Description

technical field [0001] The invention relates to the technical field of leakage plugging of electric power equipment, in particular to a construction process of an acrylic adhesive for plugging leakage of electric power equipment under low temperature conditions. Background technique [0002] Oil leakage and gas leakage of power equipment in the operation of substations are common. If the oil leakage and gas leakage of equipment are not dealt with effectively in time, the leakage part will easily adhere to a large area of ​​oil pollution or leak a large amount of harmful gas sulfur hexafluoride. , not only affects the appearance of the equipment itself, the insulation of the equipment decreases, and even causes equipment power outages due to the lack of insulating medium in the equipment, which directly affects the safe operation of the substation equipment and the reliability and safety of the power supply, and also affects the normal and safe operation of the system power gr...

AI Technical Summary

Problems solved by technology

[0002] Oil leakage and air leakage are common occurrences in the operation of power equipment in substations. If the oil leakage and air leakage of the equipment are not promptly and effectively dealt with, the leakage parts are likely to adhere to a large area of ​​oil pollution or leak a large amount of harmful gas sulfur hexafluoride , which not only affects the appearance of the equipment itself, but also reduces the insulation of the equipment, and even causes a power outage of the equipment due to the lack of insulating medium of the equipment, which directly affects the safe operation of the substation equipment and the reliability and safety of the power supply. Therefore, it is very urgent to deal with oil leakage and air leakage of equipment thoroughly and effectively as soon as possible.

[0003] Most of the plugging adhesives for power equipment are acrylic materials. Due to the characteristics of acrylic materials, acrylic adhesives have the characteristics of rapid curing at room temperature 25 ° C. Generally, they start to cure within 5 minutes, basically cure within 1 hour, and have the highest strength after 24 hours; but at low temperatures (low temperature) at 10°C), the acrylic adhesive cures extremely slowly, has poor fluidity and low strength, and cannot meet the requirements of rapid plugging of electrical equipment

And the leakage position of the power equipment is divided into the surface position of the equipment and the flange position of the connecting pipe of the power equipment, especially the leakage position of the flange of the power equipment will have uneven sizing, which will affect the plugging effect

[0004] When the existing acrylic adhesive used for leakage plugging of electric power equipment is constructed under low temperature conditions, the plugging adhesive is manually heated back and forth with a high-power blower heating device, and the heating time is as long as several hours; therefore, the plugging adhesive is directly cured at low temperature and cured It takes a long time to increase the plugging construction time, which cannot meet the needs of fast plugging; using a high-power blower heating device for heating and curing has defects such as uneven heating and heavy workload
