Description

technical field [0001] The invention relates to the technical field of cable fire protection, in particular to a cable fire protection device and a use method thereof. Background technique [0002] With the development of economy and society and the upgrading of power equipment, power cables are widely used for their advantages of saving ground space and low ground fault rate of cable lines. However, when power cables are used, insulation damage is more likely to occur due to materials or construction reasons, causing breakdown and fire at the cable head, and there have also been cases where the cable caught fire due to fire in the surrounding environment of the cable, resulting in power interruption and serious economic losses; therefore , how to carry out fire resistance to the cable is a very important topic in the power system. [0003] Application date 2014.09.01, application number 201410456144.8 patent discloses a cable automatic fire extinguishing device, including ...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned device only uses a fire extinguisher to extinguish the fire, and the fire extinguishing effect is single, and the fire extinguishing effect is limited. If the surrounding environment of the cable catches fire and the fire is relatively large, a single fire extinguisher is obviously not enough to extinguish the fire.
