IC693PW***2IC693PW***2屏蔽技术采用屏蔽技术可以有效防止电场或磁场的干扰。屏蔽又可分为静电屏蔽、电磁屏蔽和低频磁屏蔽等。4.3.1静电屏蔽用铜或铝等导电性良好的金属为材料,制作密闭的金属容器,并与地线连接,把需要保护的电路置于其中,使外部干扰电场不影响其内部电路,反过来,内部电路产生的电场也不会影响外电路。例如传感器测量电路中,在电源变压器的初级和次级之间插入一个留有缝隙的导体,并把它接地,可以防止两绕组之间的静电耦合。4.3.2电磁屏蔽对于高频干扰磁场,利用电涡流原理,使高频干扰电磁场在屏蔽金属内产生电涡流,消耗干扰磁场的能量,涡流磁场抵消高频干扰磁场,从而使被保护电路免受高频电磁场的影响。若电磁屏蔽层接地,同时兼有静电屏蔽的作用。传感器的输出电缆一般采用铜质网状屏蔽,既有静电屏蔽又有电磁屏蔽的作用。屏蔽材料必须选择导电性能良好的低电阻材料,如铜、铝或镀银铜等。949-07-15240INVERTERSETB836E0163-2-2GPD402.75H/230B836E0163-3-1GPD402.75H/230B836E0165JUSPEED-FBOARDCA133-3F/VCONVERTERCA141-1DUALPOWERSUPPLYCA224ISOLATIONBOARDCACR-15-YU1SERVOPACKCACR-1R44SFBPCBCACR-IR151515EBSERVOPACKCONTROLCACR-IR151515FBSERVOPACKCONTROLCACR-PR02AA4AHSERVOPACKCONTROLCACR-SR01AC1ER100W200VSERVOCACR-SR02AC1ER200W200VSERVOCACR-SR03AC1ER300W200VSERVOCACR-SR03AC2ER300W100VSERVOCACR-SR03BB1AFSERVOPACKCONTROLCACR-SR03BB1AMSERVOPACKCONTROLCACR-SR03BB1CSSERVOPACKCONTROLCACR-SR05AC1ER500W200VSERVOCACR-SR05AC1FR500W200VSERVOCACR-SR05AZ1SRSERVOPACKCONTROLCACR-SR05BB1BFSERVOPACKCONTROLCACR-SR05BB1ESSERVOPACKCONTROLCACR-SR07AC1ER700W200VSERVOCACR-SR07BB1AMSERVOPACKCONTROLCACR-SR07BB1BMSERVOPACKCONTROLCACR-SR10BB1AFSERVOPACKCONTROLCACR-SR10BB1AMSERVOPACKCONTROLCACR-SR10BB1BFSERVOPACKCONTROLCACR-SR10BB1CSSERVOPACKCONTROLCACR-SR10BE12FSERVOPACKCONTROLCACR-SR10BE12GSERVOPACKCONTROLCACR-SR10SZ1SFSERVOPACKCONTROL)
