3300kVA Excitation Transformer 18kv 0.85kv Cast Coil Dry Type Transformer

The excitation transformer is a specifically for the excitation system of a generator to provide three-phase AC excitation power supply device, excitation system through the silicon controlled rectifier, the three-phase power conversion for generator rotor DC power supply, the formation of the generator field, through the excitation system, regulating thyristor trigger angle, to achieve the purpose of regulating the motor terminal voltage and reactive power.

 

Usually connected to the outlet end of the generator,the ouput voltage of the generator is high, and the rated voltge of the excitation system is relatively low,so it is necessary to take a step down transformer. Generator excitation transformer of the safe and stable operation is self and shunt unit safe and stable operation of the premise,turbine power generator stability,full load power generation of prerequisites,is key to the reliable operation of the excitation system.

    DESCRIPTION

    Excitation Transformers are used to excite the field of generators through a rectifier. They are designed to handle,non-linear, non sinusoidal loads resulting from their use with a variety of power electronic applications such as diode, thyristor or motor drive configurations from 6, 12, 24, 36, 48, or 60 pulse configurations.


    Products according to the structure for open type and door type two kinds,the door is uses the steel plate is processed into a box sheel, transformer inside the box shell,the shell outside the box a pass in and out line hole to install power lines.When necessary, according to the user's request to increase the voltage meter, current meter, temperature control alarm system,steering wheel,etc.in order to move.
