SYNTHESIS OF THE STRUCTURE OF THE DEVICE FOR ASSESSING THE WORKING RESOURCE OF THE REGULATORY DEVICE UNDER LOAD

Abstract. The work focuses on on-load regulation devices (on-load tap-changer) of power transformers, on the reliability of which the reliability of electricity transmission depends. Emphasis is placed on the need to control the consumption of the mechanical resource, which depends on the number of switches of the tap-changer device contacts, and the switching resource, which depends on the value of the commutated current at the moment of branch switching. Using the mathematical apparatus of sequences, the structure of the device was synthesized for evaluating the consumption of mechanical and switching resources of the on-load tap-changer during its operation.
