With the improvement of science and technology and production technology, people's material life has become more and more enriched. Various household appliances and smart home products have become an important part of daily life. In order to improve safety and reduce the hazard of electric shock, household appliances are generally used Low-voltage power supply, the working voltage is generally 6V, 9V, 12V, 15V, 18V, 24V, 36V, etc. In order to reduce the power transmission loss and improve the transmission efficiency, the power supply voltage of the grid is higher than the human body safety voltage of 36V. At this time, a transformer is needed Transform the grid distribution voltage into a suitable supply voltage; the transformer used for home appliances is usually an isolation step-down transformer. It can not only prevent fatal injuries caused by electric shock in daily life, but also isolate various electrical appliances from the power supply grid. When the electrical equipment is abnormal Or when a short circuit occurs, it effectively limits the short-circuit current of the power grid and reduces the impact on the power grid voltage. The insulation materials of transformers for household appliances are all fireproof materials and are equipped with temperature protection devices. When the electrical equipment works abnormally or a short circuit causes the temperature of the transformer to reach the protection temperature, it will automatically Cut off power to avoid and reduce the occurrence of man-made disasters.
