Abstract

The invention relates to a device for performing temperature-rise test on a voltage regulating transformer and a compensating transformer in an 'extra-high-voltage' transformer simultaneously. The device comprises a power generating set, control equipment, a first intermediate transformer, a compensating capacitor and a second intermediate transformer. The device has the advantages that by the aid of the control equipment and the power generating set, temperature-rise test can be performed on the voltage regulating transformer and the compensating transformer simultaneously , boosting consistency of the voltage regulating transformer and the compensating transformer is guaranteed, actual on-site operation state of the voltage regulating transformer is conformed better, and workload, complexity in operation, possibility of unnecessary errors and test cost are lowered.

Description

technical field [0001] The invention relates to a device and method for performing a temperature rise test, in particular to a device for simultaneously performing a temperature rise test on a voltage regulating transformer and a compensating transformer in a "double million" transformer. Background technique [0002] With the vigorous development of the national power industry and the continuous construction of UHV power grids, the status of "double million" transformers in the national power grid is becoming more and more important. "Double million" transformers refer to 1000MVA 1000kV double column structure Autotransformer, "double million" UHV transformer includes main transformer and voltage regulation compensation transformer, voltage regulation compensation transformer is composed of voltage regulation transformer and compensation transformer, assembled in an oil tank, and share a set of cooling system. The temperature rise test is a type test, the purpose of which i...
