Ishlab chiqarish tavsifi
DC leakage current sensor is a measuring module that converts the measured direct current into the proportional direct current or voltage signal according to the fluxgate theory and the input side is highly insulated from the output side. Typical outputs include 4-20mA, DC0-5V and DC0-10V signals. These standard signals can be acquired by various devices such as PLC, RTU and DAS cards and used for different current monitoring applications. leakage current transformerS surround the outlet plus and – of DC circuit.
O'chirish tarmoqlaridagi sensorlarning chiqish signallarini aniqlaydi. O'chirish tarmoqlaridagi izolyatsiya normal bo'lsa, sensordan o'tadigan oqim teskari yo'nalishda teng bo'lishi kerak. Chiqish signali nolga teng. Agar kontaktlarning zanglashiga olib keladigan filiali topraklanmış bo'lsa, differentsial oqim qochqin oqimi transformatoridan o'tadi va sensorning chiqishi nolga teng emas. Shuning uchun, kontaktlarning zanglashiga olib keladigan tarmoqlaridan chiqish signallarini aniqlash orqali doimiy oqim tizimidagi tuproqli filialni aniqlash mumkin. Nazariya chiziqni aniq aniqlashni kafolatlaydi va taqsimlangan sig'imning ta'sirini oldini oladi.
