Dry transformers are widely used in local lighting, high-rise buildings, airports, terminals, CNC machinery and equipment and other places, simply said dry transformers refers to the iron core and winding is not impregnated in insulation oil transformer. So in what case do dry transformers need to do power outage treatment immediately?
1, dry transformer fire, in this case, dry transformer is to be stopped immediately
2, found that the dry transformer sleeve has serious damage and discharge phenomenon, immediately stop the use, and let the professional personnel check
3, dry transformer oil pillow and safety * airway spray oil and smoke
4, dry transformer oil carbon, oil color change is too large, it is necessary to stop checking
5, the dry transformer internal noise is very large and there is explosion, must be immediately disabled to prevent the occurrence of dangerous accidents
6, under the condition of normal load and cold *, the oil temperature of the dry transformer is not normal, and it is still rising
When the dry transformer has these symptoms, it is necessary to immediately outage, if there is no power failure, there will be life danger, and it will damage the dry transformer, and we need to solve it immediately. If you encounter any of the above events, you should be cautious to avoid danger.
