Mine explosion-proof and intrinsically safe high-voltage permanent magnet synchronous frequency conversion speed regulation integrated machine

Abstract

The application belongs to the technical field of mining mobile substation and mining frequency conversion integrated machine, especially to a mining explosion-proof and intrinsically safe high-voltage permanent magnet synchronous frequency conversion integrated machine, comprising a frequency conversion integrated machine body, a water cooling pipe arranged inside the frequency conversion integrated machine body, water inlets and outlets respectively installed on the two sides of the shell of the frequency conversion integrated machine body, the two ends of the water cooling pipe connected with the water inlets and outlets, a water tank and a cooling pipe fixedly connected on the top of the shell, a water pump installed in the water tank, the water outlet end of the water pump connected with the cooling pipe, the other end of the cooling pipe connected with the water inlet, the water outlet connected with the water tank through a return pipe, and an air cooling assembly arranged at the cooling pipe. In the application, the water cooling pipe directly cools the inside of the frequency conversion integrated machine body, the cooling pipe and the cooling fan cooperate to inhibit the temperature rise of the cooling liquid, the double cooling mechanism significantly improves the heat dissipation effect, adapts to the high-temperature working environment, and meets the explosion-proof requirements.
