Low voltage anti-electricity stealing metering box used for L(J)MZD-0.5SYD type metering
Type meaning Patent Number: ZL2012 1 0005739.2
Summary
In order toimprove smart level of electric power metering management,we have developedanti-electricity stealing low-voltage combined transformer used for metering. The transformer is installed on transformersecondaryoutgoingcolumnand is used for low voltage currentandelectric energy measurement andprotection. The instrument transformer has unique anti-electricity stealing design structure, to preventproblem of voltage signal failing to be taken out caused by man-made and natural loosenessof transformer from affecting power meter I. It eliminates occurrence of stealing electricity from secondary column from headstreamand effectively improves smart level of meter A management.
