摘要
10kV电压等级的配电网,主要是架空线路。断路器用的电流保护控制器很容易受到电磁辐射、静电感应、静电放电、高频噪声等的电磁干扰。为了验证该控制器是否具有在户外稳定工作的可靠性,将断路器用电流保护控制器进行了电磁兼容试验,试验结果表明,所采取的抑制方法有效地抑制了高频干扰。
The current protection controller of circuit-breaker for 10 kV aerial line often suffers electromagnetic interference by electromagnetic radiation, electrostatic induction, static discharge, canaries etc. EMC experiments about the current protection controller were done to verify whether the controller worked outdoor stably and reliably or not. The experimental result indicates that inhibition method restrains high-frequency interference to some extent availably.
