??? The use of explosion-proof lighting installation
The use of explosion-proof lights are suitable for a wide range of flammable and explosive places such as petrochemical plant, workshop and offshore oil platforms.
1, the performance characteristics:
Flameproof proof the highest level, reliable safety in explosive hazardous areas.
High-intensity gas discharge lamp as the light source, high luminous efficiency, the average service life of 10,000 hours or more.
Prisms tempered glass, non-glare, can effectively prevent the construction workers discomfort and fatigue.
The shading plate and precise light distribution design to improve the utilization of the optical efficiency, energy-saving effect.
Integrated full-tightness of the structure design and the latest surface treatment technology, beautiful appearance, easy installation, anti-rain, water spray, shell lamps never corrosion, rust, can be long-term in the harsh environment of the hot and humid and corrosive to use.
The housing selection of high-strength aluminum alloy, has a strong anti-collision and impact.
Pendant, wall-mounted variety of installation methods suitable for different lighting needs of the work site.
2, using the method:
1, according to the actual job site lighting needs, determine the location and manner of installation of lamps, and lamps to 220V power contact distance corresponding length Φ8 ~ 14mm core cable ready.
2 Remove the junction box on the side panel open / lock "logo from its box installed accessories, including seals, gaskets, and connectors (with set screws), such as lamps ceiling installation, Ceiling adapter (with set screws) and 3/4 inch adapter.
1) Wall-mounted: first lamp body bracket mounted on a wall or other support member (guarantee shading plate just above the bulb), and then the cable passes through the joints, gaskets, seals until the junction box (reserved a certain length of cable for easy wiring), and finally tighten the connector, tighten the set screws;
2) Tilt the boom-mounted: the connector through the cable, screwed steel pipe, tighten the set screws, and then passes through the cable gaskets, seals up to the junction box (set aside a certain length of cable to facilitate wiring) Light body and then spin into the connector, it is necessary to ensure the junction box wiring mouth down. Wired Step 3, by adjusting the relative position of the copper pipe fittings and, to ensure that the shielding plate in the top of the lamp n, and then tighten the set screw;
3) the vertical boom-installation: first connector through the cable, screwed steel pipe and tighten the set screws, and then passes through the cable gaskets, seals up to the junction box (set aside a certain length of cable convenient wiring ), then light body joints tighten, tighten the set screws;
4) Ceiling installation: 3/4 inch conversion connector screwed into the ceiling adapter, adapter into 3/4 inch adapter, set screws were tightened, and then through the cable, installed on the roof, and finally turn the cable through the gaskets, seals up to the junction box (set aside a certain length of cable to facilitate wiring), then the lamp body joints tighten, tighten the set screws;
3, one end of the three-core cable, respectively, access to a case "L", "N" and grounded identification at the platen clamping cable and then the cable, with clamps, and then mounted on the side panel, tighten the screws .
Finally, the other end of the three-core cable connected according to the explosion-proof requirements 220V power supply.
Replace the lamp, turn off the power, and then use a hex wrench to remove the set screws on the casing, with a large screwdriver or other tool, unscrew the lamp cover six laps, then hand lamp cover carefully and slowly remove the spin under the old bulb and replace with a new bulb.
Note: 1) non-charged open lamps; 2) Remove the lamp cover, careful detachment of the lamp and lamp shell.
Note:
1, when the lamps Canted must adjust the relative position of the pipe joint and, to ensure the shielding plate just above the bulb;
2, the installation and maintenance of lighting, you must cut off the power;
Use, the lamps surface has a certain temperature rise is normal, Transparency center temperature is higher, shall not touch;
4, we must use the company is equipped with electrical appliances;
Replace the lamp, you should use the same type of power bulb; if you change the bulb type or power, corresponding to replace the supporting ballast. (Source: Yixing Histon Electric Manufacturing Co., Ltd. Sales Department)
