摘 要：針對變電站日常基建驗收、例檢維護中發(fā)現(xiàn)的電容器電壓保護二次接線錯誤導致電容器本體電壓保護誤動或拒動的現(xiàn)象，根據(jù)電容器差壓及不平衡電壓保護二次接線原理及檢測方法，研制出一套電容器差壓或不平衡電壓保護回路二次接線核對器，用來替代傳統(tǒng)的二次回路芯線核對方法。對核對器系統(tǒng)構(gòu)架及軟硬件設(shè)計流程進行了闡述，實際應(yīng)用表明，該核對器使用簡單、測試結(jié)果準確有效，并縮短現(xiàn)場測試時間。

Abstract: Aiming at the phenomenon of the capacitor voltage protection misoperation or refusing action in the transformer substation construction acceptance and check maintenance because of the voltage protection secondary wiring errors, this paper developed a set of secondary wiring verifier based on the secondary wiring principle and testing method for the differential pressure or voltage imbalance protection, to replace the traditional secondary circuit core wire verification method. This paper expounded the software and hardware design flow of verifier systematic framework. The practical application shows that this verifier is simple to be used and the test results are accurate and effective with shortening testing time.
Key words: capacitor; voltage protection; verifier
