Device for preventing the effects of moisture condensation in electrical equipment

摘要

Such a device for preventing the effects of moisture condensation is used in electronic equipment, especially in electronic computers, terminals, disk drives, components and the like. In this case, the electronic equipment is arranged in housings, (2), and when a fan (6) is used, the fan (6) is switched on at the same time as the equipment is switched on. In order to prevent malfunction, or even complete destruction, of the electronic equipment, it is proposed to provide at least one measuring means (8) for the external temperature and at least one measuring means (9) for the body temperature of an electronic or electromechanical unit (10), respectively, and to produce a differential value using a differential-value circuit (12), which value, when it exceeds a predetermined threshold value, acts as a switching signal for a circuit breaker (28) which interrupts the power supply (32, 33) of the electronic or electromechanical unit (10), respectively. <IMAGE>
