The subject of graduation qualification work: "Reconstruction of substation 150/10 kV of PJSC "IDGC North-West"taking into account the experience of switching devices operation." Reconstruction of the substation of the Murmansk branch is considered in this work. Objectives of the study: 1. Analysis of the current state of equipment of the 150/10 kV substation. 2. Reconstruction of electrical part of substation: determination of reconstruction volume, calculation of short-circuit currents, selection of switchgear equipment. 3. Analysis of operation, comparative assessment and justification of selection of high-voltage switches. Short circuit currents were calculated for selection and check of equipment, the circuit after dismantling of the withdrawn power transformer and reconstruction of the 10 kV RP was selected. Power transformers are selected based on calculations of power flows. Selection of switches on the high voltage side is justified. The operation of high-voltage switches of the substation before reconstruction was analyzed. The history of development of high-voltage switches is considered. The main characteristics of high voltage switches were compared. Need of accounting of a real switching resource of the switch, by the analysis of damages, the abnormal modes, violations in work of means of automatic equipment of substation with RU of 150 kV during the period is considered from 01.01.2017 till 01.12.2019.
