摘要
The chamber (1) has a tubular shaped arc blast isolating nozzle (5) extending along a longitudinal axis (XX'). A movable contact (3) includes a hollow inner tube (30) whose end is connected to a contact portion (31) of the movable contact, where arc blowing is entirely realized inside of the hollow tube along the longitudinal axis of the chamber. A neck (304) is provided in upstream of the contact portion for passage of gas. A release portion (305) is provided between the neck and the contact portion for passage of gas. An independent claim is also included a high-voltage direct-current conversion substation comprising a thyristor through which opening of a loading valve is realized.
