埋地式变压器在城市配网供电工程中的应用

Buried Transformer and Its Application in Urban Distribution Engineering

随着城市的规划发展和城市电网改造的深入,安全、可靠与用电空间小的变、配电设备正得到越来越多的关注,地埋式变压器系列产品的出现适应了架空设备入地这一趋势,逐渐成为城网配线改造的一个新方向。它不仅节约了投资,而且能够美化城市环境。论述了埋地式变压器的基本技术及应用情况,比较了与常规配电设备的优缺点,提出今后在城市供电工程中埋地式变压器应做的改进。

With the development of the city planning and the reformation of the urban network, People have pay attention to the safety, reliable and compact distribution equipment. The buried transformer is suitable to meet the requirement of removing the overhead network in the city center, and is gradually becoming a new direction for the reformation of urban distribution system. Buried transformers are used not only for reducing the investment, but also for beautifying the urban environment. The fundamental technology of buried transformer and its application are introduced in this paper. Comparison is made between the buried transformer and the traditional distribution equipment. And some improvements in the application of buried transformers are suggested that could be referenced in the urban power supply engineering.
