Abstract:
     This equipment consists of several independent blowout plates, which are located near the blowout contact and lead the heat air flow caused by the electric arc generated by the on-off of the circuit breaker contact; a pair of side parts used to hold these blowout plates; and a steering convax piece located closely near the inner side of the side parts. There is a distance between each of the convax part and the end of the plate towards the contact, and this convax part convaxes opposite to the direction of the side parts, so that it may resist the heat flowing to the inner side of the side parts.
