Neutral point reactor
The main function of a neutral point reactor is to limit the current received by the neutral point in the event of a ground fault in the power system, in order to prevent damage to other system components. It can effectively prevent the voltage rise between the neutral point and the external ground wire when a grounding fault occurs, thereby reducing damage to other system components. In addition, neutral point reactors can effectively limit the current at the neutral point in the event of multiphase faults, to prevent damage to other system components.
Neutral point reactors can also reduce the neutral point potential of transformers, thereby reducing potential noise interference related to simulated ground. It can improve the current distribution characteristics of transformers, thereby stabilizing the system current and reducing errors. In addition, neutral point inductors can also improve the short-circuit protection capability of power systems, ensuring system safety and reliability in the event of faults.
The combination of neutral point reactor and three-phase parallel reactor can compensate for phase to phase capacitance and phase to ground capacitance, limit overvoltage, eliminate latent current, and ensure the normal operation of single-phase automatic reclosing of the line. It also limits the resonant overvoltage when the reactor is not fully open, as non full phase opening is a resonant process that may generate a high resonant voltage.
In summary, the role of a neutral point reactor includes limiting the excessive growth of ground fault current, ensuring the safety of electrical equipment and personnel, improving the quality of system ground voltage, reducing fault range, improving system reliability, compensating for reactive power in the power grid, and increasing power factor.
The advantages of dry-type air-core reactor
1.High mechanical strength to withstand elevated short circuit forces.
2.Isothermal design method which ensures windings in all layers are the same with respect to the temperature rise.
3.Low noise level for noise sensitive applications.
4.Low eddy-current loss.The winding is wound in parallel with small diameter aluminum (copper) conductor of multiple dielectric layers, greatly reduce eddy current loss.
5.Epoxy impregnated fiberglass encapsulated construction.
6.Reasonable insulation structure, high reliability of inter-turn insulation.
7.Surface treatment for protection against UV radiation and pollution.
8.Minimum maintenance requirements and environmentally friendly.
9.All design are based on IEC, GB, JB standard.
