Introduction

Transformer capacity is an important indicator of load capacity of power transformers, an accurate assessment of capacity is to ensure the reliable supply of electricity basis. 35kV and below voltage level power transformer capacity Evaluation Guidelines

1 Scope

This standard specifies the 35kV and below the voltage level of power transformer capacity testing conditions, testing programs, assessment processes and assessment method. This standard applies to the assessment of 35kV and below voltage level power transformers (excluding high voltage transformers and other special transformers) whether Meet the standard GB/T 6451, GB/T 10228, GB/T 22072, GB/T 25289, GB/T 25438, GB/T 25446 standard standard The amount of sequence.

For ease of use With the repetition below lists some of the terms and definitions in GB/T 2900.95-2015. 3.1.1 Rated power ratedpower The specified value of apparent power marked on the winding together with the rated voltage of the winding determines its rated current. Note 1. Rewrite GB/T 2900.95-2015, the definition of 2.1.3. Note 2. The two windings of a two-winding transformer have the same rated capacity, so by definition it is the rated capacity of the transformer. 3.1.2 Default capacity assumedratedpower Power transformer capacity to determine the flow of the rated capacity of the default value. Note. The first time you can set the nameplate capacity. ......
