Mine dry-type packages in combination transforming devices birth |
|
| By Yanzhou Mining (Group) Company and China coal mine Natun Advisory Group Wuhan engineering design of the jointly developed by the dry-type packages Zbk-mine portfolio transforming devices, recently adopted Chinese coal Construction Corporation Organization expert technical experts. Such devices are used by the mine transformer cabinets, a high-voltage switches mining equipment, mining equipment using low voltage switches three components. High and low voltage switches are equipped with the total equipment switches, sub-owned switches between vertical and horizontal selective leakage protection, the power supply system to ensure the safe and reliable operation, and a large capacity, small size, low loss characteristics, can replace the current coal miners in the widespread use of transformers Youjin, thoroughly avoided caused by the transformer fires. Through the use of coal mine site certification practice, the main results of this study apply to the bottom of the well maintained coal miners, the total removal or other requirements into the wind with the general use of mine-type transformers product sites, the following three-phase exchanges as 10kV not grounded neutral point of the high-low voltage electricity transmission system packages devices, have good values and extensive promotional value.
