摘　　要：在沿海地区,由于配电变压器在整个配电网损耗的比重较大,提出了高过载调容变压器的应用情况。介绍了高过载调容变压器结构组成、调容技术原理及控制方式。高过载调容变压器根据电力系统的负载情况能够自动切换容量,避免了电力线路由于负载过高而造成电力灾难。同时设计了高过载调容变压器的应用系统。用户可以通过远程无线通讯的方式实时监控、接收、处理高过载调容变压器的现场数据。在相同时间段内,通过与普通配电变压器进行比较,使用高过载调容变压器后,克服了沿海地区负荷集中、时段性强、平均负荷率高的问题,能够获取明显的经济效益。In the coastal areas,due to the large proportion of distribution transformers in the distribution network,the application of high overload capacity transformers is proposed.This paper introduces the structure of the high overload capacity transformer,the principle of the capacity adjustment and the control method,and introduces that the high overload capacity transformer can automati cally switch the capacity according to the load of the power system,avoiding the power disaster caused by the high load of the power line.At the same time,the application system of high overload capacity transformer is designed.Users can monitor,receive,and pro cess the field data of high-overload transformers in real time through remote wireless communication.In the same period of time,after comparing with ordinary distribution transformers,the use of high-overload transformers overcomes the problems of concentrated load,strong time and high average load rate in coastal areas,and can obtain obvious economic benefits.
