Abstract

conversor de entrada de corrente. é descrito um conversor de entrada de corrente (13) que converte uma corrente de entrada, recebida por uma mesa terminal (11), em um sinal analógico predeterminado, por isolamento elétrico da corrente de entrada pelo transformador (14), e converte o sinal analógico, obtido pelo transformador (14) em um sinal digital, por um circuito de conversão de analógico em digital (18). a mesa terminal (11) do conversor de entrada de corrente e uma extremidade de uma bobina do lado primário do transformador (14) são conectadas por uma primeira placa metálica e uma segunda placa metálica, que têm formas sólidas. a primeira placa metálica tendo a forma sólida tem uma extremidade presa na mesa terminal (14), e a outra extremidade presa na mesa terminal (14), e a outra extremidade presa na extremidade da bobina do lado primário do transformador (14). a segunda placa metálica tendo a forma sólida tem uma extremidade presa na mesa terminal (11), e a outra extremidade presa na outra extremidade da bobina do lado primário do transformador (14), e conecta a mesa terminal (11) e a outra extremidade da bobina do lado primário do transformador (14).
