2019-10-24

The uses of electronic desiccants. Electronic and electrical equipment includes primary and secondary equipment. Primary equipment mainly refers to equipment that directly generates, transmits, and consumes electrical energy, such as power generation, substations, transmission, distribution, and power consumption. Examples include generators, transformers, overhead lines, switchboards, and switchgear. Secondary equipment refers to equipment that performs control, protection, and measurement functions. Examples include cables, switchboards, motors, switches and sockets, lamps, air conditioners, electric water heaters, and electricity meters. These electrical devices encounter moisture problems during storage, transportation, and use. What methods are available for moisture prevention and dehumidification of electrical equipment?

These electrical devices encounter moisture problems during storage, transportation, and use. What are the methods for moisture prevention and dehumidification of electrical equipment?

Desiccant method

Place calcium chloride desiccant bags in the storage boxes of electrical equipment to absorb moisture in the box, reduce the humidity inside the cabinet, and prevent condensation. This method is simple and easy to use, suitable for situations with seasonally high humidity and no power supply. It is a commonly used moisture-proof product for electrical equipment.

Semiconductor refrigeration dehumidification method

The advantages of the semiconductor refrigeration dehumidification method are low energy consumption, safety, stability, environmental protection, and strong dehumidification capacity. It can absorb water vapor in the cabinet and condense it into liquid for discharge, reducing the relative humidity inside the cabinet and the water content of the air. There is no return of moisture during the dehumidification process, and even after power failure, the humidity rises slowly, and no heat effect is produced.

The dehumidification device can effectively reduce the water content of the air, avoiding problems such as fouling of power equipment, heat effects, condensation, partial discharge, reduced insulation of components, and corrosion of the cabinet, extending the service life of the equipment and ensuring the safe and stable operation of the power equipment.

Electric heating method

Heating-type dehumidification increases the temperature inside the cabinet, only reducing the relative humidity inside the cabinet, but not reducing the water content of the air inside the cabinet. Once the ambient temperature changes significantly, the humid and hot air will quickly condense. It does not solve the problem of condensation inside the electrical cabinet. The dehumidification effect is not obvious, and there are safety hazards.
