In the actual use of portable lighting tower , we must also pay attention to explosion-proof. It also has explosion-proof characteristics. According to requirements, there are three types. explosion-proof type, increased safety type, and intrinsically safe type. Their explosion-proof principles are different .
The principle of explosion-proof type: under normal operation of the mobile lighting equipment, the parts that can generate spark arcs are placed in the flameproof enclosure. The flameproof enclosure can withstand the internal explosion pressure without damage, and can ensure that the internal flame gas spreads through the gap. The reduced energy is not enough to detonate the gas outside the shell.
The principle of the increased safety type: no arc, spark and dangerous high temperature will be generated during normal operation, and further protection measures will be taken in the structure to improve the safety and reliability of the mobile lighting
equipment.
The principle of intrinsic safety: under specified conditions, the electric spark and thermal effect generated by the circuit inside the equipment under normal operation or specified fault state cannot ignite explosive mixtures.
This is the main points of explosion-proof knowledge of portable lighting tower. For more relevant knowledge, you can continue to pay attention to our website.
