一、Description
    The current transformers of the types LQZJ(2.3)- 10 are casting resin and full - enclosed products.
They are used for metering electric energy and current, relay protection in the electric system up to rated frequency 50Hz or 60Hz and rated voltage lOkV. The transformers can be executed accordinS to the standards IEC60044 -1 and GB1208.

三、 Construction
      This current transformer is fullv enclosed and post type. It has 8 good ability of antipollution
and moisture - proof. If being installed, the terminal screwmust be fixed tightly.  The primary winding of the LQZJ2 - 10 is subsection type. It can he two current ratios throuS;h in series or parallel connection ( see fig l ).  When the primary current is bigger than 400A of parallel connection, it must be connected with Pl and Cl, P2 and C2 by assistant wiring copper raft, before the busbar of the switch cabinet connectinS; the copper raft (The cross section of the assistant wiring copper raft must be bigger than 500 mm2. )
