电站建设

一、电站建设注意事项 Notice about Power plant construction

◎ 机房一般采用敞开式或是半开式，采用不发生火花的地面，地面平整易于清理。

◎ 如果采用闭式机房，应按《建筑设计防火规范》（TJ16-74）中防爆设计要求设计，必须是单层建筑，门窗一律外开，设置大流量排放装置，防止燃气体积聚集。

◎ 机房与操作间应隔开，不得直接连通，观察窗应双层玻璃，且有钢丝网防护。

◎ 必须有避雷装置。

◎ 配备充足的灭火设备。

◎ 机房现场不能有明火，必须有明显的“严禁烟火”等警示标志。

◎ 发电机组排出的废气中，可能混有少量可燃气体，要设计安装由发动机引向室外的排气管，排气管系统应连接可靠。

◎ Generator Room is usually constructed in open or semi-open type. The floor of generator room should be easily to clean and not easily to spark.
◎ If you want to construct closed generator room. You must construct a single-storey building. The open direction of all the doors and windows must turn outside. Please install some big capacity displacement device to avoid gas gathering.
◎ Generator room and the operation room must be separated, can not be directly connected. The observation window should be with double- deck glass protected by steel wire mesh.
◎ Lightning arrester is necessary.
◎ Prepare enough fire extinguishing appliances.
◎ "No Fire" mark should be obvious, open flame in the generator room is not allowed.
◎ In the exhaust gas, there might be a small amount of combustible gas. So the exhaust pipe of the generator must be leaded to outside of room. The exhaust pipe must be connected tightly.

二、机房设备要求 Requirements for the Equipments in Generator Room

◎机房内的电气设备必须防爆，进行维修时，必须切断电源。

◎在燃气管道进房处，设置紧急阀门，以备厂房发生紧急情况时，可迅速切断气源，此阀门应离操作间很近。

◎要有气体检测报警系统，以检测漏气问题。

◎ Electric equipments in the generator room must be explosion proof. When you repair the equipments, must turn off the power.
◎ Fix an urgent valve at the intake where gas pipe is leaded into room. You can cut off the gas in time if it’s emergency. This valve should be close to the operation room.
◎ The alarm system of gas detecting is necessary to find out the gas leakage in time.

三、燃气管道要求 Requirements for Gas pipe

◎燃气管道要求用无缝钢管，管壁不应过薄，接头处必须密封可靠，管道连接后要用燃气检测仪或是肥皂水检测管线渗漏情况。

◎定期检查阀门和管道，应无燃气泄漏情况、无管道破损情况。
 
◎ All the gas pipes should adopt seamless steel tube, the pipe well should not be very thin, the connector of pipe should be sealed tightly. After connecting, please detect the leakage situation by gas detector or soap suds.
◎ Check the valve and pipe regularly, make sure there is no leakage and breakage situation.
