Casing for Overhead Recording-type Remote-transmission Fault Indicator
In a complex power grid environment, stable operation begins with solid protection. The enclosure we specifically designed for overhead line oscillographic fault indicators is not just a protective cover, but also the cornerstone to ensure that the equipment can conduct long - term accurate monitoring, reliable oscillogram recording, and stable communication in harsh outdoor environments.
- Strong power-taking ability：By adopting a unique structural design and iron core processing technology, it is ensured that the upper and lower surfaces of the iron core are in reliable contact. An adjustment spring is designed inside the upper bent beam, which allows a large range of movement of the iron core, thus ensuring a reliable combination of the upper and lower iron cores.
- High protection level design：The lower part of the shell is sealed by means of a buckle and the combination of two O-rings, which effectively prevents water vapor from entering. The bottom cover can be opened, and the protection level is high.
- Impact resistance and corrosion resistance：It has a sturdy structure, can withstand natural impacts such as wind, frost, rain, snow, and hail. After special surface treatment, it has good chemical corrosion resistance and is suitable for changeable environments such as industrial areas and coastal areas.
Power-taking performance
The abscissa in the above figure represents different loads, the main ordinate represents the power output by the power-taking CT (unit: mW), and the secondary ordinate represents the voltage output by the secondary coil of the power-taking CT (unit: mA). Under different primary current conditions, the output power curves of the energy harvesting module. From top to bottom, the secondary-side loads are 100, 200, and 300 ohms respectively.
Sampling performance
Using a Rogowski coil for current sampling can correctly reflect the changes in the primary current, including information such as amplitude and angle.
