Feedthrough current transformer structure without its own primary winding carrier (load current) wire from L1 to L2 through the round (or other shapes) by rolling silicon steel core made from a coil winding effect. The secondary winding is wound directly on the circular uniformly core, and the secondary load meters, relays, transmitters and other current coil in series to form a closed loop, since the feedthrough current transformer does not have a primary winding, which according to a ratio Winding through the transformer iron hearts turns to determine the more high-voltage transformer Foshan mandrel turns, variable ratio is smaller; on the contrary Huizhou high voltage transformers, the less the mandrel turns, variable ratio, the rated current ratio I1 / n: where once the rated current feedthrough I1-- one turn; n-- mandrel turns. The role of transformer are the following: the primary circuit of high voltage and high current into the standard position of the secondary circuit, usually rated secondary voltage of 100V, rated secondary current is 5A, so that the measured site instrumentation and protection equipment standardization and the insulation level of secondary devices can be low-voltage design, compact structure and thus cheaper prices. All secondary equipment available low voltage, low current control cables, wiring within a single screen, a simple, easy to install. At the same time, easy to focus on high-voltage transformer Zhuhai bamboo processing, enabling remote control and measurement. Secondary circuit loop is not a limitation. Can be Y-shaped, △ shaped or V-shaped connection transformer, thus wiring flexibility. Meanwhile, the secondary equipment maintenance, as well as adjusting the exchange test, once the system is running without interruption, only suitably changed secondary wiring can be realized. The secondary equipment and staff with high voltage isolation section and the secondary side of the transformer are grounded, thus ensuring equipment and personal safety.
