CT Series Power Transmission Line Energy Acquisition Devices
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 application range of ct series power transmission line energy
acquisition devices includes: Power equipment installed on the
high-voltage side of high-voltage transmission lines: wire
temperature, breeze vibration, galloping, secondary pitch
oscillation, tension, and ice monitoring devices on high-voltage
overhead transmission lines. Power equipment that is difficult to
obtain power near high-voltage transmission lines: various
monitoring devices on underground power cable lines, monitoring
equipment in ring network cabinets, etc. Performance
characteristics: Inductive energy extraction, high efficiency and
reliability, maintenance-free open-type energy acquisition
transformer, easy to install, simple wiring, the energy acquisition
module adopts metal shielding package, good airtightness, adapt to
harsh environments, stable operation, and can work under the
condition of line current changes The stable output adopts
switch-type regulated voltage standard design, the output voltage
is stable, the ripple is small, the maximum output power can reach
more than 150W, it can work continuously at 3000A current, and it
can be installed on the transmission line of any voltage level from
6kV to 500kV.
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;
