SZ11 33KV on load tap changing oil immersed transformer
SZ11 33KV on load tap changing oil immersed transformer
Detail

The transformer equipped with on-load tap-changing switch is called as On-load tap-changing Transformer.,has several tap joints are educed from transformer windingpassing through on-load tap-changing switch and change tapping location and itseffective number of windings in case of ensuring not to rupturing load currentand thus making use of changing transformer ratio to aim at unchangeable outputvoltage. Energy during changing and tapping process usually utilizes transitionresistance to absorb limitation cycle current.
