单管式柱上变压器在海南滨海城市中的应用
|
摘要
随着城市电力负荷的快速增长及供电范围的不断扩大,为了满足用电量逐年大幅增长的要求,在现有配电电压等级情况下,新增配电变压器是解决电力供给侧问题的有效途径。由于滨海城市商品街区位置受限及商户协调困难等方面原因,给配电变压器的新增布点带来了巨大困难。为此,本文提出在滨海城市因地制宜地采用单管式柱上变压器,其最大的特点是变压器和综合配电箱安装于同根钢管上,极大地节省了城市占地面积,并通过与传统台架变压器、箱式变压器不同方面的对比及实例分析,证明该变压器安装形式在海南滨海城市的应用是切实可行的。
With the rapid growth of urban power load and the amplification of power supply range,adding distribution transformers is an effective way to solve the problem of power supply-side to meetthe requirements of increasing electricity consumption in the case of existing distribution voltage levels.Due to the limited location of commodity blocks and the difficulty of merchant coordination, it bringsgreat difficulties to add new distribution transformers. Therefore, single steel pipe transformer isproposed to apply to coastal city in this paper and its biggest feature is that the transformer anddistribution box are installed on the single steel pipe, which could greatly save the urban area. Throughthe comparison and case analysis of traditional bench transformer and cabinet transformer, it is provedthat the application of steel tube transformer in Hainan coastal city is feasible.
