Embodiment Construction

[0021] figure 1 A perspective view showing an embodiment of the short circuiter 1 of the present invention. The illustrated short circuiter 1 has a vacuum switching tube 2, in which a vacuum switching chamber not shown in the figure is designed to be evacuated. In the vacuum switching chamber of the vacuum switching tube 2 , a fixed contact (not shown) and a moving contact, which are fixedly connected to the vacuum switching tube 2 , face each other in the longitudinal direction 3 . The moving contact is guided in longitudinal 3 movement so that by the incoming drive movement, in this case a stroke movement, the moving contact is pressed against the fixed contact so that current can flow through the vacuum interrupter 2.

[0022] In order to movably fix the moving contact while maintaining the vacuum inside the vacuum switch chamber, a metal bellows box 4 is provided. The metal bellows box 4 is fixed vacuum-tight on the moving contact pin which carries said moving contact o...

Abstract

In order to provide a short-circuit device (1) for the electrical bypass of an electric module having a contact arrangement, which is disposed in a switching chamber, and which has an open circuit-breaker setting, in which a current flow via the contact arrangement is interrupted, and a contact setting, in which a current flow via the contact arrangement is made possible, and having a pyrotechnic drive (10) for transferring the contact arrangement from its circuit breaker setting into its contact setting, using which a cost-effective, rapid bypass or short-circuit is made possible, wherein a large current carrying capacity is provided simultaneously, it is proposed that the switching chamber is a vacuum switching chamber (2), in which a vacuum prevails.

Description

technical field [0001] The invention relates to a short-circuit device for conductively bridging electrical components, comprising a contact device arranged in a switching chamber, the contact device having an open disconnection position and a contact position, in which the current is interrupted by the contact device , current can flow through the contact device when in the contact position; and a pyrotechnic actuator is included for converting the contact device from its open position to its contact position. [0002] The invention also relates to a device for current commutation in the field of electric energy transmission and distribution, comprising a number of high-power semiconductor components connected to each other by electrical connection means to form a series circuit, wherein for each high-power semiconductor component A short-circuit device across the respective high-power semiconductor components. Background technique [0003] Such a crowbar is known from DE1...
