LZZBJ9-35D, 40.5D multi-winding large capacity current transformer
This type of current transformer is an epoxy resin cast pillar-type fully enclosed product, suitable for power systems in indoor installations with a rated frequency of 50Hz-60Hz and a rated voltage of 40.5kV and below, used for electric energy measurement, current measurement, and relay protection. This product complies with the standards IEC 60044-1-2016 and GB/T 20840.2-2014 'Current Transformers'. With the transition to electrical intelligence and networking, especially in substations where current transformers have multiple secondary circuits and protections, it not only requires self-differential protection but also needs to cooperate with upper and lower level differential protection to form multiple interlocking protections, as well as meet the demand for large capacity of secondary equipment. This product can combine 4-6 secondary windings, achieving a conventional capacity of 2-3 times when using 4 secondary windings. It features a small size, lightweight, suitable for arrangement in any position and direction, and requires no special maintenance, only regular cleaning of surface dirt.
