Description

Technical Field

[0001] This invention relates to the field of voltage regulator technology, specifically to a voltage regulator with a stability protection function. Background Technology

[0002] As is well known, a voltage regulator is a device designed in electronic engineering to automatically maintain a constant voltage. It is mainly used to adjust the voltage, that is, to control the power supply voltage that fluctuates greatly and cannot meet the requirements of electrical equipment within its set value range, so that each circuit or electrical equipment can work normally under the rated operating voltage.

[0003] Most existing voltage regulators follow the same process: when the input voltage or load changes, the control circuit samples, compares, and amplifies the signal, then drives a servo motor to rotate, changing the position of the regulator's carbon brushes. By automatically adjusting the coil turns ratio, the output voltage is kept stable. However, carbon brushes generate heat during use, leading to wear. If the regulator's internal temperature reaches a high level, it may damage surrounding components, causing power surges and affecting the regulator's operation. Furthermore, ambient humidity significantly impacts the lifespan of carbon brushes, increasing workload and costs. Additionally, some voltage regulators experience momentary voltage fluctuations due to load changes, which also affect stability. Therefore, a voltage regulator with stability protection is needed.

[0047] Working principle:

[0048] When using this voltage regulator with stability protection function, first place the voltage regulator with stability protection function in the desired position, and then inject anhydrous glycerin. The specific operation is as follows: drag the lifting block 1205. The movement of the lifting block 1205 causes the tube plug 1204 to move, exposing the inlet. Pour the anhydrous glycerin into the inside of the heat absorption tube 1203 through the inlet.

[0049] Finally, the voltage regulator is started. The specific operation is as follows: pull the switch handle 20. The rotation of the switch handle 20 drives the protection switch 21 to open. At the same time, the unstable voltage enters the voltage regulator through the capacitor 1405. The control circuit board 8 samples, compares, and amplifies the voltage, and then drives the servo motor 9 to rotate, causing the carbon brush 1508 to change position. Multiple damping pads 1301 work together to absorb the vibration generated when the servo motor 9 is working. The movement of the carbon brush 1508 drives the first spring 1302 to move. At the same time, the cooling fan 16 and the dehumidifier 22 work simultaneously to keep the inside of the voltage regulator dry. Finally, the stabilized voltage is delivered to the outside through the capacitor 1405.
