Explosion-proof lamps refer to lamps that are used in dangerous places where flammable gases and dust exist, and can prevent arcs, sparks and high temperatures that may be generated inside the lamp from igniting flammable gases and dust in the surrounding environment, so as to meet explosion-proof requirements. Also known as explosion-proof lamps, explosion-proof lighting.
The selection, installation, use and maintenance of explosion-proof lamps are all indispensable links to ensure the long-term safety, reliability and efficient operation of explosion-proof lamps, and must be given full attention.
1 The selection personnel must understand the basic working principle of explosion-proof lamps and be familiar with explosion-proof signs.
2 Accurately select the explosion-proof category, type, level and temperature group of the lamps according to the level of the explosive hazardous location.
3 Understand the environmental conditions and work requirements, and reasonably choose explosion-proof lamps with various functions. For example, the enclosure protection level of explosion-proof lamps used outdoors is at least IP43. In places where color identification is required, high-pressure mercury lamps and high-pressure sodium lamps cannot be used for explosion-proof lamps, because these two light sources have poor color rendering.
4 Read the product instruction manual in detail to understand the product's performance, precautions and product limitations, and understand the contents of all signs of the product. If there is an "x" symbol after the explosion-proof certificate number, it means that the lamp has a specific applicable place. You should refer to the product instruction manual and nameplate to clarify the applicable place requirements.
The explosion source of the explosion-proof high bay light is far below the dangerous or far away from the installation position of the electrical circuit, and the explosion-proof circuit of the explosion-proof circuit is mainly composed of steel pipes or cable wiring.
Electrical installation wiring, as well as protection pipes, cables or pipes between different parts through walls or layers of explosive gas, non-combustible materials, should be tightly plugged.
In the framework of distribution lines, copper conductors or cables of explosive gas atmosphere hazard class 1 shall be used. Vibration should choose more copper conductor cable copper wire or multi-strand. I can't use aluminum core cables.
Wires or cables should be used for power lines within the range of risk levels 2 4 sections and above in explosion hazard areas, and lighting circuits exceeding 2.5 mm² may be used with aluminium conductors of wire or cable.
Insulated conductor cross-sections are selected to allow long-time delay current carrying capacity of cables and wires not less than 1.25 times the rated fuse and circuit breaker overcurrent trip setting. LED low-voltage squirrel-cage asynchronous motors are allowed to start and should not be less than 1.25 times the rated current load flow of the motor.
Mainly used in petrochemical plants, basins, outdoor or indoor equipment pipes, etc., instruments in the local lighting range, or areas such as pedestrian tunnels, the lighting configuration is generally 2-4 meters high, and the general requirement for lighting intensity is about 20 Lux. The requirements for lighting are uniform lighting, light, high brightness, and good performance (maintenance-free).
