电缆燃烧典型火源模拟方法综述

A review of typical fire source simulation methods for cable combustion

针对电缆火灾问题,综述了国内外电缆火灾模拟试验及电缆燃烧测试中使用的火源模拟方法,并对比探讨了多种火源模拟方法的点火时间、火源温度、火源面积、火源功率、可扩展性、可移动性以及可持续使用性等方面的差异:燃气喷灯法和辐射加热法(锥形量热计)所需点火时间短;电加热法火源温度高,操作简便易移动;燃油点火法的点火面积大,可扩展性强;电弧引燃法的温度最高、可控性强。以期为电缆火灾模拟及防火提供参考。

Regarding the issue of cable fires,this paper comprehensively reviews the fire source simulation methods used in cable fire simulation tests and cable combustion tests.These fire source simulation methods are discussed from aspects of the ignition time,fire source temperature,fire source area,fire power,scalability,removability and sustainability.The gas burner method and the radiant heating method(cone calorimeter)have a short ignition time;The electric heating method has high fire source temperature,and it is easy to operate and move;The fuel ignition method has a large ignition area and strong scalability;The arc ignition method has the highest temperature and strong controllability.The paper is expected to provide an important reference for cable fire simulation and fire protection.
