Products Description
Large power Transformers (LPTs) are the "heart" of the power system. They are responsible for boosting the low- and medium-voltage electrical energy generated by the power plant (such as 10kV~35kV) to ultra-high voltage suitable for long-distance transmission (such as 220kV, 500kV or even 1000kV), or at the client end, step down to the applicable voltage of the factory (10kV), business district (380V) or household (220V). In simple terms, it is like a "power dispatcher", ensuring that electrical energy flows efficiently and safely from power stations to millions of households and factories.
Why do you need it? Solve the core problem of long-distance transmission
When transmitting electrical energy, the lower the voltage, the greater the current, and the higher the line loss (waste of heat generation). LPTs solves this problem through the method of "boost transmission + buck use": the electrical energy of the power plant is first boosted to ultra-high voltage (the current is greatly reduced) to reduce transmission losses; the voltage is then lowered when approaching the user, which not only ensures the efficiency of long-distance transmission, but also ensures the safety of electricity consumption. It is a "stabilizer" for the stable operation of the power grid, and it is also a key adaptation equipment for new energy sources (such as wind power and photovoltaic) to be connected to the grid.
Advantages of our products: reliable, efficient and intelligent
The core materials are of high quality: high-permeability and low-loss silicon steel sheet (thickness is only 0.23~0.30mm) and high-purity copper wire are used to reduce energy loss; the winding has high mechanical strength and can withstand sudden short-circuit shocks (≥30 times the rated current).
Rigorous testing: Each unit has passed a full set of tests such as sudden short circuit and lightning impact before leaving the factory, which meets international standards (IEC 60076, IEEE C57) and has a life span of more than 30 years.
Energy saving and environmental protection: reduce the cost of the whole life cycle
Low-loss design: no-load loss (iron loss) is reduced by 15% to 25%, load loss (copper loss) is reduced by 10% to 20%, and the annual power saving is tens of thousands of degrees (for example, a 100MVA transformer saves 500,000 to 800,000 degrees per year).
Environmentally friendly insulation: optional natural ester insulation oil (biodegradable) or high ignition point mineral oil, no leakage of harmful substances, passed the EU RoHS and other certifications.
Wide capacity coverage: a single unit ranges from 63MVA (220kV) to 1500MVA (1000kV) to meet the needs of regional substations to UHV hub stations.
Full voltage level: supports mainstream voltages such as 220kV, 500kV, 750kV, and 1000kV, and specially optimizes long-distance transmission (such as the "West-to-East Transmission" project).
Intelligent operation and maintenance: early warning of failures
Real-time monitoring: integrated optical fiber temperature measurement (winding/core temperature), partial discharge monitoring (insulation aging early warning), oil chromatographic analysis (gas anomaly detection), accurate grasp of equipment status.
Digital management: access to SCADA system or Internet of Things platform, data cloud analysis, predict failures (such as winding deformation) 3 to 6 months in advance, and reduce unplanned downtime.
