The DGS18/127Y (B) mining flameproof fluorescent lamps ● the scope and purpose: DGS18/127Y (B) mine flameproof fluorescent lamps apply to gas and coal dust explosion hazard mine, available-for-yard, mechanical and electrical caverns central substation, roadway transportation, pumping stations and other places lighting purposes. This product is in accordance with GB3836-2000 "for explosive gas atmospheres" coal mine explosion-proof lamps and other relevant standards for electrical equipment and MT221-2005 design, manufacture, inspection. ● Model and meaning: ● Main features: 1, Lamp quality pure rare earth trichromatic phosphor, high luminous efficiency, low light decay, energy saving, the average life expectancy of not less than 6000 hours. 2, the lamp structure is novel, unique, easy to open, the lamp housing three-cavity of the Mouth QSP door connections, wiring, replace the ballast and lamp replacement glass tube can be used alone operation is complete, the installation and maintenance easier, faster and convenient. 3, light weight, small size, electrostatic spraying the surface of the light, strong adhesion, appearance, strong corrosion resistance. The main technical parameters: Model proof mark Rated voltage V Rated Power (W) illumination Lx introduced the cable specifications mm Weight Kg Dimensions L × W × H DGS18/127Y (B) ExdI 127 18 ≥ 10 ?7 to ?13 3.4 800 × 96 × 111 ● Architectural Overview: Lighting upper housing group, in the case group and the lower housing group composed of three parts. On the housing group built terminals and security cover Remove the safety cover can be wiring; equipped with ballast and lamp holder groups in the housing group, lamp holder group has a rotating pass, power devices; shell The peer group consists of a glass tube, metal protective cover and lower housing; housing is aluminum alloy die-casting, processing; connection of the three housing groups using only the mouth QSP door, installed between the housing group AUTO POWER rotated 90 degrees, rotated 90 degrees to open the automatic power-off of the shell; wiring, replace the ballast or lamp replacement without having to remove other parts of the glass tube, simply rotate the upper housing and housing or housing and lower housing 90 degrees, you can separate the wiring, replace the ballast or lamp replacement, glass, installation and maintenance is extremely convenient.
