The alignment of the three contact bars 42 with respect to the longitudinal axis of the fixed contact device 16 The center is operated by being disposed on the back of the contact bar 42 and snapped onto the edge 46 of the center shoulder 48 of the stud 24.

Description of the invention (printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, fragment 58 is made of steel Or ferromagnetic material is made of copper-zinc alloy welded around the electrode 54 of the main body 52 to perform the arc guide and generate a good magnetic field distribution by the electromagnetic wire 圏 18 when the arc is transferred on the track 32. The axis length of the segment 58 is The action of the arc extinguishing chamber 10 according to the present invention which is larger than the electrode 54 and extends to a cylindrical portion adjacent to the main body 52 is as follows: In the closed position (FIG. 1), the movable contact 14 is inserted into the fixed contact device 16, and It is coupled with the copper body 52 to allow a permanent current to flow, and it can have a rated current of 630A. Since the entire current flows through the stud 24, the contact bar 42, and the movable contact 14 of the tube 20, the contact pressure is the contact bar. A spring 44 above 42 is applied while the coil 18 is disabled. Tightening forces cause compensation effects to be obtained from the contacts to keep them closed. In case of a short-circuit current, the operating mechanism slides the tube 20 upward, so that the movable contact 14 is pulled back in the direction of the electrode 54. An arc is formed immediately when the movable contact 14 is separated from the electrode 54, which is a small axial gap separated from the track 32. The arc moves to the track 32 and then causes the current to flow into the coil 18 and the support arm 34, and the arc is caused to rotate around the track 32 at high speed by the formed magnetic field. Therefore, no current flows through the contact bar 42. The rise in the temperature of the arc causes the pressure of the SF6 gas in the enclosed chamber I2 to increase, and then the gas flows through the tube to a diffusion volume tank (not shown). When the arc is sufficiently cooled by the airflow, the arc disappears immediately (Figure 2). The hybrid operation of the fixed contact device 16 is the main contact and the arc contact 'are located in the internal space of the coil 18, making it possible to obtain a very small arc suppression chamber at a low manufacturing cost.
