LPD -100/1000 Spark Gap Protector - Insulated Joint Protection Device for Buried Petroleum Pipelines

Advantages:

Fast Response: The spark gap protector responds at the nanosecond level, capable of reacting to overvoltage and generating spark discharge in an extremely short time.

High Current-Carrying Capacity: It can withstand large lightning currents or overcurrents, performing well in energy dissipation.

High Stability and Long Lifespan: The protector typically has a long service life and excellent stability, enabling long-term reliable operation in harsh electrical environments.

Explosion-Proof and Waterproof: Designed with a sealed enclosure, it effectively prevents arc leakage and offers outstanding explosion-proof and waterproof functionality.

Corrosion-Resistant Material: The enclosure material is corrosion-resistant, adaptable to various usage scenarios, and widely suitable for diverse environments.

Main Functions

Lightning Overvoltage Protection: When lightning strikes a line or equipment, the protector responds quickly, diverting the lightning current to the ground to protect electrical equipment from lightning surges.

Operational Overvoltage Protection: In power systems, operational overvoltages caused by switching operations, fault clearing, etc., can also damage electrical equipment. The spark gap protector rapidly generates spark discharge when these overvoltages reach a certain level, limiting voltage rise and ensuring the safe operation of electrical equipment.

Overvoltage Limiting and Energy Absorption: The protector can quickly limit overvoltage to a lower amplitude range and effectively absorb the energy generated by overvoltage.

Equipotential Bonding: In systems such as buildings, railways, and petrochemical plants, the spark gap protector can be used for equipotential bonding between two independent grounding bodies, ensuring that all parts of the system maintain the same potential during overvoltage events to prevent damage caused by potential differences.

Application Areas

Power Systems: Suitable for protecting various high-voltage electrical equipment in power systems, such as transformers, switchgear, surge arresters, and circuit breakers. It prevents damage from lightning or operational overvoltages, ensuring stable operation of the power system.

Oil and Gas Pipelines: Installed across the insulating flanges of oil and gas pipelines to prevent lightning or operational overvoltages from breaking down the insulating flanges. It limits pipeline overvoltage to a lower amplitude, avoiding potential harm to personnel in contact.

Buildings: Used in lightning protection grounding systems for buildings, connecting lightning protection devices and grounding bodies to achieve equipotential bonding. This prevents damage to personnel and equipment inside buildings due to excessive potential differences during lightning strikes.

Communication and Railway Systems: Protects communication equipment in base stations and communication rooms, as well as electrical equipment in railway systems, from damage caused by lightning and operational overvoltages.

Petrochemical and Steel Industries: Safeguards electrical equipment such as motors, distribution cabinets, and automated control systems in chemical plants, refineries, and steel mills, preventing equipment damage, fires, explosions, and other accidents triggered by overvoltages.
