Description
Technical field
This utility model relates to high-tension switch cabinet technical field, a kind of insulation system for high-tension switch cabinet busbar.
Background technology
According to statistical data in 2012, the installed capacity of national grid is 8.83 hundred million kilowatts, the installed capacity of south electric network is 2.02 hundred million kilowatts, 6 times of considerations of installed capacity it are about by the total capacity of transformator, calculating with corresponding 1 the 35kV switch cubicle of every 5MVA transformator and 4 10kV switch cubicles, nationwide there are about 1,000,000 35kV switch cubicles and 4,000,000 10kV switch cubicles.Although China's high-tension switch cabinet market is huge, but owing to manufacturer is large number of, the switch cubicle that different manufacturers produces difference in terms of production technology, technical merit, production cost, product quality is caused to there is bigger difference, the situation that product is unsatisfactory for GB3906 and DL404 standard-required is the most universal, open the Insulation Problems of cabinet with height the most again the most prominent, be one of the factor that cabinet accident highlights the most that causes height to open.If high-voltage board generation discharge in insulation accident, its harm gently then causes device damage, heavy then cause large-area power-cuts, causes irretrievable loss to country.Therefore, the discharge in insulation hidden danger administering high-tension switch cabinet is an instant task.
Discharge mechanism according to high-tension switch cabinet: height opens cabinet room temperature cataclysm, the temperature difference is likely to result in more greatly the interior natural phenomena a kind of condensation occur of high-voltage cabinet.Owing to environmental pollution is day by day serious, industrial dust, dirt in air deposit on switch cubicle insulating part surface, after saliferous filth is moistened by condensation or moisture, form electrolyte, conductive capability is obviously enhanced, and Leakage Current significantly increases, thus causes the electric discharge flashover of switchgear.Condensation will directly influence the insulating properties of equipment in the cabinets such as bus, sleeve pipe, support insulator, cable and transformer that height opens in cabinet, make to become the arcing explosion accident within distribution high-voltage board more to take place frequently, thus reduce the electric power netting safe running level accessing these equipment, because site environment is moist, insulator contamination is heavier, cause phase spacing and relatively cabinet shell distance not enough, be also one of major reason of causing cabinet to discharge.
For solving the Insulation Problems that causes of wet environment, the highest open cabinet in busbar use heat-shrinkable T bush to carry out insulation processing.But, heat-shrinkable T bush also exists the inherent shortcoming being difficult to overcome, and is mainly reflected in:
(1) isomeric position such as bus joint cannot effectively be protected by heat-shrinkable T bush, it is impossible to accomplishes all insulation thoroughly；
(2) heat-shrinkable T bush itself does not have a hydrophobicity simultaneously, and therefore in the case of moist filth, its surface still takes place frequently electric discharge and creepage phenomenon, has a strong impact on height and opens the properly functioning of cabinet.
How to develop a kind of insulation system with high hydrophobic to have become as urgent need and solve the technical problem that.
