Scope of application
The transformer can replace the transformer of silicon steel sheet iron core and is widely used in outdoor power distribution system.The large-scale operation of the product into the network can achieve good energy-saving effect and reduce the pollution to the atmosphere.This product is especially suitable for power shortage and load fluctuation in and dificult to carry out and insulation medium is not polluted by air.Therefore,it can operate in wet environment.It is the ideal distribution equipment in the vast distribution network of urban and rural areas.
Model meaning
Structural features
The transformer core is made of amorphous alloy strip,and the no-load loss is about 75%lower than that of the S9 transformer. At low voltage,copper foil coils are used to improve the transformer's ability to withstand short circuits.
Transformer connection group adopts Dyn11 to reduce the influence of harmonics on power grid and improve power supply quality. Vacuum oil injection can completely eliminate bubbles in the wire network to ensure stable absolute slow performance.
Conditions of use
The altitude does not exceed 1000 meters.
The ambient medium temperature is not higher than +40℃;Maximum average monthly temperature+30℃;Maximum annual average temperature +20℃;Minimum temperature:-25℃ .
Outdoors or indoors.
Transformers operating under special operating conditions are available according to user requirements.

Note 1:The product performance parameters of other capacities are determined by the manufacturer and the user through negotiation. Note 2:For single-phase transformers with any voltage of 2x(0.22-0.24)KV combination,when the low voltage is (0.22-0.24)KV,the capacity is halved (except when used in parallel).
Note 3:Other short circuit impedance values are determined by the user and the manufacturer in consultation.
Note 4:If the user needs,other loss values can also be selected.

Note 1:When the core is three-phase three-column,the YynO connection group can also be used according to the need.
Note 2:For three-phase transformers with a rated capacity of 500kVA and below,the load loss values above the slash line in the table apply to the Dyn11 connection group and the load loss values below the slash line apply to the YynO connection group.
Note 3:If the user needs,other loss values can be selected.
Note 4:According to the needs of users,other high-voltage tap range of three-phase transformers can be provided.
Environmentally friendly gas-insulated metal enclosed switchgear is the most commonly used three-phase intelligent gas-insulated AC cabinet and is widely used in various switchgear sets, with population concentration in the country, the power market must be supported, environmentally friendly gas-insulated switchgear will also grow with market development; market potential is yet to be tapped. At the same time, as the product integrates data collection and management, data processing and storage, online monitoring of switchgear, advanced analysis, and other multifunctions in one, network intelligent monitoring and management of the distribution network, so that the distribution network operates in a safe, reliable, high-quality, and efficient best state, to achieve remote monitoring, management, and control of the power system distribution network, to achieve network optimization, safe electricity use, power management, energy saving, and consumption reduction; at the same time, the system can be widely used in intelligent power distribution fields such as transportation, factories, hospitals, schools, buildings, residential areas, and commercial office buildings.
