BXW series box-type substation
BXW series prefabricated box-type substation is an outdoor power distribution complete set composed of high-voltage switchgear, power transformer and low-voltage switchgear.
The product has the characteristics of a strong complete set, small footprint, small investment, convenient installation and maintenance, beautiful appearance, and strong weather resistance.
Features:
The frame of the BXW prefabricated box-type substation (European-style box-type substation) is a steel structure, which is welded with section steel.
The frame is covered with an aluminum alloy plate and coated with a special paint layer. It has strong mechanical properties, weather resistance, and corrosion resistance.
The combined (box type) substation has an integral structure, and the box is divided into three relatively independent chambers by steel plates, namely, the high-voltage chamber, the transformer chamber, and the low-voltage chamber.
The lighting of each room is automatically turned on with the opening of the door. There is a heat insulation layer on the top and around the box body, and the inside is equipped with a temperature and humidity control device, which can adapt to severe climate changes in high-temperature and high-pressure areas.
In order to stabilize the temperature in the box, prevent internal condensation, prolong the service life of the equipment, and improve the operation of the box substation Stability, and reliability.
The transformer adopts low loss, low-temperature rise, low noise, fully sealed and maintenance-free oil-immersed or epoxy resin insulated dry-type transformer, which fully embodies energy saving and environmental protection, and the actual operation meets the requirements of short-term full load and overload.
The high-voltage unit is a combination of high-voltage switch cabinets of various schemes. Including incoming and outgoing line cabinets, and metering cabinets. Modular design, reserved distribution network automation interface, can realize remote opening and closing operations of circuit breaker switches. Realize current, voltage, active power, reactive power, power factor, active and reactive power Remote collection and uploading of power and other parameters.
The low-voltage unit is a combination of low-voltage switches of various schemes.
Including metering cabinets, main circuit breaker incoming cabinets, low-voltage feeder cabinets, and capacitor compensation cabinets, which can realize low-voltage power distribution and overload and short-circuit protection, and select high-voltage circuit breakers to meet users' requirements for dynamic and thermal stability of switching currents.
The low-voltage metering unit adopts a high-precision electric energy meter. It can realize accurate metering of electric energy and has a communication function, which can realize remote meter readings.
The box-type substation is equipped with an automatic capacitance compensation device, which can compensate for the reactive power capacity of the system in time, increase the capacity of the transformer, increase the voltage of the low-voltage line, and ensure the quality of power supply for users.
