Dry type transformer in a way of doing things also did not break the hold time temperature, however, is that this is a no go up constantly and is slowly, closed in on the dry type transformer, temperature rise is closed to outside doing work, yet there is time dry type transformer temperature rise sharply broke out, make have the instinct of the transformer without broken messy, obstacles to increase is not broken. What is the common reason for the sudden and sharp rise in the temperature of a type transformer in the course of lifting and performing? The barriers to such an outbreak are not a few typical, but have the effect of explosion and fire. What are the causes of the intense rise in the temperature of the dry transformer? The following is simply the cause of the coherent explanation for the master held reference:
(1) the split open and close contact is not good because the pressure of the split open and close contact is not foot or the cross contact is dirty, the cross resistance increases, and the cross point has a fever, especially after the replacement of the split head or when the transformer is overloaded, it is more likely to cause a fever because the split open and close contact is not good.
(2) inter-turn short circuit of the coil inter-turn short circuit to reduce the number of coil turns, and close the outbreak of short circuit circulation, and then the short circuit at the outbreak of high temperature. Severe heavy turn short circuit between the oil temperature rise, short circuit at the oil issued a "purr" sound.
(3) short circuit between silicon steel chips because of external force damage or insulation aging, insulation damage between silicon steel chips, vortex increases, forming part of overheating.
Dry-type transformer instinct and temperature change need to master a high degree of closure, but also to innovate the transformer instinct and obstacles to the processing of planning, the implementation of the utility of the transformer and instinct of tranquility!
