3 and a rotating chuck 4 , The contact 1 is installed at the end of the head of the insulating rod 2, the contact 1 is also connected with an overcurrent wire 3, and the tail of the insulating rod 2 is installed with a rotating chuck 3.

[0025] The contact 1 includes a contact finger 1-1, a card slot 1-2 and an over-current block 1-3. An over-current block 1-3 is installed under the card slot 1-2, and symmetrically installed on both sides of the over-current block 1-3. Multiple pairs of contact fingers 1-1, multiple pairs of contact fingers 1-1 are arranged side by side, the insulating ro...

Abstract

The invention discloses a flexible ground wire ice melting wiring apparatus which comprises a contact, an insulating rod, an over-current wire and a rotary clamping head, wherein the contact is installed on the head end portion of the insulating rod, the over-current wire is connected on the contact, and the rotary clamping head is installed on the tail portion of the insulating rod. The contact clamps a lead, the rotary clamping head fixes the insulating rod on an iron tower, and the other end of the over-current wire is connected with a ground wire. Current flows to the ground wire after passing through the lead, the contact and the over-current wire, and heat generated by the ground wire current melts ice. The flexible ground wire ice melting wiring apparatus is reasonable in structure design and is small. A construction worker can conveniently carry the flexible ground wire ice melting wiring apparatus to climb up to a tower, and install and dismount the flexible ground wire ice melting wiring apparatus, ice on the ground wire of an overhead transmission line can be effectively melted, and tripping can not easily occur.

Description

technical field [0001] The invention relates to the technical field of ice-melting devices for overhead power transmission lines, in particular to a flexible ground line ice-melting wiring device. Background technique [0002] In the overhead transmission lines, heavy icing tends to occur in winter in some alpine mountainous areas or extremely harsh weather conditions in my country. Uneven icing tends to produce unbalanced tension, leading to serious accidents such as broken strands and broken wires, loosening and falling off of towers, damage to tower materials and even collapse of towers. In addition, because the overhead ground wire on the tower is not like the transmission wire, which can resist partial freezing through the heat generated by the load current, the thickness of the ground wire's ice coating is generally far greater than that of the transmission wire. [0003] At present, the existing domestic ground wire melting automatic wiring device can better solve th...
