均压环断裂倾斜对复合绝缘子电场影响的研究

Gaoya dianqi
为了研究均压环断裂和倾斜对复合绝缘子电场和电位的影响，以FXB3-110/100型复合绝缘子为研究对象，采用有限元分析法在ANSYS中建立复合绝缘子物理模型并进行仿真。通过改变均压环断裂位置和倾斜角度对其进行建模，再通过有限元分析法研究其对电场分布的影响。结果表明：不论高压侧还是低压侧的均压环的断裂和缺失，都会使该侧的场强激增而对侧的场强骤降。均压环断裂使得电位向两端集中，当均压环全部断裂致使脱落时，高低压侧前3%～5%的泄露距离承担了60%的电压降。发生复合绝缘子均压环的倾斜时 ...

岩体导流性能是影响深地资源开发效率的重要因素。为了研究压裂施工参数对岩体导流特性的影响规律，基于基质-裂缝网络的变形-渗流耦合行为，通过将压裂储层划分为气体单相渗流的非改造区、两相渗流的改造区及离散裂缝网络，构建了耦合多区域渗流行为的数值计算模型，实现了基质-裂缝在力学变形与多相渗流过程中的全耦合描述，能更真实地表征裂缝动态张开闭合条件下的力学-渗流响应特征。对考虑气体吸附效应以及水力压裂相关因素在页岩气产量提升方面的影响进行了研究，揭示了压裂储层的产能提升机理 ...
