1. Switch cabinet for servers and similar devices, in particular parts of sensitive computer devices, whose interior (2) is connected to gas bottles (25, 26) that contain a fire extinguishing gas and supplied continuously with fresh air via a ventilator (14), with early fire detection sensors (16, 17) being installed in the exhaust air current outside the interior area (2) and the connection (33) being activated in case of fire, characterized by the fact that the interior (2) is designed in a protective cabinet (1) that is closed off from the atmosphere, that the gas bottles (25, 26) which are activated via the early fire detection sensors (16, 17) in case of fire are filled with the noble gas argon, that the interior (2) is connected to the atmosphere via a supply tube (7) which is equipped with an intake and exhaust air nozzle combination (15) with screen (41) that is located at the end situated outside the protective cabinet (1), and that the early fire detection sensors (16, 17) and the entire control system (18) are assigned to an additional cabinet (11) that is allocated to the protective cabinet (1). 2. Switch cabinet according to one of the previous claims, characterized by the fact that the additional cabinet (11) is adjusted to the upper part (12) of the protective cabinet (1), also includes the ventilator (14) and is connected to the upper part (12). 3. Switch cabinet according to one of the previous claims, characterized by the fact that the ventilator (14) is switched on suction during normal operation and stopped by the control system (18) in case of fire. 4. Switch cabinet according to one of the previous claims, characterized by the fact that the additional cabinet (11) is connected to the interior (2) via an intake tube (46), which is equipped with several bores (9, 10) throughout its entire length. 5. Switch cabinet according to one of the previous claims, characterized by the fact that the connection (33) between the gas bottles (25, 26) and the protective cabinet (1) is designed as a conduit, which ends in the covering wall (35) of the protective cabinet (1) in the form of a high pressure gas nozzle. 6. Switch cabinet according to claim 5, characterized by the fact that the high pressure gas nozzle (8) is designed to include a warm-up outlet (36) and a relaxation and distribution chamber (37). 7. Switch cabinet according to one of the previous claims, characterized by the fact that the additional cabinet (11) is equipped with mounting devices (40) for the gas bottles (25, 26) on the upper side (39). 8. Switch cabinet according to one of the previous claims, characterized by the fact that at least two early fire detection sensors (16, 17) are provided for, which have different switching times, with the one having the shorter switching time being connected to the control system (18) and the server andlor data protection device and the one having the longer switching time to the control system (18) and the extinguishing part (19). 9. Switch cabinet according to one of the previous claims, characterized by the fact that the control system (18) is simultaneously equipped as a fire alarm device (20) and connected to the extinguishing part (19) and a fire alarm center (21). 10.
