Characteristic of structure
The product has advantages of reasonable design and explosion-prooffunction
Good sealing performance.
Low partial discharge level.
The product shows capacitance, low magnetic flux density and antiresonance.
Low dielectric dissipation factor, strong weatherproof capability.
Strong seismic intensity.
Characteristic
The product adopts box type structure, is composed of primary terminal board, wire leading pipe, high-voltage insulated bushing, shell, machine body, junction box and density relay and so on (see table 2for outline installation dimension).
Transformer winding adopts single stage structure, the composite insulation layer combined with SF6 gas and diamond doted glue polyester film enables the product to withstand high voltage. Machine body is fixed in the shell, lead-out wire of secondary winding is led in the junction box through
Secondary terminal board, there are terminals in the junction box for user connection. The shell not only can be used for placing machine body, has functions of installation and fixing, but also can be used for setting theSF6density relay andSF6gas charge valve. The high-voltage insulated bushing
adopts high-strngth porcelain bushing or silicon rubber composite bushing, it is able to withstand large pressure without be damaged, it connects the shell with primary terminal board firmly through the upper and lower flanges of bushing. The shell also is equipped with earth plate.
