摘要:
低壓線路接觸不良放電與其影響因素之間的關系一直是重點研究問題,通過理論分析以放電量作為反映接觸不良放電狀態的指標,選取接觸間隙和負荷電流兩個主要影響因素進行試驗研究和回歸分析。試驗研究表明,接觸不良放電量隨負荷電流的增大而緩慢增加,隨接觸間隙增大而快速增加;回歸分析發現,放電量與負荷電流的線性擬合以及與3次接觸間隙的擬合均具有很高的擬合優度,表明放電量與負荷電流呈線性關系,與接觸間隙呈三次函數關系。研究結果為接觸不良放電防范提供理論依據。
Abstract:
The relationship between poor contact discharge and the influence factor is a key research issue on low voltage wire. Discharge capacity has been chosen to reflect the discharge condition through theoretical analysis. And two main influence factors, load current and contact gap, have been selected for experimental study and regression analysis. The experimental results show that discharge capacity has a low increasing with the increase of load current, and has an obvious increasing with the increase of contact gap. The regression analysis shows that the linear fitting between contact gap and load current has a high goodness of fit, and the cubic polynomial fitting between contact gap and contact gap has a high goodness of fit, which means discharge capacity has linear relation with load current and cubic polynomial relation with contact gap. The results can be used as references for discharge prevention on low voltage wire.
