一、概述杆塔是电气化铁道牵引变电所内屋外配电装置的组成部份之一。已往电化区段采用的AП型杆塔如图1所示。这种构架类型經过实际运行考驗已能满足电气化铁道的运营需要,但在制作、安装、投資和用料方面还存在着一些缺点。为此,按照建設社会主义的总路綫和各项方針政策的精神来改造牵引变电所屋外配电装置的杆塔設計,是一項生产斗争的任务。經过調查研究和分析比较后,确定按照下列几个原
I. Overview The tower is one of the components of the electrical distribution equipment inside the electrified railway traction substation. In the past, the AП tower used in the electrification section is shown in FIG. 1. This type of structure after the actual operation of the test has been able to meet the operational needs of the electrified railway, but in the production, installation, investment and materials there are still some shortcomings. To this end, it is a task of the production struggle to transform the tower design of the power distribution unit outside the traction substation according to the general line of building socialism and various principles and policies. After investigation and analysis and comparison, determine the following in accordance with the original
