Rheostat circuit for eliminating coil surge

Abstract

消除线圈浪涌的变阻器电路,其涉及开关柜控制电路技术领域。其特征在于它包含变阻器(1)和接触器(2),变阻器(1)并联于接触器(2)两端。本发明结构简单,能有效的消除接触器线圈开关产生的过电压,增加了电路的安全性、稳定性和连续性。
A rheostat circuit for eliminating coil surge relates to the technical field of a switch cabinet control circuit. The rheostat circuit is characterized in that the rheostat circuit comprises a rheostat (1) and a contactor (2), wherein the rheostat (1) is connected in parallel to the two ends of the contactor (2). The rheostat circuit is simple in structure and can effectively eliminate overvoltage generated by a contactor coil in the on and off process, and thus safety, stability and continuity of the circuit are enhanced.
