摘要

为研究新型分体式有载分接开关(OLTC)电弧故障时的应力分布并验证其布置可靠性

基于电弧能量和电弧故障的产气特性

计算了电弧故障起始过程的冲击压力与气泡膨胀阶段的压力; 进而建立电弧故障的压力波传输模型

采用声固耦合仿真方法对压强场-应力场的耦合作用进行计算

实现了流体压力波与固体弹性波的相互转换; 同时构建分体式OLTC内部燃弧故障的压力传播模型

得到了切换油室和分体油箱的内部压强和结构应力分布特征。计算结果表明:电弧故障后油室顶部和底部的压强峰值分别为1.59、2.95 MPa

对应的油室顶部和底部结构的应力峰值分别为90、440 MPa

明显存在油室底部开裂风险; 在油室底部泄漏的情况下

油箱顶部应力峰值超过250 MPa会造成油室底部破坏

从而严重威胁油箱结构的可靠性。相关结论可为分析OLTC油室结构破裂故障和完善新型OLTC分体式布置的设计提供理论依据。

Abstract

To study the stress distribution in the new separate on-load tap changers(OLTC)during arc faults and verify the reliability of OLTC separate arrangement

the impact pressure during arc fault initiation and bubble expansion stage are calculated based on arc energy and gas production characteristics. The pressure wave transmission model of the arc faults is established. The acousto-solid coupling simulation method is used to calculate the coupling effect of pressure field and stress field

realizing the conversion between fluid pressure wave and solid elastic wave. Additionally

the pressure transmission model for internal arc faults in separate OLTCs is established to obtain the internal pressure and structural stress distribution characteristics of switching oil chamber and split oil tank. The results show that the peak pressures at the top and bottom of the oil chamber after the arc fault are 1.59 MPa and 2.95 MPa respectively. The corresponding peak structural stresses at the top and bottom of the oil chamber are about 90 MPa and 440 MPa respectively

presenting a risk of cracking at the bottom of the oil chamber. In the case of leakage at the bottom of the oil chamber

the peak stress of over 250 MPa at the top of the oil chamber will result in the damage at the bottom of the oil chamber

further threatening the reliability of the oil chamber structure. The conclusions of this paper can provide a theoretical basis for the failure analysis of OLTC oil chamber structure rupture and the refinement of the design of new OLTC separate arrangement.
