HFO-1234ze(E)(trans-1,3,3,3-tetrafluoropropene, chemical formula: C 3 H 2 F 4 ) is an extremely environmentally friendly SF 6 alternative gas with high electrical strength. In this paper, the partial discharge (PD) characteristics of HFO-1234ze(E)/N 2 mixtures were studied using the gas insulation test platform. The PD inception voltage of insulating gas under positive and negative half cycles of power frequency was tested. Using SF 6 /N 2 mixtures as a control group, the effects of electrode spacing, mixing ratio and pressure on the insulation performance of HFO-1234ze(E)/N 2 mixtures were explored. The test results show that the PD inception voltage of the negative half-cycle of pure HFO-1234ze(E) under short electrode spacing can reach 0.96–1.04 times of pure SF 6 under different pressures; the PD inception voltage of 40%HFO-1234ze(E)/60%N 2 mixtures at 0.3 MPa is 0.67–0.89 times t...

HFO-1234ze（E）/ N 2混合物中的局部放电特性的研究

HFO-1234ze（E）（反式-1,3,3,3-四氟丙烯，化学分子式：C 3 H 2 F 4）是一种极高环保的SF 6替代气体，具有较高的电强度。在本文中，使用气体绝缘测试平台研究了HFO-1234ze（E）/ N 2混合物的局部放电（PD）特性。测试了在电源频率的正负半周下绝缘气体的PD起始电压。以SF 6 / N 2混合物为对照组，研究了电极间距，混合比和压力对HFO-1234ze（E）/ N 2混合物的绝缘性能的影响。测试结果表明，在短电极间距下，纯HFO-1234ze（E）负半周的PD起始电压在不同压力下可以达到纯SF 6的0.96-1.04倍。
