摘要/Abstract

摘要： 为降低避雷器的运维工作量，基于反时限原理采用双球隙设计了配电线路避雷器的分频式脱离器，能可靠区分流过避雷器的高、低频电流。在避雷器出现绝缘受损时，能自动可靠脱离，便于运维人员发现故障点。该脱离器采用电感与大球隙并联，实现了泄漏电流的同路分频。在冲击或高频电流下，泄漏电流流过大球隙，脱离器不动作；在工频或低频电流下，泄漏电流流过电感。当电流大于40 mA且小于0.5 A时，采用电阻发热动作；当电流大于0.5 A时，采用小球隙击穿动作，避免了电阻被烧坏使脱离器拒动的问题。且对于这两种情况，泄漏电流越大，脱离器均动作越快。通过ATP模型仿真，确定了电感的参数及大球隙的动作特性。数值仿真及实验结果表明了该脱离器在避雷器绝缘受损时，能可靠动作。

Abstract: In order to reduce the workload of the operation and maintenance of distribution line arresters, this paper designs a frequency-dividing disconnector using double sphere gaps based on the inverse time principle, which can reliably shunt high and low frequency current. The disconnector can be separated automatically and reliably while the insulation of the arrester is damaged, and the fault section can be found. The disconnector realizes the mechanism of frequency division of leakage current by using inductance and large sphere gaps in parallel. Under the impulse or high frequency, the leakage currents flow through the big sphere gap and the disconnector would not act. While under the power or low frequency, the leakage currents flow through the inductor. When the current takes value from 40 mA to 0.5 A, resistance heating action would be utilized. When the current is larger than 0.5 A, the small sphere gap breakdown action would be adopted, which avoids the mal-operation of disconnector due to burned out resistance. In these two cases, the greater the leakage current, the faster the disconnector operates. Through the ATP model simulation, the parameters of the inductance and the operating characteristics of the large gap can be determined. The numerical simulation and experimental results show that the disconnector can operate reliably when the insulation of the arrester is damaged.
