一起中继泵热力配电盘烧毁原因分析和处理

Cause Analysis and Treatment of Burnout of a Relay Pump Thermal Distribution Board

某电厂配电控制柜投运时间长,在一次设备运行中发生电气短路,设备严重烧毁。基于该设备发生的故障及存在问题,从配电盘设计存在的缺陷、设备周围工作环境条件及设备日常管理等入手,查找存在问题,最终确定了电气设备短路故障原因。从技术、环境、管理方面制定解决方案,并结合生产现场受控设备的实际使用情况,实现对原有热力配电盘升级改进,进一步提高了配电设备安全可靠性、稳定性。

The distribution control cabinet of a power plant has been operation for a long time,it been seriously burnt by the short circuit fault during the operation of the equipment.According to the faults and existing problems of the equipment,the possible problems are studied first from the defects in the design of the distribution board,and the working environment conditions around the equipment then the daily management of the equipment,the cause of the short circuit fault of the electrical equipment is finally determined.Take into account the aspects of technology,environment and management,and combined the site operation condition of controlled equipment,the upgrading and improvement of the original thermal power distribution board is realized,and the safety,reliabiliy and stability of the distribution equipment are further improved.
