变压器与消防柜之间的排油和充氮管道及线缆。
Oil discharge and nitrogen filling pipes and cables between transformer and fire cabinet.
高温探测器（动作温度：93℃/135℃），主要安装在变压器油箱顶部最易发生火灾处。当油箱超压和油箱顶部区域超温时，发出接点信号作为报警输出传送到消防控制柜。
High temperature detector (operating temperature: 93 ℃ / 135 ℃) is mainly installed at the top of transformer oil tank where fire is most likely to occur. When the oil tank is overpressured and the oil tank top area is overtemperature, the contact signal will be sent to the fire control cabinet as the alarm output.
截流阀安装在气体继电器和油枕之间的水平管道上。当变压器出现非正常溢油或发生火灾排油时，自动切断补油通道。
The shut-off valve is installed on the horizontal pipeline between the gas relay and the conservator. In case of abnormal oil spillage or fire discharge of the transformer, the oil replenishing channel will be cut off automatically.
