Explosion-proof and intrinsically safe (converter) mobile substations for mines

Intelligent Working Face
The mine explosion-proof and intrinsically safe (converter) mobile substation is a mobile complete set of devices that combine high-voltage vacuum switches for mine explosion-proof and intrinsically safe (converter) mobile substations, dry-type transformers for mine explosion-proof (converter) mobile substations, and low-voltage side protection boxes for mine explosion-proof and intrinsically safe (converter) mobile substations. Suitable for mines with explosion hazards, providing power for comprehensive mechanized mining equipment.
This series features an intelligent integrated protection system, user-friendly interaction methods, and convenient installation and usage conditions, making it widely applicable in mine mining.
Dry-type
transformer for mining explosion-proof mobile substations Product features:
1. The core of the dry-type transformer for mining explosion-proof mobile substations uses high-quality grain-oriented cold-rolled silicon steel sheets, with a 45° full slant five-seam, no punching, three-phase three-column structure. The core surface is coated with H-grade heat-resistant and moisture-proof cover paint, the core column is tied with H-grade semi-dry thin weft bands, and the entire unit body uses a tension screw pressing structure for tightening with screw rods, resulting in low no-load loss and low noise.
2. The high and low voltage coils of the dry-type transformer for mine-use explosion-proof mobile substations use a cylindrical structure. Each coil is equipped with longitudinal air channels, providing strong heat dissipation performance and further reducing internal temperature rise; The coil wire uses NOMEX-410 paper-wrapped oxygen-free flat copper wire with a Class C insulation system; The high and low voltage coils use a combined winding process and vacuum pressure impregnation painting technology, resulting in high mechanical strength and excellent heat dissipation.
3. The body of the dry-type transformer for mine-use explosion-proof mobile substations undergoes three rounds of insulating varnish impregnation treatment, and finally the entire surface is covered with a layer of H-grade heat-resistant and moisture-proof insulating varnish, giving it excellent "three protections" capability; During the assembly process, all insulation materials used are H-class or C-grade insulated double Malaysian glass fabric panels, offering high insulation performance and excellent temperature resistance.

4. The explosion-proof shell of dry-type transformers for mining explosion-proof mobile substations adopts a structure with either two ends or an open top, and both the edge of the box cover and the shell edge are explosion-proof surfaces. The sides of the shell feature a corrugated profiled structure, effectively enhancing the product's mechanical strength and heat dissipation performance.
