Gas station lightning protection engineering design and construction plan, which was organized and summarized by the technical staff of Zhengzhou Leidi Electronic Engineering Co., Ltd.:
1. The tank should be grounded for lightning protection, and the grounding point should not be less than two.
2. Buried oil tanks should be electrically connected to the ground-exposed process piping and grounded.
3. The gas station's information system should use armored cables or wires to run through the steel pipe. Both ends of the metal sheath of the distribution cable and both ends of the protective steel pipe should be grounded.
4. Joint grounding devices for anti-static and anti-inductive lightning shall be provided at the beginning, end, and branch of oil pipelines laid on ground or in trenches, and the grounding resistance shall not be greater than 30Ω.
5. The gas tanker unloading site at the gas station shall be equipped with an antistatic grounding device for tanker unloading, and shall be equipped with an electrostatic grounding device capable of detecting the status of the crossover line and monitoring the grounding device.
6. Apply metal wires across the flanges on the oil pipelines in the explosion danger area, and the ends of the hoses. When the flange has not less than 5 connecting bolts, it may not be bridged in a non-corrosive environment.
7. The grounding resistance of anti-static grounding device should not exceed 100Ω.
8. When the stations and shelters within the gas station need to be protected against direct lightning strikes, lightning protection (net) protection should be used.
9. When connecting the first and the end of a distribution line of a gas station information system to an electronic device, an overvoltage (surge) protector that is compatible with the withstand voltage level of the electronic device should be installed.
10, 380/220V power supply and distribution system should adopt TN-S system, the cable metal sheath or cable metal protection tube of the power supply system should be grounded at both ends, and the power supply terminal of the power supply and distribution system should be installed to adapt to the pressure resistance level of the equipment. Overvoltage (surge) protector.
11. The lightning protection station, anti-static grounding, working grounding of electrical equipment, protective earthing, and grounding of information systems should share grounding devices. The grounding resistance should not exceed 4Ω.
12. Grounding resistance of lightning protection and grounding devices of oil tanks, LPG cylinders and CNG cylinders, grounding resistance of both ends of the metal sheath of the distribution cable and grounding devices at both ends of the protection pipe, when separate grounding devices are separately provided. Should not be greater than 10Ω; protective grounding resistance should not be greater than 4Ω; grounding resistance of grounding devices at the beginning, end, and branch of ground oil, LPG and natural gas pipelines should not exceed 30Ω.
