摘要
惠阳水厂装有3台1600kVA调速泵变频器专用变压器和2台630kVA厂用变压器,在每台变压器的高压侧采用进口手车式开关柜实施分、合闸操作,每台开关柜装备1只SPAJ141C型继电器实施变压器的过电流和接地故障保护。介绍了该继电器的结构、功能、工作说明和实用效果。
There are three transformers of 1 600kVA for frequency speed control of pumping assemblies and two transformers of 630kVA for industrial power supply in the Huiyang Waterworks. A lorry switch cabin was installed at the high voltage side of each transformer for on off operation and a relay of type SPAJ141C was installed to each switchboard for over current and earth fault protections. The structure, function and operating mechanism of the relay are described.
