Abstract

Low-voltage electrical apparatus serves as a crucial component in the construction of new power systems.With the rapid development of fields such as renewable energy generation，DC factories，and data centers，higher performance requirements are being imposed on these apparatuses.This paper reviews the collaborative research and application progress in the digital and intelligent design of low-voltage electrical apparatus conducted by the Chint group-Xi'an Jiaotong University joint innovation center，with a focus on four aspects：digital design，advanced testing technologies，intelligent fault perception，and the development of new DC circuit breaker products.In terms of digital design，emphasis is placed on the magnetohydrodynamic modeling method for arc behavior in air circuit breakers and its application in the optimized design of arc-extinguishing systems.Regarding advanced testing technologies，techniques including grid voltage measurement，X-ray imaging diagnostics，and arc temperature spectroscopy are summarized and analyzed.In the area of intelligent fault perception，high-precision intelligent detection methods for AC/DC arc faults and leakage currents are outlined，and research progress on AC arc fault line selection methods as well as the integration technology of electrical safety fault detection into circuit breakers is introduced.Finally，the progress in the development of new lowvoltage DC circuit breaker products is described，and the development trends of low-voltage DC interruption technology are discussed. Results from engineering demonstration applications indicate that the digital and intelligent design of low-voltage electrical apparatus has explored and established an efficient research and development model for new high-performance products.
