Embodiment Construction

[0026] FIG. 1 shows a schematic diagram of an exemplary embodiment of a testing device 1 . The testing device 1 is used for testing a switch cabinet 2 in which at least one protective device 4 is arranged for monitoring a power supply network 3 . Furthermore, the switch cabinet 2 also contains an input terminal module 5 .

[0027] The input terminal module 5 has a plurality of individual terminals, some of which are designed as current transformer terminals 6 and 7 and another part as circuit breaker terminal 8 in the exemplary embodiment according to FIG. 1 . Each of these individual terminals has an input connection contact 9 and a cabinet connection contact 10 as main contacts, which are each embodied as screw contacts.

[0028] The input connection contacts 9 of the current transformer terminals 6 are connected to a current transformer 11 arranged outside the switch cabinet 2 , which detects the current in the electrical lines L1 , L2 and L3 of the power supply network 3 ...

Abstract

The invention relates to a detection device for a detecting switch cabinet (2), comprising an input terminal module (5) with multiple single terminals (6, 7, 8) and mounted on the switch cabinet (2). Each single terminal (6, 7, 8) comprises an input connection contact (9) used for connecting a device (11) provided outside the switch cabinet (2) or electrically connecting a conducting wire (12); a cabinet connection contact (10) used for connecting a device (4) provided inside the switch cabinet (2) or electrically connecting a conducting wire (15); a first terminal detecting contact (18) connected on the input connection contact (9); a second terminal detecting contact (19) connected on the cabinet connection contact (10); and a separating switch (20) with one side provided between the input connection contact (9) and the first terminal detecting contact (18) and the other side provided between the cabinet connection contact (10) and the second terminal detecting contact (19).

Description

technical field [0001] The invention relates to a testing device for a switch cabinet comprising an input terminal module mounted on the switch cabinet with a plurality of individual terminals. Background technique [0002] The reliability of the devices used in switchgear and / or power stations for monitoring and controlling electrical operating devices must be checked during commissioning and, if necessary, required maintenance. These devices can in particular be protective devices arranged in the switch cabinet. [0003] Currently, test switches or test modules are used, by means of which the test device can be connected to the device arranged in the switch cabinet and to be tested. These test switches or test modules are connected to the circuit inside the switch cabinet by means of special wiring. The test switches or test modules and their connecting wiring constitute additional expenditure. Furthermore, it is only possible to test the electrical circuits inside the ...
