一、引言随着我国广播电视事业的高速发展,众多新颖的广播电视大楼拔地而起,根据高层建筑电力传输和广电系统的用电负荷特点性质,大楼一般在低区设有一个中心变电所,而在大楼的中区和高区分别设有性质和作用不同的变电所,如播出系统工艺用电变电所和大楼高区变电所,这样即避免了电力传输上的损耗,也保证了广播电视播出系统工艺用电独立安全运行。同时,广播电视大楼低区还设有较大功率的应急自备发电机组
I. INTRODUCTION With the rapid development of radio and television industry in our country, many innovative radio and television buildings have been built up. According to the nature of the load characteristics of power transmission and broadcasting system in high-rise buildings, the building generally has a center substation In the middle and high areas of the building, there are substations of different nature and functions, such as the broadcasting of system and technology substation and high-rise substation of building, thus avoiding the loss of power transmission , But also ensure that radio and television broadcasting system technology independent safe operation of electricity. At the same time, low-rise radio and television building also has a larger power emergency self-generating units
