Problems solved by technology

[0003] The current high-voltage wire passes through the iron tower in the center of the iron tower, and its structure is all composed of angle steel. The disadvantage is that one phase of the high-voltage wire directly passes through the iron tower to form the center of the ring iron, so a magnetic field is generated in the iron tower. The change of the magnetic field causes the iron tower to generate Eddy currents generate heat to cause power consumption, cause voltage drop, and shorten power transmission distance

Embodiment Construction

[0006] 1. Use stainless steel to make a connection plate with the same length, width and thickness and the same size as the connection part of the ring iron frame with the hole and the iron tower frame. It is used to connect the left and right joints of the iron tower, and replace part of the angle iron passing through the connection plate with stainless steel corner material. Or cut off a section and fix it with screws.

[0007] 2. A part of the angle iron constituting the closed circular iron frame in the iron tower frame can be replaced by stainless steel angle material, and its design size remains unchanged.

[0008] 3. For the V-shaped support tower, part of the triangular steel of the legs can be replaced with stainless steel.

[0009] 4. The iron tower of the tube structure forms a closed circular steel tube to separate the interface with stainless steel or insulating sheet material, and lock it with stainless steel screws.

Abstract

The invention relates to the field of high-voltage alternating current power transmission, in particular to a power saving method for an iron tower. A high-voltage wire penetrates through the center of an iron tower frame of the iron tower. In order to solve the technical problem, the technical scheme is that: a closed iron tower frame through which the high-voltage wire penetrates is connected through non-magnetically conductive metal or an insulating material, or a part of angle iron of the iron tower frame is replaced by a non-magnetically conductive material, and a closed magnetic field is cut off, so that a power saving aim is fulfilled. The method has the beneficial effects that the closed magnetic field is cut off, eddy current loss is reduced, a power transmission distance is prolonged, and the voltage drop of a power grid is reduced.

Description

[0001] Field [0002] The invention relates to the field of high-voltage alternating current transmission, in particular to a power-saving method for high-voltage wires passing through the central iron tower of an iron tower. technical background [0003] The current high-voltage wire passes through the iron tower in the center of the iron tower, and its structure is all composed of angle steel. The disadvantage is that one phase of the high-voltage wire directly passes through the iron tower to form the center of the ring iron, so a magnetic field is generated in the iron tower. The change of the magnetic field makes the iron tower generate Eddy currents generate heat to consume electricity, cause voltage drops, and shorten power transmission distances. Contents of the invention [0004] In order to solve the shortcomings of the above-mentioned iron tower, the present invention provides a power-saving method in which the high-voltage power transmission wire passes through t...
