    • A compact drive unit is predominantly intended for traction vehicles, especially for rail vehicles. This invention allows significant reduction of volume and weight of drive units. The drive unit comprises high-speed electrical motor (1) with passive cooling, which is supplied by power electronics converter (2), whose rotor is supported by bearings (3) along with pinion gear (4) of the input spur/helical gear (5). The output shaft (6) of the gear (5) is a part of the next following gear (7). Output shaft of this gear (7) can be connected either directly or by using the coupling (12) to the axle (8) of the traction vehicle, or to the wheel (9). Alternatively, in case the higher transmission ratio is required, it can be connected to another gears (10), where the output shaft of the gears (10) is connected to the wheel (9), or to the axle (8) of the traction vehicle directly or by using the coupling (12). The drive unit can be equipped with brake (13).

    • The design relates to the process of quantitative measurement of generation or consumption of gases, particularly operational measurement of generation or consumption of gases in power transformers and device suitable for implementation of such a method.
      The whole process of quantitative measurement in carried out in two steps. At first, the rate of flow of oil is examined as the oil is considered the carrier of all gases between the tank (10) of the transformer (1) and the conserver (11) implemented in the form of a dynamic change in calibration gas concentration within the oil filling (12) of the tank (10) of the transformer (1). Regarding the fact that the known volume of the oil filling (12) of the tank (10) of the transformer (1) is utilized as a well-definable capacity enabling the required dynamic change to occur in it.
      The required change of calibration gas concentration within the oil filling (12) can also be achieved by two basic methods of the procedure:
      If nitrogen N is utilized as the calibration gas, always presented in the oil filling, the oil filling (12) is vacuum treated, and subsequently the time interval based on a process of a natural reverse saturation of oil filling (12) is measured by nitrogen from the surrounding air environment.
      The second procedure employs the method of compressive saturation of oil filling of the transformer implemented by the calibration gas, which is not contained in such oil filling under standard circumstances. The calibration gas is forced to supply the oil filling of the conserver (11) and consequently the growth of its concentration is measured in the oil filling (12) of the tank (10) of the transformer (1).
      From the results of measured calibration gas concentration gradient in the oil filling (12) and values of calibration gas concentrations both in oil filling (12) of the tank (10) and in the oil filling of the conserver (11) is defined the volume flow rate between both tanks (10).
      By means of known values of oil rate of flow determined between the tank (10) of the transformer (1) and the conserver (11) and the time sequence of measured concentrations of all monitored gases examined by the DGA analyser (3) in both tanks (10), flows per all monitored gases corresponding with the generation or consumption of such gases in the tank (10) of the transformer (1) are defined in the quantitative way.
