Ankerui open type current transformer for non dismantling installation and modification

Description :

　　Preface

　　The current in power generation, transformation, transmission, distribution, and consumption lines varies greatly, ranging from a few amperes to tens of thousands of amperes. For the convenience of measurement, protection, and control, it is necessary to convert to a relatively uniform current. In addition, the voltage on the line is generally high, and direct measurement is very dangerous. The current transformer plays a role in current conversion and electrical isolation.

　　A current transformer is an instrument that converts high primary current into low secondary current based on the principle of electromagnetic induction for measurement. A current transformer is composed of a closed iron core and winding. Its primary winding has very few turns and is connected in series in the circuit where the current needs to be measured. The principle of current transformer is based on the principle of electromagnetic induction. A current transformer is composed of a closed iron core and winding. Its primary winding has very few turns and is connected in series with the line that needs to measure the current, so it often has all the current flowing through the line. The secondary winding has a relatively large number of turns and is connected in series with the measuring instrument and protection circuit. When the current transformer is working, its secondary circuit is always closed, so the impedance of the measuring instrument and protection circuit series coil is very small, and the working state of the current transformer is close to a short circuit.

　　Overview:

　　AKH-0.66K seriesLow voltage switchable current transformerEasy to install, no need to dismantle the busbar once, can also be operated with electricity, does not affect the normal use of electricity by customers, and can be used in conjunction with relay protection, measurement, and metering devices. Mainly used in power distribution system renovation projects, it is easy to install, does not require dismantling the busbar once, and can also be operated with electricity, without affecting the normal use of electricity by customers.
