LZZBJ9-20 Current Transformer


SummaryThe current transformer is casting resin and fully enclosed product. It is used formetering electric energy and current, relay protection in therelay protection in the electrical system of rated frequtncy 50Hz or 60Hz and rated voltage 20KV. The transformers be executed according to the standards IEC44-1 and GB20840.1-2010, GB20840.2-2014 Current Transformer.

Type designation


Structural introduction

This type of current transformer is fully enclosed and post type. It is small and light. There are four fixing hole of 4-M10 on the bottom.

Technical parameter

1, Rated insulated level: 24/65/125KV

2, Rated secondary current: 5A, 1A3, Rated primary current, accuracy combination, rated output, dynamic and thermal stability current.4, The conditions of the partial discharge test according to GB20840.1-2010&GB20840.2-2014 Current transformer will be fulfilled without exception.Dynamic thermal stability technical parameters

Note:1, If being request, the measuring class can reach to 0.2S or 0.5S class.2, We can make multi-trans formation-ratio current transformer of single measuring winding or single protivc winding, such as single measuring winding: 100-150-200/5A 0.2 class 10VA, Ith=31.5ASingle protective class: 100-150-200/5A, 5P15 class, 10VA, Ith=31.5A.
