Abstract
The invention relates to a long-break-distance contact structure capable of breaking rapidly. The long-break-distance contact structure mainly solves the technical problem that when breaking is performed on an existing contact structure, due to limit of an operation mechanism structure, the breaking capacity of the contact structure is affected. The contact structure comprises a base, an operation mechanism, a moving contact and a fixed contact. A supporting part is installed on the base, the fixed contact and the moving contact can both rotate by a certain angle, a rotating part is connected with the fixed contact through a transmission part, and the rotating part rotates to drive the fixed contact synchronously through the transmission part to rotate in the rotating direction opposite to the moving contact so as to form mutual joint or separation. Due to the fact that the structure distribution mode that the moving contact and the fixed contact move simultaneously is adopted in the contact structure, during opening, the moving contact and the fixed contact rotate in the opposite directions at the same time, the breaking speed between the moving contact and the fixed contact is improved, the maximum contact break distance between the moving contact and the fixed contact can be increased, and therefore the breaking speed of the contact structure is effectively improved. The long-break-distance contact structure has the advantages of being simple in structure, high in reliability and rapid in breaking speed.

Described driving member is connecting rod, and one end of described connecting rod is hinged by the first jointed shaft and rotating part, and the other end of described connecting rod is hinged by the second jointed shaft and fixed contact.
Breaking speed between described moving contact and fixed contact equals moving contact movement velocity and fixed contact movement velocity sum.
Under gate-dividing state, moving contact move distance and fixed contact move distance sum when the most large opening between moving contact, fixed contact equals separating brake.

Embodiment
For accompanying drawing, embodiments of the invention are described further below:
As shown in the figure, a kind of can the large opening structure of contact terminal of disjunction fast, comprise pedestal 14, operating mechanism 7, moving contact 6, fixed contact 3 and rotating part 8, described moving contact 6 is installed on rotating part 8, described operating mechanism 7 matches with rotating part 8 and drives moving contact 6 to rotate to an angle, described pedestal 14 is provided with terminal block 1, be flexible coupling 2, described fixed contact 3 by be flexible coupling 2 with terminal block 1 integrally welded, described pedestal 14 is provided with supporter 13, described fixed contact 3 is articulated with on supporter 13 by axle 12, supporter is fixed by screws on pedestal, what described fixed contact 3 can rotate to an angle is installed on supporter 13, described rotating part 8 is connected by driving member 10 with between fixed contact 3, described rotating part 8 is rotated through driving member 10 Timing Belt dynamic/static contact 3 and rotates towards the direction of rotation contrary with moving contact 6 and form bonded to each other or be separated.Here driving member 10 is connecting rod, one end of described connecting rod is hinged with rotating part 8 by the first jointed shaft 9, the other end of described connecting rod is hinged with fixed contact 3 by the second jointed shaft 11, connecting rod two ends are linked together with moving contact 6, fixed contact 3 respectively by the first jointed shaft 9 and the second jointed shaft 11, form linkage.During use, circuit breaker by separating brake to closing operation time, operating mechanism 7 drives rotating part 8 to rotate, rotating part 8 drives moving contact 6 to rotate toward combined floodgate direction, and rotated toward combined floodgate direction by connecting rod band dynamic/static contact 3, dynamic and static contact rotates simultaneously, finally reaches the effect of breaker closing.Circuit breaker by close a floodgate sub-switching operation time, operating mechanism 7 drives rotating part 8 to rotate, and rotating part 8 drives moving contact 6 to rotate, and is rotated by connecting rod band dynamic/static contact 3, dynamic and static contact is rotated toward contrary direction simultaneously, makes breaker open operation.
In the present invention, circuit breaker is when sub-switching operation, breaking speed between described moving contact 6 and fixed contact 3 equals moving contact 6 movement velocity and fixed contact 3 movement velocity sum, under gate-dividing state, moving contact 6 move distance and fixed contact 3 move distance sum when the most large opening between moving contact 6, fixed contact 3 equals separating brake.Because moving contact and fixed contact adopt the mode of being synchronized with the movement to realize disjunction, therefore, the speed of contact disjunction is moving contact 6 movement velocity and fixed contact 3 movement velocity sum, significantly shortens the time of disjunction, effective raising disjunction efficiency.
