2025-08-04 14:04:52

In the power system, LZZBJ Current Transformer is an important equipment widely used for current measurement and protection. It can proportionally convert high current into low current, facilitating the safe use of measuring instruments and relay protection devices. The LZZBJ series current transformers are highly favored in substations, distribution systems, and industrial power monitoring due to their high precision, stability, and reliability.   

Characteristics of LZZBJ current transformer

1. High precision measurement: LZZBJ current transformers use high-quality silicon steel sheets or nanocrystalline alloy materials to ensure high precision over a wide current range, with small errors, and are suitable for energy metering and relay protection.   

2. Multiple ratio options: Supports multiple ratio configurations, such as 100/5A, 200/5A, etc., to meet the measurement needs of different current levels.   

3. Good insulation performance: epoxy resin casting or SMC insulation materials are used, which are resistant to high temperature, moisture and aging, and suitable for harsh environments.   

4. Compact structure design: small in size, light in weight, easy to install and maintain, especially suitable for distribution cabinets and switchgear with limited space.   

Application scenarios of LZZBJ current transformer

-Substation: used for current monitoring, energy metering, and relay protection.   

-Industrial power distribution system: ensuring current measurement and safe operation of equipment such as motors and transformers.   

-In the field of new energy, precise current detection is achieved in photovoltaic and wind power systems.   

How to choose the appropriate LZZBJ current transformer?   

When making a purchase, it is necessary to consider the rated current, accuracy level, installation method (through type or busbar type), and environmental adaptability. In addition, products that comply with standards such as IEC and GB should be selected to ensure safety and compatibility.   

conclusion

LZZBJ current transformer has become an indispensable component in power systems due to its stable performance and wide applicability. Whether it is a power company, industrial enterprise, or new energy project, the correct selection of LZZBJ current transformers can improve the safety and measurement accuracy of the system.
