Description

technical field [0001] The invention belongs to the arc protection fabric technology, in particular to a high-efficiency arc protection fabric and a preparation method. Background technique [0002] Arc is the instantaneous discharge of high-voltage electrical appliances in the case of short circuit or dielectric breakdown, which will generate huge heat and thermal shock. The energy generated by the arc is as high as 8-60MW. The arc occurs very fast, the duration is short, and the total energy generated is very large, and the core temperature can reach 10,000°C. The accumulation of high energy in a short period of time can cause fatal injury to workers near the arc interface. The arc accident is mainly caused by the arc, which causes damage to the power equipment such as parts of the switchgear, cables, transformers, etc., and at this time, for the maintenance staff, the huge energy released by the arc combustion will cause personal injury to them. serious threat or injur...
