Insulating rubber pad is more and more widely used. The function of the insulating rubber pad is to insulate the user from the road surface, so as to prevent the body and the road surface from closing the power circuit when the user touches the zero line of the live line, so as to maintain the life safety of the user. What specifications should the qualified insulating rubber mat meet? According to the current reasonable industry standard of insulating rubber mat "DL / t853-2004 insulating pad for live working" and "code for electrical safety work", the paving of insulating rubber mat should comply with the following requirements: distribution station, power station, high and low voltage distribution room, distribution box, diesel generator room of gas station and other electrical equipment
The width should not be less than 600mm, and the thickness should be decided according to the actual working voltage, not too low. 10-12mm thick insulating rubber pad shall be selected for the high and low voltage distribution room with working voltage of 35kV, 8mm thick insulating rubber pad shall be selected for 10kV, and 5mm thick insulating rubber pad shall be selected for the room with bottom voltage below 500V. According to the "gas station operator skill appraisal test set", the insulating rubber pad of gas station should be 10kV High voltage, and 8mm thick insulating rubber pad is suitable!
Natural selection of insulating rubber pad can not only look at the thickness, the key is the quality. Thin and thick do not pass the quality is no effect.
The insulation rubber pad of the machine should meet the following specifications:
The left and right surfaces should be leveled, and there should be no small round holes, gaps, partial protrusions, wounds, mixed conductive dirt, wrinkles, gaps, convex concave wavy lines, forging marks and other defects that damage the symmetry and smooth surface, so as to avoid reducing the compression specification and reducing the penetration time.
In the whole process of daily application, we should also pay attention to the maintenance of the insulating rubber pad. It can not be used in the wet and cold natural environment (it will damage its insulation). It is strictly forbidden to touch with oil, acid, alkali or other harmful substances, so as to prevent it from being eroded, which can not achieve the actual insulation effect. It is not allowed to touch pyrogen in close range to prevent sunlight (sunlight will accelerate the embrittlement of insulating rubber pad) and to avoid sharp objects hitting or scratching (in case of cracks). Otherwise, it is likely to lose its due insulation effect. Storage should be in a dry and naturally ventilated natural environment, avoiding pyrogen more than one meter.
It should be noted that the working shoes of gas station workers are antistatic shoes, which have excellent conductivity, and the effect is just the reverse of the shoes used by welders. Usually, we should pay more attention to the maintenance and pavement of the insulating rubber pad. After the actual operation of the distribution box, the distribution box and the diesel generator, we must ensure that all the feet stand on the insulating rubber pad.
