Abstract

The invention discloses a dehumidification and anti-condensation intelligent control system and method for a ring main unit. The system is based on the thermoelectric refrigeration technology and the wireless sensor network technology, a fuzzy fractional order PID controller is adopted, the temperature and the humidity of the working environment are monitored in real time, and intelligent control dehumidification is achieved. In combination with a wireless sensor network platform with the complete function, a user can achieve the purposes of holding a device for polling in a field and remotely and online monitoring the state of equipment in real time. The condensation dehumidification device can effectively reduce the humidity of space air, the condensation phenomenon is avoided, and the condensation dehumidification device has the advantages of being small in size, low in operation cost, long in service life and high in reliability, and is widely applied to dehumidifying various closed cabinets such as a switch cabinet, a power distribution cabinet and a terminal box.

Description

technical field [0001] The invention belongs to the technical field of temperature and humidity control of electric power equipment, and in particular relates to a dehumidification and anti-condensation intelligent control system and method of a ring network cabinet. Background technique [0002] Various power and communication equipment such as switch cabinets, electrical control cabinets, terminal boxes, and power boxes are widely used in the power grid. When the air humidity in the cabinet is too high, the switch circuit will be corroded, and the contact resistance of the plug-in at the component joint will increase, which will lead to equipment function failure and failure, and may cause breakdown of poorly sealed components. When dew condenses on the surface of electronic components, it will cause a short circuit of the components, which may damage the equipment and threaten the safe operation of the power grid. [0003] Install a condensation dehumidification device i...
