In China's power transmission and distribution engineering, a kind of three post horizontal rotation type double break mouth isolating switches have been extensive use of, this three post horizontal rotation type double break mouth isolating switches are on the porcelain vase top of both sides the fixed contact assembling to be installed, the conducting rod that horizontally rotates is installed on the porcelain vase of centre, and the two ends of conducting rod are separately installed with the moving contact with both sides fixed contact assembling corresponding matching.This fixed contact assembling comprises the stationary contact headstock, one side of stationary contact headstock offers the U-lag mouth, mode is separately installed with the U-shaped static contact finger axisymmetricly on the upper and lower cell wall of U-lag mouth, the opening of two U-shaped static contact fingers all towards the bottom land of U-lag, is connected with the spring that is used to clamp moving contact on the U-shaped static contact finger.During combined floodgate, conducting rod drives moving contact and horizontally rotates, and produces axially rotation when the contact fixed contact, and the spring that relies on compression to link to each other with static contact finger provides contact pressure.But adopt this structure, it is when conducting rod rotation is ordered about moving contact and contacted with fixed contact, because the opening direction of two U-shaped static contact fingers on the stationary contact headstock is identical, a feasible side U-shaped static contact finger opening direction and a moving contact direction of rotation wherein, thereby can produce bigger frictional force between the dynamic and static contact, not only influence the cooperation of dynamic/static contact, and can strengthen the load of operating mechanism, reduce the reliability of isolating switch; Simultaneously, in this isolating switch, owing between moving contact and the fixed contact buffer unit is not set, its moving contact in the process of closing a floodgate can produce bigger impact to fixed contact, destroys the stability of isolating switch.
The utility model content
The purpose of this utility model is: a kind of high voltage isolation switch contact assembly is provided, has the problem of big frictional force when solving in the prior art divide-shut brake between the moving contact and fixed contact.
The technical scheme of the utility model high voltage isolation switch contact assembly is: a kind of high voltage isolation switch contact assembly, comprise moving contact and fixed contact, described moving contact comprises that the T shape movable contact that is used for radially being fixed on relative both sides, conducting rod end refers to, T shape movable contact refers to be symmetrical arranged along the axis of conducting rod, described fixed contact comprises the stationary contact headstock, side at the stationary contact headstock offers the U-lag mouth, be respectively arranged with the U-shaped static contact finger that cooperates with corresponding T shape movable contact abutment on the cell wall of the both sides up and down of U-lag mouth, the opening direction of described two U-shaped static contact fingers is the tangential direction when corresponding T shape movable contact refers to rotate respectively.
Described U-shaped static contact finger is made up of the U-shaped static contact of arranging side by side more than two.
Be provided with elastic buffering mechanism at the bottom land of the U-lag mouth of described stationary contact headstock towards the notch direction, mainly by being fixed on shell on the stationary contact headstock, axially being installed in the compression spring in the shell and cooperate with the shell axial limiting and form with the push rod that join on compression spring top, push rod is towards the U-lag mouth direction horizontal-extending of stationary contact headstock for this elastic buffering mechanism.
On the cell wall of the both sides up and down of described U-lag mouth, be respectively arranged with the top pressure spring that corresponding roof pressure with each described U-shaped static contact cooperates.
One end outer wall of described each stationary contact headstock is provided with the auxiliary fixed contact that is used for striking, and an end that refers at T shape movable contact is coaxial to be equipped with auxiliary moving contact with auxiliary fixed contact corresponding matching.
Contact assembly of the present utility model is simple in structure, dependable performance, installation and maintenance convenient, because it has adopted the opening direction with the U-shaped static contact finger to be made as the tangential direction of T shape movable contact spindle when rotating, thereby can reduce the moving contact frictional force in when upset, solved in the prior art between the dynamic and static contact the bigger problem of frictional force when divide-shut brake, thereby reduced the load of operating mechanism, improved the reliability that dynamic/static contact cooperates.
