Abstract

A field cabinet body anti-condensation device for an electric power system is characterized in that the field cabinet body anti-condensation device for the electric power system comprises a bottom frame supporting structure, an exhaust duct and an exhaust device, wherein a cabinet body is installed on the bottom frame supporting structure and the bottom frame supporting structure is placed in an underground pit; the exhaust duct is installed beside the bottom frame supporting structure, the lower end of the exhaust duct is 10 cm to 15 cm away from the bottom of the pit, and the upper portion of the exhaust duct is 20 cm to 30 cm higher than the cabinet body; the exhaust device is installed on the upper portion of the exhaust duct. The field cabinet body anti-condensation device for the electric power system has the advantages that the condensation phenomenon that cold air inside the cabinet body condenses into ice crystal attached to a device is avoided and a guarantee is provided for device safety.

Description

technical field [0001] The invention relates to moisture-proof equipment for an outdoor cabinet, in particular to an anti-condensation device for an outdoor cabinet of a power system. Background technique [0002] The winter in the northern region is severe and long, and the outdoor temperature is extremely low. Equipment such as ring network cabinets, branch boxes, and switch stations are placed above the cable wells, all of which have relatively deep foundations. When winter comes, the part below the permafrost layer in the well is warm and humid, so that the moist air will rise into the box. When encountering cold air, it condenses into ice crystals and attaches to the equipment to form condensation, which poses a great hidden danger to the safety of the equipment. Contents of the invention [0003] The object of the present invention is to effectively solve the condensation problem of the outdoor cabinet, and especially provides an anti-condensation device for the out...
