Embodiment Construction

[0026] figure 1 The device 1 for actuating a switch disconnector 2 is shown before assembly, wherein the switch disconnector 2 (here in a single-pole design) is fastened to the side of the actuating device 1 . The switch disconnector 2 has main contacts, not shown, which can be opened and closed by means of a switch shaft 3 . The disconnector 2 can be connected to the current circuit to be controlled via the connections 4 , 5 .

[0027] The actuating device 1 is located in a housing 6 , from which the free ends of the drive shaft 7 and the output shaft 8 protrude.

[0028] During assembly, the driven shaft 8 and the switch shaft 3 are connected to each other by being plugged together. For this purpose, a corresponding groove (not shown) is formed in the driven shaft 8 .

[0029] The drive shaft has a square groove 9 into which a corresponding handle can be inserted. Drive shaft 7 from as in figure 1 The open position 0 shown in , the rotation to the closed position I and ...

Abstract

#CMT# # / CMT# The device (1) has main contacts that are opened and closed by an output shaft. A drive shaft (7) is rotatable transverse to the output shaft, where rotation of the drive shaft moves the output shaft from an off position into an on position. A switching state of an auxiliary switch indicates two switching positions in which the output shaft is placed, and an opening of another auxiliary switch is disconnected from the contacts by the output shaft. The output shaft of the former switch and a drive shaft of the latter switch are actuated. #CMT#USE : # / CMT# Operating device for actuating an electrical switch i.e. load circuit breaker. #CMT#ADVANTAGE : # / CMT# The device enables an accurate switching state of the main contacts. #CMT#DESCRIPTION OF DRAWINGS : # / CMT# The drawing shows a perspective view of an operating device and a load circuit breaker before assembly. 1 : Operating device 2 : Circuit breaker 4, 5 : Terminal pieces 6 : Housing 7 : Drive shaft.

Description

technical field [0001] The invention relates to a device for actuating an electric switch having main contacts which are opened and closed by means of a driven shaft, said device having a drive shaft and at least one first and at least one second auxiliary switch, the drive shaft extending perpendicular to the driven shaft and rotatable from an open position to a closed position or vice versa, wherein rotation of the drive shaft drives the driven shaft from an open switch position to a closed switch position Movement or vice versa, at the same time, the switching state of the first auxiliary switch shows which of the two switching positions the slave shaft is at that time, and the opening of the second auxiliary switch at this time, in terms of time, after the main contact is This is done via the driven shaft before disconnection. Background technique [0002] It is known that the load isolating switch is a special structural form of the electric switch. It has contact-lik...
