防止发电机组产生过高电压，是安全运行的必要条件。为此要做到什么呢？下面瓦斯发电机组厂家为您进行解答。

It is a necessary condition for safe operation to prevent generating sets from generating excessive voltage. What should we do for this? The manufacturer of gas generator set will answer for you.

1.原动机的转速要在15秒内，由慢到快逐渐达到发电机组的额定转速。原动机的转速要恒定，调节要灵活。在减速后要避免骤然提高转速，使电压升高过快。

1. The speed of the prime mover should gradually reach the rated speed of the generator set from slow to fast within 15 seconds. The speed of the prime mover should be constant and the adjustment should be flexible. After decelerating, it is necessary to avoid sudden increase of speed, so that the voltage rises too fast.

2.断开负载开关后，必须及时断开相应的辅助电容器开关。

2. After the load switch is disconnected, the corresponding auxiliary capacitor switch must be disconnected in time.

3.当用电电路的负载由电动机改为照明时，切莫忘记了断开电动机的无功补偿电容器，否则会导致激磁电流增大，电压升高，产生过电压。

3. When the load of the electric circuit is changed from the motor to lighting, do not forget to disconnect the reactive compensation capacitor of the motor, otherwise the excitation current will increase, the voltage will rise, and overvoltage will occur.

4.电容器应无漏油、缺油、打火、拉弧等不正常现象。当电容器与电源断开后，在其板上仍然保持一定的残留电压，在三相交流电路中，可能达到网络电压2倍左右，如果人体触及后果是非常严重的。所以更换或检修电容器时，应采用可靠的接地将电容器多次放电。

4. The capacitor shall be free of abnormal phenomena such as oil leakage, lack of oil, sparking and arcing. When the capacitor is disconnected from the power supply, it still maintains a certain residual voltage on its board. In the three-phase AC circuit, it may reach about twice the network voltage. If the human body touches it, the consequences are very serious. Therefore, when replacing or repairing the capacitor, reliable grounding should be used to discharge the capacitor for many times.

5.在着雷较多的区域运行的发电机组，架空输电线路较长(500m左右)时，应在发电机组出口的首、末端杆塔上，安装二组FSl-0.5型低压阀型避雷器，并可靠接地，其接地电阻值应小于10n。

5. When the overhead transmission line of the generator set operating in the area with more lightning strikes is long (about 500m), two sets of FSl-0.5 low-voltage valve-type lightning arresters shall be installed on the first and end towers at the outlet of the generator set and reliably grounded, and the grounding resistance value shall be less than 10n.

综上所述，机房内的开关、电容器、电动机等要明显注用途并编号，以防误操作。制定相应的发电机组操作运行规程，以确保发电机组的安全运行为宗旨。更多相关内容就来我们网站http://www.huannengpower.com咨询吧！

To sum up, switches, capacitors, motors, etc. in the machine room should be clearly marked and numbered to prevent misoperation. Formulate corresponding operation regulations for generator units to ensure the safe operation of generator units. Come to our website for more relevant content http://www.huannengpower.com Ask!
