atse的分类及其特点（Classification and characteristics of ATSE）

atse的分类及其特点（Classification and characteristics of ATSE） Abstract: This paper introduces the classification and characteristics of ATSE, and its application in practical engineering design are analyzed. PC and CB have their own advantages and disadvantages, the designer should consider to choose the design. Keywords: ATSE, PC, CB, switching time, use category, number of poles 1 Introduction In the design of power distribution system for civil buildings, in order to guarantee the reliability of the important load power supply, many norms have a clear requirement for the power supply, the national standard Specification for design of distribution system (GB50052-2009) code for electrical design of civil architecture and standard (JGJ16-2008) requirements: for a load, by double power supply when the power supply, a power failure, another power should not be damaged; the power supply system of two level load, advised by the two circuit power supply. According to the national standard architectural fire standards (GB50016-2006) and fire protection design of tall buildings (GB50045-95) (2005 Edition), the power supply of the building fire control room, fire pump, fire elevator and smoke exhaust fan, fire fighting equipment, should be set to automatically switch on the terminal of the distributing box device. Therefore, in order to ensure the continuity of the important load power supply, dual power automatic transfer switching equipment used in civil buildings expanding. With the rapid development of science and technology, civil building height increased, its function also increases, the building appeared in one or two load probability is more and more big. So the application of ATSE was also increased. However, the technical performance of ATSE requirements continue to increase, so the reasonable selection of ATSE will become more and more important, so the electrical design personnel should be familiar with and understand the composition and working principle, main char
