Selection parameter table:
Provide a variety of rated primary current and accuracy level combinations, as well as the corresponding rated secondary output, short-time thermal current and dynamic stabilization current.
Rated Primary Current
Principle of operation:
The current transformer consists of a silicon steel toroidal core, wound with multiple turns of copper wire, the conductor containing the primary current passes through the ring, generating an alternating magnetic field, which induces a secondary AC current in the core.
The secondary AC current is induced in the core.
Role:
Used for the protection, measurement and control of high-voltage substations and power grids
Function.
Installation use and maintenance:
Before using the transformer, the grounding bolt should be properly grounded, the secondary winding must be reliably connected to the load, and the secondary winding not in use must be shorted to the secondary outlet terminal.
The secondary winding must be connected to the load reliably before use.
Outline and installation dimensions:
Specific external dimensions and installation dimensions can be referred to the product manual or contact the supplier for detailed information.
LZZBJ.
In summary, LZZBJ71-35 type 35KV outdoor dry current transformer is a hot selling quality transformer with its excellent performance and stability, suitable for current measurement and protection in outdoor high voltage power systems.
