The image shows KBSGZY（-T）Series Flameproof Dry-Type transformer. Final configuration, colour and attachments are confirmed at order stage — please request current photos before purchase.
KBSGZY(-T) series flameproof mobile substation is composed of the dry-type transformer, HV vacuum switchgear, LV protection box, suitable for the place inthe mixed air of coal dust and methane and the underground coal mine. It can achieve the primary and secondary voltage and current transition to constitutethe HV advanced protection model of the LV fault analysis. This product conforms to GB3836, GB8286, GB1094, AQ1043 and other standards at home and abroad.
Product Features
1. British-style square corrugated heat-dissipation flameproof enclosure with the oriented heating panel inside,this enclosure has the excellent impact resistance
2. German-style circular rippleheat-dissipation flameproof enclosure with high wave crest, short pitch ofwaves, one hydraulic forming and excellent heat dissipation
3. High temperature classification,reliable insulation, long life and better environmental protection because ofthe American Dupon NOMEX insulation system
4. The application of VPI vacuum pressure impregnationtechnology enhances the reliability of the electrification and improves themechanical strength ad moisture resistance performance of the welding.
5. Low loss design, superior performanceof the electrification, strong overload capability and maintenance free
6. Compete protective functions, such asoverload, short circuit, loss of phase, under voltage, overvoltage, over heatand other protections
7. Advanced automation communication system in the pit to achieve “fourremote control” functions
8. Unique mechanical interlock andelectric interlocking functions make the operation more reliable
9. Intelligent and comprehensiveprotection, human-computer interaction interface with Chinese character demonstration
10. It is more convenient for the mobilepower supply in the underground mine with the design of enclosed mine wheels.
