一、組成設(shè)備不同。
1、 The components are different.
1、電氣成套設(shè)備是在電力系統(tǒng)中對(duì)發(fā)電機(jī)、變壓器、電力線(xiàn)路、斷路器等設(shè)備的統(tǒng)稱(chēng)。
1. Electrical equipment is a general term for generator, transformer, power line, circuit breaker and other equipment in power system.
2、電力設(shè)備主要包括發(fā)電設(shè)備和供電設(shè)備兩大類(lèi)，發(fā)電設(shè)備主要是電站鍋爐、蒸汽輪機(jī)、燃?xì)廨啓C(jī)、水輪機(jī)、發(fā)電機(jī)、變壓器等等，供電設(shè)備主要是各種電壓等級(jí)的輸電線(xiàn)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(shè)備不同
2、 Including different devices
1、電力設(shè)備主要包括箱式變壓器，高低壓開(kāi)關(guān)柜。
1. Power equipment mainly includes box type transformer, high and low voltage switch cabinet.
2、電氣設(shè)備主要包括發(fā)電機(jī)、變壓器、線(xiàn)路、斷路器等。
2. Electrical equipment mainly includes generators, transformers, lines, circuit breakers, etc.
三、設(shè)備檢修不同
3、 Different equipment maintenance
1、電氣設(shè)備
1. Electrical equipment
（1）短路。
(1) Short circuit.
導(dǎo)致電氣設(shè)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(xiàn)路使用時(shí)間過(guò)長(zhǎng)出現(xiàn)了絕緣層老化的情況，再加上電氣設(shè)備年久失修也會(huì)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(guò)高。
(2) The temperature is too high.
對(duì)電氣設(shè)備來(lái)說(shuō)，在運(yùn)行中一定需要導(dǎo)線(xiàn)，但每種導(dǎo)線(xiàn)都有自己的高承受電流負(fù)荷范圍，如果電流負(fù)荷異常，超出導(dǎo)線(xiàn)原有承受能力，就會(huì)瞬間提高導(dǎo)線(xiàn)溫度，進(jìn)而將導(dǎo)線(xiàn)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(huì)出現(xiàn)這種情況可能與設(shè)備長(zhǎng)期運(yùn)行后缺少潤(rùn)滑油有關(guān)，同時(shí)，也可能是設(shè)備運(yùn)行空間過(guò)小，無(wú)法及時(shí)將熱量散發(fā)出去，也會(huì)出現(xiàn)這種情況。此外，沒(méi)有及時(shí)為設(shè)備清理灰塵與雜物，也會(huì)導(dǎo)致溫度過(guò)高，進(jìn)而威脅到電氣設(shè)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(shè)備運(yùn)行中，很容易應(yīng)導(dǎo)線(xiàn)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(shè)備
2. Electrical equipment
電力二次設(shè)備構(gòu)成的是一個(gè)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(méi)有監(jiān)測(cè)手段，對(duì)設(shè)備狀態(tài)無(wú)法進(jìn)行實(shí)時(shí)的技術(shù)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.
