DAHU electrical specializes in the production of 0.5-40.5kv transformers. It has cooperated with many national power bureaus for 10 years and exported to foreign markets. If
there is any quality problem within the warranty period, it can be replaced free of charge.
Product Overview:
LZZBJ9-10A current transformer is an epoxy resin casting pillar type full working condition product, suitable for rated frequency of 50Hz, rated voltage of 10kV and below in the power system, used for relay protection or power measurement.
It is suitable for power system with rated frequency 50Hz and rated voltage 10kV and below, for relay protection or power measurement.
Technical parameters:
Rated current ratio: 5~400A/5A, 500/5A, 600/5A, 750/5A, 800/5A, 1000/5A, 1200/5A, 1500/5A, 2000/5A.
Accurate level combination: 0.2S/0.5, 0.2S/10P10, 0.5/10P10.
Rated output (VA): Rated output varies according to different rated current ratios, e.g. 10/10VA, 15/15VA, 20/20VA, etc.
Dynamic stabilizing current (kA) (peak) and rated short-time thermal current (kA) (RMS): these parameters vary according to different combinations of accuracy levels, e.g., for 0.2S/0.5 level, the dynamic stabilizing current is 225kA and the rated short-time thermal current is 90kA
.
Insulation level:
Rated insulation level: 12/42/75kV
.

The secondary wiring is equipped with a junction box, and there are four mounting holes on the bottom plate for installation.
The product has 4 mounting holes on the base plate for installation.
Application Scenario:
Suitable for current and power measurement and relay protection in power systems, especially in indoor high-voltage cabinets.
Installation and Maintenance.
Installation and maintenance:
The transformer arrives at the use of units need to do inspection, including packing list, product certification, instruction manual and factory certificate of conformity.
The grounding bolt should be properly grounded before using the transformer.
During operation, 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 to ensure safety.
The secondary winding must be connected to the load reliably during operation.
