Abstract

The invention relates to a temperature and humidity control device for a transformer substation. The device comprises a temperature sensor, a humidity sensor, an exhaust draught fan , an air inlet draught fan and a control cabinet, wherein the control cabinet is installed in the transformer substation, the temperature sensor and the humidity sensor are connected with the control cabinet through data lines, and the exhaust draught fan and the air inlet draught fan are controlled through the control cabinet; a processing device is arranged in the control cabinet and connected with the temperature sensor and the humidity sensor, and the processing device is connected with the air inlet draught fan and the exhaust draught fan through relays. The device is reasonable in structure, convenient to use and capable of monitoring the environmental condition in the transformer substation in real time, reasonably adjusting the work state of the draught fans and guaranteeing the service life to the maximum extent.

Description

technical field [0001] The invention relates to a temperature and humidity control device for a substation. Background technique [0002] In order to ensure that the operating environment temperature of high-voltage indoor substation equipment is suitable, exhaust fans are widely used in substations. The exhaust fan automatic control box currently used only has the function of temperature regulation, and its sensitivity is poor. After the fan is put into operation, it is in the running state for a long time, which greatly reduces the service life. In addition, in the actual operation of substation equipment, there are problems such as excessive humidity in the high-voltage room and condensation in the cabinets of high-voltage equipment, especially central cabinets, which affect the normal operation of the equipment and even fail. Contents of the invention [0003] In order to solve the deficiencies in the above technical problems, the object of the present invention is t...
