YB-PRE box-type substation series (European box-type substation) Product Introduction
YB-type box-type substation, also known as European box-type substation, products in line with GB17467-1998 “high and low voltage pre-assembled substations” and IEC1330 and other standards, as a new type of power supply and distribution equipment, it has many advantages over the traditional civil substation. Because of its small size, small footprint, compact structure, easy to relocate, thus greatly shortening the cycle of infrastructure and footprint, but also reduces the infrastructure costs. At the same time, the box-type substation site installation is simple, rapid power supply, equipment maintenance is simple, no need for manned, especially it can be deep into the load center, to improve the quality of power supply to reduce power loss, enhance the reliability of power supply as well as power distribution network selection is very important. Box variable completes the transformation, distribution, transmission, metering, compensation, system control, protection and communication functions. YB-type substation by the high-voltage switchgear, low-voltage distribution panels, distribution transformers and the shell of the four parts of the combination, high-voltage is the air load switch, the transformer is a dry-type transformer or oil-immersed transformer. The box adopts good heat insulation and ventilation structure, beautiful appearance, good heat insulation performance, and the box is equipped with upper and lower ventilation duct, outdoor insulation on the transformer room and high and low voltage room caused by the temperature rise can be reduced to a low limit. The box should be equipped with temperature control forced ventilation device and sun temperature automatic control device. Each independent unit is equipped with perfect control, protection, charged display and lighting system.
YB-PRE box-type substation series (European box-type substation) Application Scope
It is suitable for small unattended substations with voltage 35KV and below, main transformer capacity 5000KVA and below, and is widely used in 10KV ring network system of urban industrial substation, 35KV substation of agricultural network and other occasions.
YB-PRE box-type substation series (European box variable) main function
It accomplishes the functions of power conversion, distribution, transmission, metering, compensation, system control, protection and communication.
YB-PRE box-type substation series (European box variable) main features
The primary and secondary equipment is pre-installed in a movable, fully enclosed, temperature self-control, anti-corrosion, moisture-proof and rust-proof box, which is only installed on the cement foundation when it arrives at the site. It is characterized by low investment, short construction period, small footprint and easy coordination with the environment.
