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.
Accuracy class description:
Voltage transformer accuracy class 0.5 means that under the rated load, the measurement error of the transformer will not exceed ± 0.5%.
voltage transformer:
Apply to the rated frequency of 50Hz or 60Hz, rated voltage of 10kV power system, for power measurement, voltage monitoring and relay protection. Product implementation standards for GB/T20840.1,3 and IEC61869-1,3.
Technical parameters:
For the voltage transformer with 0.5 level accuracy, the capacity used is 50 VA under the load power factor cosφ=0.8.
Application Scenario:
In the 10kV distribution system, the voltage transformer often has abnormal faults such as one-phase or two-phase melting of the high-voltage fuse, which affects the accurate metering of the power meter, and may cause the false operation of the protection device and the automatic device, jeopardizing the safe and stable operation of the distribution network.
Structural characteristics:
JDZJ-10 type voltage transformer for single-phase epoxy resin cast insulation voltage transformer, small size, strong climate adaptability. The first and second windings and auxiliary secondary windings are concentrically wound in the core, cast with epoxy resin as a whole, for the fully insulated structure.
Installation and use:
10kV voltage transformer in the power system has a variety of wiring, wiring grounding, phasing, etc. must be in accordance with strict connection, and the voltage transformer secondary side is strictly prohibited short circuit.
The above information provides a basic overview of 10kV, accuracy level 0.5 indoor voltage measuring instrument, including the meaning of its accuracy level, technical parameters, application scenarios and structural features. These voltage transformers are essential for ensuring stable operation and safe protection of power systems.
