Analysis on Fire Risk of Aluminium Conductors under Electrical Faults in Low Voltage Circuit

摘要

In this article, the fire risk of aluminium conductors which were in poor contact and short circuit of low-voltage were validated. Meanwhile, the temperature of aluminium droplets which were falling during experiments was measured. As a result, it showed that the common combustible, such as hay, cotton, paper and polyurethane foam can be ignited under bad contact and short conditions, which aimed to provide the important references for exploring the fire scene and investigating the reasons of electrical fires once the relevant evidences existed.
