摘要:
低压线路接触不良放电与其影响因素之间的关系一直是重点研究问题,通过理论分析以放电量作为反映接触不良放电状态的指标,选取接触间隙和负荷电流两个主要影响因素进行试验研究和回归分析。试验研究表明,接触不良放电量随负荷电流的增大而缓慢增加,随接触间隙增大而快速增加;回归分析发现,放电量与负荷电流的线性拟合以及与3次接触间隙的拟合均具有很高的拟合优度,表明放电量与负荷电流呈线性关系,与接触间隙呈三次函数关系。研究结果为接触不良放电防范提供理论依据。
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.
