Product description
parameter

YB series compact prefabricated substation is to combine high-voltage electrical equipment, transformer, low-voltage electrical equipment and etc into a set of compact distribution facility, for receiving and distributing power in the distribution system. The substation has the features such as complete, small size, compact structure, safe and reliable operation, easy maintenance and mobility. Compared with the common civil type transformer substation, the packaged substation with the same capacity generally occupies just 1/10-1/5 land area, significantly reducing design and construction workload and construction cost. The packaged substation can be used in ring network distribution system, dual power source or radiation terminal distribution system; it is the new complete equipment for construction and restructuring of urban and rural substations.

 

The product is made by connection of high voltage distribution device, transformer and low voltage distribution device and is divided into three functional compartments, namely, high voltage compartment, transformer compartment and low voltage compartment. The high voltage compartment and low voltage compartment have complete functions. The primary power supply system at the side of high voltage can be arranged with multiple power supply modes such as ring network power supply, terminal power supply, dual power supply, and it can also be installed with high voltage metering elements to meet the requirement of high voltage measurement. The transformer compartment can be selected S11, S13 and other oil dipping transformer or SCB10, SCB11 dry type transformer; the transformer compartment is installed with automatic forced air cooling system and lighting system. According to the user's demand, panel or cabinet structure can be used in low voltage compartment to provide the power supply program required by user. There are several functions, such as power distribution, lighting distribution, reactive power compensation, power metering and power measurement, which can meet the different demands of users and facilitate the user's power supply management and improve power supply quality.

 

High-voltage compartment has reasonably compact structure and interlinking function that fully prevent wrong operation. Upon user's demand, a transformer may be set up tracks so that people can enter or exit from the gates at two sides of transformer compartment. In each compartment, there is an automatic lighting device; all elements used in high voltage and low voltage compartment are reliable and easy to operate, therefore, the devices can realize safe and reliable operation and easy maintenance.

 

Natural ventilation and forced ventilation are used to maintain good ventilation and cooling. Transformer compartment and low voltage compartment have airways, and fan is automatically turned on or off according to the set temperature by the temperature controller, thus the transformer can be operated in full load.

 

The box structure can prevent entry of rain or pollution and is made of special steel sheet or aluminum alloy sheet. It can be long-term outdoor use thanks to its anticorrosion, waterproof and dustproof performance. It has long service life and beautiful appearance.
