Which unit includes both High Speed Circuit Breaker and Ground Switch?

The High Voltage Container is designed to house various high voltage components, including both the High Speed Circuit Breaker and the Ground Switch. The High Speed Circuit Breaker plays a critical role in protecting the electrical circuits by interrupting the flow of current during fault conditions, while the Ground Switch serves to connect the system to the ground for safety and maintenance purposes.

Including both of these components in the High Voltage Container allows for a compact and efficient design that centralizes high voltage management in traction systems. This not only simplifies the wiring and connections between the components but also enhances safety and operational reliability in high voltage applications.

On the other hand, the other options either do not encompass both elements or are specialized for different functions. For instance, the Traction Container generally focuses on the storage of traction power converters and other associated components but does not integrate these high voltage protective devices. The Static Inverter Unit primarily converts DC to AC power and does not include high voltage circuit protection mechanisms. The Auxiliary Electrical Box typically houses lower voltage components that support various auxiliary functions within the system. Therefore, the inclusion of both a High Speed Circuit Breaker and a Ground Switch makes the High Voltage Container the correct choice in this context.
