环网柜电缆接头温度在线监测方案设计

Online Monitoring Scheme Design of RMU Cable Connector Temperature

环网柜电缆接头温度是衡量环网柜及电网安全运行的重要指标,环网柜电缆接头温度过高容易导致爆炸事故,会降低供电可靠性造成巨大的经济损失。所以,对环网柜电缆接头温度的监测显得尤为重要。为了满足智能配电网对环网柜电缆接头温度的监测要求,此文从电缆接头所处的环境温度、电缆接头本身及环境温度的上升速率等方面,设计了一种电缆接头温度在线监测方案;主要包括监测方法及判据的提出、监测系统的结构设计以及监测主站系统的设计。

RMU cable connector temperature is an important indicator to measure RMU and power system safety operation.The high temperature of RMU cable connector easily leads to explosion,which will reduce the reliability of power supply and cause huge economic losses.Therefore ,the monitoring on RMU cable connector temperature is particularly important.In order to meet the monitoring requirements of smart distribution network for RMU cable connector temperature,in terms of the ambient temperature of cable connector,the cable connector itself,the rising rate of ambient temperature and other perspectives ,this paper designs an online monitoring scheme of RMU cable connector temperature,which includes the proposal of monitoring methods and criteria, structure design of the monitoring system and design of monitoring master station system.
