Cooling method for dry-type transformers
1. Open type: It is a common method where the body of the device comes into direct contact with the air and is integrated into a relatively dry and clean room. (When the working temperature is 20 degrees Celsius, the air humidity should not exceed 85%.) Generally, there are two cooling methods: gas over temperature protection and air cooling.
2. Closed type: The device is placed inside a closed casing and does not come into direct contact with air (suitable for mines due to its sealing and heat removal standard deviation, classified as explosion-proof).
3. Pouring type: Using epoxy resin adhesive or other epoxy resin pouring as the main insulation layer, it has a simple structure, small size, and is suitable for small volume dry type transformers.
Characteristics:
1. Safety, fire safety, zero pollution, can immediately operate on the load core;
2. Select excellent Chinese technology, high impact toughness, strong ability to withstand short circuit faults, small local discharge, good heat resistance, high stability, and long service life;
3. No consumption, low noise, environmental protection and energy saving, with significant practical effects and maintenance free;
4. Good heat removal characteristics, strong overload working ability, and can increase volume operation when forced to be water-cooled;
5. Good waterproof function, integrated into high environmental humidity and other extreme environments for operation;
6. Dry test dry-type transformers can be equipped with sound temperature measurement and maintenance system software. Using intelligent data signal temperature control system software, it can automatically identify and tour to indicate the operating temperature of the three-phase winding resistance, automatically start and stop the centrifugal fan, and have functions such as alarm and power outage settings;
7. Small size, light weight, less indoor space, and low installation cost.
