矿井提升机消弧性能的改进设计

Improving Design to the Performance of Arc Extinction in Shaft Hoist

针对矿井提升机控制系统中的消弧性能改进问题提出一种新的方法。 采用电子消弧电路取代传统的消弧继电器,提高了消弧延时的精确性和 可靠性。

The paper suggests a new kind of method aiming to the improvement to the performance of arc extinction in control system of shaft hoist. It also indicates that the accuracy and reliability of time retardation for arc extinction can be increased by replacing traditional extinction relay with electron extinction circuit.
