Problems solved by technology

[0009] A disadvantage of this known protective switch is that it has a high sluggishness, so that not only the response is delayed, but also the reestablishment time of the normal operating state after an impermissibly high secondary voltage decay is delayed.
Furthermore, such a protective switch can only be accommodated with difficulty in the secondary terminal box of the current converter due to its size, and is moreover expensive and poses problems with regard to operational safety

Embodiment Construction

[0086] Figure 6 A perspective view of an electrical circuit 12 embodied as a protective circuit is shown, which is part of a docking module 22 which has two connecting elements 28.3. Figure 7 A perspective view of the docking module 22 is shown, wherein the housing 26 of the docking module 22 is also visible.

[0087] The circuit 12 is constructed on a circuit board 28, wherein the connection element 28.3 protrudes beyond the circuit board 28 and protrudes from the docking module 22, which is Figure 7 can be seen in . Here, the connecting element is formed as a tongue-shaped lug 28 . 3 , which protrudes from the housing 26 of the docking module 22 , wherein the lug 28 . 3 is formed in particular as a tongue-shaped protrusion of the printed circuit board 28 . Here, web 28.3 is gold-plated on both sides (upper side and lower side).

[0088] The connecting element 28 . 3 can be pressed onto the current converter 10 by means of a screw 30 , wherein the connecting element 28 ...

Abstract

The invention relates to a docking module (22) for a current transformer (10) comprising: an electronic circuit (12) and at least one electric connecting element (28.3) for electrically coupling the circuit (12) to the current transformer (10) and for docking the docking module (22) onto the current transformer (10).

Description

technical field [0001] The invention relates to a docking module for a current converter, which has an electronic circuit, preferably a protective circuit for the current converter, for preventing the secondary voltage at the secondary circuit of the current converter from exceeding secondary voltage threshold. The invention also relates to a current converter comprising a docking module. Background technique [0002] Current converters typically operate with low ohm loads of less than one ohm, such as when using current measuring instruments in the secondary loop. Since the secondary voltage is proportional to the load, the voltage at the secondary terminals can have impermissibly high values ​​during no-load operation of the secondary connection. For this purpose, in order to achieve protection of the transformer when a short-circuit on its secondary side is interrupted, for example when the measuring instrument together with its shunt resistor is removed, protective swi...
