Iron and steel 110kV power transmission and transformation equipment installed in the open air, long-term working state, the dust in the environment is deposited on the outer insulation surface to form a layer of filth, the dirt layer contains metal particles, oil, dust and moisture-soluble salts, acids, alkalis and other substances, when encountering fog, dew and drizzle and other conditions, the conductivity increases, the insulation performance decreases, and it is easy to leakage, pollution flashover and other phenomena. In addition, the hazards of pollution to equipment include the following three:
1. The metal surface is affected by the action of oxygen in the air, which will generate a layer of oxide, which will cause the contact resistance to rise, and then cause the contact temperature to rise, which is easy to cause flashover.
2. Due to the electrostatic action near the equipment, the dust is polarized or even ionized, adsorbed on the surface of the charged body, and the polarized dust extends to a certain extent, which is easy to cause discharge. 3. The contact is polluted by dust or other substances, which causes the resistance to increase, and the Joule heating increases, which causes a disaster in severe cases.
Shihua Zhongke insulation maintenance live cleaning technology can use high insulation, non-combustible, volatile, environmentally friendly and other characteristics of cleaning agents for the operation of electricity, electrical and electronic equipment under the premise of "no power outage, no stop operation", and the professional and technical team of Shihua Zhongke uses special equipment and tools to follow specific operating procedures for operation.
Shihua Zhongke live cleaning technology has the following advantages.
1) Technical advantages.
1. Wide range of applications 2. Easy and fast operation.
4. High cleanliness, fast and thorough cleaning 5. When the air humidity is human, the cleaning agent can quickly remove the moisture on the electrical equipment.
6. The cleaning agent is neutral, especially toxic and harmless, and all volatilizes within 1-2 hours after contact with the air, without residue, so there is no corrosion to the equipment, no removal to the human body, and no pollution to the environment.
2) Benefit analysis.
1. Extend the service life of the equipment for 3-5 years.
2. Save electricity consumption.
3. Reduce the number of repairs and save maintenance costs.
4. Avoid accidents.
5. Avoid losses caused by power outages
Shihua Zhongke professional technical team this week in the steel 110kV live facilities for live cleaning, after cleaning, after evaluation, the live cleaning agent forms a semi-permanent protective film, with water repellent, mildew resistance, improve insulation value, oxidation and other protective effects on the equipment, eliminate the external insulation leakage current, so that the power equipment to restore its original design safety performance level.
Enterprises should establish a correct new concept of equipment maintenance, clear flow maintenance can play a role in the whole maintenance work in advance, active maintenance, eliminate hidden dangers in the bud, and completely eliminate the occurrence of accidents such as pollution flashover. Insulation maintenance live cleaning can change the past passive maintenance to active maintenance, surface maintenance to deep cleaning maintenance, and local maintenance to system maintenance.
