6 FAQs about [After high-voltage circuit breaker energy storage]

Can a voltage source inverter help a high-voltage DC circuit breaker?

According to the characteristics of voltage source converter-based high-voltage dc (VSC-HVDC) transmission systems, this paper analyzes the shortcomings of existing high-voltage DC circuit breakers, and based on this, proposes a high-voltage DC circuit breaker topology using voltage source inverter to assist current oscillation.

What is the voltage at both ends of a circuit breaker?

At this time, the voltage at both ends of the circuit breaker is the clamp voltage of the arrester 480 kV. The maximum line current during the breaking process is 9.29kA. Fig. 7. Voltage and current waveform when breaking fault current

How many kV can a DC circuit breaker break?

There are already hybrid high-voltage DC circuit breakers and mechanical DC circuit breakers with a rated voltage of 500 kV and a maximum breaking current of 25 kA, and they have been applied in the ± 500 kV Zhangbei four terminal flexible DC transmission system .

What is the clamp voltage of a circuit breaker?

After the arc between the contacts is extinguished, the voltage at both ends of the circuit breaker rises rapidly when the operating voltage of the arrester is reached, the arrester begins to absorb energy. At this time, the voltage at both ends of the circuit breaker is the clamp voltage of the arrester 480 kV.

What is a 10 kV solid-state DC circuit breaker?

In ref. 7,  ± 10 kV solid-state DC circuit breaker based on insulated gate bipolar transistors (IGBTs) in serial connection was developed, a 5.1 kA short circuit current breaking test was carried out, and the dynamic and static equalization voltage of DC circuit breaker components was tested.

What happens if a circuit breaker is out of phase?

recovery voltage (TRV) can still be extremely high. Therefore, the dynamic arc of the circuit breaker is difficult to terminate, and the out-of-phase interruption challenging. The worst for an out‐of‐phase fault is a 180° phase difference between the two systems.
