TCD Series Thyristor Switches
The TCD Thyristor Switch is designed for fast switching of parallel power capacitor banks. Based on high-power anti-parallel thyristor technology, it enables inrush-current-free switching with stable and reliable operation. It is suitable for dynamic reactive power compensation applications requiring frequent and rapid switching.
Product Description
The TCD series uses zero-crossing switching technology, triggering thyristors at voltage zero-crossing and turning off at current zero-crossing to achieve inrush-free and arc-free operation. With independent phase triggering and built-in protection functions, it ensures reliable performance in dynamic compensation systems.
Product Features
01
Flexible Compensation Application
Supports three-phase and split-phase compensation systems.
02
Independent Phase Triggering
Provides independent phase control with strong anti-interference capability.
03
Zero-Crossing Switching
Zero-crossing turn-on eliminates inrush current, while zero-crossing turn-off enables arc-free switching.
04
Built-In Protection
Provides transient overvoltage and temperature protection for reliable operation.
