摘要:

接触器线圈去激励过程中会产生反向瞬态电压,对线圈控制回路造成危害。基于稳压二极管和压敏电阻分别构建了瞬态电压抑制电路,对比分析了不同钳位电压下的线圈电压波形及释放时间特性。研究发现,钳位电压降低会显著延长接触器释放时间,且钳位电压相同的情况下,压敏电阻抑制电路相较稳压二极管抑制电路可缩短释放时间。

Abstract:

Reverse transient voltage is generated during the de-energization of contactor coils,which may cause damage to the coil control circuit.Transient voltage suppression circuits are constructed respectively based on Zener diodes and varistors.The coil voltage waveforms and release time characteristics under different clamping voltages are compared and analyzed experimentally.It is found that the decrease of clamping voltage significantly prolongs the contactor release time,and under the same clamping voltage,the varistor-based suppression circuit results in a shorter release time compared with the Zener diode-based suppression circuit.

Key words: electromagnetic coil, transient voltage, Zener diode, varistor, release time
