Product Introduction
In modern power systems, ensuring the safe and stable operation of the power grid is crucial. Neutral Grounding Resistor Cabinets, as key components of power systems, play an indispensable role. They are primarily used to connect a specific resistor in series between the grid's neutral point and ground, thereby optimizing the system's performance.

Product Features
Targeted and comprehensive protection: Suitable for low- or medium-resistance grounding at the neutral point. When a single-phase ground fault occurs, the system immediately trips and disconnects the faulty line, with overvoltages limited to 2.6 times the phase voltage, effectively protecting system equipment.
Compact design for easy installation: The Z-type grounding transformer (installed if a neutral point lead is not available), resistors, current transformers, and other equipment are integrated into a closed metal cabinet. Optional disconnect switches are available as a complete set, resulting in a neat layout and easy installation, commissioning, and maintenance.
Carefully selected materials for reliable quality: The grounding transformer utilizes a high-quality dry-type transformer with a "Z"-shaped primary winding. Resistors are made of stainless steel alloys, nickel-chromium alloys, and other materials, offering high conductivity, strong current carrying capacity, high temperature resistance (up to 1600°C), stable resistance, and flameproof and explosion-proof properties.
Comprehensive monitoring functions with analog output: Equipped with a current transformer and an operation recorder, it monitors neutral point unbalanced current during normal operation, records the number of fault operations, and provides analog output. Supports the installation of special lightning arresters and measurement and control protection devices to meet diverse monitoring and protection needs.
Application Scenarios
Power plants and substations:
Widely used in medium-voltage power grids ranging from 6kV to 35kV, particularly in systems primarily powered by cable. In these scenarios, Neutral Grounding Resistor Cabinets can effectively reduce the risk of fires caused by ground faults and ensure stable power output.
Industrial and mining enterprises:
For industries such as metallurgy and petrochemicals that require extremely reliable power supply, Neutral Grounding Resistor Cabinets can reduce the probability of equipment damage caused by ground faults, avoid production interruptions, and ensure continuous and stable production.
Urban distribution networks:
Especially in distribution networks with distributed power sources, resistance grounding is compatible with arc suppression coils, improving system flexibility and better adapting to changes in urban power demand.
