HFO-1234ze（E）/CO₂混合气体工频击穿及分解特性实验研究

Gaoya dianqi
近年来，由于HFO-1234ze（E）具备良好的环保特性和优良的绝缘性能，被认为有较大潜力应用于中低压设备中。目前针对该气体的试验探究相对比较少。文中首先计算了不同气压下HFO-1234ze（E）/CO2混合气体的液化温度，然后利用气体绝缘性能测试平台，分别探究了气压、混合比对HFO-1234ze（E）/CO2混合气体绝缘特性的影响，并讨论实际工程应用中的最优混合比和气压值，再采用气相色谱质谱联用仪（GC-MS）对分解产物进行定性分析，同时对分解产物进行了仿真计算。研究结果表明在不同均匀场的条件下 ...
