作为一名电气成套维修人员来说，在遇到电气故障时，能准确查明故障原因，合理正确地排除故障，对提高劳动生产率，减少经济损失和生产都具有重大意义。下面来讲解几种排除故障的方式：

As a complete set of electrical maintenance personnel, it is of great significance for improving labor productivity, reducing economic losses and safe production to be able to accurately identify the cause of the failure and reasonably and correctly remove the failure when encountering electrical failure. Here are some troubleshooting methods:

一、电阻测试法

1、 Resistance test method

电阻测试法是一种常用的测量方法。通常是指利用万用表的电阻档，测量电机、线路、触头等是否符合使用标称值以及是否通断的一种方法，或用兆欧表测量相与相、相与地之间的绝缘电阻等。测量时，注意选择所使用的量程与校对表的准确性，一般使用电阻法测量时通用做法是先选用低档，同时要注意被测线路是否有回路，并严禁带电测量。

The resistance test method is a common measurement method. It usually refers to a method of measuring whether the motor, line, contact, etc. conform to the nominal value of use and whether they are on or off by using the resistance range of a multimeter, or measuring the insulation resistance between phases and between phases and between phases and ground with a megohmmeter. When measuring, pay attention to the accuracy of the range used and the calibration meter. Generally, when using the resistance method to measure, the general practice is to select the low gear first, and at the same time, pay attention to whether the measured line has a circuit, and live measurement is strictly prohibited.

二、电压测试法

2、 Voltage test method

电压测试法是指利用万用表相应的电压档，测量电路中电压值的一种方法。通常测量时，有时测量电源、负载的电压，有时也测量开路电压，以判断线路是否正常。测量时应注意表的档位，选择合适的量程，一般测量未知交流或开路电压时通常选用电压的高档，以确保不于在高电压低量程下进行操作，以免把表损坏；同时测量直流时，要注意正负极性。

Voltage test method refers to a method of measuring the voltage value in the circuit by using the corresponding voltage range of the multimeter. Usually, the voltage of power supply and load is measured sometimes, and the open-circuit voltage is also measured sometimes to judge whether the circuit is normal. When measuring, pay attention to the gear position of the meter and select the appropriate range. Generally, when measuring unknown AC or open-circuit voltage, the high range of voltage is usually selected to ensure that the operation is not carried out under high voltage and low range, so as to avoid damaging the meter; When measuring DC at the same time, pay attention to the positive and negative polarity.

三、电流测试法

3、 Current test method

电流测试法是通常测量线路中的电流是否符合正常值，以判断故障原因的一种方法。对弱电回路，常采用将电流表或万用表电流档串接在电路中进行测量；对强电回路，常采用钳形电流表检测。

The current test method is usually used to measure whether the current in the circuit conforms to the normal value to determine the cause of the fault. For the weak current circuit, the ammeter or multimeter current range is often connected in series in the circuit for measurement; Clamp ammeter is often used for detection of strong current circuit.

四、仪器测试法

4、 Instrument test method

借助各种仪器仪表测量各种参数，如用示波器观察波形及参数的变化，以便分析故障的原因，多用于弱电线路中。

Measure various parameters with the help of various instruments and meters, such as observing the waveform and parameter changes with an oscilloscope, so as to analyze the cause of the fault, which is mostly used in weak current lines.

五、常规检查法

5、 Routine inspection method

依靠人的感觉器官(如：有的电气设备在使用中有烧焦的糊味，打火、放电的现象等)并借助于～些简单的仪器(如：万用表)来寻找故障原因。这种方法在维修中常用，也是采用的。

Find out the cause of failure by relying on human sense organs (such as some electrical equipment with burnt smell, ignition, discharge, etc.) and some simple instruments (such as multimeter). This method is commonly used in maintenance and is also the first one to be used.

六、更换原配件法

6、 Replacement of original parts

即在怀疑某个器件或电路板有故障，但不能确定，且有代用件时，可替换试验，看故障是否消失，恢复正常。

That is, when a certain device or circuit board is suspected to have a fault, but cannot be determined, and there are substitute parts, the test can be replaced to see whether the fault disappears and returns to normal.

在实际工作中，排除故障的方法及方式只能根据故障的具体情况而定，也没有什么严格的模式及方法，对部分维修人员来说会感到困难，在排除故障的过程中，往往会走不少弯路，甚造成较大损失。以上方式希望给您帮助，更多事项就来我们网站http://www.tongyuhengcheng.com咨询吧！

In actual work, the method and method of troubleshooting can only be determined according to the specific situation of the fault, and there is no strict mode and method, which will be difficult for some maintenance personnel. In the process of troubleshooting, there are often many detours, and even large losses. We hope to help you with the above methods.
