近日,河南省电力勘测设计院发明的“500千伏大跨距支持式管母线”获得国家发明专利。这是该院划转移交到中国电建集团以来的一项重要成果。该专利为每个管母支撑点采用绞接,取消托架,减小支柱绝缘子在各种工况下弯矩和扭矩,解决了500千伏支持式管母挠度和微风振动超标等方面的问题。该新型500千伏支持式管母的应用可缩短工期、节约投资,且具有布置清晰、施工检修方便、运行可靠
Recently, Henan Electric Power Survey and Design Institute invented the “500 kV large span support tube bus” access to national invention patents. This is an important achievement since the transfer of the hospital's plan to China Power Construction Group. The patented hinge for each tube support points, cancel the bracket, to reduce the pillar insulators in a variety of conditions, bending moment and torque to solve the 500 kV support tube deflection and breeze vibration and other aspects of the problem . The new 500 kV tube-type support application can shorten the construction period and save investment, and has a clear layout, construction and maintenance easy, reliable operation
