摘　　要：为提升油罐区电缆槽盒耐火性能测试的准确性和效率,提出一种以绝缘电阻作为判定指标的电缆槽盒耐火性能快速测试方法,并以试验的方式验证该方法的有效性和电缆槽盒的耐火性能。结果表明:测量电缆绝缘电阻值可以准确反映电缆槽盒在火灾时的失效过程,以107Ω作为电缆绝缘电阻失效判定指标可以准确反映电缆槽盒的耐火极限。To enhance the accuracy and efficiency of fire resistance testing for cable tray box in oil tank farms,a rapid testing method using insulation resistance as the determining criterion is proposed.Validation experiments were conducted to investigate the efficacy of this testing method and assess the fire resistance of cable tray box.The findings indicate that testing cable trough fire resistance by measuring cable insulation resistance effectively captures the failure process under fire conditions.Adopting 107Ωas the threshold for insulation resistance failure accurately represents the fire endurance limit of cable tray box.
