Switch mode power supply ct

The power supply current transformer(CT) is mainly used in the power line, can solve the equipment can not get other ways to power supply problems. 1) high-voltage transmission and distribution field: current induction power supply is mainly used for the lack of conventional power supply measures in the field of high-voltage transmission and distribution, in the transmission and distribution network, the voltage is as high as 10KV-1150KV, the working current of tens of amps to thousands of amps, although there is a huge transmission of electricity, many intelligent electronic equipment is lacking due to Although there is huge power transmission, many intelligent electronic equipments cannot be installed due to lack of electricity, or they have to be equipped with expensive and bulky solar or wind power generating equipments, which is like having no water to drink by the Yangtze River. 2) Smart Grid: With the development of the Smart Grid, the demand for intelligent electronic equipments on primary high-voltage equipments (e.g., overhead transmission lines, cables, ring cabinets, etc.) is enhanced, and the applications of the current sensing power supply are becoming more and more widely used, including, but not limited to, power distribution automation, intelligent ring cabinets, overhead transmission lines and cables, and intelligent ring cabinets. The applications of current-sensing power supply are getting wider and wider, including but not limited to: power distribution automation, intelligent ring main unit, overhead transmission line and cable monitoring, high-voltage power-carrying maintenance tools, and other extended applications (such as field communication base station, high-voltage transmission line indicator, etc.), such as: power supply for intelligent switchgear cabinet, power supply for ring main unit, power supply for transmission and distribution detection, and special power supply for fault indicator, and so on.   Specific applications: power distribution automation (distribution line fault indicator), outdoor intelligent switchgear, power on-line detection system (high-voltage transmission monitoring, cable status monitoring), electric power wireless temperature measurement system, active electronic transformer, high-voltage power line operation tools, other high-voltage power line electronic equipment (such as high-voltage power line indicator, etc.).   Read more:  https://www.hemeielectricpower.com/

Current induction power supply, also known as CT power supply or current transformer power supply, draws power from the magnetic field induced by wires. The isolation transformation of the power supply mainly relies on the principle of electromagnetic induction, and can perform both voltage conversion and current conversion; At present, various types of power conversion are mainly based on voltage conversion, from high-voltage power generation and transmission to low-voltage conversion inside electrical appliances. Their basic structures are derived from the voltage conversion mode (such as PT voltage transformer, etc.). energy harvesting current transformer split core power supply CT power supply CT permalloy core   The current induction power supply is different from common power supplies. Its theoretical basis is based on the current transformation of the electromagnetic induction principle. The premise of its energy transformation is that the primary side (often the transmission wire) has sufficient AC current transmission, and no matter how the wire current fluctuates , the power output must remain stable. The current transformer commonly used in the power industry can be regarded as a typical application for drawing power from the power supply.   Read more:  https://www.hemeielectricpower.com/
