1、 Product Overview

The intelligent dehumidification device adopts the semiconductor refrigeration dehumidification method, actively sucking the humid air in the enclosed space into the dehumidification duct under the action of the fan. The water vapor in the air is condensed into water after passing through the semiconductor refrigeration mechanism, and then discharged from the cabinet through the water conduit, which can achieve a good dehumidification effect. By reducing the moisture content in the air, both relative and absolute humidity can be lowered simultaneously, with almost no increase in temperature or negative effects caused by temperature differences. This fundamentally eliminates or reduces the occurrence of accidents, and does not accelerate the aging of cabinet components and cabinets due to high temperatures. The intelligent dehumidification device replaces the passive prevention of condensation with active guidance of condensation, effectively preventing safety hazards such as equipment aging, reduced insulation strength, secondary terminal breakdown, material mold, and steel structure corrosion inside the cabinet, ensuring the safe operation of the power grid.

Condensation inside the equipment can cause creepage and flashover accidents, which generally occur in the following situations:

The humidity in the area is high, the weather temperature changes greatly, the bottom of the switchgear is moist, and some cable trenches even have accumulated water;

Some switchgear is located in the basement with high humidity, and the temperature inside the cabinet, especially near the ground, is lower than the ambient temperature;

Some equipment is temporarily shut down, and the temperature inside the electrical cabinet is lower than the surrounding environment, making it easy for condensation to form on its surface. In this case, once the power is put into operation, accidents will occur. In order to ensure the safe operation of the power grid system and the long service life, safe and effective use of electrical equipment, the power system has put forward higher requirements for moisture-proof and anti condensation inside the cabinet.

2、 Main functions

▲ Small size, light weight, easy and fast installation;

▲ Switching between automatic and manual dehumidification functions, adjustable temperature and dehumidification start values;

The dehumidification duct actively introduces condensation and exhausts gas for heating and dehumidification, effectively achieving comprehensive treatment of moisture-proof and dehumidification in enclosed spaces of electrical cabinets;

▲ Humidity and temperature sensors take real-time samples 24 hours a day, and automatically trigger condensation when exceeding the set starting value;

▲ The humidity and temperature settings have a memory function and will not disappear when the device is turned off;

▲ Fault display function, which can quickly locate the fault point to ensure normal operation;

▲ Using specialized moisture-proof components, the shell adopts an aluminum alloy structure to ensure normal operation in humid environments;

The application of shielding and isolation technology complies with the Level 3 standard of GB/T17626-2008, ensuring that it can operate under strong electromagnetic fields;

The dehumidification and condensation pipeline can discharge the condensed water outside the cabinet, and can also be collected outside the storage bag cabinet.
