The LSY Inflatable Cabinet Current Transformer is a modern solution designed for medium-voltage switchgear systems, offering enhanced safety, compact structure, and high measurement accuracy. This article explores its working principle, key advantages, technical specifications, application scenarios, and how it compares to traditional current transformers. We also provide expert insights, tables, and FAQs to help engineers, procurement specialists, and industry professionals make informed decisions.
The LSY Inflatable Cabinet Current Transformer is a specialized electrical device used in gas-insulated switchgear (GIS) or inflatable cabinet systems to measure and monitor current in medium-voltage networks. It is designed to operate within sealed, gas-filled environments, typically using SF6 or eco-friendly insulating gases.
Unlike conventional open-air transformers, this type is fully enclosed, ensuring:
The working principle of an inflatable cabinet current transformer is based on electromagnetic induction. When current flows through the primary conductor, it generates a magnetic field. This field induces a proportional current in the secondary winding, which is then used for measurement and protection purposes.
Key Working Steps:
In inflatable cabinets, the transformer is embedded in a gas-insulated environment, which enhances dielectric strength and minimizes electrical losses.
