The invention relates to a moisture absorbing device for a closed space of a solid insulating ring network cabinet, comprising an upper insulating box and a lower insulating box, and a closed space is formed between the upper insulating box and the lower insulating box; the feature is that a drying box is installed on the lower insulating box , a bagged desiccant is placed in the drying box; a moisture absorption gap is arranged inside the lower insulating box, and the moisture absorption gap communicates with the closed space and the drying box. An O-ring is provided at the connection between the drying box and the lower insulation box, and the O-ring is placed in a concave groove on the drying box. The drying box is fixed on the lower insulating box by fixing screws. The drying box is a transparent drying box. The invention can effectively dehumidify the air inside the solid insulation ring network cabinet, and can quickly, safely and conveniently replace the moisture absorbing device.
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...
