摘要

Abstract

HFO-1336mzz(E) (HFO-butene) is regarded as a promising eco-friendly insulating gas to replace sulfur hexafluoride (SF<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">6) used in medium-voltage gas insulated equipment (MV-GIE). In this paper

we systematically explored partial discharge properties of HFO-butene/CO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2 gas mixture by revealing partial discharge inception voltage (PDIV)

partial discharge extinction voltage (PDEV)

and phase resolved partial discharge (PRPD) pattern under different mixing ratios

and gas pressure conditions. Meanwhile

the action and influence mechanism of “space charge layer” on PD distribution properties of HFO-butene/CO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2 is proposed. We found PDIV of HFO-butene/CO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2 demonstrated linear-saturation increase trend with mixing ratio and gas pressure

which is equivalent to that of SF<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">6 as HFO-butene content reaches 25%~130%. In addition

there showed “double peak” phenomenon in the <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$n-\varphi$ spectrum of HFO-butene/CO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2 with low HFO-butene content and gas pressure

which is ascribed to the shielding effect of the stable “space charge layer” nearby the needle electrode that improves non-uniformity of the electric field. Corresponding results revealed PD characteristics of HFO-butene/CO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2 gas mixture and brought guidance to development of brought guidance based MV-GIE.
