The utility model content
At heavy current disconnecting switches above shortcomings in the prior art, the purpose of this utility model be to provide a kind of when separating brake, take up room less, and big electric current outdoor disconnector simple in structure.
The technical solution of the utility model: big electric current outdoor disconnector, comprise underframe, operating mechanism, transmission mechanism, insulator, conducting system and earthed switch, described conducting system is made up of static contact mechanism and dynamic contact mechanism, static contact mechanism is arranged on the fixed contact post insulator, dynamic contact mechanism is arranged on the moving contact post insulator, and described fixed contact post insulator and moving contact post insulator all are fixed on the underframe; It is characterized in that described dynamic contact mechanism comprises contact pipe, conductive arm and moving contact terminal block, an end of contact pipe is fixed on the conductive arm, and the fingertip in the other end and the static contact mechanism is connected when closing a floodgate; Described moving contact terminal block is arranged on moving contact post insulator upper end, the rotating interlock plate that is connected with on the moving contact terminal block, and the other end and the conductive arm of interlock plate are rotationally connected; Between conductive arm and moving contact terminal block, also be connected with conductive strips; Lower end at conductive arm is provided with bar-shaped trough, is provided with the lever bearing pin that matches with bar-shaped trough on the interlock plate; Described interlock plate also links to each other with the transmission levers of transmission mechanism, and operating mechanism is by transmission mechanism and the interlock of interlock plate.
Further, described interlock plate is two and is separately positioned on the and arranged on left and right sides of conductive arm, is fixed with the support that is used to install rotating shaft on the moving contact terminal block, and described two blocks of interlock plates all link to each other with the moving contact terminal block by rotating shaft.

With respect to prior art, the utlity model has following beneficial effect:
1, isolating switch of the present utility model takes up room less when separating brake, adopted the separating brake mode that conductive arm is rotated up, thereby reduced behind the switches conductive arm separating brake occupation space in the horizontal direction, particularly, adopt vertical branch brake structure also easier when operation like this because there is a segment distance the common installation site of isolating switch apart from ground.
2, drive mechanism is simple, more convenient to operate, whole linked system only need can realize closing a floodgate and separating brake by the integral body interlock of vertical links, operating lever, operation insulator and operation connecting lever, reduce the number of spare parts of switch inside like this, also reduced the temperature rise many because of part, that the contact causes more.
