Product Description

11kv 433v 2500kva scb10 dry type transformer faults can be divided into internal faults and external faults.Internal faults refer to faults occurring inside the tank enclosure, including phase to phase short circuits of windings, inter turn short circuits within a single phase winding, short circuits between the winding and the core, and winding disconnections open circuits.

External faults refer to various phase to phase short circuit faults between the 11kv 433v 2500kva scb10 dry type transformer's external bushings/leads, and single phase ground faults caused by flashover of the bushing insulation through the tank enclosure.

Transformer faults can be very harmful. Especially during an internal fault, the high temperature electric arc generated by the short circuit current will not only burn the winding insulation and the core but also cause the transformer oil to thermally decompose, producing large amounts of gas, which can lead to deformation or even explosion of the transformer tank. Therefore, a transformer must be disconnected tripped when a fault occurs.

Abnormal conditions of transformers mainly include overload, low oil level, overcurrent caused by external short circuits, excessively high oil temperature during operation, excessively high winding temperature, excessive transformer pressure, and cooling system failures. When the transformer is in an abnormal operating state, an alarm signal should be issued.
