The voltage regulator is a device that makes the output voltage stable. The regulator consists of voltage regulating circuit, control circuit, servo motor, etc. When the input voltage or load changes, the control circuit samples, compares and amplifies, then drives the servo motor to rotate, so that the position of the voltage regulator carbon brush changes, and the output voltage is stable by automatically adjusting the coil turn ratio. So why is it not suitable for household appliances to use voltage regulators?
Since 1998, the state has invested heavily in large-scale urban and rural power grid construction and transformation. Therefore, the quality of power supply for urban and rural residents will be significantly improved, not to mention the need for “voltage regulators”.
In the design of household appliances, the power supply fluctuation in use has been taken into account, and the safety factor has been designed to ensure normal operation within a certain range of voltage fluctuation. If some refrigerators can work normally in the range of 180 ~ 240 volts, please guarantee on the instruction manual. Other household appliances also basically meet this voltage range. At present, the power supply regulators in the market can only play a stabilizing role in this range, beyond this range, they also fail or even damage.
Voltage stabilizer is not suitable for household appliances
Due to the low technical content of power supply regulators, most of the products are produced by self-employed households or small factories, and most of the components used are low-cost secondary products and inferior products, which can only be effective in a short period of time. These products have been inspected and complained by consumers, which proves that there are many fake and inferior products. Some fail in less than half a month, others explode in less than a month, and others burn the refrigerator on fire.
From a technical point of view, some relay power supply regulators can not protect household appliances, but will play a destructive role. When the voltage regulator is cut off and connected in operation, the phenomenon of strong current impact and other damage to household appliances will inevitably occur to some household appliances without capacitors in the power supply.
Therefore, voltage regulator, household appliances should not be used! Do you understand all the knowledge that Xiaobian said? If you want to know more about electric shock prevention for children at home, please continue to pay attention to the recent update of Baibai safety net.
