Split Core Current Transformer For Cable Status Monitoring,
High-Voltage Power Transmission Monitoring
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 ct power acquisition device is a new type of power supply
device that uses the principle of electromagnetic induction to
acquire electric energy and realizes a stable voltage output. The
device has long-term stable and reliable operation, mature
technology, strong adaptability to changes in the current of the
transmission line, self-protection of short-circuit and inrush
current, and can provide reliable power for various transmission
line online monitoring and monitoring equipment.
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;
Parameter:
