The research and practice of high voltage cubicle early warning based on Gas Component Analysis

The monitoring of heat generation inside closed high-voltage switch cabinet is a technical problem which affects safe production at present. This paper analyses the present early warning technique for switch cabinet at home and abroad and proposes the high-voltage switch cabinet elements based on gas composition analysis, and deeply analyses the principle of temperature measurement using laser light scattering. This paper introduces the structure of high-voltage switch cabinet early warning device based on gas composition analysis which has run into operation and the function of each module. Meanwhile, this paper summarizes achievements and prospects the next major research.
