Model meaning:

Technical parameters:

Performance parameters of dry transformer for explosion-proof AC mobile substation for mining with primary rated voltage of 6kV

Performance parameters of dry transformer for explosion-proof AC mobile substation for mining with primary rated voltage of 10kV

1. Low no-load loss

The high-quality cold rolled grain-oriented silicon steel sheet with high permeability and low loss is adopted for manufacturing. 45° fully-beveled seam and multi-stage step stacking structure, which effectively reduces no-load loss, no-load current and noise.

2. Low noise

The noise is from the iron core, and is transferred to the surrounding through the shell. The connecting position is added with silica gel plate, which cuts off the noise spreading approach.

3. Light weight and small volume

4. The converter mobile substation has explosion-proof and damp-proof performance.

5. The converter mobile substation has perfect overload, short circuit and leakage protection. There is electrical interlock or mechanical interlock device between the high- and low-voltage switches and the high-voltage switch and the circuit breaker of the upper stage.

6. Energy conservation and environmental protection

1) Nomex paper-wrapped line with insulation grade C imported from American DuPont Company is adopted, air insulation and cooling. It has no pollution on the environment, and the product has long service life; the product can be decomposed for recovery after the service life is ended;

2) The high-quality 30Q130 cold-rolled oriented silicon steel sheet and oxygen-free copper conductor are adopted, so that the actual total loss is lower than that of the foreign similar products, which saves the energy, and lowers noise. The iron core surface is applied with the high-temperature-resistant rust-proof and damp-proof paint, Grade H insulation material is adopted for the iron core insulator, and there is no damage after operation at high temperature for a long term.
