technical equipment, in particular to switching devices. Lel of the invention increases the mechanical life of the switch by reducing the mass of the main movable contact and simplifying it. After issuing the shutdown command, the main moving contact 1 moves until the main circuit of the current circuit is opened and the current is transferred to the separator circuit. Auxiliary movable contact 5 by pressing the socket 7 is held on the main movable contact 2 of the separator, moves with it along the guide 8, compressing the spring 1 1 until it stops 9 and stops. Upon further movement, contact 2 opens with contact 5, which, under the action of spring 11, returns to its original position. 2 Il.

The invention relates to electrical engineering, in particular to high-voltage generator switches for high rated currents with an increased switching and mechanical resource.

The purpose of the invention is to increase the mechanical resource and reliability by reducing the mass of the main iodomotor contact switch.

FIG. 1 shows the contact system of a high-voltage generator switch; in fig. 2 - the same, in the disabled position. 15

A high-voltage generator switch contains a main moving contact 1 with a separator consisting of a main moving contact 2 located on. one non-movable rosette contact 3 with one axis, inside which, on the basis of the fixed contact of the separator 4, there is an auxiliary movable contact 5 made in the form of a cylinder 6 25 with a socket 7, a guide 8 with an emphasis 9 and a groove 10 for installing a return spring 11. The auxiliary movable contact 5 can be moved with the guide 8 until it stops 9. 30. The socket 7 of the auxiliary movable contact 5 is connected to the main movable contact 2, and the cylinder 6 is connected to a fixed socket 3.

The switch works as follows 35 times.

After issuing the shutdown command, the main moving contact 1 moves until the main current-carrying circuit is opened and the transfer current is moving.

It is placed in the separator chain. Auxiliary movable contact 5 by pressing the socket 7 is held on the main movable contact 2 of the separator, moves with it along the guide 8, squeezing the spring 11, up to the stop 9 and stops. When further, the most immediate movement of the contact 2 is opened with contact 5, which under the action of the spring 11 quickly returns to its original position.

Claims (1)

Claim A high-voltage generator switch containing a main movable contact with a separator consisting of a main movable contact located on the same axis with a fixed outlet contact, inside which an auxiliary moving contact is installed, made in the form of a cylinder with a socket and a guide with an emphasis, and a return spring different the fact that, in order to increase the mechanical resource and reliability by reducing the mass of the main moving contact of the switch, the auxiliary moving contact is directly on the basis of the fixed contact of the separator with the ability to move along the specified guide until it stops, and the socket of the auxiliary movable contact is connected with the main movable contact of the separator, and the cylinder with the fixed socket of the separator. 1488892 Ο
