Problems solved by technology
Although it is small in size and easy to use, due to the need for vacuuming, the production is more cumbersome, and the degree of vacuum during use cannot be guaranteed. If the vacuum interrupter produces small cracks and enters the air, it cannot be judged in time whether it is Reliable and reliable closing operation, which is very easy to cause danger due to the generated arc spark

The invention discloses a universal vacuum arc extinguishing device which comprises a mounting pipe. Two ends of the mounting pipe are open, a piston connecting column and a piston driving rod are arranged in the mounting pipe, and the piston connecting column is a columnar structure and is slidably connected into the mounting pipe to be in clearance fit with the mounting pipe; the piston driving rod is slidably connected into the mounting pipe, and one end of the piston driving rod extends out of one end of the mounting pipe; a first contact penetrates through the inner wall of the mounting pipe in the radial direction, and the first contact is arranged near the middle part of the mounting pipe and is flush with the inner wall of the mounting pipe; a second contact is embedded in the piston connecting column and can make contact with the first contact along with sliding of the piston connecting column, and at least one sealing ring is arranged at the position, located on the mounting pipe, of each of the piston connecting column and the piston driving rod; and the piston connecting column and the piston driving rod are both made of ceramic materials.
Description
Technical field[0001]The present invention relates to the field of high voltage transmission, and more particularly to a universal vacuum arc assembly.Background technique[0002]In high-voltage transmission, the high voltage circuit switch is formed to generate arc sparks, in order to prevent the generating arc from causing damage to the peripheral components, and preventing the shut-off time from generating spark-hot melting or burning switch contacts, it is necessary to arg in high voltage circuit switches. deal with.[0003]The most common arc extinguishing device is a vacuum extinguishing chamber, also known as vacuum switch tube, mainly through the insulation of vacuum in the tube, so that the medium and high voltage circuits avoid arc in the closing power supply process. Although it is compact, it is easy to use, but due to the need for vacuum processing, it is more cumbersome, and the vacuum degree during use cannot be guaranteed. If the vacuum extinguishing chamber produces fin...
