Brief Introduction about Tunnel high-power three-phase oil immersed voltage regulator below:
Product details:
1、 Working principle
The working principle of oil immersed voltage regulators is based on the principle of transformers, combined with automatic voltage regulation function. The voltage regulator consists of high and low voltage windings and an automatic regulating device. In the case of input voltage fluctuations, the automatic adjustment device inside the voltage regulator achieves stable output voltage by controlling the output point of the transformer. When the input voltage is too high or too low, the voltage regulator can automatically adjust the output voltage to the set value, maintain voltage stability, and ensure the normal operation of downstream electrical equipment.
2、 Oil immersed cooling method
One of the core advantages of oil immersed voltage regulators is the use of an oil immersed cooling system. The stabilizer is filled with special electrical insulation oil inside, which utilizes the good thermal conductivity of the oil to dissipate the heat generated during equipment operation. Oil immersed cooling can effectively reduce equipment temperature and avoid damage to equipment due to overheating. Compared with air cooling systems, oil immersed cooling has a stronger heat dissipation effect and can operate stably for a long time under higher power loads.
Oil immersed cooling method can not only improve the stability of equipment, but also extend the service life of voltage regulators. Due to the high insulation performance of oil, the insulation effect of oil immersed voltage regulators is relatively good, which can ensure the safe operation of equipment in high voltage environments.
3、 Intelligence and remote monitoring
Modern oil immersed regulators are usually equipped with intelligent control systems and remote monitoring functions. Users can view the operating status of the regulator in real time through the display screen, including key data such as input voltage, output voltage, current, power factor, etc. In addition, the device also has a self diagnostic function, which can automatically alarm when a fault occurs, and locate the fault through an intelligent control system to help users solve problems in a timely manner.
The remote monitoring function makes device operation more convenient, and users can remotely manage, view the working status of devices, and adjust and set parameters through the network without physically visiting the site. This function plays an important role in large industrial and power systems, improving equipment management efficiency and reducing manual intervention and maintenance costs.
4、 Security protection mechanism
In order to ensure the safe and stable operation of equipment, oil immersed regulators are usually equipped with multiple protection functions, including overload protection, overvoltage protection, short circuit protection, and over temperature protection. When there is an abnormal situation with the voltage regulator, these protective functions will automatically activate, cut off the power, and prevent further damage to the equipment or safety accidents.
For example, when the input voltage is too high or too low, the voltage regulator will automatically adjust the output voltage to prevent damage to downstream equipment. If the device temperature is too high, the over temperature protection will cut off the power supply to avoid overheating damage and ensure the long-term stable operation of the device.
