Lightning protection and anti-static grounding of the fuel system of diesel generators that Dongguan generators lease
power generation equipment: Ground steel oil storage tanks must be equipped with lightning protection grounding devices, and a closed ring grounding body should be buried around the tank body, and its grounding point should not be less than At two places, the distance between the grounding points along the circumference of the oil tank should not be greater than 30m. When the tank top is equipped with a lightning rod or the tank body is used as a lightning receptor, the resistance should not exceed 10; when the oil tank is only used for induction lightning protection grounding, the grounding resistance should not be greater than 30. Fixed top steel oil with a fire arrester on the ground Cans, when the thickness of the pre-board is greater than or equal to 4mm, there is no need to install lightning rods; when the temperature, liquid level and other measuring devices on the steel tank on the ground, Dongguan generator rental
should use cable or steel pipe wiring, cable sheath or distribution Wire steel pipes and tanks shall be electrically connected.
Grounding devices of anti-static and anti-inductive lightning shall be installed at the beginning, end, branch, and 200-300m of each straight section of oil pipelines laid on the ground or in trenches. The grounding resistance should not be greater than 30, and the grounding point should be located at the fixed pipe branch pier.
For direct lightning protection, lightning rods or belts should be installed on the parts of buildings and structures that are vulnerable to lightning strikes. When using a lightning protection strip, the distance from any point on the roof to the lightning protection strip should not be greater than 10cm, and the impact ground resistance of the anti-straight-ground device should not be greater than 3, and it should be connected to the grounding device of the electrical equipment leased by Dongguan Generator
and the buried metal pipeline; A ring-shaped grounding body should be formed around the building. The down conductors of the lightning protection device should not be less than 2 and the spacing should not be greater than 30m. In order to prevent lightning waves from invading buildings along low-voltage overhead lines, insulator iron feet should be connected to the lightning protection and grounding devices of electrical equipment at the household entrance. The overhead metal pipes entering the power station should be connected to the above-mentioned grounding device at the household entrance. http://ftfan.cn/
