吊运熔融金属的冶金起重机的电气检验探讨分析

Analysis of electrical inspection of metallurgical crane for lifting and transporting molten metal

冶金起重机在熔融金属的吊运当中起着至关重要的作用,相较于普通企业中所使用的起重机,冶金起重机的使用频率更高,机械的工作环境也更加恶劣,对自动化也有着更高的要求。本文从电动机、超速开关和正反向接触器三个方面对其的电气检验进行了阐述。

Metallurgical Crane in molten metal lifting which plays a vital role,compared to ordinary enterprises used in cranes, metallurgical crane used in a higher frequency,mechanical work environment is even worse,for automation also has a higher requirements.In this paper,from three aspects of the motor,the speed switch and the positive reverse contactor,the electrical inspection is described.
