Protection system for dry type three-phase digital transformer with smartphone

摘要

A protection system of a dry-type three-phase digital transformer interlocked with a smartphone 700 is introduced. To this end, the present invention provides a protection system for a dry 3-phase lottery digital transformer 100 interlocked with a smartphone 700, comprising: a plurality of dry 3-phase lottery digital transformers 100; R, S, T, N lines input to each of the dry-type three-phase lottery digital transformer 100; a short-circuit detection sensor 300 formed on each of the R, S, T, and N lines to detect whether the respective R, S, T, and N lines are short-circuited; a temperature sensor 200 for measuring the temperature of each of the dry three-phase lottery digital transformers 100; an output voltage sensor 500 for measuring a voltage value output from each of the dry three-phase lottery digital transformers 100; PLC servo drive 400 connected to each of the dry type three-phase lottery digital transformer 100; a voltage abnormality detection sensor 600 for determining whether there is a voltage abnormality by measuring the voltage value output from the PLC servo drive 400; When a separate app is installed and the app is executed, the signal value sensed in real time by the short circuit detection sensor 300, the temperature detection sensor 200, the output voltage detection sensor 500 and the voltage abnormality detection sensor 600 is It is characterized in that the presence or absence of each abnormality is displayed on the display unit of the smartphone (700).
