磁场环路积分的等价解环

Equivalent uncoupling of magnetic field Integral loop

为解决光学电流互感器(OCT)抵卸磁场干扰与运行可靠性的矛盾问题,在提炼了磁场积分环路的等价解环条件的基础上,提出了磁场积分环路的正交解环法和零和解环法.证明了3个基本的解环定理:正交解环定理、零和解环定理和均匀磁场矩形环路的解环定理.提出的正交解环法和零和解环法可以将安培环路定律等价地推广到非环路情况,并给出了实例.该研究为解决光学电流互感器在电力系统的实际应用中抵御磁场干扰与运行稳定性的矛盾问题奠定了理论基础.

To overcome the conflict between anti-magnetic interference ability and operation stability for optic current transformers（ OCT）, an orthogonal uncoupling method and a difference uncoupling method for magnetic filed integral loop are proposed based on magnetic field integral loop equivalent uncoupling conditions. Orthogonal uncoupling theorem, difference uncoupling theorem and uniform magnetic filed rectangular loop uncoupling theorem are also proved. These uncoupling methods proposed in this paper can expand the Ampere loop theorem equally to un-loop situations. This study provides the fundamental theories to solve the contradictions between anti-magnetic interference ability and operation stability, of optic current transformers in practical applications.
