提高煤炭工业生产效率的关键在于通过采用完善的采掘机械,加大采掘机械的电力驱动装置的功率,把高产采区电气设备的供电电压提高到1140伏,采用自动调节的电力驱动装置、远距离控制和自动控制,保证安全和可靠性能等途径达到煤矿生产集中化和强化的目的。所有这一切均要求电源装置、起动控制装置和保护装置,以及电动机和电力驱动系统等具有很高的防爆性和可靠性。
The key to improve the production efficiency of the coal industry is to increase the power supply of the electric drive of the mining machinery by adopting a perfect mining machinery and raise the supply voltage of the electric equipment of the high-production mining area to 1140 volts. The electric drive device with automatic adjustment is adopted and the distance Control and automatic control, ensure safety and reliability, and other means to achieve centralized and enhanced production of coal mine purposes. All of this requires a high degree of explosion-proofness and reliability of power supply units, start-up controls and protectors, as well as motors and electric drive systems.
