电流互感器有源电子补偿装置的研制

The Manufacture of CTElectronic Compensation Derice with Power

叙述ＤＬＢ－０２型电流互感器有源电子补偿装置，采用电子技术，从外部补偿电流互感器的误差。用于１０ｋＶ～２２０ｋＶ电磁式电流互感器的补偿，由于采用了模拟补偿原理，从而使调试方便，具有较好的补偿效果。装置装设在被补偿电流互感器的二次侧，具有安全、可靠、安装方便的特点。使用该装置，可使被补偿ＣＴ准确度从０．５级提高到０．２级以上。

DLB 02 CT electronic compensation Device with power,which uses electronic technology,compensates CT error from the outside It can be used to compensate 10 kV～220 kV electro magnetic CT Taking use of analogue compensation principle makes it convinient for adjusting and testing with a better compensation effect It is safe and reliable,also convenient for installation because it is set at the seconday side of the compensated CT It can enhance the compensated CTs accuracy from 0 5 grade up aboue 0 2 grade
