Coal Mine Drier Introduction
The coal mine electrical equipment in a high humid environment for a long time, due to damp electrical equipment insulation resistance have fallen sharply, creepage, discharge, single phase grounding, short-circuit accidents, damage to equipment, causing blackouts, pose a threat to safety production.
Aimed at this situation, some mine took place in the equipment quick lime, calcium chloride, silica gel desiccant, etc. But as a result of moisture absorption ability is poor, but also corrosion electrical components such as side effects, and changed frequently, affected the normal operation of equipment.
Mine desiccant overcomes the silica gel, quick lime, such as poor hygroscopicity, short service life (about half a month to replace), and avoid the creepage, discharge, single phase grounding, short circuit accident.
Coal Mine Drier Characteristics
Mine desiccant is white powder, no pollution, no corrosion, directly into the electrical equipment. Moisture absorption ability and moisture absorption radius is big, the scene after the use, improve the insulation level of power supply system, greatly reduced the number of open check repair, reduced the equipment damage, reduce the consumption of materials, accessories, benefit is remarkable, has the very good application value.
Use a method according to the size of the electrical equipment capacity, directly put mine desiccant in the electrical equipment within the cavity, and fixed.
