Pneumatic busbar switch device

Abstract

The invention discloses an air-actuated bus opening and closing device. The two sides of a vertical post bus are respectively provided with a short-circuit bus; the lower sides of the vertical post bus and the short-circuit bus are provided with sliding girders; the sliding girder that is right opposite to the vertical post bus is connected with a torque arm by a gemel; the two sides of the torque arm are respectively provided with an opening and closing rod; one end of the opening and closing rod is connected with the sliding girders by the gemel, while the other end is connected with the short-circuit bus by a connector; in addition, the two ends of the torque arm are respectively movably connected with a link rod; the other end of the link rod is movably connected at the middle part ofthe opening and closing rod; meanwhile, the torque arm is also movably connected with a driving device. The air-actuated bus opening and closing device causes both the disconnection and connection ofthe short-circuit bus to be completed by a link rod mechanism and the electrical appliance driving device by connecting the link rod mechanism on the short-circuit bus and connecting the driving device on the link rod mechanism; the link rod mechanism is adopted to drive the short-circuit bus, thus not only having high speed, great strength and good synchronicity, but also improving the safety of operators compared with manpower.

Description

technical field [0001] The invention relates to a pneumatic bus opening and closing device, which belongs to the technical field of short-circuit power failure of aluminum electrolytic cells. Background technique [0002] In the production process of electrolytic aluminum, the aluminum electrolytic cell needs to be stopped for overhaul after a certain number of years. Make the current flowing through the aluminum electrolytic cell directly enter the next aluminum electrolytic cell through the short-circuit bus line, so as to realize the shutdown of the aluminum electrolytic cell. After the overhaul, the aluminum electrolytic cell should transfer the current flowing through the short-circuit bus line to the aluminum electrolytic cell, that is, open the short-circuit bus in the closed state. Due to the high voltage and large current of the aluminum electrolytic cell series, the current conversion method is to manually open or close the short-circuit busbar in the aluminum ele...

AI Technical Summary

Problems solved by technology

Because the current on the busbar of the aluminum electrolytic cell is very large, it takes about 15-20 minutes to use the traditional manual disconnection of the short-circuit busbar or manual closing of the short-circuit busbar, and a large number of electric sparks will be generated while disconnecting. Not only time-consuming, but also easy to cause harm to the human body
