Abstract
The utility model discloses a disconnecting switch structure including a switch housing. An electrical chamber and a mechanism chamber are disposed in the switch housing. Two sides of the electrical chamber are provided with three pairs of mutually opposite incoming and outgoing lines. An insulator and a vacuum extinction chamber connected to the outgoing lines are disposed in the electrical chamber. The incoming lines are at the same horizontal height with the insulator. The outgoing lines are disposed below the insulator. A sliding contact member is hinged and installed onto the insulator. In the disconnecting switch structure, the distance between the incoming and outgoing lines are carefully handled in the electrical chamber of the switch housing, so that when the incoming lines are at the same horizontal height with the insulator, the outgoing lines are disposed below the horizontal position. In this way, the distance between the incoming and outgoing lines in the limited space is effectively expanded, so when the filling of inert gas is not needed, spark interference between the incoming and outgoing lines can be avoided, the safety of the disconnecting switch is guaranteed and the pollution of the environment is also avoided. The disconnecting switch structure is used in the field of electrical switches.
