せることができない。Switches such as circuit breakers and disconnectors of the type described above generally have three cylindrical poles arranged in a row on the chassis. In this case, the axial distance between the poles is determined by the dielectric strength of the surrounding medium. The three poles operate simultaneously on the rods that combine the contact rods of each pole and are operated by an operating mechanism common to the three poles. In this known device, the pole support shaft is
The casing of each pole is connected to form a closed box containing the operating rod. In this case, the operating rod penetrates the wall of the box in a sealed manner and cooperates with an operating mechanism provided outside the box. This known unit has a large volume, is complicated, and cannot be adapted to the usage conditions (for example, improvement of the axial distance between the poles).

云う利点がある。The function of this mechanism is the same as the previous application. When the operating mechanism 68 opens or closes the shaft 28, the shaft 28 rotates in either direction. This rotation is 3
It is transmitted to the contact rod 26 of one pole 10, 12, 14. The force is transmitted from the piece 30 via the boss 42 of the crank 24 to the piece 32. In this case, the resistance must of course be constant. Between the pieces 32, 34, the force is likewise transmitted via the boss of the crank 24 of the pole 12. The connection between the pieces 30, 32, 34 and the boss 42 may be accomplished in a variety of ways (eg, keyed).
The spline connection described above has the advantage that the stress is evenly distributed.

とができる。The unit constitutes a module system in which standard elements can be used, in particular for shaft fragments 32,34 and box fragments 46,48. When making a four-pole disconnector, one need only add one pole to the opposite side of the crank 38. This added pole is adjacent to the pole through the shaft and box fragments similar to fragments 34 and 48 extending between the axes of poles 12,14; 10,12.
Combine with 14. The axial distance of each pole can be increased or decreased by using shaft and box fragments of different lengths. The rotational movement of the shaft 28 maintains the rigid connection of the poles while significantly reducing the volume of the box. The module system according to the present invention can be easily assembled even in the field. In this case, the poles are installed in the factory, fixed to the beam 16, the rod pieces 32,34 and the box pieces 46,48 are joined by fitting the rod pieces to the boss 42 and connecting the box pieces 46,48 to the ring. Perform on site by joining at 50.
The operation mechanism 68 can be replaced with another mechanism according to a user's request.
