Description

This three - phase 11kV/22kV grounding transformer is tailor - made for medium - voltage power grids. By creating an artificial neutral point, it accurately achieves the grounding protection function and is suitable for various distribution system scenarios. When facing single - phase grounding faults, it can effectively handle them, building a solid defense for the stable operation of urban power grids and industrial power facilities, and ensuring the reliable power supply of the power system.

Features

• Flexible Voltage Adaptation: Supports 11kV and 22kV voltage systems, accurately matches the specifications of common medium - voltage power grids, is widely adaptable to diverse power application scenarios, and has strong compatibility.
• Intelligent Fault Management: When encountering single - phase faults, it quickly suppresses arc - grounding overvoltages, greatly reduces fault currents, reduces the risk of damage to power equipment, and improves the operation and maintenance efficiency of the system.
• Reliable and Robust Structure: Adopts high - quality iron cores, durable windings, and is matched with a robust shell. It effectively resists the erosion of harsh environments such as moisture and dust, ensures the long - term stable operation of the equipment, and reduces maintenance costs.
• Comprehensive Safety Assurance: Stably provides neutral point grounding, prevents voltage fluctuations and insulation faults from the source, safeguards the safety of the power grid and associated electrical equipment, and builds a solid foundation for the safety of the power system.
