摘要
在 6～ 1 0kV成套配电装置中 ,由于电弧短路引起开关柜的故障率目前很高。不少电弧短路使整段配电装置着火 (有时伴随爆炸 ) ,设备损坏 ,造成用户长期停电 ,损失非常大。本文简要介绍国外 (前苏联 )成套开关柜电弧短路保护装置的研制和运行情况 。
For 6～10kV complete set of power distribution equipment, many faults of switchgear cabinet are mainly caused by arc short circuit. Many arc short circuited faults result the whole section of power distribution equipment on fire (sometimes explosion). The equipment is damaged which brings a long term outage to customers. Therefore, the development and operation performances of the protection against arc short circuited fault for switchgear cabinet abroad (Russia) are presented in this paper.
