The alarm device 610 and the conductive terminal 620 shown in Figure 1 are connected in series in the alarm circuit 600; among them, the alarm circuit 600 is connected in parallel with the main control circuit 500 of the switch cabinet. The conductive terminal 620 is disconnected under normal conditions and is connected when contacted by a non-insulating object, so that the alarm device 610 is connected to the main control circuit 500 of the switch cabinet and alarms.

[0063] In this embodiment, the alarm circuit 600 is connected in parallel with the main control circuit 500 of the switch cabinet. In the alarm circuit 600, the alarm device 610 and the conductive terminal 620 are connected in series.
