Mining transformer
Mining flameproof mobile substation is composed of mining flameproof dry-type transformer, high-voltage load switch used for mining flameproof mobile substation or high-voltage vacuum switch used for mining flameproof mobile substation as well as cable connector used for mining flameproof mobile substation, low-voltage feed switch used for mining flameproof mobile substation or low-voltage protection case used for mining flameproof mobile substation. Protection properties such as electric leakage, earth leakage lockout. overload, short-circuit, over-voltage, under-voltage. etc.
KBSGZY series of mining flameproof mobile substation is the complete set of mobile power supply and transformation equipment used under coal mine well. It not only is applicable to the well and mine environment with explosion hazard due to existing of methane mixed gas and coal dust, but also is applicable to the gas and steam environments which are insufficient to corrode metal and destroy insulation.
Wind power dedicated box-type booster substation (American type wind power box changes)
In contemporary society with worldwide energy crisis and strong environmental protection consciousness, improvement of energy utilization efficiency and development of renewable energy sources, with no doubt, have become the two aspects of sustainable development energy. Besides, wind energy. which attracts more and more people' s attentions, has become one of the "green energies" with large scales and development and application prospects. Approximately 20% of solar radiation received by the earth can be transformed into wind energy and all energy consumption can be fulfilled if 1% of total amount of wind energy throughout the world can be used for power generation. Therefore, as the main form of wind energy utilization, wind power generation has been developed rapidly in the long run.
Under normal circumstances, the outlet voltage of wind power generating unit adopted by our country is 690V and long-distance power devilry can be realized through pressure boosting. In wind farms, cable is generally adopted to connect the wind driven generator to the wind power dedicated box-type booster substation; the power is delivered to the central substation of the wind farm when it is boosted to 40.5 (12) kV; after that, power is further boosted in the central substation and then be delivered to the power grid; unit wiring of "one transformer for one machine" is adopted for the combination of fan and box-type booster substation. The 40.5kV wind power dedicated box-type booster substation designed and manufactured by our company has been operated in network in wind farms of Inner Mongolia, northwest China, etc.
