BXMD series of explosion-proof distribution box explosion-proof power distribution box of a class. There are explosion-proof lighting distribution box, explosion-proof power distribution box, explosion-proof power distribution boxes. BXM (D) explosion-proof power distribution box for: petrochemical plants, oil platforms, gas stations, oil pump housing, transit stations and other flammable and explosive places for lighting. 1 and Zone 2 explosive atmosphere. 21 Zone 22 combustible dust. 1 Introduction With the rapid development of the petroleum, chemical, military, engineering, industrial, mining and other industries, explosion-proof power distribution box used in the production, storage, rescue more widely, more and more varieties. Explosive gas hazardous areas in how to prevent accidental explosion distribution box explosion happened has become a very important subject. Since the explosion-proof distribution box inevitably spark at work, once with explosive gas mixtures are produced or the scene of the encounter, it will lead to the explosion occurred, the State directly endanger the safety of life and property of citizens. Therefore, as the most widely used lighting box, it's proof technical problem had aroused widespread concern and attention. Scope 2 For 1, explosive gas mixtures dangerous places: Zone 1, Zone 2. 2, the gas mixture: ⅡA, ⅡB, ⅡC. 3, combustible dust Zone 20, 21, Area 22 4 temperature groups: T1 ~ T6. 5, explosion-proof mark: ExdeⅡBT6, * ExdeⅡCT6. 5. Summarized use venues such as indoor and outdoor workplaces, China's coal industry, PetroChina, Sinopec, CNOOC, electric power, metallurgy, railway, steel, shipbuilding, military, aerospace, public security and fire, chemical, government departments, venues, transportation and large enterprises need apply. NOTE: Please specify requirements ⅡC level. 3 explosion-proof distribution box is divided into major categories: explosion-proof lighting box, explosion-proof power boxes, explosion-proof control box, explosion-proof control cabinets, explosion-proof power distribution cabinets, explosion-proof control box, explosion-proof box, explosion-proof starting box, explosion-proof motor starters, explosion-proof soft starter , proof Frequency box, explosion-proof star delta starter box, explosion-proof auto-voltage starting box, magnetic starter explosion-proof box, explosion-proof electrical outlet box, mobile explosion-proof box, BMG proof distribution boxes, etc. 4 Use 1, according to the actual work site lighting needs, determine where and how to install the lamp, then press the lamp from the 220V power supply contacts to prepare the corresponding three core cable lengths (eg using pipe routing will be the introduction of three-core cable pipe to the lighting installation locations). 2, first remove the fixing screws on the wiring compartment, remove the terminal portion of the junction box; remove the seals and fittings (with set screws) from the box, and then click set into the cable; then, one end of each three-core cable indicates the access box "L", "N" and the ground at the compacted with pressure line card cable, and fixed with clamps, then tighten the fitting, clamping ring and tighten the screws from the side. 3, step 2 parts screwed pipe, installed from the side of the locking set screw, then light body along the rail into the junction box, and then tighten the screws on the tight panel. 4, and finally the other end of the three-core cable according to claim proof distribution box connected to 220V power supply. 5, replace the bulb, cut off the power, then remove with a hex wrench set screws on the housing, with a large screwdriver or other tool to loosen the lamp cover 6 laps, and then hand carefully remove the lamp cover slowly spin the old bulb replaced with a new lamp.
