Split Core Current Transformer CT Power Supply Energy Transformer
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
CT power taking device is a new type of induction power taking
device that uses electromagnetic energy induced around high-voltage
transmission lines to obtain electrical energy. This device uses
the principle of electromagnetic induction, uses a current
transformer to directly induce AC voltage from the high-voltage
bus, and then undergoes rectification, filtering, and voltage
stabilization to obtain a stable and reliable DC voltage to provide
a stable power supply for electrical equipment installed nearby. It
can ensure the long-term stable power supply of the load equipment.
Suitable as a power supply device for online detection, monitoring,
inspection, anti-theft and other electrical equipment on
high-voltage transmission lines.
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;
