| 当变压器发生火灾时, 装置如处于自动运行状态，则在接收到重瓦斯动作信号、温感火灾探测器动作信号、断路器跳闸信号、油箱超压信号后装置立即启动； In case of transformer fire, if the device is in automatic operation state, the device will start immediately after receiving the action signal of heavy gas, action signal of temperature sensitive fire detector, trip signal of circuit breaker and over pressure signal of oil tank; 装置如处于手动运行状态，则在观察到火灾时，按控制单元触摸屏面板上的手动启动按钮后装置立即启动； If the device is in the manual operation state, when the fire is observed, press the manual start button on the touch screen panel of the control unit to start the device immediately; 装置启动后，首先快速排油阀打开使变压器油箱顶部部分热油通过排油管排出，释放压力，防止二次燃爆；同时断流阀关闭切断油枕至油箱的补油回路，防止火上浇油； After the device is started, firstly, open the quick oil drain valve to discharge the hot oil at the top of the transformer oil tank through the oil drain pipe to release the pressure and prevent the secondary combustion explosion; at the same time, close the block valve to cut off the oil filling circuit from the conservator to the oil tank to prevent the oil from being poured on the fire; 排油15秒后，充氮阀打开使氮气从油箱底部注入搅拌，强制热冷油的混合，进行热交换，使油温降至闪点以下，同时充分稀释空气中的含氧量，达到迅速灭火的目的。 After 15 seconds of oil discharge, the nitrogen filling valve is opened to inject nitrogen from the bottom of the oil tank for mixing, force the mixing of hot and cold oil, conduct heat exchange, reduce the oil temperature below the flash point, and fully dilute the oxygen content in the air to achieve the purpose of rapid fire extinguishing. |
