摘要
对RTU机柜烧毁现场进行了勘查和调查,从多角度进行原因分析。综合判定表明,变压器缺陷、安全栅故障是产生火源的直接原因;机柜布线不合理、柜内通风散热不畅和阀室供配电设计不合理是引发火灾的间接原因。总结并提出了远传截断阀室RTU机柜的技术改造建议。这些建议对将来同类机柜的设计、选型、集成具有重要参考意义。
The Survey and investigation for the site of burned RTU cabinet are conducted,the causes are analyzed from various angles,the comprehensive judgment is:transformer defects and faults ofsafety barriers are the direct cause of producing fire source; while unreasonable wiring,poor ventilation and heat dissipation inside cabinet,and improper power supply of the valve chamber are the indirect causes of posing a fire.The proposal of the technical transformation for blocking the valve chamber the RTU cabinet by remote transmission method is summarized.The suggestion possesses important significance to design,select and integrate similar cabinets in future.
