YBM series prefabricated substations combine high-voltage electrical equipment, transformer low-voltage electrical equipment, etc. into a compact complete set of power distribution devices. They are used in urban high-rise buildings, urban and rural buildings, residential areas, high-tech development zones, small and medium-sized factories, mining and oil fields, and Temporary construction electricity and other places are used to receive and distribute electric energy in the power distribution system.
Overview
YBM prefabricated substations have the characteristics of strong form factor, small size, compact structure, safe and reliable operation, easy maintenance, and mobility. Compared with conventional civil substations, the area of a box-type substation with the same capacity is usually only 1/10 to 1/5 of that of a conventional substation, which greatly reduces the design workload, construction volume, and construction costs. In the power distribution system, it can be used in the ring network power distribution system or in the dual power supply or radial terminal power distribution system. It is a new complete set of equipment currently used in the construction of urban and rural substations.
YBM prefabricated substation complies with the national standard "GB/T7467-1988 High Voltage/Low Voltage Prefabricated Substation".

Mechanical features
1. This product is composed of high-voltage power distribution device, transformer and low-voltage power distribution device connected, and is divided into three functional compartments, namely high-voltage room, transformer room and low-voltage room. The high-voltage and low-voltage rooms have complete functions. The high-voltage side power supply system can be arranged into various power supply modes such as ring network power supply, terminal power supply, dual power supply, etc. High-voltage metering components can also be installed to meet the needs of high-voltage metering. The transformer room can choose S9 , SC and other series of low-loss oil-immersed transformers or dry The transformer-type low-voltage room can adopt a panel or cabinet-mounted structure to form the power supply solution required by the user according to the user's requirements. It has multiple functions such as power distribution, lighting distribution, reactive power compensation, electric energy measurement and electricity measurement to meet the different needs of the user. requirements, and facilitate users' power supply management and improve power supply quality.
2. The high-pressure chamber has a compact and reasonable structure, and has a comprehensive interlocking function to prevent misoperation. When required by the user, the transformer can be equipped with tracks, which can facilitate entry and exit from the gates on both sides of the transformer room. Each room is equipped with automatic lighting devices. In addition, all the components selected for the high and low voltage rooms have reliable performance and are easy to operate, making the product safe, reliable and easy to maintain.
3. Adopt two methods of natural ventilation and forced ventilation. There are ventilation channels in the transformer room and high and low voltage rooms. The ventilation fan has 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. The material is made of colored steel plates and has anti-corrosion and heat insulation functions. And it has the conditions for long-term outdoor use, ensuring anti-corrosion, waterproof, dust-proof performance, long service life, and beautiful appearance.
