一、三相四线制和三相五线制符号含义解答:


SANXIANGWUXIANZHI:R HUANG、SLV、THONG、NLANHUOHEI、DIHUANGJIALVSHUANGSEXIAN; 

辽宁11选5SANXIANGSIXIANZHI:R HUANG、SLV、THONG、NLANHUOHEISEXIAN; 

SANXIANGSIXIANZHI:R HUANG、SLV、THONG、DIHUANGJIALVSHUANGSEXIAN; 

SANXIANGSIXIANZHI(SHUYUTN-CJIEDIXITONG):XIANGXIANA、B、C,BAOHULINGXIANPEN,PENXIANSHANGYOUGONGZUODIANLIUTONGGUO,PENZAIJINRUYONGDIANJIANZHUWUCHUYAOZUOZHONGFUJIEDI;

二、三相四线制比三相五线制少了一根线输电线路,即少了一根地线:

三、三相五线制的性能特点就在于两根"零线"上:


1、ZAIBIJIAOJINGMIDIANZIYIQIDEDIANWANGZHONGSHIYONGSHI,RUGUOLINGXIANHEJIEDIXIANGONGYONGYIGENXIANDEHUA,DUIYUDIANLUZHONGDEGONGZUOLINGDIANHUIYOUYINGXIANGDE,SUIRANLILUNSHANGTAMENDOUSHI0DIANWEIDIAN,RUGUOOUERYOUYIGEDIANYONGMAICHONGCHONGJIDAOGONGZUOLINGXIAN,ERLINGXIANHEDIXIANQUEMEIYOUFENKAI,BIRUZHEIZHONGMAICHONGQUESHIYINWEIXIANGXIANLOUDIANYINQIDE,ZAIRUYOUXIEDIANZIDIANLUZHONGRUGUOLINGDIANPIAOYIXIANXIANGYANZHONGDEHUANEIMEDIANQIWAIQIAOJIUKENENGHUIDAIDIAN,KENENGHUISUNHUAIDIANQIYUANJIANDE,SHENZHISUNHUAIDIANQI,ZAOCHENGRENSHENANQUANDEWEIXIAN;

四、在三相四线制供电系统中,把零干线的两个作用分开,即一根线做工作零线(N),另外用一根线专做保护零线:


 GONGZUOLINGXIANNYUBAOHULINGXIANPECHUZAIBIANYAQIZHONGXINGDIANGONGTONGJIEDIWAI,LIANGXIANBUZAIYOURENHEDEDIANQILIANJIE。YOUYUGAIZHONGJIEXIANNENGYONGYUDANXIANGFUZAI,MEIYOUZHONGXINGDIANYINCHUDESANXIANGFUZAIHEYOUZHONGXINGDIANYINCHUDESANXIANGFUZAI,YINERDEDAOGUANGFANDEYINGYONG。ZAISANXIANGFUZAIBUWANQUANPINGHENGDEYUNXINGQINGKUANGXIA,GONGZUOLINGXIANNSHIYOUDIANLIUTONGGUOQIESHIDAIDIANDE,ERBAOHULINGXIANPEBUDAIDIAN,YINERGAIGONGDIANFANGSHIDEJIEDIXITONGWANQUANJUBEIANQUANHEKEKAODEJIZHUNDIANWEI。
