- Details
Whether used in distribution systems, substations, or other power equipment, this series of on-load tap-changers provides a stable and reliable voltage regulation solution to meet the needs of diverse scenarios. Whether in industry, agriculture, or construction, it delivers superior voltage control performance for your power equipment, ensuring the normal operation of your power supply system.
Tap-changer operating conditions:
1. The installation location must be free of heavy dust, explosive gases, and corrosive gases.
2. The switch should be stored in an ambient temperature range of -25°C to 45°C.
3. The switch should be used in transformer oil, and the oil temperature should be between -25°C and 100°C.
4. When the switch is mounted on the transformer, the vertical tilt should not exceed 2%.
Key Features and Advantages:
1. High Reliability
High-quality materials and advanced manufacturing processes ensure product stability and reliability, making it less prone to failure during long-term operation.
2. Flexible Adjustment
Through tap-changing operations, the line voltage can be flexibly adjusted according to actual needs, meeting voltage regulation requirements under varying load conditions.
3. Precise Control
A sophisticated tap-changing mechanism and reliable control system ensure accurate control and stability of the tap position.
4. Safety and Reliability
Multiple safety protection devices, such as overcurrent protection and short-circuit protection, ensure safe and reliable operation.
5. High Energy Efficiency
