Study on the Technology of Non Contact on-load Automatic Capacity Regulating of the Distribution Transformer in Rural Power Network
摘要
Abstract
The load fluctuation in rural areas is high , and the load rate of transformer can not be in reasonable range .So the power distribution transformer according to the change of the load change automatically has important significance .The existing capacity regulating switch is a mechanical contact type , which is not suitable for frequent operation and low relia-bility .Therefor scheme of on-load automation capacity regulating which composite switch was used as capacity regulating switch was put forward .The composite switch was composed of a electronic switch and a mechanical type of contact switch .The overvoltage and overcurrent in the process of capacity regulating and its limitation are studied .Meanwhile ,the MATLAB/SIMULINK simulation software was used to simulate the on-load automatic capacity regulating transformer .The results showed that overvoltage and overcurrent would be generated when the capacity regulating switch was changed .And the overvoltage and overcurrent can be effectively suppressed by the appropriate size of butter resistance at the ends of the switch .关键词
