Consequences of dry type transformer instability

Release time:2020-11-04 09:39:35 Popularity: Source:未知

    Users of power equipment know that dry-type transformers have their own currents and voltages, which should generally be safe and stable.

  Sometimes, when the dry type transformer work and operation is intense, should consider whether the voltage of the dry type transformer stable. If unstable, they will cause a huge failure of the dry-type transformer and lead to an explosion of the dry-type transformer, which is even more dangerous and has unimaginable consequences. Therefore, the consequences of voltage instability of dry type transformer are relatively large. Today we will introduce the consequences of transformer instability.

 Since the dry type transformer plays such an important role, what serious consequences will it have if the voltage is unstable? In fact, it mainly has the following two effects:

 
 
 
1. When the voltage of dry-type transformer is unstable, an unbalanced current several times higher than the normal current will occur. The temperature of some metal parts of the equipment will rise sharply, resulting in a short circuit and the dry-type transformer may be directly burnt out. It increases the cost of maintaining electrical equipment and shortens its service life.
 
 
 
2. In production and life, the unstable voltage of the dry transformer makes the three single regulators operate asymmetrically, resulting in the increase of the dry transformer losses (no-load losses and load losses).

  It has a serious effect on line loss. Dry transformers have unstable voltage and unstable current. At this point, no matter how the current is distributed to a single dry transformer, the unbalanced current distribution will be unbalanced. The greater the unbalanced current is, the more serious the line loss will be.
