Abstract

The invention discloses process level equipment of an intelligent substation, and aims to provide an outdoor cabinet structure which can effectively avoid the problem that the process level equipmentis abnormal caused by excess temperature of the process level equipment and also can avoid the problem that normal operation of the process level equipment is influenced by external water vapor entering into the process level equipment. The process level equipment comprises a cabinet body, a heat dissipating device and a self-switching type dehumidifying mechanism, wherein a cabinet body air outlet is formed in the top surface of the cabinet body, and a cabinet body air inlet is formed in the lower part of the side surface of the cabinet body; the heat dissipating device comprises an exhaust fan arranged on the cabinet body air outlet; and the self-switching type dehumidifying mechanism comprises a drying box body, a box body air return inlet formed in the top surface of the drying box body, an air return pipeline for connecting an air outlet of the exhaust fan and the box body air return inlet, a first vertical valve sleeve and a second vertical valve sleeve which are arranged insidethe drying box body, a first vertical dehumidifying cylinder slidably arranged inside the first vertical valve sleeve and a second vertical dehumidifying cylinder slidably arranged inside the second vertical valve sleeve.

Description

technical field [0001] The invention relates to the field of intelligent substations, in particular to a process layer device of an intelligent substation. Background technique [0002] With the rapid development of smart substations, process-level equipment has problems with adaptability and reliability in outdoor operating environments; especially when the ambient temperature is high, the number of process-level equipment operation alarms increases significantly. In many intelligent substations, there have been accidents in which the temperature of the process layer equipment was too high, resulting in device abnormalities, which eventually led to protection malfunctions and large-scale power outages. Contents of the invention [0003] The first purpose of the present invention is to provide a smart substation process-level equipment that can effectively improve the problem of equipment abnormality caused by excessive temperature in the process-level equipment, which eve...
