TKPL series air bypass switch

The TKPL series air bypass switch is mainly used inside SVG dynamic reactive power compensation devices, installed in parallel with power electronic devices. It is used to quickly isolate faults from the system when an IGBT unit fails, ensuring uninterrupted power supply to the entire line. The product Rated voltage is AC1500V, frequency 50/60Hz. The main Rated currents include 500A, 630A, 800A, and 1000A. The product supports manual tripping and electric closing, and has self-locking functions for both tripping and closing states.
