防止發電機組產生過高電壓，是安全運行的必要條件。為此要做到什么呢？下面瓦斯發電機組廠家為您進行解答。

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.原動機的轉速要在15秒內，由慢到快逐漸達到發電機組的額定轉速。原動機的轉速要恒定，調節要靈活。在減速后要避免驟然提高轉速，使電壓升高過快。

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.斷開負載開關后，必須及時斷開相應的輔助電容器開關。

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

3.當用電電路的負載由電動機改為照明時，切莫忘記了斷開電動機的無功補償電容器，否則會導致激磁電流增大，電壓升高，產生過電壓。

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.電容器應無漏油、缺油、打火、拉弧等不正常現象。當電容器與電源斷開后，在其板上仍然保持一定的殘留電壓，在三相交流電路中，可能達到網絡電壓2倍左右，如果人體觸及后果是非常嚴重的。所以更換或檢修電容器時，應采用可靠的接地將電容器多次放電。

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.在著雷較多的區域運行的發電機組，架空輸電線路較長(500m左右)時，應在發電機組出口的首、末端桿塔上，安裝二組FSl-0.5型低壓閥型避雷器，并可靠接地，其接地電阻值應小于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.

綜上所述，機房內的開關、電容器、電動機等要明顯注用途并編號，以防誤操作。制定相應的發電機組操作運行規程，以確保發電機組的安全運行為宗旨。更多相關內容就來我們網站http://pyucoin.com咨詢吧！

To sum up, switches, capacitors, motors, etc. in the machine room should be clearly marked and numbered to prevent misoperation.
