Description

一种用于架设配电线路的混凝土电杆A concrete pole for erecting distribution lines

技术领域 technical field

本实用新型涉及电力线路架空设施,具体涉及一种用于架设配电线路的混凝土电杆。  The utility model relates to an overhead facility of a power line, in particular to a concrete pole used for erecting a power distribution line. the

背景技术 Background technique

近年来,随着我国电力工业的迅猛发展,在架设配电线路的混凝土电杆时,有防雷设施及杆上设备的必须要有可靠的接地。现有的混凝土电杆一般都采用外露式的接地管加接地引下线的结构,即采用一根规格为8m×25mm2的铜绞线作为接地引下线,并沿着电杆的外表面从杆上设备引入地下。这种结构的电杆不光影响城市街景美观,更重要的是在偏僻地区,电杆上的接地引下线铜绞线经常被偷窃,使杆上设备因接地不良而造成雷击和供电事故,影响了电网的安全可靠运行。因此,接地引下线的接地都需要定期地进行巡查。另外,暴露的接地引下线由于受大气腐蚀,也需要定期维护,因此浪费了大量的人力物力资源。  In recent years, with the rapid development of my country's electric power industry, when erecting concrete poles for distribution lines, lightning protection facilities and pole-mounted equipment must have reliable grounding. Existing concrete poles generally adopt the structure of exposed grounding pipe plus grounding down-conductor, that is, a copper stranded wire with a specification of 8m× 25mm2 is used as the grounding down-conductor, and is connected along the outer surface of the pole. The device is introduced into the ground from the pole. Electric poles of this structure not only affect the beauty of urban streetscapes, but more importantly, in remote areas, the copper stranded wires of grounding downconductors on electric poles are often stolen, causing lightning strikes and power supply accidents caused by poor grounding of the equipment on the poles, affecting safe and reliable operation of the power grid. Therefore, the grounding of the grounding downconductor needs to be inspected regularly. In addition, the exposed grounding down conductor also needs regular maintenance due to atmospheric corrosion, thus wasting a lot of manpower and material resources.
