Abstract

The utility model relates to a transmission mechanism for an outdoor high-voltage vacuum switch. With utilization of the transmission mechanism, problems that the existing rotating type transmission mechanism with the disadvantages of complex structure, large size, high cost, and low efficiency can not realize the waterproof performance and synchronous periodicity of opening and closing of the three-phase arc extinguish chamber can not be ensured easily can be solved. The transmission mechanism is characterized in that two connecting plates are installed in each of fixed racks; and the fixed racks are connected with the connecting plates and transmission rods by first pin rolls and are connected with the connecting plates and transfer rods by second pin rolls. The other ends of transfer rod support plates are connected with third pin rolls installed at the fixed racks; and the other ends of transmission rod support plates are connected with fourth pin rolls installed at the fixed racks. When the transmission rods are pushed towards the right, the arc extinguish chamber is in an opening state; and when the transmission rods are pulled towards the left, the arc extinguish chamber is in a closing state. And a rainproof cover is installed at the outer sides of the fixed racks. The provided transmission mechanism has the following beneficial effects: the structure is simple; the size is small; the cost is low; the waterproof performance is realized; the efficiency is high; the synchronous periodicity of opening and closing of the three-phase arc extinguish chamber can be ensured; because each of the fixed racks is an independent unit, the interchangeability is good; the standardized production can be realized; and installation, maintenance and replacement can be carried out conveniently.
