Le BWY-802 et 803 les contrôleurs de température en série adoptent la technologie des capteurs composites, c'est, le paquet de température de l'instrument pousse l'élément élastique et émet simultanément le signal de résistance thermique Pt100. Ce signal peut être détecté à distance vers la salle de contrôle à distance, et la température de l'huile du transformateur peut être affichée et contrôlée de manière synchrone via le contrôleur de température à affichage numérique XMT. Le signal de résistance thermique Pt100 peut également être converti en signal standard DC (0~5) V, (4~20 mA) and RS485 communication interface output with the computer Internet through the digital display instrument.
Introduction to Oil Level Contrôleur de température for Oil Immersed Transformers
The BWY series transformer oil surface temperature controller is designed specifically for measuring and controlling the top oil temperature of transformers. The instrument has good protective performance and can be used normally for a long time under outdoor conditions. The instrument is equipped with three sets of adjustable temperature switches, which are used for starting multiple cooling systems, overheating alarms, etc.. En même temps, the temperature signal can be remotely transmitted to the computer system to achieve synchronous display and control of transformer temperature.
The working principle of the thermostat is as follows
The temperature controller mainly consists of elastic elements, capillaries, and temperature sensing packages. The sealing system composed of these three parts is filled with temperature sensing medium. Quand la température change, the volume of the temperature sensing medium inside the temperature sensing component also changes. This volume increment is transmitted to the elastic element inside the instrument through a capillary tube, causing a corresponding displacement. After being amplified by the mechanism, this displacement drives the pointer to indicate temperature changes and drives a micro temperature switch to control the corresponding cooling system, achieving the goal of controlling the temperature rise of the transformer.
