Two types of explosion-proof lamps

The vast majority of explosion-proof lamps with electric shock protection type are Class I lamps, and only a few are Class II and Class III lamps. For example: all plastic explosion-proof lamps, explosion-proof flashlights. collect//./

**, classified according to the degree of protection of the enclosure: in order to prevent dust, solid foreign matter and water from entering the lamp cavity, touching or accumulating on live parts, causing flashover, short circuit or damage to electrical insulation, there are multiple enclosures The protection method plays a role in protecting electrical insulation. Use the characteristic letter 'IP' followed by two numbers to characterize the enclosure protection level. The first number indicates the ability to protect against people, solid foreign objects or dust. Divided into-level. Explosion-proof luminaire is a kind of sealed luminaire, its dust-proof ability is at least above grade. The first number indicates the ability to protect against water, which is divided into-grade.

**, according to the design of the support surface material classification: indoor explosion-proof lamps may be installed on many common combustible material surfaces, such as wooden walls and ceilings, they do not allow the temperature of the installation surface of the explosion-proof lamps to exceed the safe value. According to whether explosion-proof lamps can be directly installed on the surface of ordinary combustible materials, they can be divided into categories.
