Thyristor Bypass Switch TBS
TBS, one of the main controlled parts of UPFC, is installed in winding’s terminal of series transformer in valve side in parallel with the mechanical bypass switch. It is able to bypass the series converter quickly and ensure the AC line is not affected in case of converter fault. This also prevents the influence on the converter caused by AC line fault.
Adopting high-power thyristor valves and fast bypass-switch technology with short response time, with high withstand capability of short-term heavy current and high reliability, no needing the parallel of thyristor and the water cooling.
Utilization of high-power thyristor valves and fast bypass-switch technology with short response time, high withstand capability of short-term heavy current and high reliability, no needing the parallel of thyristor and the water cooling.
Adoption of natural cooing for TBS, damping resistance and static equalizing resistance to achieve convenient maintenance and high controllability.
