Transformer design calculation tasks
 
    First, to meet the relevant national standards and the requirements of other relevant standards, but also meet the requirements of the contract, usually transformer contract should include the following technical specifications.
    Change a few device types
    Number of phases, the number of windings, auto, step-up or step-down
    The rated capacity of the transformer
    Rated capacity of each winding three-winding transformer or autotransformer rated capacity, or in different cooling mode.
    Transformer cooling
    The oil from cold; air-cooled oil-immersed; forced oil circulation air-cooled; forced oil circulation water cooling; forced oil-oriented cycle air-cooled; forced oil-oriented loop water cooling.
    Transformer rated voltage regulator
    Rated voltage of high-voltage, medium-voltage or low voltage, load voltage regulation or no excitation voltage and its sub-range tap class. OLTC should indicate the neutral point regulator or line-side regulator.
    The impedance of the voltage value of the transformer.
    Connection symbol.
    Transformer load loss and load loss and no-load current.
Technical Data bushing type current transformer.
    Rated frequency.
The altitude of the installation site.
    The above requirements should be consistent with the standards.
    Special requirements.
    The transformer design task, that is, according to the technical specifications in accordance with the relevant national standards, such as power transformers "and" three-phase oil-immersed power transformers technical parameters and requirements and standards, determine transformer electromagnetic load, geometry and electrical thermal and mechanical performance data to meet the requirements of the user departments. Have a good process, making it simple manufacturing, the price of the product should be cheap. Designers and comprehensive consideration of the above factors, comparative analysis of the multi-program, and select the best solution.
