Green and self-starting fire extinguishing for electric energy metering boxes

Energy security is an overall and strategic issue related to the country's economic and social development. With the increasing integration of electric vehicles, energy storage and other equipment into the distribution network, more and more attentions have been paid to metering box fire.To improve the intrinsic safety of the power grid, reduce greenhouse gases caused by flame combustion and ensure the personal and property safety of the power grid and customers, preventing the spread of metering box fires and timely restoration of power supply are important.In this paper, a flexible and temperature sensing self-starting fire extinguishing device for metering boxes is proposed, which can achieve a time of ≤ 10s from the occurrence of an open flame to extinguishing. Compared to traditional products, the fire extinguishing efficiency has been improved by 60% or more. The time to restore power has been reduced by 80%. The product is environmentally friendly and does not generate secondary pollution during daily operation and maintenance. It can also greatly reduce greenhouse gases caused by flame combustion, contributing to the achievement of carbon peaking and carbon neutrality goals.
