Palawan ng Produkto
Ang 35kV oil-immersed earthing transformer ng Rockwill ay espesyal na in disenyo upang magbigay ng isang maasahang neutral grounding point sa mga medium-voltage networks kung saan hindi available ang direct grounding. In disenyo ito na may zig-zag winding configuration, tiyak na nagbibigay ng optimal na zero-sequence impedance, na mabisa sa pag-limit ng ground fault currents at pagsustina ng transient overvoltages.
Ang matibay nitong oil-immersed construction ay nagtagal na insulasyon reliability at thermal performance sa outdoor environments.
Pangunahing Katangian
Zig-Zag Winding: Nagbibigay-daan sa controlled neutral grounding at mabisang zero-sequence current flow para sa protective device coordination.
High Insulation Performance: Sumasang-ayon sa 35kV-class insulation levels at withstand voltage standards.
Efficient Core Design: Gawa sa cold-rolled grain-oriented silicon steel upang bawasan ang core losses at no-load current.
Copper Windings: Ang oxygen-free copper ay nag-aangkop sa reduced winding losses at superior short-circuit resistance.
Fully Sealed Tank: Maintenance-free na may anti-corrosion surface at integrated oil conservator (kung kinakailangan).
Standardized Manufacturing: Itinayo ayon sa IEC 60076, IEEE, at customer-specific utility codes.
Karaniwang Application
Medium-voltage distribution systems (33/35kV class)
Renewable energy substations (solar, wind)
Isolated generator grounding systems
Utility and industrial MV feeders requiring neutral grounding
Protection system grounding via NGR (Neutral Grounding Resistor)
