Embodiment Construction

[0041] figure 1 A partial perspective view of an electrical switching device 100 is shown. The auxiliary disconnecting device 1 is installed in this switching device 100 . The central structural component of the auxiliary disconnecting device 1 according to the invention is the storage element 10 which, in the illustrated state, is in its tensioned position 11 . The storage element 10 is connected to the disconnection element 13 via a link guide. Furthermore, the memory element 10 is controlled via the activation element 14 . When the storage element 10 in its tensioned position 11 is activated by the activation element 14 , the storage element 10 performs a movement 12 running in the clockwise direction. As a result of this measure, the disconnecting element 13 is moved by a linear movement 16 , wherein a downstream switching mechanism (not shown) of the electrical switching device 100 separates the likewise not visible switching contacts of the electrical switching device...

Abstract

Auxiliary disconnecting device for electrical switching devices intended for interruption of current flow in the event of low voltage and / or current pulses in a downstream circuit, which has a spring element capable of A storage element moved between a relaxed position, an opening element for opening the disconnecting mechanism of the electrical switching device, and an activation element, wherein the storage element is configured to pass through the activation element in the tensioned position Outputs stored mechanical energy to the disconnect element when activated. In particular, the auxiliary disconnecting device is characterized in that a displaceably mounted blocking element is provided, which in the first position is operatively connected to the storage element in the tensioned position of the storage element such that The storage element is supported by the locking element; and the locking element releases the storage element to perform a movement when the locking element is in the second position.

Description

technical field [0001] The invention relates to an auxiliary disconnecting device for an electrical switching device and an electrical switching device. Background technique [0002] Auxiliary disconnecting devices are well known for use in electrical switching devices, in particular in circuit breakers. In this case, the task of the auxiliary disconnecting device is to provide the disconnecting device of the electrical switching device with the support. This is the case in particular in circuit breakers with a low-voltage disconnection device and / or a voltage disconnection device, in which electromagnetic disconnection devices are usually used. This type of electromagnetic disconnection device is capable of opening the circuit breaker when a voltage falls below a voltage or when there is no voltage at all. Therefore, this relates to a low voltage disconnect device. Additionally or alternatively, the opening device can open the circuit breaker even in the event of a curr...
