Serye TVI SF6 Inductive Voltage Transformer

Overview

Ang TVI (Inductive Voltage Transformer) mao ang resulta sa praktikal nga karanasan sa pag-uswag og SF6 instrument transformers ug inductive voltage transformers alang sa PASS ug GIS. Kini nga SF6 gas insulated inductive type of voltage transformer gigamit para sa revenue metering ug proteksyon sa high voltage networks. Gi-disenyo kini para molihok sa labi nagkalain-laing kondisyon, gikan sa polar hangtud sa desert climates. Ang paggamit sa composite insulator ug pressure relief device sigurado sa mas dako nga seguridad ug mas taas nga performance sa labi mapuslanon nga mga kapaligiran.

Advantages

Ang TVI, tungod sa paggamit sa SF6 gas ug composite insulator, naghatag og daghang abilidad:
● 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.
