May I ask if the button box can be placed in the room where hydrogen is released? ?
Can the electrical control cabinet for the equipment also be placed in the room where hydrogen is released? ?
It seems that the button box specifications don’t allow it to be placed in a room where hydrogen is released, right? ?
It is necessary to check the explosion-proof rating of the button box.
Use an explosion-proof button box; ordinary ones are not allowed.
If the explosion-proof rating of the button box meets the requirements for the classification of the explosion-proof area, then it is acceptable
What the people mentioned above said is correct; button boxes come in regular and explosion-proof versions. Even explosion-proof button boxes (devices) have specific explosion-proof ratings, and only those devices that meet the required explosion-proof standards can be installed and used in corresponding explosive environments.
But doesn’t the petrochemical regulation state that the power distribution room cannot be located in the same building as Class A areas?
No, an explosion-proof button box must be used.
The power distribution room and cabinets must be located outside the explosion-proof area; this is different from the explosion-proof button boxes we are talking about. Distribution cabinets and distribution rooms are not explosion-proof.
