做好電廠電氣設備故障檢修不僅可以讓電廠始終處于安全運行中，還可以提高用戶對電廠工作的滿意度。對于電廠電氣設備來說，如果出現故障，就不能為用戶提供電能，用戶生產生活將陷入癱瘓狀態。而做好故障檢修，就可以及時發現隱藏在電氣設備內部的隱患，且將隱患排除，進而為用戶提供不間斷供電，滿足用戶需求，社會生產也不會停止，由此可見，做好電氣設備故障檢修具有非凡意義。

To do a good job of electrical equipment troubleshooting can not only make the power plant always in safe operation, but also improve the user's satisfaction with the work of the power plant. For the power plant electrical equipment, if there is a fault, it can not provide power for users, and the production and life of users will be paralyzed. And do a good job of troubleshooting, you can find hidden dangers in the electrical equipment in time, and eliminate the hidden dangers, and then provide users with uninterrupted power supply, meet the needs of users, social production will not stop, it can be seen that doing a good job of electrical equipment troubleshooting has special significance.

設備故障

equipment failure 

在電氣設備運行一段時間以后，難免會受到磨損或干擾，如果不能及時排除，將威脅到電氣設備安全運行。但要解決電氣故障，就要了解電氣設備常見故障有哪些：

After the electrical equipment runs for a period of time, it will inevitably be worn or interfered. If it cannot be eliminated in time, it will threaten the safe operation of electrical equipment. But in order to solve the electrical fault, it is necessary to understand the common faults of electrical equipment

（1）短路。

(1) Short circuit.

導致電氣設備出現短路的主要原因在于絕緣層不再具有絕緣能力，而引發這種情況產生的原因則在于絕緣層受潮或磨損，有些則是線路使用時間過長出現了絕緣層老化的情況，再加上電氣設備年久失修也會發生短路。

The main reason for short circuit of electrical equipment is that the insulation layer no longer has insulation ability, and the reason for this situation is that the insulation layer is damp or worn. Some of them are that the insulation layer is aging due to the long service time of the line, and the electrical equipment is out of repair for a long time.
                             

（2）溫度過高。

(2) The temperature is too high.

對電氣設備來說，在運行中一定需要導線，但每種導線都有自己的限高承受電流負荷范圍，如果電流負荷異常，超出導線原有承受能力，就會瞬間提高導線溫度，進而將導線燒毀。之所以會出現這種情況可能與設備長期運行后缺少潤滑油有關，同時，也可能是設備運行空間過小，無法及時將熱量散發出去，也會出現這種情況。此外，沒有及時為設備清理灰塵與雜物，也會導致溫度過高，進而威脅到電氣設備安全。

For electrical equipment, wires must be needed in operation, but each kind of wire has its own height limit to bear the current load range. If the current load is abnormal and exceeds the original bearing capacity of the wire, the temperature of the wire will be increased instantly, and then the wire will be burned. The reason for this situation may be related to the lack of lubricating oil after long-term operation of the equipment. At the same time, it may also be that the operation space of the equipment is too small to emit heat in time. In addition, the failure to clean the dust and debris for the equipment in time will also lead to high temperature, which will threaten the safety of electrical equipment.

（3）電弧與電火花。

(3) Arc and spark.

在電氣設備運行中，很容易應導線絕緣層破壞等產生電弧與電火花，一旦發生這種情況，將直接威脅到電廠整體安全，尤其是電火花容易引發電失火，處理難度非常大。

In the operation of electrical equipment, it is easy to produce arc and electric spark due to the damage of wire insulation. Once this happens, it will directly threaten the overall safety of the power plant, especially the electric spark is easy to cause electric fire, which is very difficult to deal with.

（4）諧波引發故障。

(4) Harmonics cause faults.

在電子設備運行中，難免會產生諧波，這些諧波對電子設備的影響很大，更會引發誤動作，容易給電氣設備安全運行帶來威脅，更會威脅到電流運行，不利于電網質量的提升。

In the operation of electronic equipment, it is inevitable to produce harmonics. These harmonics have a great impact on electronic equipment, and even cause misoperation, which is easy to bring threats to the safe operation of electrical equipment and current operation, which is not conducive to the improvement of power grid quality.
