一、组成设备不同。
1、 The components are different.
1、电气成套设备是在电力系统中对发电机、变压器、电力线路、断路器等设备的统称。
1. Electrical equipment is a general term for generator, transformer, power line, circuit breaker and other equipment in power system.
2、电力设备主要包括发电设备和供电设备两大类，发电设备主要是电站锅炉、蒸汽轮机、燃气轮机、水轮机、发电机、变压器等等，供电设备主要是各种电压等级的输电线路、互感器、接触器等等。
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、包含设备不同
2、 Including different devices
1、电力设备主要包括箱式变压器，高低压开关柜。
1. Power equipment mainly includes box type transformer, high and low voltage switch cabinet.
2、电气设备主要包括发电机、变压器、线路、断路器等。
2. Electrical equipment mainly includes generators, transformers, lines, circuit breakers, etc.
三、设备检修不同
3、 Different equipment maintenance
1、电气设备
1. Electrical equipment
（1）短路。
(1) Short circuit.
导致电气设备出现短路的主要原因在于绝缘层不再具有绝缘能力，而引发这种情况产生的原因则在于绝缘层受潮或磨损，有些则是线路使用时间过长出现了绝缘层老化的情况，再加上电气设备年久失修也会发生短路。
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）温度过高。
(2) The temperature is too high.
对电气设备来说，在运行中一定需要导线，但每种导线都有自己的高承受电流负荷范围，如果电流负荷异常，超出导线原有承受能力，就会瞬间提高导线温度，进而将导线烧毁。
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.
之所以会出现这种情况可能与设备长期运行后缺少润滑油有关，同时，也可能是设备运行空间过小，无法及时将热量散发出去，也会出现这种情况。此外，没有及时为设备清理灰尘与杂物，也会导致温度过高，进而威胁到电气设备。
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）电弧与电火花。
(3) Arc and spark.
在电气设备运行中，很容易应导线绝缘层破坏等产生电弧与电火花，一旦发生这种情况，将直接威胁到电厂整体，尤其是电火花容易引发电失火，处理难度很大。
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、电力设备
2. Electrical equipment
电力二次设备构成的是一个系统，不仅仅是装置本身，如交流、直流、控制回路等，由于部分回路还没有监测手段，对设备状态无法进行实时的技术分析判断。
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.
