Abstract
The paper analyzed problems of voltage level, heat dissipation, EMC and conversion efficiency of inverter existed in using process of explosion-proof frequency converter in coal mine underground, and introduced methods of solving these problems in details, namely using technologies of flameproof and intrinsic safety and heat dissipation with heat pipes to solve problems of explosion-proof and heat dissipation of frequency converter, which can make explosion-proof frequency converter has characteristics of high performance, strong functions and low noise; using technical means of changing circuit topology and improving control strategy of frequency converter to solve problems of EMC and energy consumption of frequency converter, which can make explosion-proof frequency converter meet with requirements of modernization of coal mine production.关键词
