Product Description

Oil-Immersed Combination Transformer Substation

Model and explanation:
  ZGS9(11)-[Z/H]-[ ] /( )
  Z:combination-type substation
  G:integrating box-type
  S:three phases
  9(11):serial number
  -[Z/H]-:high voltage connection method(Z for terminal and H for ring net)
  [ ] /:a number in [ ] indicates the rated capacity of the transformer(kVA)
  /( ):a number in ( ) indicates high voltage class(kV)

Introduction:
  It's applied indoors or outdoors and provides eletricity reliably.It is convenient to be installed and operated due to a small size and a reasonable structure.Besides,its cost is low.It's applied for industrial parks,residental areas,business centers,road lamps and tall buildings.
  An oil case contains the main body of the transformer,a high voltage load switch,fuses,etc.A smaller size is the difference between the combination-type substation and a normal national substation.

Reference standards about specification and technical requierments:
China national standard:GB 1094.11-2007

Structure:
  It's made up of two parts.The front part is a high&low voltage room containing high&low terminals,load switches,a operation handle of an off-circuit tap-changer,insertion-type fuses,a pressure relief valve,a thermometer of measuring the temperature of oil,an oil level indicator,a hole for immitting oil,an oil drain valve,etc.The rear part is an oil case and some cooling fins.The main body of the transformer,high voltage load switches,the off-circuit tap-changer and fuses are in the oil case whose structure provides it with an entire seal.The application of consealed and stainless steel bolts of high strength and an oil-resistant rubber washer provides the cap of the oil case with an seal.
