overview
yihe is a major supplier of complete electrical equipment for the power grid and power generation system. as the leader of the component group, yihe actively responds to the standardization and customization requirements of the low-voltage cabinet of the state grid. it participated in the first batch of joint design, completed the first batch of prototype trial production, passed the acceptance of experts from the state grid, passed the full type test, and passed the testing and detection with high standards. based on the standardization requirements of the state grid for distribution network products, a total of 4 categories and 8 subcategories have been designed for low-voltage switchgear schemes. this design follows the principles of "safety, reliability, durability, unified standards, universal interchangeability, reasonable grading, and wide applicability", achieving the goal of simplifying operation and improving efficiency. compared with similar products, it has obvious advantages.
performance characteristics
unified design of standardized product solutions.
the electrical parameters are simplified into three levels and four categories
which not only meet the requirements of use but also have unified standards.
standardizing secondary principles
interfaces
and labeling for safer installation
operation
and maintenance.
the short-term withstand current of the 2500a circuit breaker combination cabinet has increased to 65ka.
unified civil engineering interface
standardized products can seamlessly connect with the foundation.
operate at full load according to the decentralized system 1.0
and pass the temperature rise test without reducing the capacity.
realize functional configuration and unified cabinet integration to meet interchangeability requirements.
add emc testing to improve product anti-interference performance.
