SINGLE PHASE ULTRA LARGE CAPACITY STRONG CURRENT SHORT CIRCUIT TEST TRANSFORMER

摘要

A single phase ultra large capacity strong current short circuit test transformer comprises an upper oil tank (9) and a lower oil tank (8). Two single phase two column type iron cores (17) are disposed in the upper oil tank and the lower oil tank there are totally four iron core main columns and a coil sleeves each iron core main column separately. Two oil conservators (7) are separately located above two sides of the long axis of a transformer main body (1) a connecting line between the centers of the two oil conservators is parallel to the direction of the long axis of the transformer and the two oil conservators are hung on firewalls at the two sides of the long axis of the transformer. Cooling apparatuses (10) are concentrated and arranged at the outside of one side provided with a secondary head end sleeve pipe (4) and a secondary neutral point sleeve pipe (6) of the upper oil tank and the lower oil tank. A primary head end sleeve pipe (2) and a primary neutral point sleeve pipe (3) after being led out from a low voltage lead are connected to an external power grid. Multiple tapping switches (11) are separately located at high voltage and low voltage sides of the transformer main body. The single phase ultra large capacity strong current short circuit test transformer is used for testing and verifying a transformer provided with an anti short circuit capability and providing technical support for developing a safe and reliable high voltage and large capacity power grid and ensuring safe and stable running of the power grid.
