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 an arc extinguishing switch for a ring main unit. The arc extinguishing switch comprises a shell, a deflector rod and a switch body, the deflector rod is slidably connected to the shell and extends out of the shell, the switch body is installed in the shell, the switch body comprises an installation pipe, the installation pipe is fixed in the shell, the installation pipe is a pipe body with openings in the two ends, and a piston connecting column is slidably connected in the installation pipe; the piston connecting column is in clearance fit with the installation pipe, piston driving rods are slidably connected to the two ends of the installation pipe, and the other ends of the piston driving rods extend out of the installation pipe; the deflector rod is shifted to one end, extending out of the installation pipe, of each piston driving rod; a first contact is arranged on the installation pipe, the first contact is flush with the inner wall of the installation pipe, a second contact is arranged on the piston connecting column, and when the piston connecting column slides to one end of the installation pipe, the second contact is in contact conduction with the first contact; and the installation pipe and the piston connecting column are both made of ceramic materials, and sealing rings are arranged on the periphery of the piston connecting column and the periphery of the piston driving rods.
Description
technical field [0001] The invention relates to the field of power transmission and transformation, and more specifically relates to an arc-extinguishing switch for a ring network cabinet. Background technique [0002] The ring network cabinet is a set of high-voltage switchgear installed in a steel plate metal cabinet or made into an assembled interval ring network power supply unit. It has the advantages of simple structure, small size, low price, improved power supply parameters and performance, and power supply safety. . Among them, the load switch will generate arc sparks during the opening and closing process. In order to prevent the arc from causing damage to peripheral components, and to prevent the sparks from generating heat and melting or burning the switch contacts when the switch is closed, it is necessary to perform arc extinguishing treatment on the high-voltage circuit switch. . [0003] The most commonly used arc extinguishing device is a vacuum interrupte...
