Gas-filled voltage transformers

Gas-filled voltage transformers series NOG

Gas-filled voltage transformers series NOG

Designation

Instrument voltage transformers with SF6 insulation NOG are meant for AC circuits with frequency of 50 Hz or 60 Hz in order to transfer measurement information signal to measuring, protection, automation, alarm and control devices.

The transformers are SF6 filled and are equipped with pressure inspection tool and warning instrument. If required by a Customer, the transformers can be equipped with SF6 density transmitter with warning instrument of SF6 upper and bottom pressure level.

Design

Transformers’ design shall make allowance for protecting device (diaphragm) which will prevent from excess voltage increase inside the transformer higher then 7 kgf/cm2 in case of an accident due to the internal insulation breakdown and arcing.

Gas flow through the protecting device shall be upward-directed out of the maintenance staff area.

Transformers are environment mechanical agents’ resistant in accordance with GOST 17516.1 and endure seismic vibrations up to 8 scores inclusively.

Transformers’ design is distinguished by the number of secondary windings and secondary windings’ voltage.

Technical data

If required by a Customer, secondary windings’ nominal rated power can be changed in accordance with DSTU GOST 1983-2003 in case accuracy rating is considered.

Maintenance

The transformers NOG feature insulation stable behavior within the whole lifetime and do not require intermediate and general repair along with drying and insulation replacement. The transformers are explosion- and fireproof. The metal structure does not breakdown. There is no fire in case of short-circuit. SF6 pressure is visually controlled using inspection tools. Also it has control panel with SF6 upper and bottom level alarm.

Documents and warranties

The transformers correspond to the requirements of DSTU GOST 1983-2003, technical specification and production drawings. In case transportation, storage, installation and operational conditions are observed, the plant undertakes to replace or repair free of charge broken down transformer within the warranty period provided all the requirements of operation’s manual are observed by a Customer.

The transformers correspond to the following requirements:

  1. average lifetime is 30 years;
  2. warranty shelf life:
    • from the time of placing in service – 3 years;
    • from the date of dispatch from the manufacture’s site – not more then 3,5 years.

Gas-filled voltage transformers series ZNOG

Gas-filled voltage transformers series ZNOG

Designation

Instrument voltage transformers with SF6 insulation for indoor installation ZNOG are designed for use in packages switchgears with SF6 insulation (KRUE) to supply electrical measuring instruments, protective and warning circuits. They can also be used as test transformers while getting supply from the part of secondary windings. The transformers are meant for indoor operation.

The transformers are SF6 filled. Pressure control is an integrated control over the whole packaged switchgear KRUE.

Design

Transformers’ design provides for protecting device (diaphragm) which prevents from excess voltage increase inside the transformer higher then 7 kgf/cm2 in case of an accident due to the internal insulation breakdown and arcing. Gas flow shall be streamlined along the transformer tank.

Technical data

The transformers series ZNOG feature below mentioned parameters.

Maintenance

The transformers feature insulation stable behavior within the whole lifetime and do not require intermediate and general repair along with drying and insulation replacement. The transformers are explosion- and fireproof. The metal structure does not breakdown. There is no fire in case of short-circuit.

Documents and warranties

The transformers correspond to the requirements of DSTU GOST 1983-2003, technical specification and production drawings. In case transportation, storage, installation and operational conditions are observed, the plant undertakes to replace or repair free of charge broken down transformer within the warranty period provided all the requirements of operation’s manual are observed by a Customer.

The transformers correspond to the following requirements:

  1. average lifetime is 30 years;
  2. warranty shelf life:
    • from the time of placing in service – 3 years;
    • from the date of dispatch from the manufacture’s site – not more then 3,5 years.
