The Measuring Handcart is a high-voltage switchgear that integrates real-time monitoring functions. It is designed for 40.5kV indoor power distribution systems. It adopts modular hand-car structure and built-in high-precision current/voltage sensor (CT/PT), which can collect line data in real time and upload it to the monitoring system through RS485 communication, realizing the integration of "switch + measurement". In line with GB/T 1984 and IEC 62271-100 standards, short circuit current breaking capacity of 40kA, mechanical life of more than 10,000 times, suitable for KYN series switchgear, suitable for smart grid, data center and industrial automation scenarios, help operation and maintenance efficiency increased by 40%+.
