摘　　要：采用锥形量热计,测量不同外加热辐射通量下绝缘纸板的着火时间、质量损失和热辐射通量,并研究不同外加热辐射通量可能带给变压器的火灾影响。结果表明,外加热辐射通量增加到一定程度时,绝缘纸板质量损失及热释放速率增加较快,其与外加热辐射通量并非线性关系。A cone calorimeter is used to measure the ignition time, mass loss and heat radiation flux of insulating cardboard under different external heating radiation fluxes, and studies are conducted on the fire hazards to the transformer caused by external heating radiation flux environments. The study shows that the mass loss and heat radiation flux of insulating cardboard increases a lot when the external heating radiation flux grows up to a certain degree, and their relations with the external heating radiation fluxes present nonlinear.
