Moisture-proof and condensation-proof control method for indoor station

Abstract

The invention discloses a moisture-proof and condensation-proof control method for an indoor station. The moisture-proof and condensation-proof control method comprises the steps of selecting an indoor temperature and humidity control mode, and configuring an indoor temperature and humidity regulation-control range according to a season and the temperature and humidity control mode; acquiring indoor temperature and humidity, outdoor temperature and humidity, a water logging opening-closing state and an access opening-closing state of the indoor station; comparing the acquired outdoor temperature and humidity with a local air dew point hygrometer, looking up a dew point temperature, comparing the acquired indoor temperature and humidity with the dew point temperature, and recording a comparison result every time; and starting a dehumidifier to dehumidify while judging that the indoor temperature achieves the dew point temperature or judging that the indoor temperature has a trend of approaching to the dew point temperature by virtue of recent multiple comparison results, wherein an air conditioner automatically heats or refrigerates according to the season to break the dew point temperature, thereby preventing indoor condensation. The moisture-proof and condensation-proof control method disclosed by the invention is moisture-proof and condensation-proof, and capable of furthest saving energy, guaranteeing safe and normal long-time running of electrical equipment, and lowering a maintenance cost.

Description

technical field [0001] The invention relates to a moisture-proof and condensation-proof control method for an indoor station. Background technique [0002] A clean and dry operating environment is the basic guarantee for ensuring the long-term safe, stable and reliable operation of electrical equipment, and it is also an important link to ensure the long-term safe operation of the power system. [0003] At present, the design of substations and switching stations mostly adopts indoor station design. In order to ensure reliability and safety, the lead wires of the power inlet and outlet intervals and the main transformer interval are basically connected in the form of closed busbar bridges, and the cable trench inlet and outlet wires are laid. The circulation is not smooth, and moisture is easy to enter due to reasons such as poor sealing and underground moisture. Generally, the relative humidity of the trench is between 70% and 95%. The moisture generated by the trench evapo...

AI Technical Summary

Problems solved by technology

Fan-type dehumidifiers exchange with dry air from the outside through air convection to reduce indoor humidity. When the ambient humidity is high, the problem of condensation cannot be solved, and it is easy to cause dust and dirt to enter the cabinet.
