Application Range of YB-PRE Series pad-mounted Substation (European Style pad mounted transformer)
Suitable for unmanned substations with a voltage level of 35KV and below, and main transformer capacity of 5000KVA and below. It is widely used in urban industrial substations, 10KV ring network systems, rural grid 35KV substations, and similar situations.
Product Introduction
The main functions of the YB-PRE Series pad-mounted substation, also known as the European Style Pad Mounted Transformer, include:
- Power Transformation: The substation is responsible for stepping down high voltage from the transmission network to lower voltages suitable for distribution to consumers.
- Distribution: It manages the distribution of electricity to various consumers or loads within a specified area.
- Transmission: The substation plays a role in the transmission of electricity from the main power grid to local distribution networks.
- Metering: It includes metering systems to measure the amount of electricity supplied to different consumers.
- Compensation: The substation may include equipment for power factor correction or reactive power compensation to improve the efficiency of the electrical supply.
- Control Systems: It incorporates control systems for monitoring and managing the operation of the substation and the distribution network.
- Protection Systems: The substation is equipped with protective devices and systems to safeguard the electrical equipment from faults and damage.
- Communication Systems: It may include communication systems for remote monitoring, control, and data exchange with the main control center or other substations.
These functions are integral to ensuring a reliable and efficient supply of electricity to end users while maintaining the integrity and stability of the power grid.
