YB series prefabricated substation is a compact complete power distribution device that combines high-voltage electrical equipment, transformers, low-voltage electrical equipment, etc., it can be used in urban high-rise buildings, urban and rural buildings, residential quarters, high-tech development zones, small and medium-sized factories, mining and oil fields, and temporary construction power consumption and other places, as well as for receiving and distributing power in the power distribution system.
YB prefabricated substation has the characteristics of strong completeness, small size, compact structure, safe and reliable operation, convenient maintenance, and mobility. Compared with conventional civil substation, box type substation with the same capacity usually covers only 110-1/5 of the area of conventional substation, greatly reducing the design workload and construction amount, and reducing the construction cost. In the power distribution system, it can be used in the ring network power distribution system, as well as the dual power supply or radiation terminal power distribution system. It is a new complete set of equipment for the construction and transformation of urban and rural substations
YB prefabricated substation conforms to GB/T17467-1998 High Voltage Low Voltage Prefabricated Substation.
1. This product is composed of high-voltage power distribution device, transformer and low-voltage power distribution device. It is divided into three functional compartments, namely, high-voltage compartment, transformer compartment and low-voltage compartment. The high-voltage and low-voltage compartments have complete functions. The primary power supply system at the high-voltage side can be arranged into multiple power supply modes, such as looped network power supply, terminal power supply, dual source power supply, etc. It can also be equipped with high-voltage measuring elements to meet the needs of high-voltage metering. S9, SC and other series of low loss oil immersed transformers or dry-type transformers can be selected for the transformer room; According to the user's requirements, the low-voltage room can adopt panel or cabinet mounted structure to form the power supply scheme required by the user. It has multiple functions such as power distribution, lighting distribution, reactive power compensation, electric energy metering and electricity measurement to meet the user's different requirements. It is also convenient for users to manage power supply and improve power supply quality.
2. The high-voltage chamber has a compact and reasonable structure, and has a comprehensive anti misoperation linkage function. When required by the user, the transformer can be equipped with rails to facilitate access from the gates on both sides of the transformer room. All rooms are equipped with automatic lighting devices. In addition, all elements selected for high and low voltage rooms are reliable in performance and easy to operate, making the product safe and reliable in operation and easy to maintain.
3. Natural ventilation and forced ventilation are adopted. The transformer room and high and low voltage rooms are equipped with ventilation ducts, and the exhaust fan is equipped with a temperature control device that can automatically start and close according to the set temperature to ensure the normal operation of the transformer.
4. The box structure can prevent rainwater and dirt from entering, and the materials are made of color steel plates with anti-corrosion and thermal insulation functions. It has the conditions for long-term outdoor use to ensure anti-corrosion, waterproof and dust-proof performance, long service life and beautiful appearance.
