热料埋刮板输送机电气保护应用浅析

Electrical protection application analysis of hot material en masse conveyor

介绍了硫酸生产热料埋刮板输送机电气保护系统工作原理及存在问题,通过缩小测速圆孔直径、增加测速圆孔数量及重新设置电机多功能保护器电气保护参数等措施,避免了电气保护系统没有动作或动作滞后现象,从而保证了热料埋刮板输送机的正常运行。

The principle and problems of electrical protection systems of hot materials en masse conveyor in sulphuric acid plant are described. No-action or action hysteresis of electrical protection systems was avoided by reducing diameter and increasing number of speed-measuring holes, and resetting electrical protection parameters of multi-function electrical motor protector, to ensure normal running of the hot material en masse conveyor.
