ZD-PSACard tube type human body static eliminator(Intrinsically safe)
ZD-PSACard tube type human body static eliminator(Intrinsically safe)It is a human body static electricity removal device specially designed for the top of the oil storage tank, and is equipped with a sampling rope grounding terminal. Usually, pipe clamps are used to bind and install on the tank top fence. The touch ball also uses“Electrostatic subconductor”The material, slowly releases the static electricity of the human body, eliminates the hidden danger of static electricity, and meets the requirements of the CNPC standard for the intrinsically safe human body static electricity removal device, and the amount of charge transfer is less than 0.1μC. Whether the product has an alarm function is selected by the customer according to the requirements of use. In order to avoid drilling holes on the top of the tank, the grounding wire of the ZD-PSA human body electrostatic discharge device can be installed in a tube type, a card plate type, and a binding type, and they are all equipped with a paint-breaking thimble. It can be flexibly selected according to the usage conditions of the tank top. |
Use occasion(Refer to China National Petroleum Corporation Standards): |
Q/SY1431-2011"Anti-static safety technical specifications"-China National Petroleum Corporation corporate standards Article 4.4: Outside the door of the pump room, the entrance of the escalator of the oil tank, and the sampling port of the oil tank(Not less than 1.5m away from the sampling port), At the entrance of the escalator and suspension ladder of the operating platform in the loading and unloading operation area, the entrance of the installation area, the sampling port of the installation area, the entrance of the dock, and the oil discharge port of the gas station(Not less than 1.5m away from the oil discharge port)Intrinsically safe human body static eliminators should be installed in hazardous workplaces.The charge transfer amount of the intrinsically safe human body static eliminator shall not be greater than 0.1μC.Intrinsically safe human body static eliminators should be tested by qualified testing units, and allowed to be used on site after being qualified. |
Performance characteristics: |
1. The touch ball is made of electrostatic sub-conductor material, which will not produce electric sparks; 2, The product height and installation method can be customized according to requirements; 3、According to requirements, whether to provide sound and light alarm function; 4, Standard 1 meter grounding wire. |
