数字微波网作为广播电视传输网的主要传输网络之一,特别是高山发射台站最重要的传输手段,具有抵御自然灾害能力强、防范恶意破坏能力强、受地理环境限制小、建设和维护成本相对较低等优点。在省级覆盖区域范围内,数字微波站可分为中心站(首站)、枢纽站(总站)、终端站等等。根据《广播电视安全播出管理规定》,对干线微波传输电路微波首站和微波总站的供配电系统稳定性,提出了比较高的要求。据相关资料统计,近年来全国广播电视安全播出事故中,因供配电问题导致的原因占据了很大比例,因此对于微波传输站的运行维护人员,如何提高微波传输站供配电系统的稳定性,防范和及时应对各种突发性停电事件,在日常工作中是一个重要任务。笔者在实际工作中积累了一些供配电系统维护及改造方面的经验,仅供同行参考借鉴。
Digital microwave network as one of the main transmission network of radio and television transmission network, especially the alpine launch station the most important means of transmission, with the ability to resist natural disasters, malicious vandalism, limited by the geographical environment, construction and maintenance costs Relatively low and so on. Within the provincial coverage area, digital microwave stations can be divided into central station (first station), hub (terminal), terminal station and so on. According to “Radio and Television Broadcasting Management Regulations”, the main microwave transmission line microwave terminal and the microwave terminal for the stability of the power supply and distribution system, put forward relatively high requirements. According to relevant statistics, in recent years, the national broadcast and television broadcast security accidents, due to power distribution problems account for a large proportion of reasons, so the operation and maintenance of microwave transmission stations, how to improve the microwave transmission station for the power distribution system Stability, prevention and timely response to a variety of unexpected blackouts, in daily work is an important task. The author in the actual work has accumulated some experience for the maintenance and transformation of power distribution systems, for reference only by peers.
