一、組成設備不同。
1、 The components are different.
1、電氣成套設備是在電力系統(tǒng)中對發(fā)電機、變壓器、電力線路、斷路器等設備的統(tǒng)稱。
1. Electrical equipment is a general term for generator, transformer, power line, circuit breaker and other equipment in power system.
2、電力設備主要包括發(fā)電設備和供電設備兩大類，發(fā)電設備主要是電站鍋爐、蒸汽輪機、燃氣輪機、水輪機、發(fā)電機、變壓器等等，供電設備主要是各種電壓等級的輸電線路、互感器、接觸器等等。
2. Power equipment mainly includes power generation equipment and power supply equipment. Power generation equipment mainly includes power station boiler, steam turbine, gas turbine, water turbine, generator, transformer and so on. Power supply equipment mainly includes transmission lines, mutual inductors, contactors and so on of various voltage levels.
二、包含設備不同
2、 Including different devices
1、電力設備主要包括箱式變壓器，高低壓開關柜。
1. Power equipment mainly includes box type transformer, high and low voltage switch cabinet.
2、電氣設備主要包括發(fā)電機、變壓器、線路、斷路器等。
2. Electrical equipment mainly includes generators, transformers, lines, circuit breakers, etc.
三、設備檢修不同
3、 Different equipment maintenance
1、電氣設備
1. Electrical equipment
（1）短路。
(1) Short circuit.
導致電氣設備出現(xiàn)短路的主要原因在于絕緣層不再具有絕緣能力，而引發(fā)這種情況產(chǎn)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(xiàn)了絕緣層老化的情況，再加上電氣設備年久失修也會發(fā)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。
For electrical equipment, wires must be needed in operation, but each kind of wire has its own high 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.
之所以會出現(xiàn)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(fā)出去，也會出現(xiàn)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。
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(chǎn)生電弧與電火花，一旦發(fā)生這種情況，將直接威脅到電廠整體，尤其是電火花容易引發(fā)電失火，處理難度很大。
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.
2、電力設備
2. Electrical equipment
電力二次設備構成的是一個系統(tǒng)，不僅僅是裝置本身，如交流、直流、控制回路等，由于部分回路還沒有監(jiān)測手段，對設備狀態(tài)無法進行實時的技術分析判斷。
Power secondary equipment is a system, not only the device itself, such as AC, DC, control circuit, etc. because some circuits have no monitoring means, it is impossible to make real-time technical analysis and judgment on the equipment status.
