YB6 series prefabricated substations (also called American substations, hereinafter referred to as Meibian) are a combination of combined transformers, load switches and protective fuse devices for high-voltage power receiving parts, and metering and switches for low-voltage power distribution parts. The complete set of substation and distribution equipment is a new type of complete set of substation and distribution equipment developed by absorbing foreign advanced technology and combining with domestic actual conditions. Because of its small size, low investment, convenient operation, fast installation, and simple maintenance, Meibian has been widely used in domestic power distribution systems, especially in the construction and transformation of urban and rural power grids, and is widely used in industrial parks and residential communities. , Commercial centers and high-rise buildings. In addition to meeting the relevant standards of their respective components, this product also meets the relevant regulations of "GB/T17467-1998 High-Voltage/Low-Voltage Prefabricated Substations" and meets the technical conditions of this product.
Product Features: The structure is compact and reasonable, and the volume is small, which is only about one-third of the European-style box change of the same capacity; Fully sealed, fully insulated structure, no need to set up safety barriers, and reliable guarantee for personal safety; There are a variety of power supply schemes for users to choose from, which can adopt terminal power supply and realize ring network or dual power supply; S11 oil-immersed power transformer is adopted, which has low loss, low temperature rise and strong overload capacity; Double fuses (backup protection fuse + plug-in fuse) are used for protection, and the plug-in fuse fuse has the current and temperature dual sensitivity characteristics to ensure the safe and reliable operation of the product; The 200A cable connector can be plugged and unplugged under load, and can be operated as a load switch in an emergency. It also has the characteristics of an isolating switch. The winding adopts Dyn11 connection and the iron core adopts a three-phase four-column structure, so that the product can run under any asymmetric load, and the neutral point does not drift, the voltage is stable, the power supply quality is high, the cabinet heats up, the noise is low, and the lightning protection performance is good ; The cabinet adopts anti-corrosion design and special spray paint treatment, beautiful and novel, suitable for various environments, and achieve the effect of beautifying the city.
Environmental conditions for normal use
Altitude: not more than 1000 meters;
Ambient temperature: no higher than +40°C, no lower than -25°C, daily average temperature difference no more than 35°C, annual average temperature difference no more than 20°C;
The wind speed does not exceed 35m/s; There is no explosion hazard in the installation site, no chemical corrosion and severe vibration;

Product structure :The transformer part and the control cabinet part of the United States variation, of which the transformer part is a fully sealed structure, and the insulating oil can be two types of high ignition point oil or ordinary oil. The control cabinet is divided into a high-voltage room and a low-voltage room. The high-voltage room is equipped with: high-voltage cable plug, lightning arrester, load switch operating handle, non-excitation tap switch handle, plug-in fuse, pressure release valve, thermometer, pressure gauge, oil Position gauges, oil filling plugs, oil drain valves, etc., load switches, off-excitation tap changers, plug-in fuses, etc. are all immersed in transformer oil together with the transformer core. The high-voltage cable and the transformer are connected by elbow cable connectors. The low-voltage side can be installed with air circuit breakers, current transformers, as well as electric energy meters, ammeters and voltmeters, and output circuits and capacitance compensation devices can be configured according to user needs.
