Description

一种电气火灾监控器An electrical fire monitor

技术领域technical field

本发明涉及监控设备技术领域，特别涉及一种电气火灾监控器。The invention relates to the technical field of monitoring equipment, in particular to an electrical fire monitor.

背景技术Background technique

随着居民生活水平的提高，用电设备大量增加，民用建筑用电量也逐年增加，由电气线路直接或间接造成的电气火灾也随之增加。据相关资料统计，如2002年鉴定的115起火灾中，其中电气火灾占95起，可见加强电气火灾的防范已经迫在眉睫。电气火灾的起火原因较多，包括短路、过热、漏电、雷击和电气故障等，火灾危害也较大。因此，各种原因引起的火灾都应得到有效控制。目前，短路、过热、雷击等保护措施日渐成熟，而由于正常泄露电流的普遍存在，漏电往往没有引起足够的重视，从而导致火灾发生。显而易见，采用漏电电流检测，给出火灾预警的报警系统十分必要，随着我国相关产品标准和设计规范的相继出台，促进了漏电火灾报警系统即电气火灾监控系统在工程中应用。现有的电气火灾监控系统对于漏电产生有火灾监控技术比较落后，可靠性低，并且只能通过监测线路的漏电进行报警和控制，对于可能产生电气火灾的其它故障原因不能进行全方位的监控。With the improvement of residents' living standards, a large number of electrical equipment has increased, and the electricity consumption of civil buildings has also increased year by year, and the electrical fires caused directly or indirectly by electrical lines have also increased. According to relevant statistics, among the 115 fires identified in 2002, 95 were electrical fires, which shows that it is imminent to strengthen the prevention of electrical fires. There are many causes of electrical fire, including short circuit, overheating, leakage, lightning strike and electrical failure, etc., and the fire hazard is also relatively large. Therefore, fires caused by various reasons should be effectively controlled. At present, protective measures such as short circuit, overheating, and lightning strikes are becoming more and more mature, but due to the prevalence of normal leakage current, leakage is often not paid enough attention, which leads to fires. Obviously, it is very necessary to use leakage current detection to give fire warning alarm system. With the successive introduction of relevant product standards and design specifications in our country, the application of leakage fire alarm system, that is, electrical fire monitoring system, in engineering has been promoted. The existing electrical fire monitoring system is relatively backward in fire monitoring technology for leakage, has low reliability, and can only monitor and control the leakage of the circuit, and cannot perform all-round monitoring for other faults that may cause electrical fires.
