CT Power Supply Current Transformer For Power System High Voltage Power

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:

1. Mainly used in high-voltage cable transmission, where low-voltage AC power and DC power cannot be obtained. Work site
2. The high-voltage cable must have an environment that provides CT energy
3. Overhead cables, underground branch cables, branch boxes, etc. are all suitable for CT energy extraction (three-core cables cannot extract energy)
4. The energy extraction of the CT power extraction device depends on the primary current of the high-voltage cable. If the energy extraction device can meet the load equipment, the energy extraction equipment can be customized or multiple CTs can be used in parallel to increase the power extraction capacity.
5. The high-voltage line and the power failure or the serious lack of current make the back-end loaded equipment unable to work normally. The CT power taking device wakes up the super capacitor and switches instantly, and the super capacitor continues to supply energy to the loaded equipment to ensure that the power is cut off and the current is insufficient. Can continue to work under the circumstances.
6. The specific performance parameters of the CT power take-off device need to be customized according to the actual situation of the project.

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;
