This product is developed by absorbing the latest foreign advanced technology and combining with the actual domestic situation. The whole product has the characteristics of small size, easy installation and maintenance, low noise, low loss, anti-theft, strong overload capacity, and full protection. It is suitable for new residential areas, green belts, parks, station hotels, construction sites, airports and other places.
YB □ -12 pre-installed box-type substation (American), suitable for 10kV ring power supply, dual power supply or end point power supply system, as a substation, metering, compensation control protection device.
This product meets the following standards:
GB/T17467-1998 "High Voltage and Low Voltage Prefabricated Substation"
DL/T537-93 "Technical Conditions for Ordering 6-35kV Box Substation"
conditions of use
The altitude does not exceed 1000m;
● Ambient temperature: -35 ℃~ + 40 ℃;
Relative humidity: the daily average is not greater than 95 months average is not greater than 90%;
Installation place: no fire history, explosion hazard, chemical corrosive gas and well-ventilated place, the ground inclination is not more than 3 ".
Functions and Features
Fully insulated, fully sealed, free of maintenance, and reliable to ensure personal safety.
● Compact structure, volume is only 1/3-1/5 of the same capacity, low height;
It can be divided into boxes to avoid oil pollution in the transformer tank.
The high-pressure side is protected by double fuses, which greatly reduces costs.
● The ring network can be used, and it can also be used for end points. The cable head can be urgently plugged and unplugged when the load current is 200A;
● The box adopts honeycomb double-sandwich composite board, which has the function of temperature insulation and heat dissipation;
● The low voltage side is equipped with an electronic phase loss protector, which can quickly break the main inlet switch when an abnormal voltage occurs in the system;
High-pressure side oil-diffuse load switch or SF6 load switch, which can be electrically upgraded, laying the foundation for the realization of distribution network automation.
● Adopt oil-diffused S11 or better performance S13 series transformers.
