Product Description

Product overview:

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.

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.

Product features:

The new high-quality silicon steel sheet production,reduce loss,improve efficiency.
Using high temperature and high quality wire to make,its own loss to the minimum,greatly improve the
effectiveness of.
Using high temperature resistant insulation material,improve the resistance to high pressure strength,insulation
level,prolong service life.
Patent design,beautiful,innovative,high power density,small size,high space usage.
