摘　　要：中国城镇化推动了环网柜的发展,对环网柜提出了高可靠、小型化、环保及智能化的要求。近年来为适应这些要求而研发和生产了多种类型的环网柜,笔者对目前市场上,中压配电柜的几种主要绝缘方式进行了论述与比较,进而提出了一种抽出式紧凑型空气绝缘环网柜,并对该种柜型的结构特点、可靠性、经济性进行了分析,为中压开关柜的发展提供了借鉴作用。China＇s urbanization promotes the development of RMU, and put forward the requirements of high reliability, miniaturization, environmental protection and intelligence for RMU. In recent years, in order to meet these requirements, various types of RMU have been developed and produced, several kinds of main insulation medium voltage power distribution cabinets in the current market are discussed and compared. Meanwhile, a with- drawable compact air-insulated RMU is put forward, and the structure characteristics, reliability and economy of this kind of cabinet are analyzed. It provides a reference for the development of medium voltage switchgear.
