Problems solved by technology

In known solutions, adjusting the damping characteristics involves a huge effort and may not be easy to implement
An additional disadvantage is that the switching energy is suppressed in linear motion and thus makes the springback dependent on the material properties

Embodiment Construction

[0022] exist figure 1 A switching device 1 is shown in FIG. 1 with a housing 2 consisting of a housing lower part 3 on which a housing upper part 4 is mounted. The housing lower part 3 is designed as a magnetic chamber 5 which has a magnetic chamber floor 6 on its bottom side. Arranged in the magnetic chamber 5 is a drive unit 7 consisting of a yoke 8 placed on the magnetic chamber base 6 , a coil 9 arranged on the yoke 8 and an armature 10 movably arranged on the coil 9 .

[0023] figure 2 shows a switching device 1 with a magnetic damping structure 11 and a magnetic cavity floor 6 , on which the elevation is designed as a fastening bracket 12 on the one hand and introduced into a recess 13 on the other hand. The groove 13 has a defined distance measured from the fixed bracket 12 and is used for inserting the damping element 14 . Depending on the required damping force, the damping element 14 is inserted into the recess 13 provided for it and can thus be adjusted. Arrang...

Abstract

The invention relates to a switchgear (1), particularly a protection, comprising an upper housing part (4) and a lower housing part (3), a magnet chamber (5) disposed in the lower housing part (3), in which a drive unit (7) made of an armature (10), a coil (9), a yoke (8) and a magnetic damping arrangement (11) for damping the yoke (8) are all disposed. The invention is characterized in that the yoke (8) for damping is disposed on both a fixed bearing (12) and on a damping element (14).

Description

technical field [0001] The invention relates to a switching device, in particular a contactor, having a housing upper part and a housing lower part, a magnetic chamber arranged in the housing lower part, in which an armature, a coil, a yoke and A drive unit composed of a magnetic damping structure for damping the yoke. Background technique [0002] Switching devices with AC-drive units have a very high connection speed when the magnetic system is closed. At the same time, the armature with the contact carrier hits the yoke and bumps the moving contact bridge from the disconnected position to the connected position on the fixed contacts. Owing to the high impact speed, the armature with the contact carrier and its moving contact bridge can spring back into the open position again, which is referred to as "contact vibration". In this case, an arc is formed between the moving contact and the stationary contact, which has a negative effect on the mechanical and electrical serv...
