خازن فشار قوی ویشای High Voltage Power Vishay ESTA

خازن های ولتاژ بالا به نوعی خازن اطلاق می شود که از یک بوش سرامیکی، یک گروه عنصر خازن و یک پوشش تشکیل شده است.خازن های ولتاژ بالا دارای ویژگی های کم افت و وزن سبک هستند.
Individual Power Factor Correction
The power factor correction capacitor is connected directly to
the terminals of the consumer and will be switched together
with it. The advantages of this method are: Relief of the
conductor s and switches, no capacitor switches or
discharge resistors are needed, and the installation is simple
and cheap. The individual compensation is the best solution
for large consumers (e.g. motors), particularly if they are
in continuous operation.
Individual Power Factor Correction of 3-Phase Motors
The motor and the capacitor are connected in parallel.
They are both switched in and out by means of one and
the same switchgear and also monitored by a common
protective device. A discharge device is not required, because
discharging takes place through the motor windings.
The switchgear must be rated to be capable of withstanding
the inrush current of the capacitor and the connection s
must be capable of withstanding the full load current of the
motor. The capacitor, in this case, has to be installed in close
proximity to the motor.
