imported resin, long-life
outdoor and high-accuracy
stainless steel or electrostatic spray steel box
Description
This model combined transformer (another name is metering tank) is composed of voltage and current transformer, it is applied to three-phase circuit of AC50Hz and rated volt being 10kV or lower, to be used for volt, current and energy measuring as well as relay protection, it is suitable for urban and rural power network outdoor transformer substation in addition to kinds of volt transformer substations in industrial enterprise. Adding active and reactive energy meter onto combined transformer is named as high volt power metering tank. This product could replace oil immersed type combined transformer (metering tank).
Construction
Voltage transformer possesses indoor epoxy resin casting mechanism, its iron core is exposed, with lapping mechanism of super-quality grain-oriented cold-rolled silicon steel sheet, the primary and secondary coil are installed onto center post.
Current transformer possesses epoxy resin casting mechanism; its iron core is closed, with rolling mechanism of super-quality grain-oriented cold-rolled silicon steel sheet.
Two volt transformers (PT) and two current transformers (CT) are installed into one sealed iron box, forming one body.
