YBM series box-type substation is constituted by high-voltage switchgear, power transformers, low voltage switchgear three parts together made to complete sets of outdoors oil change and distribution . he product have characteristics of strong complete set, small footprint, easy installation and maintenance, attractive appearance, strong weather resistance etc. This product is a frame structure with steel welded framework of Mongolia aluminum alloy plate and special paint coated, so it have a strong mechanical properties, weathering properties and corrosion resistance. Combined box-type substation use steel plate to divided cabinet inside into three separate small room, high-voltage room, transformer room and the low pressure chamber. Each lighting room automatically shut down when the door open. On the top of the modular box-type substation have the insulation layer. In the high-temperature alpine region, the inside temperature is easy to accumulate and make condensation which solution is increase cabinet hot insulation layer around cabinet. In order to keep inside temperature stability, there installed the automatic temperature control device in transformer room and the low pressure chamber. The box-type substation can effectively prevent the invasion of the small animals. Transformer maintenance can through the small removable car draw in and out. The box base on both sides with four corresponding hanging bolt that can be pulled out and push in, on both sides of the roof eaves with four same functions post supporting. The overall lifting and transporting of the modular box-type substation is made up of high voltage switch equipment, power transformers, low voltage switchgear three parts together that constitute the complete sets of outdoors oil transformation and distribution equipment. The product has characteristics of strong complete set, small footprint, easy installation and maintenance, attractive appearance, strong weather resistance etc.
The security and functionality profile of substation
1? A substation is made up of up and down tank and switchgear. High Voltage Switchgear tank with transformer oil separation to ensure the switch arc with a load operation will not affect the quality of transformer oil, the heat generated by the transformer is not caused significant effect on the temperature rise of the high voltage load switch. Loss is small, strong overload capacity that can be used for the ring network power supply, dual power supply or the terminal power supply system. So the power supply conversion is convenient and with reliable operation.
2? Box takes honeycomb sandwich composite panels to across the temperature and also with the cooling function, the technology is the latest development patent of our company.
3?Oil-immersed high voltage side load switch or SF6 load switch can do electric upgrade that to lay the foundation for the realization of the automation distribution network, high performance security, without exposed high voltage electrified body, fully enclosed, fully insulated structure and with a full range of protection functions .Complete products function can be equipped with more than 20 low-voltage circuit, compensation and metering functions. Can be use for the ring network and also be used for the electric terminal that conversion is very convenient, so improved the reliability of electricity supply. Box body takes the anti-corrosion design and special paint that can be widely used in a variety of harsh environments, such as storms and high pollution areas. Compared with the capacity of the traditional European-style box, the structure is more reasonable and low voltage room, transformer room, the hyperbaric chamber is not the head font layout. Structure is divided into front and rear two parts: the front is high and low-voltage operation interval which including high and low-voltage terminals, load switch operating handle, no-load voltage regulator section switch, plug-in fuses, oil level gauge etc; the rear are the injection tank and heat sink. Make the transformer wind resistance and iron core, put the high voltage load switch fuse in the transformer. Arrester is also takes oil-immersed metal oxide surge arresters. Transformer canceled the oil pillow, take the oil and air gap size constant design sealed fuel tank, and the radiator are exposed to the air, no heat. The low-voltage circuit breaker takes molded case circuit breaker as a main circuit breaker and the outlet breaker. Due to the simplified structure the floor area and substation and volume is greatly reduced, the required area is only 1/4 of the European same spec substation and the volume is only 1/5 ~ 1/3 of the European same spec substation. The series of this box volume changes is small, light weight, low noise, low loss, high reliability are widely used in the residential area, commercial center, railway stations, airports, factories, small and medium-sized enterprises, hospitals, schools, installation place etc.
Normal use environment
1?Ambient temperature: up to +45 ? ,lower limit -35?
2?Relative humidity is less than 90%
3?Altitude does not exceed 2500m
4?The ice cover is not more than 10mm
5?Wind speed does not exceed 34m / s,
6: Seismic intensity is not more than 8.
7; Install gradient is not more than 5 degrees
8?Free fire, free explosion hazard, no heavy pollution, no chemical corrosion and violent vibration of the place.If beyond the provisions of above-mentioned conditions, can go to consultation with our company
