The invention discloses an intelligent dehumidifying and cooling high-
voltage switch cabinet for a photovoltaic field. The intelligent dehumidifying and cooling high-
voltage switch cabinet comprises a cabinet body, an
intelligent environment sensing device and a composite dehumidifying and cooling device. The
intelligent environment sensing device collects environment data in the cabinet in real time through a temperature sensor, a
humidity sensor, an illumination intensity sensor and an air
pressure sensor, and the environment data is processed by the controller and then controls the combined type dehumidifying and cooling device to operate. The combined type dehumidifying and cooling device comprises various assemblies, various dehumidifying and cooling states can be achieved, and the primary dehumidifying rotating wheel and the advanced dehumidifying rotating wheel are matched with the
heating system to complete dehumidifying and regenerating circulation. A fault diagnosis and emergency
processing module is further arranged, faults can be predicted, and the
operation mode can be automatically adjusted. Compared with the prior art, intelligent sensing, accurate regulation and control, high efficiency and energy saving are achieved, the fault risk caused by the temperature and
humidity problem of the photovoltaic field high-
voltage switch cabinet is effectively solved, and safe and stable operation of an
electric power system is guaranteed.
