放置了半年的焦化发电机组需要做哪些检测呢？实际上不算很难，一般的要做以下几点检查：

What tests should be done for the coking generator set that has been placed for half a year? In fact, it is not very difficult. Generally, the following checks are required:

1、检查机组的启动成功率

1. Check the startup success rate of the unit

试验方法：试验应在符合产品技术条件规定的准备启动状态下，每给一个启动指令，启动成功后突加功率为1.0的50% 的额定负载运行5min，再停机。试验100次。启动成功率应大于99%。否则，则认为此项不合格。

Test method: the test shall be carried out in the ready to start state in accordance with the technical conditions of the product. After each start command is given, the test shall be conducted with 50% of the rated load of 1.0 for 5min and then shut down. 100 tests. The startup success rate shall be greater than 99%. Otherwise, it is considered as unqualified.

2、检查机组平均故障间隔期

2. Check the mean time between failures of the unit

检查方法：机组带cosФ=0.8的额定负载，连续或累计运行1000h以上，焦化机、发电机均不应出现故障，控制电路的 元件不应出现二次以上故障，否则，则认为此项不合格。此项指标允许在实际运行中进行考核。

Inspection method: unit with cos Ф= 0.8 rated load, continuous or cumulative operation for more than 1000h, the coking machine and generator shall not have fault, and the elements of the control circuit shall not have more than two faults, otherwise, this item is considered unqualified. This indicator can be evaluated in actual operation.

3、检查机组带可控硅负载的运行情况

3. Check the operation of the unit with thyristor load

试验方法：机组带cosФ≥0.5的三相可控硅整流器负载，在机组额定容量的10%～50%范围内任一点上均应能稳定工作 。如果产生低频振荡，应实行调整，使之能稳定工作，否则认为此项不合格。

Test method: unit with cos Ф The load of three-phase thyristor rectifier ≥ 0.5 shall be able to work stably at any point within the range of 10% ~ 50% of the rated capacity of the unit. If low-frequency oscillation occurs, it shall be adjusted to make it work stably. Otherwise, it is considered unqualified.

4、检查自动化机组的联动试

4. Check the linkage test of the automatic unit

检查方法：两台机组应互为主备用，任选一台作主用，人为切断市电，主用机组自动启动成功后供电。制造一个故障 ，使主用机组自动停机备用机组则应自动成功后供电。使市电恢复后，备用机组应级自动停机。如不合格，找出原因，排 除故障。两台机组分别为主用，复试三次，如仍有一次不合格，则认为此项不合格。

Inspection method: two units shall be used as main and standby for each other, and one unit shall be selected as the main one. The mains power shall be cut off manually, and the power supply shall be supplied after the main unit is automatically started successfully. If a fault is caused, the main unit will automatically shut down, and the standby unit will automatically supply power after success. After the mains power is restored, the standby unit shall stop automatically. If unqualified, find out the reason and eliminate the fault. The two units are mainly used and retested for three times. If one is still unqualified, it is considered as unqualified.

5、检查自动化焦化发电机组自动启动功能

5. Check the automatic startup function of the automatic coking generator set

试验方法：接通启动电源，将机组工作方式选择开关搬向自动，送入启动指令，并且人为使机组启动不成功，机组应 自动启动三次。

Test method: connect the startup power supply, move the unit working mode selection switch to automatic, and send the startup command. If the unit fails to be started manually, the unit shall be started automatically for three times.

试验三次，只要有一次不合格，复试次数加倍，若仍有一次不合格，则认为此项不合格。

If one of the three tests is unqualified, the number of retests shall be doubled. If there is still one unqualified, it is considered to be unqualified.

6、检查自动化机组的自动补给装置

6. Check the automatic supply device of the automatic unit

试验方法：在控制电路电路完全联结完毕后，将工作方式选择开关搬向自动人为放水放油至低液位，应能自动补给， 当液面上升到高液位时补给应能自动停止。

Test method: after the control circuit is fully connected, move the working mode selection switch to automatic manual water and oil drainage to the low level, which shall be able to automatically replenish. When the liquid level rises to the high level, the replenishment shall be able to automatically stop.

试验三次，只要有一次不合格，复试次数加倍，若仍有一次不合格，则认为此项不合格。

If one of the three tests is unqualified, the number of retests shall be doubled. If there is still one unqualified, it is considered to be unqualified.

此外也要检查自动化机组的保护性、检查自动化机组的冷却水、机油加热等事项，更多检查项目合格才能进行下一步 使用，详情就来我们网站http://www.huannengpower.com联系了解吧。

In addition, it is also necessary to check the protection of the automatic unit, check the cooling water and oil heating of the automatic unit. More inspection items can be used in the next step only if they are qualified. Please visit our website for details http://www.huannengpower. Contact me to understand.
