Product Description
1. Product Functions
LB-132W2 type current transformer applies to AC power systems at highest voltage of 132kV and rated frequency of 50Hz/60HZ, The functions are current, electric energy metering and measuring, busbar differential protection, overcurrent protection, and distance protection.
2.Standards
IEC Standard: IEC60044-1 (Current Transformer)
National Standard: GB1208 (Current Transformer}
3.System condition
System Rated Voltage: 123kV,132kV
System Highest Voltage: 123kV,145kV
System Rated frequency: 50Hz or 60Hz
System neutral earthing method: effectively earthed
4.Structure feature
• It is oil/paper insulation system, the primary insulation is wound from high voltage cable paper. and is placed several capacitor screen of voltage division in the primary insulation, which can improve electric field distributing and decrease the consumption of insulation material. It will be immersed with transformer oil after desiccating under vacuum. It has advantages of stable and reliable performance of insulation,rich successful experience, a long life time and convenient maintenance.
• Perfect fluidity perormance of transformer oil is good for heat dissipation, it also has self recover ability for the failure of panial discharge caused by air bubble and dust.
• The current ratio can be changed easily by change the connection method of connecting plate on oil conservator to series or parallel connection.
• Hermetically sealed stainless steel metallic bellows is installed on the top, which protect the transformer oil form moisture and extend the life time, also there is a oil level gauge on the bellows for observing the changing of oil volume.
• There is a multi function oil drain valve on the base, which make it more convenient for sampling, draining and refillirlg.
• The primary terminal and secondary terminal board are made of epoxy casting, the seal performance is more reliable.
• There is a individual terminal of earth screen in the terminal box.
• The oil conservator and base etc use DACRAL (Zinc/Chromate coatings) for resistance to corrosion, which gives a high degree of corrosion resistance.
The primary over -voltage protection device and secondary open circuit over voltage protection device can be provided according to -
the requirements of use
