Abstract: A system for monitoring a switchgear includes: an infrared camera for acquiring at least one infrared image of the switchgear; a processing unit for determining a pixel in the at least one infrared image associated with a hottest temperature, determining e pixels in the at least one infrared image associated with a temperature that is within a threshold temperature of the hottest temperature, and determining that a hot spot exists in the switchgear as a determination, the determination being a utilization of the determined pixels in the at least one infrared image; and an output unit for outputting an indication of a fault in the switchgear based on the determined hot spot.

Abstract: An arrangement for electrically connecting a circuit breaker to a laminated busbar in a switch gear cabinet in which the circuit breaker has at least one terminal to be contacted by a connecting bar and in which the laminated busbar includes at least one conducting layer for conducting electric current which is covered by adjoining insulating layers attached thereto, the arrangement including: a first cylindrical connecting element and a second cylindrical connecting element which are arranged at a distance to each other at the conducting layer and project away from the conducting layer; an electrically conducting distribution bar which is mounted to free end portions of the first and second cylindrical connecting elements; and a terminal member which is mounted to the distribution bar at a center between the first and second cylindrical connecting elements. The terminal member is to be contacted by the connecting bar.

Abstract: A cooling system includes an evaporator associated with a heat source. A condenser is located at a higher elevation than the evaporator. A heat pipe structure fluidly connects the evaporator with the condenser. A fan forces air through the condenser. A working fluid is in the evaporator so as to be heated to a vapor state, with the heat pipe structure transferring the vapor to the condenser and passively returning condensed working fluid back to the evaporator for cooling of the heat source. A plurality of thermoelectric generators is associated with the condenser and converts heat, obtained from the working fluid in the vapor state, to electrical energy to power the fan absent an external power source. The thermoelectric generators provide the electrical energy to the fan so that a rotational speed of the fan is automatically self-regulating to either increase or decrease based on a varying heat load.
