The invention relates to a confined space moisture absorption device of a solid insulation full-closed loop network cabinet. The confined space moisture absorption device comprises an upper insulating box and a lower insulating box. A confined space is formed between the upper insulating box and the lower insulating box. The confined space moisture absorption device is characterized in that a drying box is installed on the lower insulating box and contains bagged drying agents; a moisture absorption notch is formed in the inner side of the lower insulating box and communicated with the confined space and the drying box. An O-shaped ring is arranged at the joint of the drying box and the lower insulating box and placed in a groove in the drying box. The drying box is fixed to the lower insulating box through a fixing screw. The drying box is a transparent drying box. By means of the confined space moisture absorption device, air inside the solid insulation full-closed loop network cabinet can be effectively dehumidified, and the moisture absorption device can be rapidly, safely and conveniently replaced.
Description
technical field [0001] The invention relates to a solid insulating ring network cabinet, in particular to a moisture absorbing device for a closed space of the solid insulating ring network cabinet. Background technique [0002] With the progress of smart grid development, the widespread use of smart power distribution equipment has led to a rapid improvement in power transmission and distribution technology, especially in response to the agricultural and social impacts of El Niño caused by the greenhouse effect. The use of solid insulated ring network cabinets can reduce the impact of the greenhouse effect caused by the use of sulfur hexafluoride, and can also play a positive role in the distribution of green and environmentally friendly power. The key to the insulation of ring network cabinets with solid insulation is to reduce the impact of humid gas on the insulator and the insulation requirements such as short circuits. Due to the existence of a large amount of humid g...
