Thyristors form an important component of power systems and are widely used in many industrial applications. TVB300SB-L is a type of thyristor, which is used for power limiting, protection and control in a variety of applications. In this article, we will discuss the application field and working principle of TVB300SB-L.
Application Field of TVB300SB-L
TVB300SB-L is broadly used in power systems for various applications such as distance protection, over-voltage and under-voltage protection, over-current protection and short-circuit protection. It is used for limiting and switching high value or high power currents, typically up to 30,000A.The device is designed to handle power up to 10,000V and is suitable for applications such as induction motor control, variable speed drives, high power switching in traction systems, power switching in furnaces, and transformer or line protection.
Working Principle of TVB300SB-L
TVB300SB-L is an SCR (silicon-controlled-rectifier) device with six independent double-polarity thyristors. The device has four anodes and two cathodes, labelled as A1, A2, A3, A4, K1 and K2. Each of the six thyristors is controlled by four gate control signals RIG, FV, ANO and CATO. The RIG control signal is the control signal for all of the four anodes whereas the FV signal can be used to selectively turn on or off each of the four anodes. The ANO control signal is used to control each of the cathodes and the CATO control signal is used for selective turn on or off of the cathodes.
When the gate control signals are in the desired state, the device is turned on. The device is held on until the voltage between anode and cathode crosses the turn-off voltage. The device then turns off and the current flow through the device stops. This device is also capable of automatically resetting after a short circuit or overcurrent condition.
Conclusion
TVB300SB-L thyristors are widely used in power systems for various applications such as distance protection, over-voltage and under-voltage protection, over-current protection and short-circuit protection. The device is capable of handling power up to 10,000V and current up to 30,000A and is suitable for applications such as induction motor control, variable speed drives, and high power switching in traction systems, power switching in furnaces, and transformer or line protection. The device functions by selectively turning on or off four anodes and two cathodes based on the gate control signals.
