Product Description

 

Product Description

 

S11-M series fully sealed oil immersed power transformer by advantages of low loss, low noise and high efficiency, which can achieve good energy-saving effect and reduce pollution.   Compared with the ordinary oil immersed transformer, the fully sealed transformer cancels the oil conservator, and the change of oil volume is automatically adjusted and compensated by the elasticity of the corrugated sheet of the corrugated oil tank.   The transformer is isolated from the air, so as to prevent and slow down the deterioration of oil and insulation aging, enhance the operation reliability, and avoid maintenance in normal operation.

9.Altiude is not exceeding 1000m,ambient temperature not exceeding 40OC. If it can't meet such conditions,we will modulate parameters in accordance with standard.

Mainly Components:
The primary components of this advanced transformer include: the Oil Tank, Conservator, Buchholz Relay, Breather Unit, Oil Indicator, Temperature Detector, Pressure Relief Device, Thermal Relay, Radiator, and Bushing.
1. The oil tank is designed to immerse and cool the windings, ensuring optimal performance and efficiency.
2. This product complies with stringent IEC standards and is certified with CE/ISO, guaranteeing quality and reliability.
3. The design allows for easy monitoring and expansion during operation, facilitating the controlled increase and decrease of the oil's temperature.
4. The Buchholz relay is crucial when using a conservator tank, as it detects faults such as low oil levels or improper oil flow between the tank and the transformer.
5. The Breather Unit, containing silica gel, absorbs moisture effectively. It signals saturation by changing from blue to pink, indicating it can no longer absorb moisture.
6. The oil indicator provides precise measurements of oil levels within the conservatory unit, ensuring maintenance is timely.
7. The temperature detector meticulously monitors oil temperature. Should it reach critical levels, it will disconnect the transformer to prevent overheating.
8. The pressure relief device is engineered to reduce internal pressure, thus preventing any risk of transformer explosion.
9. The thermal relay acts as a precise indicator for the winding's temperature, offering vital data for safe operation.
10. Boasting a full galvanized coating, this component is highly resistant to rust, ensuring long-term durability.
11. The bushing is designed to seamlessly connect the internal windings of the transformer to an external electrical network, ensuring efficient energy transmission..

Oil Immersed Transformer Wiring Port:
High and low voltage wiring port with self locking nut.
Oil Level Measure Device:
Oil amount is clearly visble,red represents oil amount is
insufficient,blue represents normal.
Pressure Relief Valve:
Protect the oil tank from deformation or bursting.The water and air
outside the oil tank cannot enter the oil tank,and the inside of the
transformer will not be polluted by the air.
Off circuit Tap Changer:
It can be directly flxed on the cover or wall of the transformer,and can be tapped and replaced under no excitation state.
Gas Relay:
More sensitive sersing of changer in the internal gas of the transfomer to protect the transformer.
Oil Drain Valve:
Quick oil drain,reducing maintenance time,Convenient maintenance.

Energy-saving product energy-eficient secondary-class oil-immersed transformer is our company through theresearch and application of new materials, new technology and the combination of independent innovation andtechnology introduction, through the optimization and innovative design of the core and coll structure, to reduce no-loadoss and noise The purpose of self-developed products.
