Summarization
SG series single - phase and three - phase dry type transformer adopts high quality material and advanced technology , it has advantages of damp - proof and convenient maintenance, it can be applied to such power transmission and distribution places like underground railway , high building, airport, station, wharf, enterprise, tunnel, etc. It is mainly used in power supply occasions of AC 50~60Hz and voltage less than 500V.
Application
1) Electrochemical industry: It's the most industries apply to rectifier transformer, electrolyze non-ferrous metal compounds for aluminum, magnesium, coppr and other metal.
2) Traction with dc power supply: It is used in dc grid of mining or city electric locomotive dc. Due to the valve side joint overhead lines occur the short circuit fault always, dc load amplitude becomes larger and electric locomotive starts frequently, which will cause varying degrees of short time overload. Therefore, temperature rise and current density of rectifier transformer will achieve a lower limit. The impedance is about 30% greater than the corresponding power transformer.
3) Transmission with dc power supply: It is mainly used in dc motor power supply in the electrical drive, such as the armature and excitation of rolling machine.
