S11/S13 series oil immersed distribution transformers use insulating oil as cooling and insulating medium.
The core is made of high quality cold rolled sillcon steel, the oil tank adopts corrugated oil tank without oil conservaor.
S11/S13 series oil immersed distribution transformers use insulating oil as cooling and insulating medium.
The core is made of high quality cold rolled sillcon steel, the oil tank adopts corrugated oil tank without oil conservaor.
Vacuum oil injection process is adopted to effectively prevent oxygen and water from penetrating into transformer oilresulting in the decline of insulating oil performance.
It is a new generation of energy-saving and environmental protection products.
Product features of oil immersed transformers :
1.No load voltage regulating transformer need to adjust the tap of high-voltage side only when the power is cut off,
so as to change the ratio of the transformer to regulate the voltage at the low-voltage side.Its regulation range is small, generally within ± 5%, It can only be adjusted once or twice a year.Most transformers in power system are no-load tap transformers.
3.No excitation voltage regulation refers to no-load voltage regulation,which can be adjusted only when the transformer is off.On load tap chaning transformer can change the voltage by changing the tap position when it is on running.
4.Switch has the advantages of frequent on-off, no spark and long service life.The traditional trigger circuit of power electronic switch has the problem of electrical isolation.The application of optical fiber communication technology to the medium and high voltage trigger control system can effectively solve the problem of high and low voltage electrical isolation.
