SSN-AVC,PT,Converter(Wall,Mount),,傳遞觸發(fā)信號(hào),一般采用光纖傳輸,能有效地避免各種電磁干擾。通過光纖傳遞信號(hào),也有兩種方式:一種多光纖方式,一種單光纖方式。多光纖方式即每塊觸發(fā)板有一路光纖;單光纖方式即每一相只有一路光纖,信號(hào)傳遞到一塊主觸發(fā)板,再由主觸發(fā)板傳遞到同一相的其他觸發(fā)板。由于各路光纖光電傳輸過程中損耗不盡一致,因此從觸發(fā)一致性上看,單光纖的方式比多光纖可靠。高壓軟啟動(dòng)器對(duì)信號(hào)的檢測(cè)比低壓軟啟動(dòng)器要求更高。高壓軟起動(dòng)器所在的環(huán)境存在著大量的電磁干擾,并且高壓軟啟動(dòng)器所用的真空接觸器和真空斷路器在其分?jǐn)嗪烷]合過程中會(huì)產(chǎn)生大量的電磁干擾。所以對(duì)檢測(cè)到的信號(hào)不僅要進(jìn)行硬件濾波,也要進(jìn)行軟件濾波,去掉干擾信號(hào)。軟啟動(dòng)器在完成啟動(dòng)過程后。
