摘要
介绍了一种基于12kV紧凑型常压空气绝缘供电柜采用的不可触及隔室全密闭结构时环境因素导致隔室内外空气进行自主交换的呼吸装置。该装置利用有益的电子组件对外部高湿度空气进入隔室内部时进行有效的干燥处理,使得常规的空气绝缘供电柜在极大缩小占地面积与安装体积的前提下获得更高的环境耐受能力与运行安全性能。设计方案采用了电容式传感器作为取能元件并采用间歇式供电降低能耗,不仅有着一定的技术性价比,也对这一电压等级下环保气体供电柜的应用提供了稳定可靠低成本选型方案。
This paper introduces a breathing device based on 12kV compact atmospheric pressure air-insulated switchgear which adopts an inaccessible compartment with a fully enclosed structure and environmental factors lead to autonomous exchange of air inside and outside the compartment.The device uses beneficial electronic components to effectively dry the external high-humidity air when it enters the interior of the compartment;this allows conventional air-insulated switchgear to achieve higher environmental tolerance and operational safety performance on the premise of greatly reducing the footprint and installation volume.The design uses capacitive sensors as energy-absorbing components and intermittent power supply to reduce energy consumption.It not only has a certain technical cost performance,but also provides a stable and reliable low-cost type selection solution for the application of environmentally friendly gas power cabinets at this voltage level.
