NICORE -Characteristics and Application of R core

2019-07-30

A voltage transformer is similar to a transformer and is an instrument used to change the line voltage. However, the purpose of the voltage transformer to change the voltage is to supply the measuring instrument and the relay protection device to measure the voltage, power and energy of the line; or to protect the valuable equipment, motor and transformer in the line when the line fails, so The capacity is generally designed to be relatively small.

The core of the voltage transformer is mainly composed of stepped R, toroidal and laminated cores. The R core independently developed by Nicore is one of the star products.

In terms of raw materials, the R core of Nicore is based on high-quality oriented silicon steel sheets (Nippon Steel NSC, Kawasaki JFE and POSCO, etc.); in production and processing, Nicore uses a skeleton and R winding machine to take silicon steel sheets. Winding into an R core, the winding is quick and convenient and the production efficiency is high; structurally, the R core is wound from a continuous curved strip of material from small to large to small, in the direction of the magnetic path. The cross section is circular, the window is rectangular, the magnetic circuit is completely closed, no magnetic leakage, accurate size and excellent magnetic properties.

Because of its small size, high efficiency, low magnetic flux leakage, safety and reliability, and low noise, in addition to voltage transformers, R cores of Nicore can also be widely used in 50Hz transformers, reactors and inductive choke in electronic equipment. Electromagnetic elements such as flow coils.
