摘要
目前,市面上的变压器铁心接地电流监测装置工作时都需要外接电源,另外价格高昂.为此设计一种无源型变压器铁心接地电流越限告警电路,这种电路不再需要外接电源,同时具有越限告警电流精准稳定、运行安全可靠、电路简单、体型小巧、造价低廉等优势,具备良好的应用及推广条件.
Abstract
The current commercial transformer core grounding current monitoring device requires an external power supply when working.And the price is high.Design a passive transformer core grounding current over limit alarm circuit for this purpose.This circuit no longer requires an external power supply.At the same time,it has outstanding advantages such as accurate and stable over-limit alarm current,safe and reliable operation,simple circuit,compact size,and low cost.Possess good application and promotion conditions.
