核电汽轮机仪控机柜升级的方案研究

Upgrade Solution of Nuclear Power Steam Turbine Control Cabinets

国内某在建核电站从国外引进的汽轮机仪控机柜,防护等级须从IP20升级为IP31。根据需求,提供一套机柜降温的升级方案,现场实施后效果明显,柜内温度回落到允许范围内。此方案适用于同类型的各种机柜,并且实施过程不影响机柜的正常运作。

A domestic nuclear power plant imported from abroad turbine instrumentation and control cabinets, protection class of the cabinet has been requested upgrading from IP20 to IP31. The author based on actual demand, has provided a upgrade program of reducing the temperature of the cabinet, after the implementation of the program in the field, the effect is obvious, inside temperature of the cabinet has dropped to within the allowable range. This program applies to all cabinets of same types, and the implementation process does not affect the normal operation of the cabinet.
