Product Description of 2400KVAR 34KV Oil - Immersed Shunt Reactor
The 2400KVAR 34KV oil - immersed shunt reactor is a crucial piece of electrical equipment designed to meet the demanding requirements of modern power systems. As a key component in the electrical network, it plays an essential role in power factor correction, voltage control, and overall system stability.
Design and Structure
This shunt reactor is of an oil - immersed design. The oil serves multiple purposes. Firstly, it acts as an excellent insulator, preventing electrical breakdown and ensuring the safe operation of the reactor. Secondly, it functions as a coolant, dissipating the heat generated during the operation of the reactor to maintain an optimal temperature range. The reactor is enclosed in a robust and well - sealed tank, which protects the internal components from environmental factors such as moisture, dust, and mechanical damage.
The core of the shunt reactor is made of high - quality magnetic materials. These materials are carefully selected to minimize core losses and enhance the efficiency of the reactor. The winding is precisely wound around the core, following strict manufacturing standards to ensure uniform distribution of the magnetic field and electrical current.
Technical Parameters (Based on IEC Standards)
- Rated Apparent Power: The rated apparent power of this shunt reactor is 2400KVAR. This parameter indicates the capacity of the reactor to absorb reactive power in the electrical system. It is a crucial factor in determining the suitability of the reactor for a particular application.
- Rated Voltage: The rated voltage of the shunt reactor is 34KV. This is the voltage at which the reactor is designed to operate under normal conditions. It is important to ensure that the actual operating voltage does not deviate significantly from the rated voltage to avoid over - or under - stressing the reactor.
- Frequency: In accordance with IEC standards, the frequency of the shunt reactor is typically 50Hz or 60Hz, depending on the power grid requirements. The reactor is designed to operate stably at the specified frequency.
- Impedance: The impedance of the shunt reactor is carefully designed to match the electrical characteristics of the power system. It is an important parameter that affects the flow of reactive power and the overall performance of the system.
- Losses: The shunt reactor has both no - load losses and load losses. No - load losses mainly occur in the core due to hysteresis and eddy currents, while load losses are caused by the resistance of the winding. These losses are minimized through advanced design and high - quality materials to improve the energy efficiency of the reactor.
- Temperature Rise: The temperature rise of the shunt reactor is strictly controlled within the limits specified by IEC standards. This is to ensure the long - term reliability and safety of the reactor. The oil temperature and winding temperature are monitored during operation to prevent overheating.
Advantages of the Shunt Reactor
- Power Factor Improvement: By absorbing reactive power, the shunt reactor helps to improve the power factor of the electrical system. This reduces the overall power consumption and improves the efficiency of the power grid.
- Voltage Control: It plays a vital role in voltage control, especially in long - distance transmission lines and high - voltage systems. By adjusting the reactive power flow, the shunt reactor can stabilize the voltage and prevent voltage fluctuations.
- System Stability: The shunt reactor enhances the stability of the power system by reducing the risk of resonance and voltage instability. It helps to maintain a balanced electrical environment and ensures the reliable operation of other electrical equipment in the network.
In conclusion, the 2400KVAR 34KV oil - immersed shunt reactor is a high - performance electrical device that meets the strict requirements of IEC standards. Its reliable design, excellent technical parameters, and significant advantages make it an ideal choice for various power system applications. Whether it is used in large - scale power plants, substations, or industrial electrical systems, this shunt reactor can effectively contribute to the stable and efficient operation of the electrical network.
I.General Descriptions
BKS series oil type Shunt reactor is used to compensate the capacitive charging current of the grid, limit the rise of the system power frequency voltage and the operating overvoltage , so that reducing the insulation level of the system and ensure the reliable operation of the grid.With the continuous expansion of urban scale and the transformation of urban power grid, overhead line transmission is gradually replaced by underground cable, which makes the capacitive charging current of transmission network increase sharply. In order to reduce the rise of power frequency voltage and insulation level of the system, ensure the safe and reliable operation of the system and the power supply quality of the city's power grid,the Shunt Reactor is widely used in urban distribution network.
II.Structural features
1.The iron core is made of high-quality silicon steel sheet, wrapped with high-strength glass ribbon, thermally fixed, and fixed with special iron core curing paint, which can effectively reduce the vibration between iron core cakes and reduce the noise.
2.The coil is made of high quality paper wrapped copper wire. In order to ensure the safety and reliability of insulation structure, dot adhesive paper is used to prevent coil winding displacement.
3.The reactor adopts ripple oil tank with fully sealed structure. The thermal expansion and cold contraction of transformer oil are adjusted by the elasticity of ripple plate to ensure internal isolation from air, prolong service life and reduce maintenance.
