Can produce electrostatic with hatch container wall friction, these electrostatic need it is effective derive, to ensure hatch container and float element
Between equipotential link.
According to SH3046《Petrochemical industry vertical cylinder steel welds tank designs specification》Regulation:" when using non-gold
During the soft seal that category material is made, at least it is not less than 16mm using two sectional areas2Soft copper multiple twisted wire connection floating roof and tank skin.”
It is connected with floating roof by the length high more than tank, when floating roof liquid level is raised, the multiple twisted wire of soft copper is scattered in floating roof, due to wind rain
Beat and the influence of environment makes the multiple twisted wire of the soft copper easily corrode, thus there is potential safety hazard.Because soft copper conductor length is more long,
Therefore no matter float element is in any position, its resistance is all larger, so as to lose static conductive effect to a great extent.
In thunderstorm weather, between aerial powered cloud, all exist between powered cloud and peripheral facilities, between powered cloud and ground and put
Electric condition, these electric discharges can cause the acute variation of hatch container surroundings electric field.In order to reach the balance of electric field, hatch holds
The charge inducing in float element in device can release according to certain rules, and existing connect hatch container and float element 2
Braiding flexible circuit conductor is difficult to meet the immediate leakage of charge inducing, and transient potential will be formed between hatch container and float element
Difference.The caulking gum for being set between hatch container and float element in addition can also cause the electricity between float element and hatch container
Draw last breath edge, while the metal object on sealant tape, such as conducting strip, connecting bolt, metal sealing plate all have discharging condition, one
Denier they and potential difference and spacing between hatch container reaches discharging condition, and will discharge generation spark, the point as accident
Burning things which may cause a fire disaster.
