Embodiment Construction
[0027] Figures 1a and 1b show an embodiment of a current switch 1 of the liquid metal type, in particular a current limiter or circuit breaker 1 of the liquid metal type, in cross-section and plan view. The current switch 1 comprises solid metal electrodes 2 a , 2 b for connection to a current source 20 and a container 4 of liquid metal 3 . The container 4 has a bottom 6 of insulating material and a cover 6 , between which a dielectric 5 , 8 , 9 and at least one channel 3 a for the liquid metal 3 are arranged.
[0028] According to the invention, the power switch 1 has a dielectric fluid drive 12 with a control device 11, in which the working fluid 9 operates at a predeterminable drive pressure P 1 , P 2 Act directly on a front side surface 3b of the liquid metal 3 and move the liquid metal body 3 from a first position X 1 Move to a second position X 12 , X 2 middle. in the first position X 1 , the liquid metal 3 is at least partly in the operating current I 1 In the fi...
