High-altitude ultra-high-voltage test terminal leading tower

Abstract

The invention discloses a high-altitude ultra-high-voltage test terminal leading tower. The high-altitude ultra-high-voltage test terminal leading tower comprises a tower body, an earth wire peak anda wire horizontal cross arm. The high-altitude ultra-high-voltage test terminal leading tower is characterized in that a plurality of wire hanging points are arranged on the lower planes of the left and right sides of the wire horizontal cross arm, and symmetrical alternating current wire hanging points are arranged in front and back of the middle position, at the height of the lower planes of thewire horizontal cross arm, of the tower body; a tower body longitudinal cross arm is arranged on the tower body in the direction of a power generator; side phase longitudinal cross arms are correspondingly arranged at the end parts of the left and right sides of the wire horizontal cross arm in the direction of the power generator; V-type insulator string hanging points are correspondingly arranged at the end parts of the tower body longitudinal cross arm and the side phase longitudinal cross arms; and inhaul cables are correspondingly connected among the earth wire peak and the side phase longitudinal cross arms on the left and right sides. According to the high-altitude ultra-high-voltage test terminal leading tower, multi-purpose of the tower is realized, test requirements of ultra-high-voltage direct current and alternating current engineering with the highest voltage level in the world are met, and engineering investment is greatly reduced.

Description

technical field [0001] The invention relates to a high-altitude ultra-high voltage test terminal drainage tower used for electrical tests of ultra-high voltage AC and DC transmission lines in high-altitude areas. Background technique [0002] With the rapid development of my country's economy, the demand for energy in all aspects of society is increasing, especially the main energy consumption points are concentrated in the central and eastern regions, while most of the energy sources such as coal, hydropower, and land wind energy are located in the western region. With the large-scale and intensive development and utilization of hydropower, the power development mode is changing from the local balanced development mode to the large grid network power supply mode; due to environmental pressure, high transportation costs, and land resources shortage in the eastern region, it is no longer suitable for large-scale construction of power grids. Coal power plants objectively determi...

Problems solved by technology

[0007] 4. Need to carry super heavy V string, the V string is located above the power generator

[0008] In order to solve the above technical problems, it is necessary to innovatively propose a high-altitude UHV test terminal drainage tower structure to solve the problem that the current high-altitude test drainage tower conductor cross-arm length has a maximum pole spacing of 18 meters, and the maximum load can only meet ±500kV DC Line load requirements (eg Figure 10 As shown), it cannot meet the test load and multiple pole spacing requirements of ±1300kV DC UHV transmission lines and 1000kV AC UHV transmission lines, as well as the electrical clearance requirements with the power generator
