1. Divided into explosion -proof explosion -proof light -proof, increased explosion -proof lights, positive pressure explosion -proof lights, flame -free explosion -proof lights and smoke explosion -proof -proof -proof light -proof types. All kinds of explosion -proof forms are compounded or unique and unique.

2. According to the maintenance of safe electricity maintenance, it can be divided into class Ⅰ, Ⅱ, and III. Safe electricity maintenance is to prevent explosion -proof lamp cases easily touched parts of the parts, so that the conductors with electric shock accidents or different potentials are touched, causing spark discharge to ignite flammable compounds.

Class A Ⅰ -Basically, in the basics of the basic insulation layer, the electrical conductivity of the conductive electrical components that are not touched when it is easy to touch is connected to the ground -protective electrical conductor in a fixed and indifferent route.

Class BI Ⅱ — Use a two -way insulation layer or improve the insulating layer as a security guarantee measure, without protecting ground.

Class C Ⅲ -Safe voltage with an effective value of not exceeding 50V, and it is not easy to cause the voltage value higher than this work.

Class D0 -only with the help of the basic insulation layer as a security guarantee measure.

Most explosion -proof lamp safety and electricity maintenance forms are Class I lighting fixtures, and only a few can only be class Ⅱ and III lighting fixtures. For example: full -plastic explosion -proof lamps, explosion -proof flashlights.

3. Division according to the safety protection level of the case: in order to safely protect floating dust, solid dirty things, and water into the lamp cavity, touch or accumulate on the inductive charging component For the risks, there are various shell safety protection methods that have the effect of maintaining electrical equipment insulation layers. After using the characteristics of the English letters "IP", it is qualitatively analyzed the protection level of the shell with two large numbers. The first large number expression has the ability to protect the safe protection of people, solid dirty things, or floating dust. Divided into level 0-6. Explosion -proof lamps are a sealing lighting lamps. Its anti -decoration work ability is at least about 4 levels. The second large number expresses the ability to protect the safety of water, divided into level 0-8.

4. English design according to the support point of light design: explosion -proof lamps in the room will be installed on many surface layers of general flammable raw materials, such as wooden walls and ceiling ceiling. Label value. Whether the explosion -proof lamps can be installed immediately on the surface layer of general flammable raw materials can be divided into 2 categories. One is suitable for lighting lamps installed on non -flammable surfaces. Another type is a lighting lamps suitable for the surface layer of general flammable raw materials.
