In the paper, the causes of common faults for vacuum on-load tap changer of transformer are systematically analyzed and improvement measures for its reliable operations are deeply discussed aiming at the key effects of its operation stability on power system security. It is found by analysis that the causes of faults for on-load tap changer are various. The service life of equipment is increased, downtime is reduced and overall operating efficiency of power system is improved through such measures as optimization design and model selection as well as normalizing installation and commissioning. Moreover, it is aimed to provide the comprehensive troubleshooting ideas and effective improvement scheme of reliability for operation and maintenance staff of power to ensure the stable operations of vacuum on-load tap changer of transformer so that the reliability of bulk supply for power system is improved.

In the paper, the causes of common faults for vacuum on-load tap changer of transformer are systematically analyzed and improvement measures for its reliable operations are deeply discussed aiming at the key effects of its operation stability on power system security. It is found by analysis that the causes of faults for on-load tap changer are various. The service life of equipment is increased, downtime is reduced and overall operating efficiency of power system is improved through such measures as optimization design and model selection as well as normalizing installation and commissioning. Moreover, it is aimed to provide the comprehensive troubleshooting ideas and effective improvement scheme of reliability for operation and maintenance staff of power to ensure the stable operations of vacuum on-load tap changer of transformer so that the reliability of bulk supply for power system is improved.
