The temperature of dry-type transformers is an important performance of dry-type transformers. Although the temperature of dry-type transformers is constantly changing, the temperature of dry-type transformers is also continuously adjusted. The temperature of common dry-type transformers is mainly The tool and part of the adjustment is the temperature controller of the dry-type transformer. The work of the temperature controller of the dry-type transformer is more complicated and important. So what is the working principle of the temperature controller of a common dry-type transformer? Let's check with the editor of the transformer manufacturer in detail:
The working principle of dry-type transformer thermostat
Dry-type transformer temperature controller is a new generation controller specially designed for the safe operation of dry-type transformers. The controller uses single chip microcomputer technology, uses three platinum thermal resistances embedded in the three-phase windings of the dry-type transformer to detect and display the temperature rise of the transformer windings, and has corresponding alarm and control functions to ensure that the transformer runs in a safe state. Dry-type transformer temperature controller adopts high-performance pt100 sensor, which is a control device to ensure the safe operation of dry-type transformer. The instrument has a new design, compact structure, firm structure, eye-catching and intuitive display, and has more complete system protection, parameter storage and output indication functions.
