8 maintenance tips of three phase voltage stabilizer
- Do not operate under overload, and try to stagger the peak load.
- Clean up the dust and disconnect the power supply of the power supply before maintenance to ensure safety.
- Whether the installed model meets the environmental requirements, if not, please improve.
- Carefully clean all parts, especially the carbon brush, contact the exposed part of the coil, and remove the dirt.
- Under the installation environment of high-precision voltage stabilizer, ventilation shall be ensured, and the ambient temperature and body temperature shall be normal.
- Before the seasonal conversion, the transformer and high-precision voltage stabilizer shall be thoroughly maintained to remove the potential safety hazards.
- Replace the worn or damaged carbon brush in time, and repair or replace the faulty or damaged components in time.
- Check whether the internal parts and wire ends of high-precision voltage stabilizer are loose. If there is loose connection or poor contact, handle it in time.
