Ground protection
Grounding protection is one of the most important safety measures in tower backup energy storage battery system. Reasonable grounding design can effectively prevent equipment damage and electric shock caused by electrical faults, lightning strikes, and static electricity accumulation, and ensure the safety and stability of the system during work.
Ground protection
Ground protection plays a crucial role in the tower backup energy storage battery system, which can effectively avoid the safety risks caused by electrical faults and lightning strikes. Reasonable grounding system design, strict grounding resistance control, and regular maintenance ensure the safety and stability of the device during operation, and ensure the long-term reliable operation of the energy storage system.
Specific information
Grounding system design
Independent grounding system: An independent grounding system is usually used to isolate the energy storage battery device from the grounding system of the building to prevent potential failures caused by a shared grounding system.
Grounding resistance control: When designing the grounding system, ensure that the grounding resistance meets the relevant standards (usually less than 1 ohms) to ensure that the current can quickly and safely flow into the ground when a fault occurs, avoiding damage to equipment and personnel.
Grounding wire selection: Choose wires that are thick enough and resistant to corrosion (such as copper or galvanized steel) to ensure that the wires will not be damaged or overheated when the current passes through them.
Security guarantee
Prevent electrical leakage: The design of the grounding system can effectively prevent the risk of electric shock caused by electrical leakage of the equipment and ensure the safety of the operator.
Current drainage: In the event of a short circuit or electrical failure, the grounding system can quickly guide the current into the ground, reducing the damage of the current to the device and protecting the key components of the energy storage battery.
Lightning protection: A good grounding design prevents lightning from directly hitting the device, reducing the risk of equipment damage or fire caused by lightning strikes.
Grounding electrical testing and monitoring
Grounding resistance test: After installation, test the grounding system to ensure that the grounding resistance meets standard requirements. If the resistance is too high, you need to take improvement measures, such as adding grounding electrodes or optimizing the grounding method.
Periodic inspection and maintenance: Check the grounding system periodically, especially after the device runs for a long time, to ensure that the ground connection is not corroded or loosened.
Fault alarm system: Install fault current monitoring device to detect the working status of the grounding system in real time. Once ground fault or abnormal current is found, alarm and repair measures are taken in time.
Ground grounding device
Grounding electrode: Grounding system usually uses grounding electrode, such as grounding rod, grounding network, etc., to introduce current to the ground. The choice of grounding electrode should be determined according to the soil resistivity and environmental conditions.
Grounding network design: In large-scale systems, the grounding network design can be used to combine multiple grounding electrodes into a network structure to improve the overall conductivity and stability of the grounding system.
