Abstract
The utility model provides a vacuum switch tube for a 12-kilovolt guide sleeve anti-torsion type circuit breaker, which comprises a porcelain tube. The axis positions of the two ends of the porcelain tube are provided with a movable conducting bar and a static conducting bar. The end of the movable conducting bar is provided with a movable contact. The end of the static conducting bar is provided with a static contact. The static contact and the movable contact are in contact with each other. A protective cover is arranged between the movable contact and the movable conducting bar. The upper end of the movable conducting bar is sequentially sleeved with a guide sleeve and a movable end cover. The movable end cover is fixed at one end of the porcelain tube. A bellows is arranged between the movable end cover and the protective cover. The bellows is sleeved onto the movable conducting bar. The movable contact, the static contact and the static conducting bar are positioned in a screening drum. The outer surface of the porcelain tube adopts a plane smooth type structure. The guide sleeve adopts an anti-torsion structure provided with a keyway. The guide sleeve of the vacuum switch tube can be better matched with the movable conducting bar in size so as to realize the anti-torsion effect. Thus, the anti-torsion moment of the vacuum switch tube can be up to more than 50 N*M, so that the switching reliability is improved. Meanwhile, the service life of the vacuum switch tube is prolonged, thereby greatly satisfying the requirements of a user.
