10kV plate vacuum on-load voltage regulation tap changer
Model
For example, , SYⅤTZZ 50/10-5XZ ,as the triple-phase on-load terminal voltage regulation, adopts transitional resistance, direct switching load switch, the maximum through-current is 50A, the highest voltage for equipment is 10kV, it has 5 tapping gear positions, horizontal structure, vacuum arc removal.
This product meets the bidding requirements of State Grid and has been included in the standardized drawings of State Grid.
Advantage
Its contacts and transition contacts adopt double-layer sandwich structure, which can withstand greater short circuit current impact and fully meet the short circuit current impact requirements of state grid for distribution transformer.
1.The unique operation technology is adopted to solve the problem that the tap changer can not be adjusted without power supply, which greatly facilitates the field operation and maintenance and troubleshooting.
2.Electrical and physical dual gear indication is used to solve the inconsistency between the actual switch and the controller reading gear caused by the motor turnover, and improve the safety and reliability of the switch.
3.The fully sealed precision speed reduction box + stepper motor technology is adopted to solve the problem of mechanism corrosion lag caused by water or moisture, and to ensure the stable operation for a long time.
