Working Principle
The circuit block diagram is shown in the figure below. In the figure, the capacitor C is the high-voltage power-taking capacitor, and T is the power-taking transformer. These two components constitute the C-L power-taking mode. The advantage of this method is that the power is large and the overall volume is small.
Block Diagram and Terminal Description
The high-voltage powering device produced by our company has the merits of large power taking, flexible combination and wide power and voltage coverage. It can satisfied with working power supply of all models of primary and secondary fusion intelligent switch and controller, and can solve the fatal damage caused by ferromagnetic resonance of traditional PT. It is an ideal replacement product to replace traditional PT.
Application Benefit Evaluation
Actual Application Scenarios and Promotion
· Core Application in Power System:Has been applied in more than 20 units including XJ Group and Pinggao Group, providing power for online monitoring devices (such as conductor temperature sensors and insulator leakage current monitoring devices) of 110kV and above transmission lines. The failure rate of equipment in operation is <0.3%, which is significantly lower than the traditional CT energy-harvesting scheme (failure rate 5-8%).
· Cross-Field Expansion Effect:Applied in scenarios such as railways and oil field pipeline cathodic protection power supplies, ensuring that the device's anti-electromagnetic interference performance in railway scenarios passes the "GB/T 17626.5-2019" Level 4 certification, ensuring that the train control system is not interfered.
Attention
- When using, after connecting the wires, check that the grounding wire is well grounded.
- Noted that the connection must be correct. After turning on the power supply, turn on the load after the output voltage is normal.
- Please do not arbitrarily remake or decompose the power supply, our company is not responsible for all the consequences involved.
