6 FAQs about [Thyristor contactor capacitor]
What is the difference between a contactor and a capacitor?
Each capacitor can be individually fused with an appropriately sized current limit fuse. Conventional switching — Contactor: Contactors are electrically controlled switches for handling higher currents. They are used when the variation in reactive power is slow and the capacitor switching interval is in increments of seconds.
What is a capacitor duty contactor?
Capacitor duty contactors have additional auxiliary contacts with current limiting resistors (pre-charging resistors) in series. The auxiliary contacts come on first, and then the main contacts take over the steady state current of the capacitors.
What is a TSM thyristor switch?
The TSM module series offers fast electronically controlled, self-observing thyristor switches for capacitive loads up to 100 kvar, that are capable of switching PFC capacitors within a few milliseconds nearly without a limitation to the number of switchings during the capacitor life expectancy. The values above reflect typical specifications.
How is thyristor switching simulated?
Auxiliary contact of contactor is monitored for main contact’s switching status – ON/OFF. Two transistor outputs for thyristor switching. The output switching is simulated by increasing and reducing the reactive power (applying constant current and voltage and varying the PF).
How do capacitor banks work?
These capacitor banks are switched on either manually (using circuit breaker or switches) or semi-automatically by a remote-controlled contactor. Automatic power factor correction (APFC): For loads that require varying reactive power, APFC is used. Also, under light load conditions, a fixed capacitor provides a leading power factor.
