ON THE EFFECTIVENESS OF AMORPHOUS ALLOYS IN MANDREL OF ARC-SUPPRESSING CONTACTOR SYSTEM

In the article the problem of arc control is considered in the process of exploitation of electric apparatuses on the example of work of contactors of direct-current. The ways of decision the problems are shown, based on the necessary technical requirements produced at planning to the constructions of the arc-suppressing systems. One of progressive decisions of this problem is the use of amorphous alloys in the mandrel of the arc-suppressing system, that will allow similarly to optimizing the construction of the system. The aim is determination of possibility of using of amorphous in the mandrel of the arc-suppressing system of contactor. We were studied magnetic characteristics, mechanical and chemical properties as well technological parameters of amorphous steels to achieve the goal. Experimental studies have been of work of contactor of direct-current with the use in the mandrel of amorphous steel in the arc-suppressing system. On results to the researches it was determined the possibility of application of amorphous steels in the mandrel of the arc-suppressing system and the further prospect of application of amorphous alloys in electric apparatuses.
