JLSZV-12 (W) Combination Instrument Transformer

Summary
The JLSZV-12(W) is combined voltage and current instrument transformers.The product is used in three-phase systems of rated frequency of 50/60Hz and rated voltage of 12kV. The product is alternative to JLSJW-12 oil-immersed combination transformer.

Product application

The products are provided for metering electric energy, voltage controlling and relay protection. The rated frequency of the electric systems should be 50/60Hz. The products are suitable for outdoor transformer substations in rural areas, as well as for industrial services. It is alternative to JLS-12 oil immersed combination transformer.

Technical specification

1. rated voltage: 3×6kV; 3 ×12kV; 3× 35kV
2. accuracy class: 0.5, 0.2, 0.5S and 0.2S
3. rated voltage ratio: 6k/100; 12k/100; 35k/100
4. rated current ratio: 1~1k/5 A (two type: single ratio and double ratio)
5. Primary wiring of double measuring tank: P1, P2 are heavy current ratio while P1, P3 are high current ratio.
6. Rated burden:
a) PT components: 15, 25 and 50 VA
b) CT components: 10, 25 and 30 VA.

Structure feature
The transformer is outdoor cast in epoxy resin, fully enclosed and is in supporting type structure. For its special casting technique, the product is excellent in electricity-arc and UV ray resistance, long life expectancy, reliable and cost-efficient. The u nits are composed of two single-phase and fully insulated voltage mutual inductors, which are shaped in V . Two current mutual inductors are respectively connected to phase A or C. And the secondary windings of C T units are tapped for varying current ratios.The outlet terminal of secondary windings is covered with a protective cover. It is convenient, safe and reliable for connecting,and efficient in prevention of stealing electricity. Four screws on the base plate are designed for fixing purpose.
