Product Description of 2400kvar, 34kv 15 - stairs Shunt Reactor
Introduction
The 2400kvar, 34kv 15 - stairs Shunt Reactor is an essential Oil shunt Reactor designed to meet the complex needs of modern power systems. This reactor plays a crucial role in power grid operation by compensating for capacitive reactive power, improving power factor, and enhancing the stability and reliability of the electrical network.
Design and Construction
Oil - Filled Design
As an Oil shunt Reactor, it utilizes high - quality insulating oil to provide excellent insulation and cooling properties. The oil not only isolates the electrical components but also helps to dissipate heat generated during operation, ensuring long - term and stable performance. The oil tank is carefully designed with anti - corrosion treatment on its surface to protect the internal components from environmental factors.
15 - Stairs Structure
The 15 - stairs design allows for precise adjustment of the reactive power compensation. Each step can be independently controlled, enabling the reactor to adapt to different load conditions and power grid requirements. This stepped structure provides flexibility and fine - tuning capabilities, ensuring that the reactor can operate at the optimal state in various scenarios.
Technical Parameters (Based on IEC Standards)
Electrical Parameters
- Rated Reactive Power: 2400kvar. This value represents the amount of reactive power that the reactor can compensate under rated conditions, which is crucial for maintaining the power balance in the electrical network.
- Rated Voltage: 34kv. The reactor is designed to operate at a rated voltage of 34kv, which is suitable for medium - voltage power systems. It can effectively handle the electrical stress at this voltage level.
- Number of Steps: 15. The 15 - step design provides a wide range of reactive power adjustment options, allowing for more precise control of the compensation effect.
- Frequency: Usually, it is designed to operate at a frequency of 50Hz or 60Hz, depending on the local power grid requirements.
Insulation Parameters
- Insulation Level: In accordance with IEC standards, the reactor has a high - level insulation design to withstand over - voltage and electrical stress. The insulation materials used are carefully selected to ensure long - term insulation performance and prevent electrical breakdown.
- Partial Discharge: The partial discharge level of the reactor is strictly controlled within the limits specified by IEC standards. Low partial discharge indicates good insulation quality and reduces the risk of insulation degradation over time.
Temperature Rise Parameters
- Oil Temperature Rise: The maximum oil temperature rise under rated conditions is limited to ensure the proper functioning of the insulating oil and the internal components. IEC standards specify the allowable temperature rise to prevent overheating and damage to the reactor.
- Winding Temperature Rise: The winding temperature rise is also carefully monitored and controlled. The design of the reactor takes into account the heat dissipation of the windings to ensure that the temperature rise does not exceed the safe operating range.
Performance and Advantages
Reactive Power Compensation
The 2400kvar, 34kv 15 - stairs Shunt Reactor can effectively compensate for the capacitive reactive power in the power system. By adjusting the reactive power output through the 15 - step control, it can maintain a stable power factor, reduce line losses, and improve the efficiency of the power grid.
Stability and Reliability
As an Oil shunt Reactor, its oil - filled design and high - quality insulation materials provide excellent stability and reliability. The reactor can withstand various environmental conditions and electrical disturbances, ensuring continuous and safe operation in the power system.
Flexibility
The 15 - step design offers great flexibility in reactive power adjustment. It can be easily integrated into different power systems and can adapt to changes in load and grid conditions. This flexibility makes it suitable for a wide range of applications, from industrial power plants to urban power distribution networks.
Application
This Oil shunt Reactor is widely used in medium - voltage power systems, including power distribution substations, industrial plants, and large - scale commercial buildings. It can be used to improve the power quality of the electrical network, reduce voltage fluctuations, and enhance the overall efficiency of the power system.
In conclusion, the 2400kvar, 34kv 15 - stairs Shunt Reactor is a high - performance Oil shunt Reactor that meets the strict requirements of IEC standards. Its advanced design, excellent technical parameters, and reliable performance make it an ideal choice for reactive power compensation in modern power systems.
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.
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.
