| 一是控流阀（断流阀）：安装在本体气体继电器与油枕之间的水平管道上，可在变压器油箱破裂、溢油或发生火灾排油时自动切断补油管路。 First, flow control valve (cut-off valve): installed on the horizontal pipeline between the gas relay and the conservator of the main body, it can automatically cut off the oil replenishing pipeline when the oil tank of the transformer breaks, overflows or discharges oil in case of fire. 二是火灾探测器：安装在变压器油箱顶部易着火部位，着火时触点动作接通。 The second is fire detector: it is installed on the top of the transformer oil tank where it is easy to catch fire, and the contact acts to connect when it catches fire. 三是消防柜（灭火柜）：安装在主变附近，是排油充氮的执行部件。 Third, fire cabinet (fire cabinet): installed near the main transformer, it is the executive part of oil discharge and nitrogen filling. 四是电气控制柜（箱）：安装在控制室（或保护小室）内，提供工作状态、信号指示、报警信号输出及启动控制。设有转换开关、控制电源开关和手动启动按钮（或消防启动开关）。 Fourth, electrical control cabinet (box): installed in the control room (or protection room), providing working status, signal indication, alarm signal output and start-up control. There are transfer switch, control power switch and manual start button (or fire start switch). 五是交流空气开关：为消防柜内的加热器、照明提供交流电源。 Fifth, AC air switch: provide AC power for heater and lighting in fire cabinet. |
