Description
Product Information
The IXR 24kV 630A 20kA eco-friendly gas-insulated ring cabinet circuit breaker mainly complies with the following standards:
- GB 1984 – 2014 “High-voltage AC circuit breakers” (equivalent to IEC 62271 – 100:2008). This standard comprehensively regulates various technical indicators, performance requirements, and test methods of high-voltage AC circuit breakers, ensuring the reliability and safety of the product during the opening and closing operations of high-voltage circuits, enabling it to accurately and stably cut off fault currents and safeguard the stable operation of the power system.
- GB 1985 – 2014 “High voltage a.c. disconnecting and earthing switches” (equivalent to IEC 62271 – 102:2001 + A1:2011). This standard focuses on clarifying the insulation performance, mechanical characteristics, and switching operation specifications of disconnecting switches and earthing switches, helping the product to achieve key functions such as electrical isolation and earthing protection, meeting the power distribution and safety protection requirements under different working conditions.
- GB 3906 – 2020 “3.6kV~40.5kV AC metal-enclosed switchgear and controlgear” (equivalent to IEC 62271 – 00:2021). It provides guidelines for the structural design, protection level, and internal electrical layout of metal-enclosed switchgear and controlgear, facilitating the efficient and safe control of power transmission in a closed environment and protecting the equipment from external interference.
- DL/T 404 – 2023 “3.6kV~40.5kV AC metal-enclosed switchgear and controlgear” (equivalent to IEC 62271 – 200:2021). Combining the actual application scenarios and operation and maintenance requirements of the power industry, this standard details the operation guidelines for equipment selection, installation and commissioning, daily inspection, and fault handling, ensuring the stable operation of the product throughout its entire life cycle.
