Product Description

 

Capacities from 30kVA to 5500kVA
The oil-immersed transformer is an essential power equipment, prevalently utilized in the power system for its reliability and efficiency.

Basic Structure:
The oil-immersed transformer is comprised of several key components including the core, windings, oil tank, insulation bushings, radiators, and more. The core, constructed from laminated silicon steel sheets, minimizes eddy current losses, while the windings, made from copper or aluminum wires, facilitate voltage transformation through electromagnetic induction. The oil tank houses the transformer oil, which is vital for insulation, cooling, and heat dissipation. 
Working Principle:
Operating on the law of electromagnetic induction, the transformer alters AC voltage based on the turns ratio between the primary and secondary windings. When the primary winding is energized by an AC power source, an alternating magnetic flux is created in the core, thereby inducing the appropriate voltage in the secondary winding. 
Features:

1. Exceptional insulation performance: The transformer oil provides excellent insulation, significantly reducing the risk of short circuits between the windings and the core.
2. Superior heat dissipation: The oil's excellent fluidity rapidly dissipates heat generated during operation, ensuring the transformer remains within optimal temperature ranges.
3. Robust overload capacity: The transformer can endure short-term overloads, making it adaptable to unexpected power system conditions.

Application Fields:
Oil-immersed transformers are integral to power plants, substations, and industrial and mining enterprises, providing suitable voltage levels for power transmission, distribution, and utilization.

For instance, in large-scale industrial production, these transformers supply stable power to high-power equipment, while in urban grids, they convert transmission voltage to levels appropriate for residential and commercial use.
 

The digital transformer is based on intelligent sensors and the Internet of Things technology to achieve a full range of real-time and accurate perception of transformer operation status. At the same time, it has perfect protection, measurement, control and monitoring functions, realizing the integration of "management, control and operation" of transformers with "high efficiency, energy conservation, safety and environmental protection". In the future, it will provide reliable digital basic support for the realization of 3D model reproduction, fault expert diagnosis and early warning, energy Internet, big data and other business applications of transformers operating on the network.

 

 

Mainly Components:
The mainly parts of this transformer include Oil Tank, Conservator, Buchholz Relay, Breather Unit, Oil Indicator, Temperature Detector, Pressure Relief Device, Thermal Relay, Radiator, and Bushing.
1.  The oil tank is used to soak the windings by placing it in.
2.  Comply with IEC standards with CE/ISO certificates
3.  be easily contacted & enlarge throughout loading so that the temperature of the oil can be increased and decrease.
4.  Buchholz relay is used when a conservator tank is used.  Because it indicates errors like loss of oil once it goes low, improper flow of oil between the tank & transformer.
5.  Breather Unit includes silica gel that absorbs moisture in the oil.  It changes its color from blue color to pink color it is not capable to absorb moisture in the oil.
6.  The oil indicator indicates the level of the oil within the conservatory unit.
7.  The temperature detector monitors the temperature of the oil.  If the temperature of the oil increases to a certain level then the transformer will be disconnected from the service.
8.  Pressure relief device decreases the pressure within the transformer to avoid an explosion of the transformer.
9.  Thermal relay is used as an indicator for the temperature of the winding
10.  Full galvanized coating   no rust
11.  The bushing is used to connect the internal windings of the transformer with the help of an exterior electrical network.
The rated voltage can be customized as customers' requirements.
Features:

1. Voltage level: 10~35/0.4kV
2. Capacity: 30~3150kVA
3. With silicon steel laminated iron core, three-phase balance, no third harmonic.
4. Significant reduction in no-load loss and no-load current, with excellent energy saving effect.
5. Fully sealed oil tank and vacuum oil injection technology prevent oil aging, no oil leakage, and maintenance free.
6. External corrugated heat sink for oil tank, good heat dissipation and adjustable oil volume change, no need to install oil storage tank.
7. The high and low voltage leads are soft connected, equipped with pressure release valve and temperature measuring device to ensure the safe operation of the transformer.
8. High ignition point oil can be filled according to user's requirements, safer and more reliable, with a long service life.

Range of application:
Suitable for urban and rural power grid construction and renovation projects, as well as other distribution engineering projects, such as high-rise buildings, densely populated residential areas, important government agencies, airports, subways, stations, ports, petrochemicals, metallurgical mining, power plants, and places that require fire and explosion prevention.
