Current Transformer Used in High-Voltage Cable Transmission Where
Low-Voltage AC Power and DC Power Cannot Be Obtained
1. The principle of CT power supply
CT power supply, that is, use the CT installed on the power line as
a device to obtain power. The power supply is divided into two
parts, one is the CT used to obtain electricity, and the other is
to convert the electrical energy obtained by the CT into the
required DC voltage and current power supply module.
Application range:
The CT power supply is mainly used on power lines, which can solve
the problem that the equipment cannot get other power supply.
3. Technical Features
1) Since the CT is installed on the power line cable, its
insulation is relatively high
2) CT power installation is more convenient, and the price is low.
3) It is more suitable for the power supply of low-power equipment
The power-taking device is a kind of power source that obtains
electric energy through the principle of CT electromagnetic
induction
The device consists of two parts: current transformer (CT) and
power conversion module.
A high-stability current induction power supply with battery
charging and discharging management. This series of current
induction power supplies use potential lake technology and
high-frequency isolation DC/DC conversion technology, supplemented
by power supply status monitoring and battery charging and
discharging management, and supporting special energy mutual
inductance With small size and high power conversion efficiency, it
meets the requirements of safe power supply in a variety of harsh
conditions such as large current impacts and load jumps in the
power grid.
Feature:
1. Reasonably select the induction power supply and its energy
storage components according to the conventional operating value of
the wire current, power curve and electric power;
2. Due to the magnetic circuit, there will be a slight ticking
sound when the energy transformer is working, which is a normal
phenomenon;
3. The principle of the induction power supply module is completely
different from that of the conventional power supply, and it must
not be connected to other power interfaces;
