Problems solved by technology

In addition, the adjustment of the stroke through the lever mechanism requires a relatively complicated adjustment operation; and for safety reasons, the adjustment operation can only be carried out in a voltage-free working state

Embodiment Construction

[0016] From this figure, which shows a section of a switch module SM, it can be seen that a vacuum interrupter SR has an upwardly extending contact connection KO and a downwardly extending contact connection KU. The moving contact of the vacuum switch tube SR not shown in the figure is directly connected with the switch rod SS; the switch rod SS is driven by a driving device not shown in the figure to control the position of the switch along the switch deflection direction shown by the arrow SA. The on-state and off-state of the vacuum switch tube SR above the rod SS. Furthermore, it can also be seen from the figure that an adjustment pin EB is provided on the lower part of the switch lever SS, and that the two free ends of the adjustment pin EB are respectively provided with a threaded pin GB1, 2. The adjustment pin EB has a hexagonal profile in the middle, so that the pin can be turned with a suitable tool so that the threaded pins GB1, 2 engage in the respective internal th...

Abstract

A vacuum switch tube, has switch rods capable of moving straightly, which are respectively conntrolled by a lever mechanism and a drive adaptor through changes in stroke length independently installed by drive mechanisms, wherein the said changes in stroke length is transmited to the vacuum switch tube through the lever mechanism. The present invention suggest that the changes in stroke length are realized by one piece setting bolts (EB) respectively arranged in the longitudinal axes of the switch rods (SS); the bolts (EB) have a hexagonal profile in the middle, and at their free ends they have threaded bolts (GB1, GB2) with threads running in opposite directions; the bolts (EB) are each releasably connected to the switch rods (SS) and to drive adaptors (AA) of the drive mechanisms.

Description

technical field [0001] The invention relates to a vacuum switch tube. Background technique [0002] Such a vacuum interrupter is known from DE 4133092 A1. In this case, the vacuum interrupters of a vacuum interrupter are each individually equipped with a so-called pole drive unit, so that each moving contact inside the vacuum interrupter is actuated by a coupling link, which is approximately horizontal The driving force is converted into a nearly vertical driving force through a lever mechanism. Combined with the function of a support rod, the two toggle rods are arranged opposite to each other, so that they are approximately in an extended state when the vacuum switching tube is turned on. The contact stroke of the moving contact of the vacuum switch tube can be adjusted by the ring screw, which is located between the toggle rod and the support rod. The above stroke adjustment must be matched to various vacuum switch tubes, so the necessary contact adjustment can only be...
