漏電流傳感器用于直流m級微小電流的隔離、穿孔式測量,可按用戶需求定制不同可定制。漏電流傳感器環(huán)繞安裝在直流回路的正負出線上,當(dāng)裝置運行時實時檢測各支路傳感器輸出的信號,當(dāng)支路絕續(xù)情況正常時,流過傳感器的電流大小相等,方向相反,其輸出信號為零:當(dāng)支路有接地時,漏電流傳感器有差流流過,傳感器的輸出不為零,因此通過檢測各支路傳悠器的輸出信號,就可以判斷直流系統(tǒng)接地支路。該原理選線精度高,不受線路分布電容的影響。直流漏電流變送器是一種利用磁通門原理(Flux gate)將被測直流電流轉(zhuǎn)換成與該電流成比例輸出的直流電流或電壓信號的測量模塊,原副邊之間高度絕緣。具有高精確度、高線性度、高集成度、體積小結(jié)構(gòu)簡單、長期工作穩(wěn)定且適應(yīng)各種工作環(huán)境的特點,普遍地應(yīng)用在新能源、石油、煤礦、化工、鐵路、通信、樓字自控等行業(yè)的電氣設(shè)備的系統(tǒng)控制及檢測。</p><p

ASIC中實現(xiàn)。與磁通門結(jié)構(gòu)的傳感器相比，新型的漏電流霍爾閉環(huán)傳感器減小了封裝尺寸并簡化生產(chǎn)制作工藝。此外，減少的電子和機械部件可提高長期工作的可靠性。盡管架構(gòu)簡單，但設(shè)計本身仍具有挑戰(zhàn)性：為了減小傳感器封裝，原邊導(dǎo)線要嵌入到傳感器中。導(dǎo)線會產(chǎn)生大量的熱，電流密度和原副邊的隔離都會受到限制。磁路需要準確以應(yīng)對檢測較小的剩余電流，同時抵抗較強的共模電流。優(yōu)化原邊導(dǎo)體與霍爾元件之間的耦合是必不可少的。該架構(gòu)對外部磁場非常敏感：整體的電磁設(shè)計必須防止外部電磁場的干擾。漏電流傳感器是一種利用磁通門原理將被測直流電流轉(zhuǎn)換成與該電流成比例輸出的直流。</p><div
