S11-M-ZT Type intelligent load adjustable capacity transformer- Oil-immersed Transformer

The intelligent load justable-capacity transformer has two large or small capacity tappositions，and can automatically adjust capacity operation without power failure according to the change of load When the load islighter and closest on on-load.the transformer adjusts the large capacity to small capacity to work. Both greatly reduce the no-load loss and avoid manual operation without power failure.and save the energy.The product issuitable to the rural power grids with load greatly changed in season.to residential area，street lamps，business district，part-time industrial zone and sucker rod pumping variable with greatly changed in day and night，and also suitable to greatly load change of 35K0v electric transformer.
Intelligent load adjustable-capacity transformer developed by our company have many patents，mainly made up transformer，adjustable-capacity switch，controlbox installed
loaded justable-capacity control.The data saving，remote communication.remote control.remote regulating，telemetry，intelligent，network.reactive power compensation control,guard against the function，and greatly difference with the traditional roll core,amorphous transformer.

T0.5 is electricity prices, RMB/(Kwh). 8600, 2200 Respectively are transformer non-load all year, equivalent load (load factor 0.5) Number of hours According to the related performance indicator, to calculated annual operation cost of the S11-M-ZT type intelligent load adjustable-capacity transformer and S11 Ordinary three-phase oiled type distribution transformer. Assume that the load capacitor transformer works in a large capacitor within 3 months of one year, and in a small capacitor within 9 months. According to the distribution transformer-related specification to calculate detailed data as form 3

The load adjustable-capacity transformer is adapted to the Substation field development towards energy saving, intelligence, high efficiency, and reliable
power supply quality. it can automatically change the terminal distribution transformer rated output capacity efficiency by following the load change. Timely and proper keeping of the power supply, greatly reduces the transformer non-load loss by 40%~50%, improves the grid power factor, reduces reactive components in distribution net and network loss and electricity capacitor, and opens a new way to develop an energy-saving distribution network, to the society to bring good economic benefit.

Form2 Compared opeartion cost between S11-M-ZT type intelligent load adjustable- capacity transformer and S11 type distribution transformer

Compared operation cost between S11-M-ZT type intelligent load adjustable-capacitytransformer and S11 type distribution transformer, Annual operation cost average re-duce 51%,cut down the installation fee than lashtransformer.The more investment ofS11-M-ZT type intelligent load adjustable-capacity transformer can recycle in threeyears.
