消除誤差的方法兩年內(nèi)我們探索了導線、分數(shù)匝、電容、電感、電阻絲等對正比差補償方法。1995年底，我們終于找到了可使電流互感器正、負比差都明顯減小的技術(shù)方案。例如23號200／5的電流互感器，當母線穿心一匝，一次電流為180A時，二次顯示194A，正比差為14A，一次電流為5A，二次示數(shù)為0A，負比差為5A。利用這種技術(shù)方案，可以使該電流互感器一次電流從0A到額定電流的整個區(qū)間，正比差為0A，負比差額定值為lA，從而發(fā)現(xiàn)了降低電流互感器比差的技術(shù)方案。電流互感器的負載特性當二次測所接負載阻抗遠大于銘牌上標定的阻抗時，電流互感器是一恒壓源。例如9號150／5互感器，銘牌上標定的阻抗為0．2Ω。當一次電流為150A，二次開路時，用MFl73型萬用表交流10V檔，精度為9kΩ／V，相當于在二次回路上串聯(lián)90kΩ的電阻，測得其電壓為2．6V；當二次測并接15Ω300磁場變阻器，分別取阻值15Ω、7．5Ω、3．75Ω時，二次電壓仍為2．6V；當取1．875Ω時二次電壓才降為2．55V，有力地證明了上述結(jié)論。當外阻遠小于標定阻抗時，電流互感器接近一恒流源，上海二工電流互感器ALH-0.66 100-80II。例如9號150／5互感器，上海二工電流互感器ALH-0.66 100-80II，將一次電流調(diào)至135A。上海喆和定制銷售西門子APT（原上海二工）ALH-0，上海二工電流互感器ALH-0.66 100-80II.66 80*50II電流互感器.上海二工電流互感器ALH-0.66 100-80II</p><div
