MB Pre-Installed Substation (American) Fully Insulated High-Voltage IP33
Summarize
This product is the absorption of foreign advanced technology, combined with the actual situation of domestic research and development, the whole product has the characteristics of small size, easy installation and maintenance, low noise, low loss, anti-theft,overload capacity, full protection. Applicable to new residential areas, green belts, parks, station hotels, construction sites, airports and other places.
MB Pre-installed box substation (American),suitable for 10kV loop power supply, dual power supply or terminal power supply system, as a power transformation,metering,compensation
control and protection device.
This product meets the following standards:GB/T17467-1998 "High voltage and low voltage preassembled substation"; DL/T537-93"Technical Conditions for ordering 6-35kVbox-type
substation".
Normal service condition
●Altitude does not exceed 1000m;
●Ambient temperature:-35℃~+40℃;
●Relative humidity: daily average is not more than 95%, monthly average is not more than 90%;
●Installation site: no fire, explosion danger,chemical corrosive gas and well-ventilated place, the ground inclination is not more than 3°.
Function and characteristics
●Fully insulated, fully sealed, no less maintenance, reliable guarantee of personal safety;
●Compact structure, volume is only 1/3-1/5 of the same capacity, low height;
●Can be divided box structure, to avoid the oil pollution in the transformer tank;
●The high voltage side adopts double fuse full range protection, greatly reducing the cost;
●Can be used for ring network, can also be used for terminal, cable head can be in 200A load current emergency plug;
●The box is made of non-embroidered steel material, which has the function of temperature insulation and heat dissipation;
●Low voltage side is equipped with electronic phase loss protector, when there is abnormal voltage in the system, it can quickly break the main inlet switch;
●High pressure side oil-immersed load switch, which can be electrically upgraded, laying the foundation for realizing the automation of distribution network;
●Use oil-immersed S11 or S13 series transformers with better performance.
