电缆隧道内电缆接头温度监测及防火预警的研究

Study on the temperature monitoring and fire prevention of the cable joints in the cable tunnel

实际传输电能时,如果电缆线比较长,每隔100m就需要设置1个接头,电缆接头数量过多会容易受到影响,内外部故障,甚至因为电缆接头温度过高导致电缆火灾。其实电缆接头故障是一个渐进的过程,为了全面规避隐患事故,需要对电缆隧道内电缆接头温度进行监测,设计电缆接头温度监测与防火预警系统,实时了解温度变化情况,一旦发生故障可以及时解决。文章以提高电缆隧道工程安全性为前提,针对电缆接头温度监测与防火预警系统中展开了研究,首先介绍了电缆接头温度监测模式以及监测方式,其次阐述了电缆接头温度监测及防火预警系统设计,从而正确认识了该系统设计对于解决电缆接头故障的重要性,希望能够为今后电缆隧道相关工作的研究提供可参考意见。

When the actual transmission of electricity,if the cable is relatively long,every 100 m will need to set up1 joints,too many cable connectors will be easily affected,internal and external faults,and even because the cable joint temperature is too high,leading to the cable fire. In fact,cable joint fault is a gradual process,in order to avoid accidents,need to monitor the temperature of cable joint cable tunnel,the design of cable joint temperature monitoring and fire alarm system,real-time understanding of the change of temperature,and can solve the faults. In order to improve the safety of cable tunnel project is the premise for cable joint temperature monitoring and fire alarm system are researched,first introduced the temperature monitoring mode and monitoring mode of cable joint,secondly cable joint temperature monitoring and fire alarm system design,so as to have a correct understanding of the importance of system design to solve the cable joint fault the study hope to the future of cable tunnel related work can provide reference.
