Abstract (en)
[origin: CN115172094A] The invention provides an improved vacuum interrupter pole for a circuit breaker and related electrical equipment. The vacuum arc-extinguishing chamber pole comprises a vacuum arc-extinguishing chamber. An insulating support housing for accommodating and supporting the vacuum interrupter and having a top wall and side walls defining a U-shape, the vacuum interrupter adapted to be disposed within an internal space defined by the side walls via an open side of the U-shape; and the conductive connecting piece is provided with a first end and a second end, the first end is fastened between the top wall and the vacuum arc-extinguishing chamber and is electrically connected to the vacuum arc-extinguishing chamber, and the second end is suitable for being used as a supporting point of an isolating switch moving knife component electrically connected with the circuit breaker.
