摘要
本文设计了一套可以满足6300A断路器脱扣试验的大电流电流源系统,试验能力达到三相长期工作电流10kA和短时80kA、5s。在电路计算分析的基础上,介绍了不建专用变电站解决大容量远距离供电的配置和布局方案,该方案节能、节材、节省资金,并且效果良好。
This paper discusses the design of current source system for Strong-current which can comply with the requirements of tripping test for 6300A circuit breaker,the testing ability of which may reach 10kA for three-phase long-term current and 80kA,5s for three-phase short-term current.The paper describes the scheme for configuring and arranging the long-range high-capacity power supply which is supplied without building a special transformer substation on the basis of calculation and analysis of the circuit.The scheme can save energy,materials and funds with a good effect.
