Application of Fourfaith dehumidifier in power distribution equipment
Requirement Analysis
The humidity in some areas is high, the weather temperature changes greatly, the bottom of the switch cabinet is wet, and some cable trenches even have accumulated water;
Some switchgears are placed in the basement with high humidity, and the temperature inside the cabinet, especially the temperature close to the ground, is lower than the ambient temperature;
Some equipment is temporarily out of service, and the ambient temperature in the electrical cabinet is lower than the ambient temperature, and condensation is likely to form on its surface.
Solution Introduction
The application scheme of the Fourfaith dehumidifier in the power distribution equipment adopts the semiconductor refrigeration and dehumidification method, actively sucks the humid air in the enclosed space into the dehumidification air duct under the action of the fan, and the water vapor in the air passes through the semiconductor refrigeration mechanism to condense into water, and then passes through the water guide Out of the cabinet, the ideal dehumidification effect can be achieved. By reducing the water content in the air, the scheme reduces the relative humidity and absolute humidity at the same time, hardly raises the temperature, does not produce the negative effects of temperature differences, fundamentally eliminates or reduces the occurrence of accidents, and does not accelerate the cabinet due to high temperature Aging of internal devices and cabinets. Four letter intelligent dehumidification device changed the passive anti-condensation method to actively guide condensate, effectively preventing hidden safety hazards such as equipment aging, reduced insulation strength, secondary terminal breakdown, material mildew and corrosion of steel structural parts in the cabinet, to ensure Safe operation of equipment in the cabinet.
Software platform features
parameter settings
Temperature alarm threshold: When the
temperature in the ring network cabinet
exceeds the set threshold, remind the
staff.
Humidity alarm threshold: When the
humidity exceeds the set threshold,
remind the staff. When the humidity
reaches the starting value of the
dehumidifier, the dehumidifier starts and
the humidity decreases.
Humidity hysteresis: when the humidity
drops to a certain range, the
dehumidifier stops dehumidification.

Alarm message sending
When the dehumidification device detects that the temperature or humidity
in the cabinet is too high, it will actively send information to the main station,
and the public account will push related alarm information. The information
content includes: alarm time, address or cabinet number of the
corresponding ring main unit, and specific events .
|
Equipment management
You can check the working status and online status of the hardware device
through the background, and perform maintenance operations such as
adding, modifying, and deleting device information.
