With the rapid development of urban and rural power grids, distribution networks have turned to be dominated by cables. This shift results in a significant increase in the ground capacitor current, resulting in a reduction in recoverable faults when a single-phase ground fault occurs in the system. To address this challenge, the implementation of resistive grounding has become critical to adapt to the changing requirements of the power grid while reducing the insulation levels of power transmission and transformation equipment.
Resistive grounding has many benefits, including reducing investment in the entire power grid, being able to cut off faults, suppress resonant overvoltage, and enhance the safety and reliability of the power system. One of the key components for implementing resistance grounding is the grounding resistance cabinet, which plays an important role in ensuring the effectiveness of the grounding system.
Ground resistance cabinets are designed to provide a controlled path for fault current to flow to the ground, effectively limiting the voltage rise during a ground fault. By incorporating these cabinets into the grid infrastructure, the risk of electrical hazards and equipment damage can be significantly reduced. In addition, the use of ground resistance cabinets contributes to the overall stability and performance of the power system, ultimately improving its operating efficiency.
In the context of the continuous development of the power grid layout, the integration of ground resistance cabinets is crucial to ensure the safety and reliability of the distribution network. As the demand for efficient, sustainable power distribution continues to grow, the role of ground resistance cabinets in reducing potential risks and optimizing system performance becomes increasingly important.
In summary, the use of ground resistance cabinets helps solve the challenges posed by evolving grid structures. By adopting resistive grounding and using advanced grounding resistance cabinets, grid operators can effectively improve the safety, reliability and efficiency of the distribution network, ultimately contributing to the sustainable development of power infrastructure.
