6 Frequently Asked Questions about “Special contactor for compensation capacitor”
What type of contactor is used for capacitor switching?
Contactors for Capacitor Switching(UA 16 to UA 110) Maximum permissible peak current Î< 100 times the nominal rms current of the switched capacitor. A... and AF... Standard Contactors(A 12 to A 300 and AF 50 to AF 750) Maximum permissible peak current Î < 30 times the nominal rms current of the switched capacitor. Contactors for Capacitor Switching
Which contactors are suited for capacitor bank switching?
Application The A...and AF...contactors are suited for capacitor bank switching for the peak current and power values in the table below. The capacitors must be discharged (maximum residual voltage at terminals < 50 V)before being re-energized when the contactors are making.
What is a capacitor compensation cabinet?
Generally speaking, capacitor compensation cabinets are installed in the power distribution room to improve the power factor. The contactor that controls the on and off of the capacitor is called the capacitor switching contactor, which is similar to the conventional contactor. However, there are some difference between them.
What is a capacitor contactor with a damping resistor?
Capacitor contactors with damping resistors make use of pre-switching auxiliary contacts. They close before the main contacts and pre-load the capacitor thus avoiding current peak values. This positively influences the life expectancy of the capacitor and the positive impact on the power quality. The values above reflect typical specifications.
What type of contactors can be used on multi-step capacitor bank?
The use of standard A 9 ... A 110 3-pole contactors is then possible on multi-step capacitor bank. The capacitors must be discharged (maximum residual voltage at terminals < 50 V)before being re-energized when the contactors are making. In these conditions, electrical durability of contactors is larger than 100 000 operating cycles. Selection Table
What is the main function of a capacitor contactor?
The main function of the capacitor contactor lies in the auxiliary contact, which is very different from the conventional contact. The 33 and 34 contacts on the auxiliary contacts of the capacitor contactor have the same function as the conventional auxiliary contacts, which act together with the main contacts of the contactor.
