Datetime: 2023-05-23 10:27:00


LED explosion -proof lamps are a type of lighting fixture with explosion -proof properties and have a logo such as EX. The sealing performance of LED explosion -proof lamps, further protection measures, etc., have certain requirements for explosion -proof lamps. There are no LED explosion -proof lamps.
 
1. The types of explosion -proof lamps, levels, levels, and temperature groups see national standards.
 
2. It is divided into five main types of explosion -proof type, increased safety, positive pressure, non -spark type, and dust -proof explosion -proof type. It can also be combined or compounded by other explosion -proof types and the above -mentioned explosion -proof types. Special type.
 
3. The protection type of the anti -electrical shock can be divided into class Ⅰ, Ⅱ, and III. In order to prevent explosion -proof lamps from being easily touched by parts of the parts, the conductor of the human body shocked or different potentials touches the electric spark to ignite the explosive mixture.
 
Class A Ⅰ -On the basis of basic insulation, the non -charged conductive components that are not charged when they touch the normal work are connected to the protective ground conductor in a fixed line.
 
Class BI Ⅱ —— Use dual insulation or enhanced insulation as safety protection measures, without ground protection.
 
Class C Ⅲ -The safety voltage of the effective value is not greater than 50V, and it will not generate higher than this voltage value.
 
Class D0 -relied on basic insulation as security measures.
