Embodiment Construction

[0044] exist figure 1A trigger unit 1 for activating an electrical switching device is shown in FIG. 2 , which is constructed according to the construction principle according to the invention. The flip-flop unit 1 has four different flip-flops 2 , 3 , 4 , 5 . Furthermore, the flip-flop unit 1 has four interfaces 2 a , 3 a , 4 a , 5 a which are designed to receive an electrical input signal 6 , in particular in the form of a signal current 10 , for each flip-flop 2 , 3 , 4 , 5 . Furthermore, the trigger unit 1 has a common interface 7 for connection to a trigger element. The common interface 7 is designed to transmit a uniform electrical output signal 8 to subsequent triggering elements. Each flip-flop 2 , 3 , 4 , 5 has electronics 9 for converting the corresponding electrical input signal 6 into a unified electrical output signal 8 .

[0045] A trigger unit 1 configured in this way enables a simple, cost-effective and space-saving triggering of the electrical switching dev...

Description

technical field [0001] The invention relates to an activating unit for activating an igniting element of an electrical switching device and to an electrical switching device. Background technique [0002] Electrical switching devices, such as power switches, have the task of decoupling and decoupling a certain number of electrical consumers from the power supply network in the event of certain disturbances. Typical disturbances are the occurrence of short-circuit currents, and power switches are conventionally designed to displace switching elements in the event of such short-circuit currents and thus decouple and decouple the connection between consumers and the supply network. [0003] In addition, however, such a decoupling of load and supply network is also undesirable in other cases. In particular, it is possible for the power supply network to be disconnected from the consumers in the event of an undervoltage in the power supply network. To provide functionality for ...
