High-current Instrument Transformer for Generators
- Compliant Standards: GB/T 20840.1, IEC 61869-1; GB/T 20840.2, IEC 61869-2; and special customer requirements.
- Structural Overview:
- Installed on the generator outlet or neutral point bushing. This series of current transformers adopts a winding structure, with the transformer fixed on an insulating plate. It is mounted on the generator bushing through four holes on the insulating plate, using the high-voltage outlet bushing as the main insulation.
- Installed within the enclosed busbar between the generator and the transformer. This series of current transformers adopts an epoxy resin vacuum casting structure, fixed to the enclosed busbar housing via four embedded nuts on the outer diameter of the transformer body.
- Product Features: Compact structure, lightweight, and easy to install. The bushing-type current transformer employs internal magnetic shielding technology to effectively prevent magnetic field interference caused by high currents in adjacent phase busbars, ensuring accuracy and meeting the requirements for long-term safe operation.
- Application Fields: This series of current transformers is widely used in nuclear power, thermal power, and hydropower units for generator electrical protection and measurement.
