Serye ng TVI SF6 Inductive Voltage Transformer

Overview

Ang TVI (Inductive Voltage Transformer) ay ang resulta ng praktikal na karanasan sa SF6 instrument transformers at inductive voltage transformers para sa PASS at GIS. Ang SF6 gas insulated na uri ng inductive voltage transformer na ito ay ginawa para sa revenue metering at proteksyon sa mataas na voltageng mga network. Ito ay disenyo para sa pinakamagkakaibang kondisyon, mula polar hanggang sa desert climates. Ang paggamit ng composite insulator at pressure relief device ay nag-uugnay sa mas mataas na seguridad at mas mataas na performance sa mga napakapulot na kapaligiran.

Advantages

Ang TVI, dahil sa paggamit ng SF6 gas at composite insulator, ay nagbibigay ng maraming mga benepisyo:
● highly reliable equipment
● explosion proof design
● maintenance free
● dielectric quality not depending on long treatments
● negligible level of partial discharge
● dielectric mean not subjected to ageing
● wide safety margin against saturation and ferro-resonance
● high seismic withstand capability
● suitable for applications in mobile substations
● higher performance in very heavy polluted environments
● available with a gas insulated disconnector for increased

Flexibility during operation

● Suitable for both metering and protection
● Magnetic cores made of laminated steel with oriented grain and a high level of permeability
● Windings made of electrolytic copper
● Primary winding connected directly to the high voltage side while the secondary winding supplies the low voltage panels
● Insulation system designed to guarantee a life cycle of 30 years. Declared maximum gas leakage: less than 0.1 % per year
● Safety margin for normal wind loads, stress from conductors and seismic forces
● Construction in conformity with national pressure standards
● Installed on a metal support with four eyebolts for lifting.
