Embodiment Construction

[0032] figure 1 A schematic block circuit diagram is shown for illustrating an exemplary embodiment of the device 1 according to the invention. In a possible embodiment, the device 1 is a welding device which supplies an adjustable current to the welding torch. The welding device 1 can comprise a number of different parts or components, which serve on the one hand as control electronics and on the other hand for power electronics purposes. For example, these components or parts include electronic or electromechanical components. figure 1 Two components 2 - 1 , 2 - 2 are shown schematically, for example as electronic components or electronic assemblies. The two components or assemblies 2 - 1 , 2 - 2 have an operating temperature T which, in the embodiment shown, is detected by associated temperature sensors 3 - 1 , 3 - 2 . These temperature sensors each detect an operating temperature development T(t) of an associated component or associated assembly within the welding devic...

Abstract

The invention relates to a device (1) for providing electric power, wherein the device (1) comprises: at least one integrated temperature sensor (3-1, 3-2), which measures an operating temperature profile of at least one component (2-1, 2-2) of the device (1), and a monitoring unit (5), which monitors the operating state of a device cooling of the device (1) on the basis of the at least one measured operating temperature profile and of the set power.

Description

technical field [0001] The invention relates to a device for monitoring a device cooling structure being monitored, as well as a method for monitoring the operating state of a device for supplying or converting electric current, in particular a device cooling structure in an energy device. Such energy devices include battery charging devices, inverters and welding devices. Background technique [0002] The welding device has a welding current source that supplies electric current to perform welding work. The welding inverter forms the electronic welding current source. Inverter welding devices are used for different arc welding operations, such as electrode welding, MIG / MAG welding, plasma welding and WIG / TIG welding. Depending on the electricity involved, such devices are connected to the grid either in single-phase or three-phase. In the case of welded inverters, the grid voltage is first rectified and chopped with the help of power semiconductors and converted to a low...
